Well I recently ran into an SD card problem. To find a solution I have searched many forums and Google. None have offered any solution. On my search for answers I have found at least 100+ G1 owners with the same problem. All posting within the last month. The error we are getting is "SD card removed. insert new sd card".

All threads I have come across have suggested to reformat the sd card, repartition, use ADB, cyans recovery image, to fix this problem. None of the above solutions have worked. A majority of the threads the G1 owners were still able to use there sd card with there pc.

Now I know this is in the right section. We need a developer to figure this out. A g1 without a sd card is like a g1 that is bricked. It is horrible not being able to download, play music, shoot pictures, ect.
[G1 Q&A, Help & Troubleshooting] question.com:
i ran into this issue on a friends g1. came to find out he dropped it and the sd card would neved get seated correctly in the sd slot. i had to wiggle it a bit before the phone recognized it

I had this problem on one of the roms I was using, maybe Dude's cupcake?

Wipe of the phone fixed it.
[G1 Q&A, Help & Troubleshooting] bob50963:
I have whiped and upgraded to new roms. My problem began when I entered a command into terminal to fix another problem. After that I whiped and updated to cyans.
[G1 Q&A, Help & Troubleshooting] knowfear:
I have experienced this 1 time only. When it happened to me, I removed it from the phone completely and checked it in my card reader. It picked up on the PC just fine and everything was still intact, so I knew the card was still good. I rebooted the phone without it and then shut down. Reinserted the card in the phone and booted into recovery. I ran the fix partitions thing and rebooted again. Problem solved. I personally haven't had any other problems since then. I was told on another forum as well that when you flash a new rom or even a new theme to run the partition fix included with cyans recovery. Something to do with apps2sd I think? I have just gotten into that habit and no more issues. Good luck.
[G1 Q&A, Help & Troubleshooting] bob50963:
I think I might have changed a path on my phone while in terminal and thats what is causing my problem. I can't get cyans recovery because my phone isn't reading the sdcard for me to install it. Also, good post I am sure your solution will help many!
[G1 Q&A, Help & Troubleshooting] prof2:
Same for me. With Dude's it wouldn't read my SD card. Wiped, installed Cyanogen's ROM, wiped again, and the problem instantly went away.
[G1 Q&A, Help & Troubleshooting] anonymoustom:
Have you tried another SD card in the device? One that you know is good and working in another unit. I screwed up one of my older smaller cards trying to make a Goldcard. It has never worked since. :(
[G1 Q&A, Help & Troubleshooting] bob50963:
I tried that a few days ago. No luck there. Im glad were getting this thread going. So far I see a lot of good solutions. Best part about this is all the information is all in one place! If anyone has any input please do tell.
[G1 Q&A, Help & Troubleshooting] knowfear:
Do you have another card to test out? Have you tried to mount/unmount the card with the phone on? I know if a rom has built in apps2sd the unmount/format option is grayed out. Maybe try to take the card out with the phone on and reboot and then put it back in? Not sure what all to try. I know I was frustrated when mine was doing that as well.
[G1 Q&A, Help & Troubleshooting] rembonjaski:
This would happen to me all the time with the camera. I would take two or three photos, then I'd get a message that I need to insert an SD card.

I think the problem was the card. I was using a Patriot 4GB Class 6 card from Fry's. I switched to a Transcend 8GB Class 6 card and have not had any problems since.

It sucks having to buy a new card if you already have one, but $18 for a good quality 8gb card is pretty reasonable.
[G1 Q&A, Help & Troubleshooting] joe v:
I have class6 card that does this.. I also have other card that don't .. in the case with my class 6 card it works fine untill I use it for apps to sd, wich in my case renders it useless..

It's word cuz it will load everything fine and run, but then freez up in the middle of use. That's when I know it unmounted itself. Then I'm forced to pull battary out or reboot.. I have truer every methed to fix it with no luck...
[G1 Q&A, Help & Troubleshooting] knowfear:
Mine is a 4gb c6 card and other than the 1 time, I've had no further problems. I have run A2SD for quite a while even before it was included with different roms.
[G1 Q&A, Help & Troubleshooting] NPS_CA:
First comment: Why is this in this section.

Most of these I've seen have been mechanical (poor card seating) - poor card contacts. Swapping the card has always removed the issue for me.
[G1 Q&A, Help & Troubleshooting] alapapa:
I've had 2 cheaper sd cards go bad. they looked like they worked fine when i put them in a card reader and plugged into a linux box -- but only at first glance.

further inspection revealed bad sectors and damage to the storage. Since i got a nice class 6, it has seemed fine -- i think you get what you pay for a lot of times.

Not to be crass, but this does not belong in this section of the board. Just because one seeks the expertise of developer, doesn't make it ok to post a thread in this forum.

My $.02
[G1 Q&A, Help & Troubleshooting] joe v:
I agree, I also think it was cards that were just made bad I guess that's what I get for buying a cheap class 6 transcend from target lol..

Bad SD Card Slot

This happened to me to a week ago after flashing a new Rom, thought I do not think that the flashing had anything to do with it. I tried everything wiggling it , cleaning connection, reformatting. The card worked in other phones and computer but mine. I just think it went bad. Nevertheless after 5 days of getting no where I had T-Mobile send me a replacement
[G1 Q&A, Help & Troubleshooting] swaggle:
I should add that I also tried 2 new card as well both class 6
[G1 Q&A, Help & Troubleshooting] bob50963:
this is in the right section. If you havent noticed this a spread problem among many. We have tried other Sd cards. They do not work. This is a internal problem. Thats why its in the developers section. This post will save others from having to post about this same issues if they can find all the answers here. That being said if you have a problem with it maybe you should explain to me why brick threads, ect are ok in this section? There is nothing wrong with my sd card. Just like there isnt anything wrong with the other 5 sd cards I tried.

Google this you will find a lot of people having the same problem.
[G1 Q&A, Help & Troubleshooting] Jrbourque:
You dont need a sdcard to flash the new recovery, just use fastboot
[G1 Q&A, Help & Troubleshooting] alapapa:
google what, exactly?

as others have said...sounds like the reader in your (& the 100+ you've found) is on the fritz.

this thread is in the wrong section because it offers nothing toward the development of the android operating system on the Dream platform.

to answer your question about the brick threads:

1) two wrongs don't make a right

2) most "brick" threads posted in this section are locked or moved

3) the "brick" threads that still live here are narrowly focused at solving a particular software problem that arose from flashing gone awry.

if you've tried different ROMs and different sd cards with the same results, how can it be anything other than the reader or some other piece of hardware..?
[G1 Q&A, Help & Troubleshooting] jugg2000:
I feel your pain.

Now... what if it is a faulty hardware problem with the G1? I can imagine most of us in here constantly insert and extract our sdcards for flashing and other things. Normal users don't wear out the mechanics of the sdcard reader in the phone like most of us do. I hope that's not the case, but it's not far fetched.

A good question to ask is how often have you all been removing your sdcards for flashing? We may find a common denominator in this situation.
[G1 Q&A, Help & Troubleshooting] bob50963:
This is a software issue. So its in the right section. I dont think its hardware related. Its not the rom either. What ever software it uses to communicate from the reader to the operating system is corrupted or maybe the paths have been changed. Dude I have had this problem for a week now trust me I know what im talking about ive been to countless threads. If you ran into the same problem you can not say you wouldn't start a thread like this. If you post this in other sections your likely to not get a response or only a few repsonse that offers no solution to fix this problem. You can not say other wise or for sure YOUR A BSER! Anyways you dont know what its like not having your sdcard port working.

Also, my card keeps creating random .dm files.
[G1 Q&A, Help & Troubleshooting] Jrbourque:
Okay so here is the main question.

Is this happening with more than one sdcard? Not other peoples just you. Have You tried different cards?

and what happens when you try cyans recovery img and repair the sdcard?
[G1 Q&A, Help & Troubleshooting] cunami:
I also had similar experience - card was mounted via USB, I've copied few files from Linux into it, also renamed one folder there directly - and after unmounting I've got error message that filesystem contains errors and Android won't give me SD card back for using it from apps... I was suggested to format the card. Running filesystem checks always failed and I couldn't repair it...

Although I could "mount /sdcard" from terminal app and were able to see files on it, but Android automatically always refused to use the card. The only possible way to make it work properly again - was repartitioning and formatting everything cleanly after. Was a bit pain - had to reinstall all apps and so on...

Good that at least I could backup all data using "mount /sdcard" + "adb pull" before partitioning... Since then card works good for few weeks already - would be hard to believe that it could been caused by hardware issues? For me looks more like software problem.
[G1 Q&A, Help & Troubleshooting] dan0zone:
You caused this ,but you want someone else to fix it for you?

Buddy you need to calm down , this needs to be in the Q&A section and you need to get a new phone ...

This should be a lesson, be careful when you enter commands .. lesson learnt MOVE ON
[G1 Q&A, Help & Troubleshooting] Jrbourque:
Also wondering if you have tried to repair the file system and if it fails to type this command in console

#e2fsck /dev/block/mmcblk0p2

thats about it lol
[G1 Q&A, Help & Troubleshooting] osho741:
Its entierly possible that the sd card hardware, the slot that you put the sd card into is simply dieing prematurely. Perhaps the lunix swap, apps2sd are causeing the hardware to fail prematurely on g1s.
[G1 Q&A, Help & Troubleshooting] 51dusty:
i'll take a stab at it

this thread may not be in the right forum, but devs may have expertise that is not found in other forums. i, for one, do not really cruise the general Q&A thread(:rolleyes:) often, but i check this forum >three times a day. :D

anyway...i've never had this problem, however, some people post here and here about these symptoms and the various errors("ERROR: input/output error during write on /dev/block/mmcblk0", among others) they receive while trying to partition their sdcard. there may be a link between the errors seen in console while partitioning and the sdcard being shown bad in android.

my $0.02:

*make sure sdcard's partition 1 is aligned to cylinder boundaries

*make sure table type of sdcard is msdos...not loop

*could it be caused by inserting into a computer? i know windows and mac like to do the mexican hat dance on my sdcard and leave trash files all over the place.:mad:

*things to consider: this happens only to people who use a card reader?(i don't) this happens to people with a particular operating system?

*is there a particular brand/size/class this is happening with? there are many people who have had great difficulty with 16gb Transcend cards in the threads above.

*maybe someone could start a thread(somewhere else :D...Q&A thread i'm looking in your direction) where people with this problem can report their data, NOT their PROBLEMS, so it could be analyzed. include rom, spl, sdcard size/brand/class/pn, partition information, card reader y/n, os,...whatever is deemed important.
[G1 Q&A, Help & Troubleshooting] jaaronmoody:
my thoughts are..... yes, it's in the wrong forum, but... to help,

if you have tried more than one good sdcard in your device and it's not working, you either have to properly format said sdcards in the device, or you have a problem with the physical connection between the sdcard and the phone. and i worked at radioshack..... so i know everything. and ....reported
[G1 Q&A, Help & Troubleshooting] n1ghtl1fe:
I had same problem few months back and it scared the **** out of me cuz i thought G1 was the problem.

I used Acronis Disk Director and full wiped sd card. Not just deleted things but wiped. It basically goes over each sector on sd and completely wipes any traces of data. You pick how many times to pass i choose 3. Took about an hour.

Took care of problem, every now and then i do it still when switching between roms (just 1 pass).

Hope this helps
[G1 Q&A, Help & Troubleshooting] Ducter:
I had a issue, close to what your explaining however my phone would see and read the card most of the time but connecting to pc it wouldnt show up, or give the option to mount and adb wouldnt work either, putting sd card in my sons g1 all worked well. Ended up calling t-mobile and since I was just shy of my year they sent me a new one.
[G1 Q&A, Help & Troubleshooting] All~G1:
Well put sir!!!
[G1 Q&A, Help & Troubleshooting] wergeld:
This happend to me as well.

I downloaded a file in the browser and used Astro to move it to the root of the sdcard.

I rebooted into recovery, and attempted to apply the update and that is when it returned the error that it couldn't access mmcblk0p2.

When booting all the way into android it said that the sdcard had been removed.

I am using CM 4.0.4 on a Transcend 8gb class 6 card with apps2sd with a 500mb partition and a 32mb linux-swap partition (the rest is fat32).

I tried to use CM recovery 1.4 with the fix partitions option. It said it completed repairing partitions.

I mounted the sdcard (again from the recovery console) and it returned no errors. So I adb pushed a file to the sdcard....it "worked" for a bit. then returned to prompt. I did and ls -al on the sdcard from the adb shell and it showed the file.

I then rebooted into android and it still said that the sdcard was removed.

sigh....

So I went down to the ComUSA (lucky for me TigerDirect bought out one of the locations where I live) and picked up another 8gb class 6 Transcend card.

Did the partition formatting again (a la parted from 51dusty's post), installed the apps I use a lot, and I am back in business.

Only "new" app before my restart of the phone when the sdcard broke was Pandora....I _love_ this app so I hope it didn't cause the issues.
[G1 Q&A, Help & Troubleshooting] he3:
Please try the windows drive manager.

Delete all partitions on the card and then create a new one for the whole card (fat32)

Now the card is like brand new.

Just for giggles, what size partitions are you using and what commands are you executing to create the partitions,
[G1 Q&A, Help & Troubleshooting] wergeld:
Cannot use windows drive manager since the card does not mount...since I am doing all this from android. I do not have a card reader.

Partitions made using the post on using parted:

32mb swap

500 ext2 (upgraded to ext3)

rest of 8gb is fat32

Yes it is set as msdos and not loop. Yes the "cylinders" match. Yes, yes, yes I do love the beer, but that is not the reason this broke =)
[G1 Q&A, Help & Troubleshooting] bruce_wayne:
When I had this problem a temporary solution was to remove and re-insert the sd card whilst phone was on. I know this shouldn't be done but hey it would fix the issue and the sd card would be picked up untill next boot. (I don't have apps 2 sd set up or a swap or any partitions so this had no negative effect for my g1 or sd card as it is not being used as internal memory)

The full solution for me was to re flash the rom. Once the rom was reflashed (didn't even have to wipe) I've had no issues with sd card and it works fine every boot.
[G1 Q&A, Help & Troubleshooting] magicman1987:
same here, same problem, reformat, wipe and installed a stable version of cyanogens, working fine with no problems apart from occasional "crash" which is a problem with the rom.

should wipe and reflash, if this does not work, probably a issue with your hardware.
[G1 Q&A, Help & Troubleshooting] he3:
Is it possible to put the cards in upside down...

Try removing and reinsert the sim?
[G1 Q&A, Help & Troubleshooting] wergeld:
yep, its possible...
[G1 Q&A, Help & Troubleshooting] h.nocturna:
Just because you guys need the expertise of a developer, it doesn't mean that it belongs in the Development Forum unless it is definitely ROM related (in which case you should be posting within the thread of the ROM as a bug). I have feelings about this issue too (one of my G1's is currently collecting dust because I cannot get the sdcard to work), but at the same time you don't see me spamming the dev thread for answers.

Anyways, to contribute to the thread (though I am reporting it to get it moved), this is most likely some type of hardware error unrelated to the software of the phone. Steps you can take to check:

Wipe the whole sdcard over again like others have suggested

Create a new fat32 partition over it

Test the sdcard slot with another sdcard to see if the problem is related to the phone or the card itself. If the 2nd card doesn't read either, then its very likely just a broken card slot.

Can the phone read the card in bootloader/recovery? If they can, I would repartition it from parted.

If all else fails and you've determined its a problem with the cardslot, then I would get on the phone with whoever is handling your warranty.
[G1 Q&A, Help & Troubleshooting] jmon777:
im not a dev at all but what type of bored does your phone have? is it pvt or the other one? and also you should buy card reader if u want flash roms 10 bucks at one radio shack. (and that's steep for one)
[G1 Q&A, Help & Troubleshooting] Sumanitu:
I keep having this issue too, every once in awhile my phone will hard lock and only pulling the battery or menu + send + end will reboot the phone. When it finishes booting it says sdcard removed, removing and replacing the sdcard fixes the issue, but then every one of my apps (I'm using apps2sd) are corrupted somehow and I have to uninstall and reinstall to fix them.

It happens with either an ext2 or ext3 partition and fix_permissions and repairing the filesystem doesn't fix it. In fact, a direct copy of the *.apk files from a clean source to /data/app won't fix it either, so its something to do with android rather then the ext partition or sdcard. Does anyone know how I can repair my apps without manually uninstalling and reinstalling every single one?
[G1 Q&A, Help & Troubleshooting] bootleg16:
this is because your sd card is dead.

happened to me twice already. im already on my 3rd micro sd and they wil eventually die out if u use apps2sd or swap
[G1 Q&A, Help & Troubleshooting] h.nocturna:
Try moving all your apps to your sdcard/app then:

#install /sdcard/app/* /system/sd/app/

dunno if install works with wildcards, but you can give it a try.
[Touch Pro, Fuze ROM Development] Wordsmith9091:
Introducing: ChamUZE: An offshoot of my now-slumbering LouzeBerry ROM series, sans the "Berry" (but still with some other MobileMatt-generated goodness).

Inside, you'll find:

* Build 21222 (my favorite of the pre-visual-makeover builds).

* Manila 2.1 Revolution (1.5), skinned with 2.5-like icons.

* MobileMatt's "2.5Manilish" skin for Titanium.

* Opera 9.7, with my own "Opera Personality Switcher" to spoof User Agents and switch on/off the AT&T Proxy

* The original behavior of the camera -- where it rotates a picture based on the orientation of the device at the time it was taken (lost in many recent ROMs) See notes below).

* Some custom walls, inspired by my Chamudi (the inspiration for the name!). Also, some of my favorites collected from around and about.

* Tweaks for performance, battery savings and GPS locks.

* Assignable buttons.

* Configured out-of-the-box for a Fuze, but with ProFuze included to switch the keyboard.

Download:

ChaMUZE 100609

* Fixed issue with accidental restarts during User Customization

* Added in Marketplace (which is now live! yaaaaay!)

* Added in the HTC calculator

* Updated to a newer version of Opera 9.7 -- some neat new effects and enhancements

Please restart your device after the initial bootup -- either manually, or by adding RST: Reset to the end of your sdconfig.txt

Current changelogs and downloads will always be here, older ones will always been in the third post

Screenies (from 100109/100209):
[Touch Pro, Fuze ROM Development] Wordsmith9091:
Special notes

This ROM uses Album 3 (starting with the 092809 release) and SensorSDK3. Some people will prefer Album 2.5 or SensorSDK4, so I'm providing cabs here.

There are some gains, and some tradeoffs.

Pros (Album 2.5):

* Album 2.5 doesn't pixelate the picture on first view as Album 3.0 sometimes does

* Album 2.5 rotates image views the way many people prefer, where 3.0 does not

* Album 2.5 includes the social networking uploaders.

Cons:

* You won't have the ability to change a contact picture to one stored on your device from within the Manila contact editor or Favorites tab (it works just fine if you hit "MORE" and use Windows' own contact editor, but that saves photos at a lower resolution). The ROM already includes S2V, which can save a hi-res picture to a contact, as a workaround.

Pros (SensorSDK4)

* You can turn The G-Sensor on/off from within TF3D

* You can make any application rotate, so long as it's on SensorSDK's whitelist (which you can easily edit with G-Config)

Cons:

The camera won't auto-rotate picture orientation based on the way you held your device when you took a picture

Changelogs, and old downloads

ChaMUZE 100209 (very minor update to what's in 100109)

* Removed some redundancies in the Start Menu from the new Comm Manager

* YouTube 2.5 is now cooked directly in, instead of installed as a cab — big time-saver during initial customization, slight space-saver in the ROM

* Returned to the version of the Notification Enhancement used in previous builds

ChaMUZE 100109

* Added in the Comm Manager with Wi-Fi sharing

* Added my new Opera Personality Switcher app

* Returned to the "original" 2.5 slider icons (I just like 'em better)

* Since this ROM includes Opera 9.7, I've also placed a Opera 9.5 cab on the device for those who might prefer it. That's now located in My Documents, for easier access

* Updated to a newer version of the Notification Enhancement

* More packages are cooked directly in, instead of being installed by cabs. Should make initial customization a little faster, and save a little space

* (Maybe) solved a problem one user reported with his device restarting during User Customization -- I need feedback here on whether anyone else is having problems, and whether this fixed it.

ChaMUZE 092809a

* Switched to Album 3 (cabs for 2.5 in the next post)

* Opera 9.7 is now the default (A 9.5 16643 cab will be found in your Windows directory, if you'd rather use that)

* Updated to new, snazzy versions of the Leo TF3D slider icons

* Some new wallpapers, inspired by my Chamudi

* Fixed with 092809a: Album link was missing from the Start Menu in initial 0928 upload.

Current changelogs and downloads will always be here, older ones will always been in the third post

ChaMUZE 091609[/B]

* Initial release
