I, too am loosing you to LOST.dir....

I also have experienced all theses symptoms. This is my first post here to the forum. I have been a lurker for about a month and have gleamed LOTS of valuable information. THANK YOU!

I am a recent iPhone convert, and am still learning how to 'droid it like a man. Technical proficiency comes from patience and persistence.

I have a Samsung Galaxy Skyrocket, running 2.3.5, Kernal version 2.6.35.11

I bought my 32gb micro SD card "new in retail packaging", Kingston brand, SDHC, class 10 on eBay, and it looked like the package was opened.

When I mount my phone to my windows 7 laptop, I am able to transfer files to the SD card or the phone. I can verify it is there. However data becomes corrupted/ is moved to LOST.dir when I dismount the phone (through phone software [the orange screen]). The corruption definitely happens as I dismount the phone

Most of the data I am transferring at this time are audio books, so it is either large mp3 files, or large sets of mp3 files.

Sometimes the whole directory will disappear, along with all files. Sometimes it will appear correct, but some individual files will be 1/2 corrupted.

Just trying to chime in on the problem, as this has been my #1 problem with the phone so far. Before discovering this thread I thought my problem was user-related. I am now quite sure it is not I making the mistake.

best wishes.

My current workaround is to use Airdroid and transfer over wifi.

Or you can pull the sd card and stick it directly into the PC.

I have to disagree with most of the assumptions made in this thread, I've had this problem happen loads of times. I had this problem occur in Cupcake, Doughnut, and Éclair, primarily in samsung products. I know it's not quality of SD card because I've been using the same card in my Evo 3D for months with no trouble. it usually happens when I dump between 4-6 GB of music, photos, and videos, all with subfolders into SD card. and when FSCK isolates all of the files they are 100% usable if I rename with it's original file extension. Google, and samsung would not tell me what parameters are set in FSCK that cause it to Isolate files, and I do not know how it can be disabled/altered. Most important of all do not use FDISK in a PC to scan/fix the SD card's file system, make a copy of sd's contents on your computer as a safety, and if you have irreplaceable files try an unchk software.

Kinda messed up

I was driving today, my phone sync'ed via bluetooth to my stereo. Everything was hunky doory, until I tried to fast forward a song. The same 7 songs kept playing. I checked the music folders, and they were empty, save the songs on the phone (Epic 4G Touch). Same for all the videos/jpegs. All gone. All of it was dumped in the lost.dir directory w/no extensions.

Now, I:

1) haven't unmounted the card since I've had the phone (always hooked up to USB).

2) haven't added anything to it in the past 2 weeks or so

3) was not having any issues until that point.

4) can't understand why it didn't dump *all* the directories, only the folders containing mp3s, mp4s, avis, and jpegs. Oh, and it dumped all my nandroid backups, as well.

The card is a 32gb Samsung Class 10. So, looks like I know what I'll be doing later today (renaming files).

Wrong forum. This is NOT the Epic Touch. This is OG Epic with keyboard.
[Epic 4G General] whats77inaname:
I am aware of what forum this is. Looking @ xda, and the 'net in general, it doesn't appear that this is a device-specific issue, as much as it is an Android-related issue. This thread is the most informative thread about the subject; hence, my post.
[Epic 4G General] flastnoles11:
That's because the people with the epic 4g know their stuff!!! ;)
[Epic 4G General] whats77inaname:
*lol* You'll get no argument from me.

I'm not one to segregate information based on phone. This seems to be an issue regardless of the phone, so in actuality, if you want to be picky, this whole thread belongs in the general android section. But honestly, I really don't care much about the model, I care about resolution of the common issue :) I figure that my particular situation is informative b/c it is something that hasn't been experienced before (or @ least posted), so I posted it.

32K file size

Now everyone, seems like the temporary solution for now is to look at the file sizes then guess what file type..

But my question is, I had identified almost all, except those 32kb files that I can't Open With any standard app i know..

Can anyone explain?
[Epic 4G General] Doshambe:
The problem still exists in my class 10 SanDisk micro sd card used with Samsung galaxy s4

Any ideas for quick recovery

I say we fund and make a software to end this problem and copyright it :) anyone up for business

The software/app just has to recognise what extensions the files are and where they are supposed to go out make new files and fill them with the same extensions
[Epic 4G General] dennis97519:
Me too

There is already TrID out there, and it is free.

But a lot of times different fragments of files get shoved together, and sometimes different jpg files got put together and i see human faces cascaded with pictures of printouts that I took. And there are also a lot of 32KB and 64 Kb(I think it might be whole sector of fragments)files inside, so the main problem is how to put the fragments together.

I replied to this old thread because I am also experiencing this prpblem after upgrading my Galaxy Note II from 4.1.2 to 4.3, but I 'm not sure if it startedvafter the update. But anyway I'm losing pictures and downloads, and all kinds of strange files got dumped inside lost.dir, and most of the operations are done on the phone without any computer interferrence. Whole folders just gets renamed to μ(FRAGMENT OF FOLDER NAME)~1 and they are emptied out. This is really frustrating.

Sorry if reviving old thread is a bad habit.

Hello,

I have the same problem on a non-Samsung phone (Cat B15Q, kitkat). SD card class 10 16GB. Files (music and maps) are not deleted but they randomly becomes "empty".
[Epic 4G General] Abdulrehman130:
Same issue here.

I have a 64GB san disc SD card.

my data was corrupting slowly slowly.

Something like 1 app or 1 file.

It it was normal for me.

But on one day when I check my sd card so I was shocked my 18~25 gb data was disappeared. When i checked lost.dir so I found that it's size became 15.06GB.

Now I am googling to find any solution about recover it from that directory.

ok so i plugged my phone into my computer in fastboot and instead of the qualcomm hd-usb drivers it changed to android adb interface why is this help please!!!!
[Streak 5 Q&A, Help & Troubleshooting] passion8059:
adb is like bios so as the phone can see this via you accessing fastboot it thinks you might want to alter someting so it calls up for adb drivers so it can allow you to write. Qualcomm drivers would only apper if you need to restore something via the processor chip (QDL tool for example). If you want Qualcomm drivers to appear hold vol up and insert usb and should prompt for something like Qualcomm USB Diagnostic 9002. :o

[Desire Q&A, Help & Troubleshooting] pjd007:
Ok so I've a USB brick and I'm not able to access the SD card on my desire.

I've already tried to re enable the USB with the fastboot command but this didn't work so I've been advised to flash to RUU.

When I run cat /sys/class/mmc_host/mmc1/mmc1:*/cid I get error 'No such file or directory' and I've also tried replacing the 1's with 0's but got the same error.

I presume this is happening because the handset can't access the SD card.

Is there a way out of this ?

Really need some help.

Thanks.
[Desire Q&A, Help & Troubleshooting] reaper7881:
first make sure ur in fastboot and not hboot

then check if fastboot drivers are installed in device manager

then do fastboot devices and see if ought comes up

then fastboot oem enableqxdm 0

which will fix sd access then i need the cid of the phone to create a mtd0.img to fix the brick

so u will need to do fastboot oem boot then look for cid in the writing half way down
[Desire Q&A, Help & Troubleshooting] pjd007:
Ok so I ran it again to make sure I wasn't doing something wrong.

The phone is in fastboot mode with fastboot usb showing on the handset, below is a copy of the command prompt:

C:\Program Files (x86)\Android\android-sdk\tools>fastboot oem enableqxdm 0

...

OKAY [ 0.023s]

finished. total time: 0.023s

So it appears to have run the command ok but the SD card is still showing as un mounted, I have also tried a different SD card but this one is the stock card the handset came with.

What else can I try ? :confused:

I haven't tried with Froyo, but I have used the CM7 music app with Gingerbread/JVH. (I actually did this last night w/ Continuum 5.4)

Download the big ~200MB "initial flash" file from the CM7 thread and extract it on your computer.

You should be able to find Music.apk in either ./system/app or ./app. Drop that into the /system/app folder on your phone and set the permissions & file owner to match all the other files in that folder. I used Root Explorer, but there are certainly other ways to do this, too.
[HTC Incredible S] ila420:
I am stuck between Incredible S and Xperia Neo cant decide which one should i buy, i am switching from Samsung Wave and want to try Android, phone should be durable good camera good battery and should be fast enough to play games on it, i really like the customization on HTC but HDMI and camera is good on Neo.

Kindly suggest me which one should i get ?
[HTC Incredible S] checkbox111:
It's got to be the IS, Sony phones feel so plastic and cheap when you use them, even the screens feel like they're made of plastic, i know the back of the IS is plastic but that's it, at least it feels solid when you hold it.

You can customise the UI to almost anything, it never lags, it's very fast for browsing and it's light, it's a freaking awesome phone :D
[HTC Incredible S] ila420:
Thanks for the reply, can you use LED Flash with video on IS ?

Xperia Neo is S-OFF with unlocked bootloader. IS isn't.
[HTC Incredible S] alexanderi:
If I were you, I will get SE Xperia Neo instead. HTC is crab with this bootloader locked. You can't do much with this crab.

I regret getting this IS which I am not able to change ROM. Furthermore, you will get bored with this HTC Sense crab. Nothing much.

Also, IS phone signal is very weak. I always have signal drop till no network. I have Moto Milestone compare side by side, MM never has this problem. Same provider, network but this IS is ****.
[HTC Incredible S] vido.ardes:
I really can't beloved the amount of people who are slagging off the IS because it can't be unlocked yet.

DON'T BUY A PHONE EXPECTING THE DEV SCENE TO BE HUGE

The IS is a great phone, and if custom ROM's are the be all and end all for you then its your own fault for not doing research before buying it. The are far, far to many people round here with an expectation that fantastic ROM's and exploits just appear out of thin air, the people that produce them work very hard, and don't owe you anything.

Why don't you do some research and try and help, rather than just twiddling your thumbs and moaning until it happens?

Back on topic, I haven't used the Neo so I can't compare the two two, but it is unlikely to be a huge seller so you probably wont find a huge amount of work for it, even if it is unlocked. I love the IS and have no complaints about the hardware at all, but I must admit the arc is sexy and they do run similar software.

The only thing oi would say is if you want durability with the IS, get a case. The phone is a little fragile against drops without one ;)
[HTC Incredible S] Breadwinka:
The IS is a great phone definitely get a case for it I have an OtterBox for mine works awesome. As l0st.prophet said you should have done the research before buying it I work at Virgin Mobile and I knew before buying it with my 30% discount :P that it couldn't be rooted yet but that time will come. The xperia neo i wont think will have a big following go for the arc or play if u want a sony device.

Otherwise stick with the IS great phone takes amazing pictures and is pretty damn fast specially compared to my Blackberry 9780. Only issue i have is the radio seems week and I don't get as good as a signal with it as I did with my Blackberry 9780.
[HTC Incredible S] mrHD2:
Because some people are only happy when they're complaining, if they could install another ROM they only come on here to ***** about how their wifi don't work, they can't take pictures properly, etc, etc, etc ,etc :rolleyes:
[HTC Incredible S] ila420:
Is this ROMs/Bootloader thing really necessary to have ? I mean the factory ROMS arnt worth it or what, does it have bugs ? Does it Lags ?

SGSII was my first choice but it is very expensive and isnt durable at all plastic body and very thin, i like SLCD on IS much better screen, speed, camera, battery, durability, games, thats all i want on a phone and i guess IS has it all, doesnt matter to me if it is locked on unlocked as it will be my first time with Android i dont have any idea about these things.

Arc is also expensive, IS and Neo are the only mobile phones (i guess) in this price range which are rich in features.
[HTC Incredible S] Mercano:
I will be getting the Neo. Camera and esspecially video is much better and of course HDMI out port is awesome. I dont like capacitive buttons (esspecially if their lightning is crappy).
[HTC Incredible S] Hotdemon:
xperia is way better

neo is just awesome i have it !!!!!!!!:)

my dad has the is its good but neo nails the **** out of it
[HTC Incredible S] shrome99:
I agree with you but consider this - MOST of us want to help, but don't have the skills to actually provide any help. We all are impatiently waiting to get ROOT, flash ROMs and KERNELs, that we forget that it's not easy to find exploits, especially when a company like HTC spent so much money on creating the flag in the first place. (PS - What's the status on the exploit???)

Now, about the phones - the bootloader is the ONLY ONE FEATURE IN NEO, and that doesn't mean squat unless you wanna root, which I'm pretty sure you won't be doing, whereas the IS has a gr8 body, HTC Sense(which beats the crap outta sony's UI), and loads of other stuff. GET THAT FOR SURE !!!!!!!!
[HTC Incredible S] mohamed.qadiqadi:
What about the samsung infuse
[HTC Incredible S] byted:
I would personally stay away from all Sony Xperia series phones. I own an Arc and can't stand the way it handles memory. They all look good spec wise. Unfortunately they don't live up to expectations (at least in my opinion). I have 2 Incredible S and they perform way better. If you don't like SenseUI, you can just use a custom rom.
