I have the SanDisk 64Gb ExtSDCard in my phone and do not have issue with it. I love all the space it gives me for backups in Safe Strap. Where are you getting this information that the card is mounted as "Read Only", Dwillian? I have never had issue like this. How do you know that you have a R only card? From Settings/Storage or in a file manager, which one? Settings/Storage tells me that I have 59.12Gb and 39.1Gb available. Nothing about Read Only or filesystem. cm11 File Manager shows no Permissions in Properties for this card, however, looking at the two cards from the root folder, "/" shows each card with the permissions assigned to it as they are links from this location. Under /storage where the actual devices are listed, the permissions are R/W for both except for the third permission set, "world" which is "execute only" as it should be to "outsiders". You are either the owner (first permission set wrx) or are in the group for this device (second permission set rwx) Will show screenshot, attached.

/storage/sdcard0 (internal) - drwxrwx--x

/storage/sdcard1 (external) - drwxrwx--x

Actually, by using cm11 File Manager, you can change permissions when the padlock icon, top right side, is "unlocked". Tap to change it's status. By holding finger on /system/sdcard1 you bring up options. Choose Permissions. Then tap the Permissions tab. Here you can see and change the current permissions of this card. Screenshot #3 attached. As long as padlock icon is unlocked, you can change the permissions on this card by checking and unchecking the boxes. Mine are properly set. Check screenshot #3.

They are the same. Use cm11 File Manger and what does your card show? Where are you getting this "Read Only" status from? Does your cm11 file manager show the same when you navigate to /storage?

I did a double check by plugging the phone in USB to a Windows computer. Both cards are formatted as FAT32 and both cards are accessible, read, write. Screenshot #2 attached.

To help you understand the Android/Linux file system permissions, view this link and then scroll down to the blue diagram. It shows the first character indicates if a regular file, link or what it is. next 3 characters are for the file owner. Next 3 characters are for "group" assigned to this file or space, last 3 characters are for "world" or, "anyone else". If the file belongs to you, the first 3 characters, rwx applies to you. If it is a root or system file, then the next 3 characters apply to you, rwx. If not your file and you are not in the group, then the last 3 characters apply to you, --x, meaning you can view the contents but cannot do anything with them.

So, check in file manager and what do you have for /storage/sdcard0 and sdcard1?
[Motorola Droid RAZR] Dwillian:
I get the error message when I try to use the CM File Manager to move files (e.g., CM nightlies) from internal storage (sdcard0) to the new micro SDXC card (sdcard1).

At this moment I am reformatting the card to exFAT on my Windows 8.1 laptop (using the microSD to SD adapter that came with the 64GB chip), so I can't check the permissions. It's taking a long time to complete the format (probably because I unchecked Quick Format).

Once the reformat completes I will put the card in my phone and report back on the permissions. I have checked the permissions previously. I didn't write them down, but I'm pretty sure both internal memory and external SD card showed same permissions.

Usually right after a format I can move files onto the 64gb card, but after awhile I start getting the error. I think this usually starts after I reboot. I will see if that happens again.
[Motorola Droid RAZR] Ohmster:
FAT32 has no inherent file permissions associated with it. That is why it is never used for computer OS drives anymore. Stronger file systems such as Linux Ext3 or Ext4 or Microsoft NTFS do have permissions set right on the drive and in the file system. FAT32 was used in Win95 because it is a 32 bit file system and gave us long file names. And it is a "universal" file system that can be read and written to under many different operating systems. Microsoft quickly replaced FAT32 with NTFS due to security issues associated with FAT32 for Windows file systems.

Note of Interest:

Many people will buy an external USB hard drive to use with Windows Backup and it will work great for this job. However, if the drive is and probably comes with FAT32, you will NOT be able to backup a disk image. To change this and be able to create a disk image in Windows Backup, right click this drive in "Computer" and format as NTFS. After that, your backup WILL create a system image. This image is necessary to completely restore the hard disk as it was at the time of the backup.

Do not format your SDCard as NTFS!

Format the card as FAT32 in your USB holder in Windows. You cannot "Quick Format" one file system to another since they are totally different. Quick Format is only used to wipe a filesystem clean, it cannot "build a new file system", for that, you must use Full Format. Put it back into your phone and see how it works. Check permissions in File Manager. Check again after reboot. If necessary, unlock the padlock to give root access and long tap /storage/sdcard1, Properties, Permission Tab, and match the permissions shown in the screenshot. That should be all. Report your results. Good luck. ;)
[Motorola Droid RAZR] Dwillian:
I mistyped in my original post. I meant to say that I am reformatting to exFAT (original post subsequently updated). I've read that the latest versions of CM 11 now support exFAT and NTFS. I hope that's true or I'm going to need to reformat the SDXC card again.
[Motorola Droid RAZR] Ohmster:
Really? I am very interested to see your results. Please post them. Good luck, Dwillian. :D
[Motorola Droid RAZR] Dwillian:
The reformat to exFAT finally completed after several hours. I don't really know how long it took since I finally went to bed.

I turned off my phone, inserted the newly reformatted sdcard, and then turned on my phone. I checked the permissions on both sdcard0 and sdcard1. They both have the same permissions as you showed in your 3rd screenshot (i.e., rwxrwx--x). Here are screenshots from CM11 file manager:

Sdcard0:

Sdcard1:

I then successfully copied my CM11 nightlies and PA GApps zip files from sdcard0 to sdcard1.

I'm now going to reboot to see if anything changes. Fingers crossed :)

Update1: I am still able to write to sdcard1 after the reboot :) I'm now going to boot into recovery to see if anything changes.

Update2: I am still able to read and write to the sdcard after booting into recovery, wiping cache and dalvik cache, and rebooting :) Now I am going to copy files from my pc to sdcard using sdcard adapter in my laptop.

Update3: I powered down my phone, removed sdcard, placed sdcard in adapter and inserted into my laptop. I then copied over all the files that I wanted from my original 16GB sdcard to the new 64GB sdcard. I then reinserted the sdcard into my phone and powered up. Everything still works fine.

I'm going to use it this way for a day or so to make sure the read-write access problem does not reappear. If the problem does not reappear then I think the reformat to exFAT has worked and the trick was to NOTdo a quick format. Somewhere along the way I did use one of the free partition tools to delete and repartition the card. As I recall there may have originally been two partitions (one very small partition and one very large partition), so repartitioning to one partition that spans the entire sdcard may also have been a factor. I will provide a final update in a day or so.

Thanks for the help.

[MENTION=5362796]Dwillian[/MENTION], when you plug your phone into your computer through USB, does your new card appear as EXT4 or as FAT32? I thought I read somewhere that the phone emulates FAT32 no matter what the actual formatting is in order to ensure maximum compatibility across platforms.

[Motorola Droid RAZR] Dwillian:
Both my internal and external SD cards appear as "Generic hierarchical" file system when mounted as a media device (MTP).

Once I'm done syncing my iTunes music library (which may take awhile since it's about 45GB) I will try the other mount options (i.e., PTP and UMS) to see if it appears any differently.

Update: I mounted my phone using USB mass storage mode (UMS). My internal memory now shows as FAT32 file system and my external SDXC card shows as exFAT file system.
[Motorola Droid RAZR] brkahughes:
I seem to remember they were referring to "mass storage mode".

This applies to most of the ROMs on here, (but, since I'm using CM11 as my DD now, I thought it'd be appropriate to ask here) is there a reason why the status bar lags when you slide it down when there's alot of notifications and running a browser (or any other app) in the background? Optimization issue? Cause on my Epic 4G Touch (Running CM11 nightlies) it's consistently smooth with many notifications going on and with apps open in the background.

[MENTION=6010326]VagueDeity[/MENTION] - Maybe better Exynos chipset support for KK? All OMAP4 ports are still a WIP, but they keep getting better! We know there are still memory bottleneck issues (freezes, black screen on wake up) under certain circumstances.

[MENTION=1807728]brkahughes[/MENTION] Well, Samsung never released the source code for the Epic 4G Touch & some things will never be fixed ie: low speaker volume (CM10+) & finicky data on CM11. I just read that TI dropped out of the mobile SoC market, so now it's more clear to me. :]
[Motorola Droid RAZR] Ohmster:
If you are good to go now, terrific. I searched all my saved files for different issues. The one link I used to fix my EXTSDCard write permission is here:

[Fix][N9005][ExtSdCard Write Issue][Kitkat 4.4.2][NA6] - Rooted

Might be a day late and a dollar short, but it is here to help others with issues writing to their external SD cards.
[Motorola Droid RAZR] Dwillian:
Well....the card started acting up with random dismounts and somehow had it's permissions changed back to read only. I tried reformatting to FAT32, but had similar problems.

I read that this can be symptomatic of a failing card. I finally gave up and returned the card as defective. I have a Patriot microSDXC 64 GB class 10 on order now. Hopefully that one will work. If not I fear my phone may be incompatible with sdxc cards (to test that I may try a 32 GB microSDHC card), or it's developing a hardware problem.

Thanks for the help.
[Motorola Droid RAZR] Ohmster:
Hmmm, perhaps it is a bad card. Although I am trying not to install too many apps, this one does not run or use memory if you are not using it and it is not a large app. But it will give you lot's of information about your card and it's performance. Maybe you should try it. Actually, I have a few of them, check them out. #2 allows writing to your ExtSDCard.

A1 SD Bench

SDFix: KitKat Writable MicroSD

These are the two apps I have installed, but there are so many useful SD card apps that you really should browse them yourself to see if you think you need or could benefit by any of them.

[Motorola Droid RAZR] brkahughes:
I cheaped out and ordered a 64 gig from eBay, picked one for less than the Sandisk, and wasted my money! First few days, life was good; then a couple of things that should have been on the card weren't there. Soon entire directories started disappearing! I tried to use an SD format utility on my PC and it stalled part way through, now the card isn't even recognized as storage under Windows or Linux, and no low-level tools can touch it.

All of which is symptomatic of an SD card going bad, but it all took place in about a week! The "money back" guarantee required me to pay return shipping, to China; not worth the buck or two I would net against what I spent.

Moral: shop wisely and don't always grab the best price out there. (Like I didn't already know better...) [emoji15]

Yeah, I am always leery about buying things online, but I always get tempted by the low prices.

Fortunately (surprisingly) the e-bay dealer I bought my card from (in Texas) paid return shipping and gave me a full refund about 2 days after I mailed the card back. The next card is coming from Costco, so it costs a bit more, but they do have an excellent return policy.
[Motorola Droid RAZR] crackerjack1957:
That's the 1 I'm using, works well with cm11 but if I boot into stock jb its not recognized.

[Motorola Droid RAZR] Dwillian:
I'm guessing that you left the card formatted as exFAT. I think the stock ROM only supports FAT32, but CM has added support for exFAT (and possibly NTFS).
[Motorola Droid RAZR] Ohmster:
Brian, I am really sorry to hear that. But for what it is worth, perhaps some of my past experience will help you in the future. Yes, I am always buying stuff online, simply because it is cheaper or it is the only place I can find it. One thing I learned is that Amazon has very good prices, they sell their own products as well as third party products. More than once I got a bad product from Amazon. One was not even their product. I needed a Samsung DVD player, the kind that plays any disc, even mp3 disks as well as data discs with avi movie files on them. When I used to burn movies to a DVD, I usually get them online as 700Mb HQ avi files. Then I had to convert them to true DVD format or use DVDShrink and it was a time consuming process that only yielded one movie per disc. These new "play anything" DVD players are upscaling to output to 1080p and play anything. They cost about $65, I had one, my best friend had one, and now mom wanted one. I bought them from Amazon.

This time Amazon was out of them but had a used one from a third party for $20. I bought it. The vendor did not send a tracking number or even acknowledge the sale and after a couple of days, I called Amazon. Yes they have a phone number, you can call them 24/7 and there is no long wait time. The man said to give him a chance to check with the seller and he would help me. He sent the package and when I opened it and plugged it in, it would not recognize any discs inserted, all but maybe 1 out of 20. Being an electronic tech and seeing and fixing this problem many times, the laser pickup ass'y was bad and would cost over $100 for the part. Amazon immediately refunded my money and when I asked about shipping the product back, he told me to throw it out. I had another incident with a defective product purchased through Amazon and I was refunded immediately from Amazon, they never make you "go to China for a refund". So for what it is worth, stick with a known good vendor.

Two that I personally can speak up for and recommend because I have gotten immediate refunds or replacements are Newegg and Amazon. Yes, I know, a day late and a dollar short, but if this lesson sinks in your brain, you will never have this problem again. :good:
[Motorola Droid RAZR] Dwillian:
The card (Patriot 64GB microSDXC class 10) is working great for me too.

Before first use I booted back to stock ROM, inserted new card, received message that card was blank or had unrecognized file system, let phone reformat card (to FAT32), rebooted to CM11 and everything seems to be working great.

Not sure if my original 64GB SanDisk was defective, or if the problem was that it was a UHS-I card versus a class 10 card (I thought that UHS-I was backward compatible with class10, but maybe not).
[Motorola Droid RAZR] crackerjack1957:
Thanks for info, will have to remember that.

Good see your new card is working!

Could flashing cm have changed my Mac Addy ? They have Mac filtering enabled at work and I can't Conect.
[Motorola Droid RAZR] Ohmster:
[MENTION=3865478]iamteachme[/MENTION], I am not quite sure of the question. What is it you are trying to do or cannot do anymore? You want to get on WiFi at work and you can no longer connect to the network? More involved than this? VPN? What do you want to do, were you able to do it before? Details, please! :cool:

Oh, you mean your WiFi MAC Address has changed or you want to change it? Well, first of all, if your company allows WiFi connections based on the device's WiFi MAC address, you should turn on WiFi and go to the IT department or person, and have them add you to the IP pool for WiFi access. Barring that, there are procedures and apps that can do this on a rooted phone, one such app is here: Wireless Mac Address Changer. This can change your WiFi MAC Address to let you in. But really, w/out knowing what you want to do, answering this question is impossible w/out more information. :rolleyes:
[Motorola Droid RAZR] iamteachme:
OK sorry I has Mac Addy added at work. All was well flashed cm now Mac Addy has changed. Wanna change it back.

[Motorola Droid RAZR] Ohmster:
Holy crap! I don't mind sitting at the help desk, that's what this thread is for. But I will tell you, this is a very difficult and tricky post for anyone to answer. Not sure what it is exactly that you want to do. I believe that you had your phone setup to use at work or home WiFi and since you flashed a rom, the WiFi MAC address has changed. Yes?

You know, having a different WiFi MAC address than you had before is no big deal at all. Normally, all you need is your WiFi network password to connect once to your home or office WiFi network, once authorized with the proper password, you are good to go, connected. The password will be remembered so next time you connect, it will do this all by itself.

In some network setups, the router itself will allow access to devices who's WiFi MAC address has been previously recorded and access is then granted to those devices. On a home router, no big deal. Open the router admin page in a browser and allow the new WiFi MAC access. At work, you can do the same thing by requesting it at the IT Department/Person. If for whatever reason, this is not something you can do, then you must restore the previous WiFi MAC address and this is dependent upon a very special folder and files that you have on the phone. This folder is so important that our developer, Stargo advised me to backup this folder immediately upon getting my replacement phone. All of the important IDs for the phone are stored here.

The necessary folder is this one: /pds

The WiFi file is this one: /pds/wifi/nvs_map.bin

Never mind them right now. Just check in File Manager that you actually have this folder and the files/folders inside of it. [MENTION=5849464]mikeoswego[/MENTION] and our own beloved [MENTION=3313632]ChungHung.Chen[/MENTION] has made a post about how to fix this here:

Post #5330

First perform the "wifical.sh" procedure. If this does not work, I have attached my own nvs_map.bin file that you can carefully edit in the event that your /pds folder is missing or damaged. For that links are provided for the file editor and instructions. Before you go

that far

, do the wifical and let us know what your situation is, i.e.: do you have the /pds folder and it's contents.

I have sent out for The Cavalry, hopefully they will come soon or we will get this issue resolved. Please be kind and tap the Thanks button for those that actually do help you. ;)

Good luck! :good:

EDIT:

If your /pds folder is gone or damaged, this will get complicated. You do the wifical trick mentioned in Post #5330 in Terminal Emulator for Android and if that does not work, we try more difficult stuff. I put up a Help Req in the main thread so if need be, we will get additional help. :fingers-crossed:

HEY! Before you flashed cm11 and your WiFi MAC changed, what rom were you running on the phone before that which actually would connect nicely with the WiFi at work? Stock or something else?
[Motorola Droid RAZR] iamteachme:
Yeah they use mac filtering at work and I T are kinda pissy about changing things. WiFi Mac changer works but must be done on every reboot. Thanks for the info above I'll read up. I'm about 3 weeks from an lg g2 so I may just wait and give them that Mac Addy when I get it.
[Motorola Droid RAZR] brkahughes:
Did you use the "hard" method the developer mentioned? That "should" change the MAC in the /pds partition if I'm understanding it correctly. If not, editing the map binary directly may be the only permanent fix. I would recommend DroidEdit Free for any file editing on phone. And, yes, corrupting/losing the device WiFi MAC address when flashing ROMs is a known danger, especially if you flash a custom ROM to stock.

Okay, so if we cannot fix this soon, you will be alright anyway, but, we lose a valuable member to the Razr community. :(

...just kidding, get what is good for you, bra. My Razr just lost the LTE chip. I could have gotten a serious upgrade like the Galaxy I always wanted. But, that would cost more money to purchase than I am comfortable with right now, and in a strange way, I made a LOT of very good friends in the CDMA ROM thread and would miss them, a LOT, if I changed. I got my Razr working very well now. Learned a lot of new tricks, things to avoid, things to do, and it is quite snappy and a very good smartphone now. Over a month ago, I was ready to throw this thing in the ocean. It would take 5-10 minutes do to *anything* like get GPS directions or even make a phone call! I redid the phone from scratch and followed all the advice given to me in the main thread. This time I got it right and have nothing to complain about. I will take this new advice and what I learned with me when I do finally upgrade my phone. ;)

Seriously, do you remember, have a screenshot, or have the original WiFi MAC address that you are now missing? I attached a screenshot of mine for you to see. I will give you something easy to do, I just did it myself to make sure it would work, and for me, it did exactly that. I "restored" my original WiFi MAC address and then verified it with screenshot #1 I sent you. Screenshot #2 shows the process working. Look at the screenshot and see how simple it is to use, then try it, okay? This is easy, you can do this, bra! :D
