Unavailable SD Card issue after (any) Rom Upgrade...Please help!

This is my first post, and I'm usually pretty careful about following instructions. I'm currently running Skyraider's 3.0 RC2, but to my dismay, I am finding that my phone still refuses to recognize my SD Card. Under settings it says it is unavailable, and when connected to PC, it gives an option to mount to disk but doesn't mount upon selecting this.
My phone is rooted with S-Off and 2.15 radio...Did a full wipe of everything before I flashed 3.0 RC2. Shows that my kernel is now King #2, but I have had this issue with many other roms and kernel combinations. I have been unsuccessful in finding a solution when searching the forums, and the only way to regain functionality is to restore a previous backup without any roms installed.
Any help is much appreciate. Thanks!!!
P.S. I've also tried mounting the card in clockworkmod's advanced recovery settings, but this does not change a thing. Internal storage is also currently unavailable. Mount through usb in recovery does work, but this doesn't help when I cannot access my sd card after boot.

I had a similar issue a couple days ago after upgrading from stock 2.1 to SkyRaider 2.5.2.
When I'd go to set my ringtones, the option for the SD card wasn't there. As if it wasn't reading it was in the phone at all. I opened up Astro file manager to see if it could read it and it in fact did. I could see that all the ringtones were still on the card right where they should be and they would play from Astro when I clicked on them. But, the option to actually set them still wasn't there.
I'm not exactly sure what 'fixed' it, but I went in to set my notification tone and suddenly the option to select from the SD card was there. Then, I could then access the card to set ringers as well. I'm sorry I don't have anything more specific. The card just seemed to suddenly decide to let the OS know it was there. I also rebooted the phone a couple times as well as removing the card while the phone was in use and reinserting it. Not sure if any of that helped the situation or not.
I had asked about this in two separate threads and not one person responded, so I'm guessing the issue is rare.
If you don't get anywhere with it, maybe try a different SD card just to see if it shows up.
Good luck.

I've had the same issue but was able to resolve it. Mount the sd card from a laptop or PC. If you can read the card copy the contents onto the PC (I placed mine in a separate folder). Then go into tools and do an error checking. After replacing the SD card back in the phone see if everything is ok. this fixed my SD card. However, I've had the SD card lose its primary disk notation so I had to reformat and then transfer the previous save files on the SD card from my backup an that solved my other issue. Also, some times the SD card speed can cause this issue and it is perfered that you a class 4 or better. I hope this helps.

Well, I took your advice and pulled the sd card only to mount it separately and scan it for errors. None were found. I've also reformatted and restored all the files that were on it. Phone still does not recognize card or internal storage. My phone did, however, recognize another card I had on hand and I believe it may be a compatibility issue between my 8 Gb A-Data brand Micro SD card and 2.2 roms. FYI...It's a class 6, and the one I tried that was recognized was a 6gb sandisk (class 4). I'll look into getting a 16 or 32 gig sandisk in the near future and keep you posted. Thank you guys for your insight.

always 'safely remove hardware' (stop the device, etc.) from your windows machine before unplugging your incredible
if you don't, you end up not being able to see the SD card until you restart your phone

Just reformatted my SD card, checked for errors after unmounting etc... and now it seems to work ok, although one of the music players I normally use doesn't seem to recognise it!!

[Q] CyanogenMod 7 is ruining my SD cards

Now I'm not moaning about CyanogenMod here, I'm just trying to understand how I can fix the issue.
Basically, I had CyanogenMod 7 RC2 on my Desire Z. That was it.
Eventually I saw through ROM Manager that the full release of 7 was out so I downloaded, took a backup, wiped everything and did a fresh install of the new ROM.
It installed fine, but none of my apps that needed root access were getting it.
So I booted into recovery, restored my backup, root was back.
I then installed 7.0 over my RC2. That worked fine, but again root was gone.
At this point, my phone started damaging SD cards.
It suddenly started saying that my 8GB card that came with the phone was damaged. I tried to fix it on the phone, but it just said 'Checking card' and then giving up.
Putting it in an old MP3 player, it is not detected at all.
Putting it in a card reader, the card is unreadable and when I try to format it Windows says the card is 'read only' (this is not due to the reader).
I put a functional 2gb card I had lying around into my Desire Z and it broke it in the exact same way.
My question to you guys is - what could be causing this and how do I fix it because I have a 16gb card coming and I'm obviously cautious of putting it in the phone.
Also, how would I go about flashing the new Cyanogenmod 7.02 ROM if my phone keeps breaking SD cards I put into it?

This error can be because when ever you install a CyanogenMod ROM over another, It leaves files your new ROM think is useful such as data that the new ROM doesn't support. It is damaging your SD Card because it keeps attempting to fix the error but is making it worst by trying to remove system files. Your best bet is to try another ROM and see if it does the same thing and report it to CyanogenMod Developer Team if it only does this to CyanogenMod ROMs otherwise it would be just a virus on your SD Card feeding off of personal data. If it is only CyanogenMod ROMs, we will adress this issue ASAP. Hope I helped

Thank you VS4, you are indeed helpful
I've since heard some people have managed to fix their SD cards by formatting them in ClockworkMod but I can't even mount it first in order to do this! Is my card truly dead?
Also, do you think the reason that CM7.0 had no root (even when it was a clean install) was due to me not 'fixing permissions'?
Thanks

Just a note to say that I've managed to fix it!
Despite being unable to 'mount sdcard' in clockworkmod, I found I was able to activate USB Storage and through this I was able to format the card (Windows 7 was previously saying that the same card was 'read only' in a multitude of card readers).
I hope this helps any poor chap with the same problem.

I had this exact same problem, munched 2 of my 8GB cards, and had a 16 on the way. I somehow fixed it before the 16 came and I've never had the issue since, glad to see an explanation of it.

Thanks, nofixio!
I had the same problem on my Samsung Fascinate with CM7. It ate my 16GB SD card to the point where the phone wouldn't recognize it, CWM wouldn't mount it, and it wouldn't show up on my computer in multiple SD readers.
I wasn't quite clear what you were suggesting when you said you were able to "activate USB Storage." I thought maybe you meant within CWM. That didn't work for me, but I was able to boot the phone up with the problem SD card in it and turn on USB storage as normal. Suddenly my computer could not only see the SD card, it could see all the files that were on it before it died! I backed everything up, formatted the card in Windows, and everything's good now. Thanks for the tip!

I'm not sure why you would ask this in such an old thread but... Try just plugging it in to your computer maybe? What ROM are you on?

im running cm7 ... it wont read from computer. i tried several micro sd card readers. it just tells me it cant format. its just like what was mentioned before.

Weird, I've never had any problems with Cyanogen 7 roms. I've flashed one over another and had no issues at all, Mayb because I use SuperWipe before hand? Or maybe its a certain sd card issue???

Running Desire Z and Andromadus Beta 11 I had similar problem after I had applied remote wipe from Exchange (wanted to see if it works). Remote wipe worked: it destroyed contents of SD card and erased phone back to factory settings. After wipe mounting SD card failed and Andromadus seemed to be unable to format the card.
Solution: Booted phone to Clockwork recovery and applied advanced -> Partition SD Card.
Posted this on this thread since it came first when searching solution.

Go into Recovery (Clockwork), go to mounts and storage, then scroll down and it should say mount USB storage.

most of app won't read SDCard

Hi...
This is my first post here.
I have a problem with my SD Card.
My SDCard: 32GB microSDHC, some application like music player and gallery sometimes can't read file on my ext sd card (but my file manager can do it flawlessly)
Furthermore, sometimes it shows PREPARING SD CARD on top of the screen, although I don't even do anything. I tried to re-mount it again. But the problem still sometime occurs.
This problem started happening when I changed my stock rom to Ressurection Remix, I thought this problem occurred because of the ROM. so I change it to AOSP. But still... the problem still existed. So then, I changed it back to my stock ROM (with restore option in CWM)
But yeah... Nothing happen.
Any idea?
P.S.: Sorry for my bad english.

extSdCard/sdcard 1 issues
I have a Note II N1907 (ATT) running Liquid Smooth with a SanDisk microSD ultra 32gb. I have been trying to figure this issue out since I bought this phone 2 months ago. I screwed up the original card that I transferred from my old phone some how by trying different things to make the phone recognize it. It worked fine in my HTC Vivid. I have root and am able to use root options to try to access this card of installation, but the best I have been able to do is use it for storage. And I have to manually move things to the card, because most apps do not acknowledge that it is there (can't see it). TWRP recovery can see it after I did my first ROM Flash, but I have to use internal memory for my first ROM Flash, because recovery mode was unable to mount extSdCard.
Is there a kernel I can flash to remedy this. I am no developer, but I think the problem is that the internal memory is also SD in type. I have noticed that internal memory shows up as SDcard0 (zero) and the after market sd card is sdcard1. Maybe the phone automatically defaults to the first sdcard and ignores the other (because it is only designed to have one sd card).
I am sure others have hard this problem with this phone. Thank you for any help you can offer..

As soon as I saw your reply I scanned for the words "Sandisk Ultra" and then I knew this was your issue.
I had a lot of SD card corruption with this brand and searching a lot on the web I found many stories of people having the same issues as I did.
My 32Gb Sandisk Ultra was the cause of many of my problems. 2 months on with a Lexar 32Gb, no problems (touch wood)

[Q] MicroSD woes

Hey there.
So, I have this wonderful HTC M8. Love it. It's great. Except for my experiences with microSD cards. Basically, I bought a $30 samsung µSD, 64gb, great, wonderful, everything. Something killed it. It lost its formatting every time I mounted it in either Android or Mac OS. So, I returned it, bought a different brand (unbranded, 64gb, $10). This card works great... as long as I don't write data to it from anything except Android. I'm rooted/S-off, so I was able to mount it as RW with ES File Explorer, and yeah. But whenever I copy files to its root directory from my Mac, Android proudly declares that the card is damaged and needs to be reformatted. At this point, I'm going to assume that this isn't a problem with my card, and more a problem with how Android handles things (or how I'm writing files). What the hell is going on, and how can I fix it?
Thanks!

I have problems too with my microSD. I backup to my mSD, whether with TWRP or CWM, and it always fails to restore. I've re-formatted it and I've had the same problem with the dialogue "Damaged .... needs to be reformatted."
Did you ever figure out the problem?

Don't compress the backup

I have no problems writing to, backing up to SD Card from PC or phone. Not sure while you're experiencing your issue but with root and a root file manager, all should be fine.

I haven't been compressing my backups. I actually tried it both ways once. I keep getting "Failed...can't verify md5". Something like that.

Yeah, I can backup to. I just can't do a restore from the mSD. It's weird. Maybe because I formatted it on a Mac, but it was done with MSDOS (FAT). I'll try formatting it on a PC and see if that works.

Format it with your phone.

I'm having different SD card issues, Zoe won't work with my sd card, its a sandisk ultra 64gb class 10 UHS-1 and it says I need a higher class card with at this moment is impossible.
I formatted mine with my phone to try resolve it but made it worse, it formatted it to HTFS/NTFS and when i checked what the storage was like on it, it only read that it was a 10gb card, but my computer picked it up as a 64gb card, so try not to use the phone to format it. I went back to it being fat32 with an app from the playstore, can't find any apps to format it as exFAT though.
Other than that mine is fine.

Writing to sd card restrictions were placed by Google in KitKat 4.4+ versions as a part of 'system enhancements'. I have rooted my M8 and the following three things worked for me:
1. Buy San Disk or another reputed brand card (authentic, fake/generic one gave me the same error message). Generic one are flimsy and often will give you an error message that card was unmounted unexpectedly.
2. Removing write-off protection, see the process at: http://forum.xda-developers.com/showthread.php?t=2701816
3. If above two methods still give you the same issue, try formatting the card in fat32 format. It will limit the each file size to 2GB but at least will make the card usable (use this only after trying item#1 & 2).
Good luck.

[Q] Writing to SD through a computer Issues

Hello everyone,
I currently have a 10.5 stock rom rooted with some debloating not much taken out. I've been having a problem with my 64 GB SD card to the point where it is virtually unusable. When I save things to the SD card, some strange things begins to happen. After a while the files that were added would simply disappear almost as if they have never been there to begin with. (This includes folders that were made within the SD Card) Or they would work for a while and just simply stop working. When I add music (MP3 or which ever format) the sound would be speed up making it unpleasant to listen to. This happens if I add new files to the SD card from the tablet or directly to the SD card with a computer through a USB cable. I am wondering, has anyone else experienced these issues? Is it the card itself or simply the tablet? I have done some research and I have not found anyone else having this issue in this website or elsewhere. Can you please help me?
Thanks ahead of time!

I am surprised you have not found any related posts as there are many about the SD slot on the Tab S. My 10.5 has similar problems, I have a 32 Gig card that at times will just not be readable by the tablet. I keep all my music on there and at least once a week when I fire up my music player it says it can't play the file. For me a reboot of the tablet fixes it for a few days but it is still an annoying issue. I am hoping the Lollipop update will help fix some of these SD card slot issue. I tried formatting my card in the tablet and that did seem to help some but I still have intermittent problems with the SD slot on my Tab S 10.5. Oh and I tried the card in other tablets and my phone and it never has an issue so I don't think it is the card.

I have not experienced issues with the sound speeding up, and are you saying the files actually are no longer on the card even it you view the card on your PC? Are you always connected to the PC with the card in the tablet? I assume if you pull the card in read it on your PC not in the tablet that all your data is still there?

Yeah I'm surprised too maybe it's our tablets? To tell you the truth the files just the files would simply dissappear after a while. Almost as if it never existed to begin with. I have some files there sure, but not nearly what I want. What makes it even stranger if I move a file from the tab to the SD card it will stop working. If I move it back to the tab itself it still longer works. It's the strangest thing I've seen.
