Suddenly, my 32gb Sandisk microsd is not reading on either my phone or the card reader of my PC. I was doing a nandroid in TWRP. It finished, but, after reboot...nada. It's like the card isn't there. Is there anything I can do? I have a lot of pics on the card I definitely want. The other stuff, not such a big deal.
From what I've been able to search and find, I don't think there is a software solution here. Any weird tricks I can try? Thank you.

Where you trying to parttion the sd card using CWM recovery or were you just making a nandroid backup ? If you want to partition the sd card its better to use a software on pc than using CWM recovey since CWM is known to have bugs in the past.
I would advise you to download a partitioning software called minitool (free version available) from the internet and install it on the pc.
Then insert the sd card in the card reader and plug it to the pc. Now run minitool and if it detects your sd card repartition and format it.
If it doesn't then it is possible that the sd card is damaged. When you buy a new sd card try to partition it with minitool because it is far more reliable.:good:

Hi there everyone, I just picked up my Transformer today, and while Im not new to the whole flashing business (done it lots on my Galaxy S) I cant seem to get this working on the tablet. Ive managed to get it rooted and CWM loaded, but every time I try to flash a zip from my sd card its lot letting me mount the sd card.
Was hoping someone would be able to help me out
CWM only read files from the Removable micro sd card and not internal sd card.
Also the removable micro sd need to be in a fat32 format

Are certain microSD cards not compatible? I've currently got one in FAT32 format and it cannot read that either.
Some people have reported problems with using a MicroSD when formatted as Fat32 through windows. Try using an SD card formatting tool. Apparently when formatting an SD Card through windows it doesn't format it correctly.
Also some people say they had to try a few card before one could be read.
Hello,
My Desire S is running on rom BlindMIUI_v2.5.25 which I loaded June 5th of this month. Suddenly since 3 days back it is saying "Damaged SD card storage" and also saying "Format USB storage, erasing all files stored there, action cannot be reversed"
Please advise should I format SD card? Will this solve the problem. If I format then I will try to save files and then will do it and restore the file again.
What happen is that if I reboot is for few time the SD card comes again and for no reason I disappear without any notice.
Please help me if there is any solution.

Looks like It's corrupted. A format should fix it. Connect it to your computer via a memory card reader or mount it in recovery and backup everything to your computer if possible. Then do a full format of the card (uncheck quick format in Windows). After that use the 'format sdcard' option in recovery and then copy the backed up data to the phone.

Hello sashank,
Thanks for so prompt response. See I have just inserted another SD card and now phone does not get any SD card. It says "SD card is not available". From this it seems to me it is rom problem not the SD card. Am I correct? Should I change the rom and go for a newer version which is MIUI.us-2.6.8 or just a format will do?
Please advise.

Hello darkion,
The phone is giving the option to format it. Should I do the format through phone or is there any other way to do it. Please advise me in details.
Would appreciate your help.
If your phone is giving an option to format it then use it. I find it strange that it didn't detect the other SD card too, but in any case if it's asking you to format it instead of just not detecting it then it doesn't seem like an issue with the card slot. So format it in the phone and see how it goes. Alternatively, go into recovery-wipe and format-format sdcard. I always use this for formatting my card as it works better then formatting it in the ROM itself, especially when my card gets corrupted.

You should not forget to simply clean your sd-card and the slot in your device a little bit. This might be an easy solution, you should at least try it.
Or maybe you've already done .. ?

Hello sashank,
What I did is I formatted it in the PC so as in recovery as you said in the earlier response. The phone give the option but it does not work so I could not formatted it through phone.
It seems like working now. Phone shows there is SD card and through file explorer I can go to SD cards file. But only thing is that when I go to SD card files through file explorer, it take few seconds to retrieve the SD card files which never happened before.
Thanks for all your help.
Ok, when you format it in the PC, if you're using Windows, choose a cluster size of 32k in the format window. It gives a better read and write speed, especially read speed. So the SD card shouldn't take that long to show files. In general you'll see the card is giving faster speeds, both on the phone and when transferring files from the computer.
Also there's another way to increase the read speed of the SD card in the phone, which is by setting a higher read ahead speed. If you want to know more you can search about it, but otherwise just install this app SD Speed Increase, set your read ahead speed to 2048kB and tick 'set on every boot'. You shouldn't feel any SD lags after this. This speed increase is only on the phone though, won't reflect if you're transferring files from a computer. You need to be rooted for this to work.
Hi ,
Im usigng CM9 in my explorer. Today i tried to partion SD card via mounting it from recovery and partitioned using minitool artitions oftware after that im unable to see SD in my explorer. although it was partitioned also when i try to insert memory card it says SD card is safe is remove everytime i insert SD card , before partioning it was wokring fine...
Well get to card reader and repartiotion it again, probably you didn't make both partitions primary or something else, maybe it's some fail because you made it from recover...... There are a lot of maybe's, sure thing is to partition it with card reader.

I used read reader now and partitioned memory card again , one 6.4gb fat32 primary and other 1gb primary ext4. now when i insert memory card in mobile it still say sd card is safe to remove....
this card was working fine before as i make partition before but this time im getting this problem
When I plugged my sd card to my memory card reader, It wants me to reformat the card to be able to use it. I said ok that's easy because I've tried it before but then It says windows unsuccessfully format the sd card. I've tried a lot of things like using the command prompt, device manager etc but to NO avail, I still cannot reformat it. Now I cannot make partitions for my apps. PLease do help me.. thanks.
HOW CAN I REFORMAT MY SD CARD?
Most likely, you might have write protection on. You can disable it by getting the Micro SD card adapter and sliding it back to off.

Or try formating it on android itself.
For me also windows couldnt format but android did it..

Ditto what sanjay said.
I bought a new sd card for my dinc. I tried to format it but Windows said it could not format. I was able to use the card anyway as I later learned that the card came pre-formatted.
Hi All,
I have a problem with my SD card. (Sandisk 32gb).
The SD card was used in an android phone and formatted as internal storage, which I'm guessing encrypts the data as well.
In order to use another card in the phone, the card was removed and 'forgotten' in the phone (yeah... not very smart...)
I have already come to terms with the fact that my data is now lost forever, since the key for the encrypted data was deleted. I'm trying to reformat the card so I can use it again.
The problem: I can't format the SD card.
I've tried the following solutions, which did not work:
- Try to format the SD card using the phone. -> this gives an error message.
- Try to format the SD card using a computer:
The card doesn't show up in explorer, so I worked around using EaseUS partition master, when I try to wipe the disk, or when I try to delete partitions, I get an error. When I do a surface check, the program crashes.
- Try to clear the SD card using DiskPart, which gives a 'Data Error (cyclic redundancy check)' error.
What else could I try?
If you format your SD card directly from a PC, your choices are NTFS (which an Android device can't read) or FAT32 (inefficient & doesn't support files greater than 4G).
The best way to format an SD card is using the official SD Card Formatter from the SD Association:
https://www.sdcard.org/downloads/formatter_4/
This will format the card as exFAT which is supported by Android, while maximizing storage space.. Download, install, format, enjoy!

Thank you EEngineer for reacting so quickly!
I've tried the SD card formatter you recommended. However, although the card is recognised by my computer, it is not assigned a drive letter for some reason (I've tried to give it one using disk management, without success (it basically gives a cyclic redundancy check error every time I try to do anything with it)) and it doesn't show up in explorer. It follows that my card is not recognised by the formatting program, and so I can't get it to work.
My hypothesis is that the phone has formatted the card so that it cannot be read by my computer anymore and then threw away the key, so that it cannot be read by anything anymore. (which really sucks, because there's probably nothing wrong with the hardware of the card, and yet I'm going to have to throw it away if I can't get it to work)
Any other ideas?

Have you tried fdisk command?
There has been some time in between posts. Sorry for that. I really appreciate you helping me out.
I'm quite keen to get this issue resolved, since if I don't I've just wasted some money...

Yes, I have already tried fdisk. It resulted in the same error described above.

Try SD formatter for Windows, it has some tools to diagnose/repair SD cards.
