Can't access storage card

I've recently ran into a problem where i cannot access my memory card on my dash.
I was playing around with my friends phone and wanted to see if i could send him some mp3's but bluetooth didn't work, so i decided to take out my microsd card out of my dash and put it in his phone.
I couldn't find the storage space on his phone so i asked him to look for it. He found it and the phone couldn't read the card so it prompted him to format and before i could say no, he clicked yes.
I put the card back into my dash and tried to boot up but failed, got stuck on the startup screen. Im guessing its because i have so many startup programs stored on my storage card. So i performed a hard reset and it no longer got stuck at the startup screen.
Now the problem is that when i go to my file explorer, it won't detect my microsd card. Is this caused by the hard reset or perhaps because my friend decided to format my memory card on his phone?
Any help would be appreciated as to how to save my memory card. Maybe i just need to go buy a new card, just thought I would ask on the forum before i did that.

So if it doesnt detect it, no option to format it, right?
I would but it in a pc and see if it detects it. If it does, format it to Fat or Fat32 and put it back in your phone and see what happens.

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] SD Card Destroyed??

I picked up my phone looking to download a new ROM to it but then found that my ES File Explorer (given root permissions) was not able to view my external SD card via the mnt folder. At the same time, I was trying to back up my apps and such via Titanium Backup but it said that it couldn't backup anything because my card was full (it's default save location is my external card). It just said "Empty". I went to check my Settings to see if my card was somehow unmounted, but nope, it said it was still there. Even said that I had 11.27 GBs left out of 29 GB or whatever and gave me the usual options to Unmount and such. I pulled off my battery cover and the card was still there, so I assumed that the Android system might just need to sit for a while and cool off while off. Then I turned it back on to find that ES was still not able to view the contents of externalSDcard. So I went to my Root Browser and it too said that no files were there. I then went into my Settings and now it just says "Insert SD card".
I've had this happen before on other Android phones so I did what I normally do and hook it to my PC and reformat it. Windows found the device when I attached it via a SD card reader (the big fat kind like in your standard camera), it didn't want to format it. Windows brought up the prompt and said that it only could format 1GB so I knew Windows wouldn't be able to recognize it. I even tried formatting it via Command Prompt and typing "Format G:" and it too said there was only 1024MB to be formatted then went through trying to format and then said it failed.
I then tried pulling up Ubuntu's Disk Utility to format it. At first, Ubuntu wouldn't even correctly identify the device! Then I got the Disk Utility to recognize it and it couldn't even recognize how many GB/MB were originally on the card! Trying to format just brought up a message telling me that it couldn't do anything.
I had this happen a few times with my HTC Evo 4G OG but was able to format the card and put it back into my phone and have it work. Of course, the last time with my old 16GB card ended with it being destroyed much like this.
Please tell me that I can do something to fix this. Anything?!?!
This card is a 32GB Class 10 Patriot. This has happened before in my old HTC Evo 4G OG with a 16GB Class 4 SanDisk card. That card became unusable after a few times of this happening except I was able to fix it those times using the methods I tried above and allowing my phone to recognize the card again.

[Q] Seriously weird things going on with my microSD card

So I have a Galaxy SIII and I use a 16g micro sd card (will call it "sd card" from here on out) for added storage.
So, I am starting to have some weird problems with my sd card. It keeps...write-protecting itself...and then un write-protecting itself.
Here are some examples:
1. Playing emulator. Save a couple times, no biggie. A few minutes past, I try to save again, and it won't work. All in all, I found out its because I could no longer write to or modify the SD card. I went in with ES File Explorer to move/delete things (through the phone, NOT PC...not yet) and I couldn't do anything to my external sd card. (I could still modify my internal sd card)
2. Plug phone into PC (windows 7 x86) via USB. Access phone through "my computer," choose "card" (which is my external). fyi: I was JUST NOW doing this. This is VERY recent. Anyway... I go in to modify my music and it doesn't work! "Files are write-protected." lol wut? Since when? A few minutes pass, and then all of the sudden, it works. I can modify music. Then I try again, and it says cannot access card: says the card (phone?) is disconnected. Then a little more time passes, and it works again, no problems.
Seriously, all of this happens within 30 minutes. Took me forever to modify my music because I kept having to wait for my card to stop write-protecting itself.
I haven't had any problems with my internal memory... I don't think...
What the BLAZES is going on?

Chances are that the problem is coming from your external sd card. Backup w/e is on it on your PC, format it and try again.

Alright, will do. Thanks.

All files on external SD card corrupt after unexpected shutdown

Hey guys and girls!
This morning my phone turned off by itself (13% battery left) and needed somewhat longer than usual to reboot (in the meantime I plugged it back in to the charger). First thing I noticed was that my whole theme got reset as well as it started showing me introductional tips ("long press here to move your apps to the homescreen, ecc.). It also started to update apps in the Play Store even though I set it to manual ... so basically a LOT of things were reset.
The biggest problem I'm having now is though that all my files (pictures, videos, music) that are stored on an external micro SD card are corrupt. It's not possible anymore to open anything. I already removed the micro SD card and put it into an adapter to have a look at the files via the laptop. But nothing, even though the sizes of the files seem OK, I can't open them.
Does anyone have a clue as to what exactly happened here? Are those files lost (at least of some I have a backup) or is there anything I can do to "repair" them? Help is really appreciated, thanks!
PS: Things like the card unmounting and re-mounting never occurred. So I can't tell if the card was dying or if actually the phone ruined my files.

Did you happen to be using a SanDisk SD Card? I've had my 10 brick 2 of those until I switched to Samsung SD Cards about a year ago and haven't had issues since.
I never could manage to recover files from the damaged SD cards.

I have a Samsung SD card and had something similar.
I guess I was on Viper Rom and basically my phone restarted around 15-20% of battery. After a long wait for booting back again, all my settings were gone.
Files and others in the SD card was okay but basically until I formatted the card, I wasn't able to boot into the Download Mode to install a new rom...
I fixed the restart issue by installing the official HTC Rom.

Thanks for your replies.
It is indeed a SanDisk 16GB card. It seems though that the card is still working (no problems accessing it via phone or laptop), just the files appear to be broken. In the meantime I also tried apps like PC Inspector File Recovery, but to no success
I'm still on stock HTC Sense by the way, no root, nothing.
Anyone know though why that happened (resetting everything, etc.)?

Hit me with a PM I'll give you a SanDisk restore tool which works quite ok. there is a huge chance some files can be recovered, some will be damaged though. Don't push any new files on the card after you tried to restore the files

HTC 10-Corrupted microSD card
I know this is an older thread, but I was wondering if there is a solution. I have an HTC 10 which has an micro SD card in it, that is "married" to the phone. When connected to a computer, the computer recognizes the phone, and the microSD card, and begins to load the folders/files. Eventually this process stalls, and the phone/drive is no longer readable by the computer. To get the computer to recognize the phone/card again, I need to restart the phone, but the same thing happens again.
I have like 20gigs of data on the card, and cannot just put the card in a reader, because it's encrypted to the phone. Any possible solutions? It's frustrating to see the files/pictures for a minute or two, and then have them disappear. I have tried copying/pasting the files while they're visible, but this often triggers the computer to no longer recognize the phone/memory card. I've tried to un-encrypt the microSD card, but the phone can't recognize/access the microSD card long enough to complete that process.
Please help if you can.
