I searched the forums, but was unable to find anything relating to this.
I rooted my A500 and then installed Acer Recovery Installer 1.5, and installed CWR 1.3.4 with it. Now I'm trying to do a full backup of my device, but once I'm in CWR, It says there is zero % room on my SD card. It's an 8GB card so I know there is room for it but I think that it's not detecting it. (In Root Explorer, my SD card is under "/mnt/external_sd" and "/mnt/sdcard" appears to be just system storage. Is that normal?) Do I need to do an extra step to backup? I want to put a custom ROM on it, but I always do a backup in case something goes awry...Thanks!
Try a new microSD card, CWM doesn't work with all cards plus you're not the only one, I believe to have read like 20 times the same issue you have.
Thanks for the fast reply!
I'll try that then. I have a 32gb class 6 coming in the mail so I'll try that when it gets here.
I didn't realize it was already discussed! I searched for all sorts of related things I could think of, but couldn't find anything close. Sorry!
EDIT: I forgot to mention, I have used this card on an Inspire 4G and it worked fine with CWR. Could it just be because it's another device?
You can try out an usb stick to, it works for me like charm. I used a noname 16gb usb stick for all of my backup and restore.
I have three 8gb micro SDHC cards, and one (older) 1gb microsd card (non HC).
I only managed to get backups and zip flashing to work with the 1gb card.
So there's definately something goin on there.
I hope the problem will be solved at next release of CWR. I never had this problem because I didn't used a micro sd till now, but I´m planing to buy one to get more space. I think a list of supported sd cards would be good for all of us.
I'll try the USB stick and see how that goes for me. I didn't realize that USB was an option! It's strange though, I never had something like this happen on my Inspire so I thought I was just messing something up.

That's probably a good idea!
I acknowledge that there is most definately a problem with using some sdcards.
But something just occurred to me that some people may not understand.
If you have a USB stick inserted, clockworkmod sees that as /sdcard instead of your real microsd.
So if your trying to use a microsd card, make sure there is no usb stick connected during bootup to recovery.
If you want to use as usb stick instead of the microsd, make sure it's connected during bootup to recovery.
When I was first trying it, I had nothing plugged into the USB port, but then I tried it with the USB stick last night and it made a backup so then I flashed a ROM. I got stuck in a boot-loop though so I tried to restore it and it didn't work. I ended up just going with a different ROM. I'm a little hesitant now when wanting to flash a new ROM. If I have a Micro SD card in and a USB stick in could that be messing something up? Should I have taken the SD card out before recovering from USB? It's running fine now with the ROM, but if I ever want to flash something else, I'd like to be prepared just in case!

Hi guys
I'm having some extremely irritating problems with my A500. It doesn't detect any external sd card I've tried so far. It says external sd is unavailable under storage in settings and the external_sd folder is empty in root/mnt. I've tried 3 different cards so far with no success. Anyone have a any advice for me on how to mount the card? I think the problem might be that it doesn't get mounted when I insert it. I can't root because the GingerBreak mod that's been posted needs an external card to work. So maybe some advice on how to root some other way? Then I can try restore a stock image and see what happens.
I had to insert mine and then reboot the tablet for mine to show inside of a file manager.

Hey, thanks for the tip. I forgot to add it to my original post. I've tried rebooting with all 3 of the cards I have. I'm starting to think it's a hardware problem...
Have the cards you're testing been formatted NTFS or FAT32? If NTFS they probably won't work without some help.
The stock device only deals with FAT32 mSD cards; I haven't tried the NTFSMount app from the Dev forum on an NTFS-formatted card yet, only USB devices.

Hey. I've formatted the cards multiple times, to FAT32 every time. Might try exFAT tomorrow just to see what happens.
exFAT didn't work. Not that I expected it to, lol. Maybe the GingerBreak apk can be modified to use the usb storage instead of the external sd. Any idea where I can get the source code to take a look at?
If you've tried multiple cards, all FAT32 and all work on other devices, I'd return the tablet while you can, sounds like a hardware problem indeed
Slight problem with the returning, lol. I live in South Africa and ordered my tab from the USA since my own country is so backwards. I don't really mind not having an external sd card, I just wanna root again since almost all the apps I use need root. I'm considering returning, even if it's gonna take a lot of effort, time and money...
EDIT - Another reason I can't return it (and this is a horrible thing) is that SuperUser Permissions is still installed. The recent update made me lose root. So I'm kinda stuck with this app that's proof that I voided my warranty. The only way to get rid of SuperUser is to use some apps that all need root. To get root I need the external sd to work. To get that to work I need to send it for repairs. A very messed up situation
I'm almost positive that it's a hardware issue now. Even when I try to do an update.zip from recovery mode it can't find the file even though it's on the card. Let's hope they don't see the SuperUser app when I return it...
I thought about maybe waiting for Acer to release an update that will unlock the bootloader. But since the SD card slot isn't working I won't be able to install the update. That so much depends on one little slot amazes me. If you wanna know what the single point of failure for an Android device is, look no further.
I know some android tabs came out without external SD card support. I live in the uk and have a 32GB version and the SD card worked out the box. Maybe you have to wait for an update. Just my 2c though. You won't need an external SD to receive OTA updates though.

Here's an image of what recovery mode says when I select Install Update from external source. Seems the system can't mount the card. Sigh
I like that message at the end.... "Install from sdcard complete."
You had rooted before the update, which means it had to have seen the sdcard then. So it's unlikely that the hardware just went bad. Are the sdcards your trying of different sizes, classes, and/or manufacturer?
I'd go with the same sdcard you used when you rooted before and reformat it using the HP USB Format tool. Selecting fat32, of course. And don't select quick format. See if that helps. Sorry if I missed somethiing relevent above.
Here's the link to the HP first tool. http://download.cnet.com/HP-USB-Disk-Storage-Format-Tool/3000-2094_4-10974082.html

Lol, the "fake it till you make it" strategy. Fail Google.
I've tried it with the original SD and two other ones. My guess is some app tried to mount the external SD in /mnt/sdcard and messed up some associations or dependencies or something.
I'm amazed. After everything I've tried it suddenly worked. I was busy in settings and accidentally selected storage. And there it was in all its glory... A working external sd card! I'm rooted again, backed up and ready to roll!
To anyone finding this thread hoping for answers for a similar problem: It was a hardware problem indeed. I fixed it myself by opening the tab and bending the MicroSD slot's pins back into place.
Short story: Was running the latest (as of Dec. 4-5) ICS ROM(s) - the ones with the SD card bug - and my SD card appears to be shot.
Long story:
-----
I had been using the various betas of the ICS ROMs since I noticed Tytung's first Alpha was out and the ROMs had been improving rapidly. I guess when the headphones issue was fixed it caused problems with reading the SD Card which was documented and seems to be well known.
The constant SD messages didn't bother me much, but eventually I noticed launch icons missing and went to the Market to re-download one of the apps I use (I've been flashing so much, I wasn't sure which apps I didn't bother restoring). The Market app tells me I need a SD Card to install apps, so I just figured it's just the instability of the sd card mount for this latest batch of ROMs and I'll flash an older ROM off my SD card when I get the chance. I also noticed the messages started saying I inserted a blank SD Card but I brushed it off (couldn't look into it at the time).
I get home and find out Clockwork refuses to mount my card which means I can't easily wipe and install something else, so I switch to USB storage mode in CWM to simply transfer a ROM from my PC and my PC only sees ~30mb of my 16GB SD! I initially thought it was just some corruption but I tried all sorts of format and partitioning programs and nothing recognizes more than 30mb of space and none have even been able to format that little space that's showing.
I've been Googling for a while and came up with nothing I haven't already tried so I finally decided to post here. Is there any hope for my SD card? Being the holiday season and for once I've got most of my Christmas shopping done early, I'd rather not waste the little money I have left to run out and buy another SD card right away if it's not necessary.
-----
Does anyone have any ideas how I could fix this? I'd greatly appreciate it because I now stuck with WM6.5 and realize how much I didn't miss it for the past year
This is also a heads up for testers to be sure to upgrade their ROM ASAP (or at least to the kernel that fixes this) if they're on a ICS ROM with an SD card bug. I'm not complaining - I know this is a part of testing early builds (please ignore my sorry post count; I've been flashing for quite a while) - but there's no reason for others to go through this issue if it can be helped.
Have you tried EaseUS?

Yes,
Try Easus Partition Manager and/or MiniTool Partition Manager.
They can help but you will have to format your SD card I think.
Good luck!
I had the same problem. I plugged my card into a USB reader after it working error free, it then said it needed to be formatted and was only showing 30mb. After formatting repeatedly it still doesn't read. I haven't retired any positioning software but i think the card may just be done with.
Sent from my HD2 using XDA App
probably you'll need a replacement.
have you tried the SD formatter? there's like a 0.000001% chance it will work in your case, but why not try it?
UPDATE well it looks as though I have found a solution to my woes. I made several attempts of formatting the 2gb card in my laptop to no avail. I tried my old captivate that it originally came out of and the cappy had troubles reading it. I then stuck it in my evo and it registered instant, so I did asdcard format on my evo and then finally the tablet registers the card. In case this helps anyone else
First off someone please enlighten me on the tabs use and the way it mounts the external SD, I read somewhere that it only uses it for media files such as music books and pics. I have an 8GB that belongs in my EVO, and a 2gb that I had for my captivate I was hoping to use in my Tab for now.
Here's my story, maybe someone can shed a little light here: My tab was purchased with Stock 3.1, I was getting annoyed by the constant update request so I went ahead and rooted and installed CWM without incident, then I decided to install the Stock rooted update from here, however when I insert my SD cards they say they are unavailable. So I stick my 2gb in my laptop format to fat32 (should this be different?, typically it works in every other device I own) It still won't read, I did exactly as others point out in other threads but still I am stumped as to how the card is made available to the OS ? Now in a fit of frustration I pulled my 8gb out of my evo put the 2gb in and wham there it is, I put the 3.2 download on the 8gb popped it in tab entered CWM and flashed the update, I don't know if the 2gb is mountable in CWM I will try tonight but the 8gb was mountable through CWM however my 8gb also was not available to Android even after the update.
So what the heck is the use of the external SD and how is it used?
I think you might have an issue with your ROM,
I use my external SD for my titanium backups and other files I want to keep portable. I have used the SD card through my PC via USB and directly by putting into the PC's card reader.
Have you tried using a file manager? I use File Manager HD and the external card shows up as Storage on the left bar.
As for the filesystem, I think I may have originally formatted as FAT but I have also pulled my SD out of my Blackberry and used it to install Honeylicious through CWM,
All in all I dont think you should be having the issues that you are having...
Good luck
If it won't mount in CWM you need to format it in your android phone, that fixed it for me. Once it is formatted correctly you'll see a notification that an SD card is installed. Also my PC wouldn't see it until I put a custom rom on. Also to store items on it you can use a file manager to move things to and from it.

The 8gb card did mount in CWM but would not mount in the OS, or when it would I would get it was unavailable or sometimes even empy when I know there is only about 1 gb free space, I did not test the 2gb in CWM mainly because it was late and I needed to go to bed, but I will try tonight. The 8gb is the one I updated to rooted 3.2 with, I still need to go to 3.2.1 ? Is there a rooted Stock 3.2.1 floating around I really havent looked much into it yet
I have noticed that getting the iconia to read some sd cards is like tossing dice..Most people who have this issue says one card works perfect in every device but not in the iconia.. Some say the card will work sometimes and not others .. Some say the card works in cwm and not with file manager..
The issue here i think is that you have two CARDS THAT ARE FUSSY ABOUT mating with the iconia. OR Your rom .i would read the threads in the rom you are using.. IF still nothing that sounds like your issue ask the DEV about this.. If STILL No luck you can either try to buy a new diffrent card or flash a new rom to try and Diag. this issue..
Good luck..
Silly question
Is your microSD formatted FAT32?
If it is anything else, your unit may have trouble reading it depending on what ROM you are using - Not all ROM's are capable of reading NTFS or other file systems.
Sometimes, microSD's freak out as well, and the only way to get it back to normal is to format it in a Symbian phone (Nokia)
Also, make sure you are using the correct mount point for the card - /mnt/external_sd - Root Explorer and other apps like it can get there.
Other than that, you may just have a bad microSD, I have had many of them die for seemingly no reason.
i recently flashed thors 1.7 touch recovery and when i rebooted my sd card wouldnt mount so i tried inserting it into my computer and my computer would not recognize my sd card either does anyone know how i can fix this its a 16gb sd card and I'm not trying to spend another 40$ for another one but I am thinking this one is toast.....any help would be greatly appreciated!!!!!!!!
As far as I know, there is no way to recover them. Once they are dead, they are gone. You can find the 16gb ones now for under $20 though.

yea i thought so thanks man
You could try reformatting it. If that doesn't work, it's most likely dead.

if its a cheap card you might be lost.. i buy pny cards they have a lifetime warranty.. I Think the reason they do this is because i have NEVER EVER had a bad one from them. They are a cheaper memory provider that is often over looked for there superior quality.. Of course some other brands are backed just as well..
If your tab phone or computer will not read it . well i do not think anyone can help you.

Try Reformatting it through CWM recovery, then see if it mounts.

Try this formatter with uSD to SD adapter.

I have been able to recover photos from a corrupted SD card using the free version of this tool from Zero Assumption Recovery. Worth a try before you reformat.
My SD card was corrupted recently after my phone rebooted. All my photos and important data were recovered successfully after using TestDisk (developed by Christophe Grenier).
After recovering my files onto my laptop, I reformatted the SD card. I did it because the recovery process undeleted useless files.
Just do a Wiki search for TestDisk.

I've never ever had such a bad experience but I really don't think that the card is dead unless you pushed it hard and crack the chip.If you use a windows PC ,once you plug the card (make sure it is properly placed into the micro sd adapter) then nothing happens ,as you say (it could be auto mount turned off ) press the windows key + R and type diskmgmt.msc.
This will open the disk manager of windows OS and you will be able to see all attached devices e,g HDD partitions ,USB thumb drives ,sd card and so on.If it s still not visible try to plug the card reader into another USB port.As a rule windows always informs you once you plug any USB device.If the device is not responding it gives an error
good luck.
Not always true... I had an sd card that just died... Neither Android, linux or windows pc recognised it... Windows recognised the sd card reader was attached but "was empty, attach an sd card"... 16Gb card to be tossed...
If the card is truly unmountable/unreadable and you really need to get data off of it, you could also try the service at recoverfab.com . They start where most free data rescue and formatting software can no longer help.

You may recover data from corrupted SD card with special recovery tool, see this useful guide: corrupted sd card data recovery
hope this helps.

Hi,
I tried using all kinds of different zero assumption recovery software and sd card repair software but with no look. I thought I wouldn't be able to retrieve any of the pictures I had on my sd card. That is until I found a company called recoverfab.com, they've been able to restore the majority of the files I thought I'd lost forever. I would certainly recommend them to anyone who desperately needs files recovering from an sd card.
My SD Card had the same problem and this, all of a sudden it was unreadable! I tried every method under the sun including trying to access it through an arduino and using SPI which is the alternative way of communicating with the device. I found a company called RecoverFab who said they could read the data from the memory chip even if the erst of the card was dead! So in a last ditch attempt I sent it over to them and the day after they received it I got an email and they had recovered 100% of everything on the SD card! I have never been so happy as it was all the photos from my girlfriends 21st! Superb communication and service!
Ok, here's my case laid out. I've searched the forum to death, so I'm pretty sure what I have here is a head scratcher so I'm hoping someone can help me out.
I bought a used HD2 off craigslist. It came with WP7.5. When I plugged in the data cable (i.e. USB cable), I didn't get a prompt for mounting to SD card. I installed Zune and got all the drivers (going through the MS troubleshooting list), and the phone was able to mount to Zune with only 200 mb. No problem, right? This error is common. I find out that if I use an SD Formatter, I can clear the card, which is 16gb, back to it's original state by mounting the card through MAGDLR.
After restarting the phone, I still couldn't get more storage than the allotted 200 mb, except it had decreased to ~150 mb. My phone was filling up quickly. I researched that, under WP7+, there should be a "connections" option under settings for mounting the SD card through the cable, so I thought "Hey, maybe it's because this flash of WP is missing something." so I reflashed my HD2 to stock rom using a guide.
While as a stock HD2 (T-mobile), I had now 600 mb of space on the phone to use, but I noticed that the HD2 still wasn't sensing my card. Bad card, maybe? So I tried an 8 gb I had, a 2 gb I had, and a 32 gb I KNOW works from my tablet (and still works on my tablet). I decided maybe it was the ROM's fault, so I decided to flash android on it, since I'm used to android from my other phones.
So I follow Jayce's guide and put on the proper HSPL, MAGDLR, the right Radio, and CWM to flash a new android ROM and banish my problems once and for all.
PROBLEM, I'm stuck here because (dope!) even MAGDLR and CWM DO NOT SENSE MY CARD(S). Now I'm stuck and I don't know what to do. Is there a way to get it running at the very least? I know the microSD slot is pretty much the most reliable piece on the phone, so I don't think it's broken.... but maybe it is?
So either a) somebody help me get the phone running with any ROM or b) somebody help me figure out how to get the SD cards working.
Sh*t out of ideas here.
[edit] OK! I FLASHED IT USING THE OL' HOLD DOWN THE "DOWN VOLUME BUTTON AND FLASH THE STOCK" Could still really use help with the SD card sensing thing though....
it wouldn't be the first bad sd card slot reported here, so, reliable it may be, break proof it isn't.

I had a bad SDCard too, it doesn't work in recovery but does in the ROM... I think you should really think about replacing your card. Flash memory has a limited amount of writes, so I wouldn't be surprised if you lose your data or find it unusable one day.
