I think my A-Data 8GB Class 6 SDHC is hosed. Is there anything else I can try before I have to purchase one? This is what I have noticed and done to try and resolve.
I cannot write anything to the card. However, I can read from it. I’ve tried deleting folders and files. They show they are deleted; however, when I take out the card and reinsert it shows back up. It does not show up as a drive when I hook it up to a card reader. Disk Management scan showed nothing. When I connect the Touch Pro to the laptop as a drive instead of Active Sync, the storage card does not show up. I can go through the File Management in the Windows Mobile app and see the storage card. Format is not available. A friend with an Android tried reformatting it and it just sat there. He took it out and resinerted his and it started formatting his card.
Is there a format program to use on the phone (searching now)? Is it time to buy a new SDHC?
ETA...I just installed FlashFormat from cnetx. Received "No storage card detected". Is there another good flash program?
You can try a card reader in your pc (ether built in or USB) to format the card. if you need help let me know.
btw a good program to format anything on windows is called swiss knife and its available for free here:
http://download.cnet.com/CompuApps-SwissKnife-V3/3000-2248-10070864.html?part=dl-CompuApps&subj=dl&tag=button
Yep...I tried a card reader to my laptop. XP did not see the card. However, I tried a different card and it showed up.
I will look at swissknife.
Swissknife does not see the card.
I ordered a new card.
I feel like I'm missing something, and I'm hoping that someone went through this and can make me feel less inept.
Just got my new GTablet. I bust it open, run the update from viewsonic, reboot. Then, I go to install clockworkmod and I can't get my PC to recognize the SD card. When I look at the browser on the tablet, unplugged from USB, I see the "SDCARD" directory, but it is there whether I have the card in or not. I plug it up to the PC with the card in it and the only thing that shows is the 13GB storage on the tablet. Unlike my Android Phone, which shows the phone memory and the SD memory as two separate removable disks, I'm only seeing 1.
I've formatted the SD card on the tablet, which does see that there is a card, but aside from that, I can't get to it... ideas? Am I missing something obvious?
On the PC: the internal memory is seen as SD1, the external SD slot is seen as SD2
After you formatted your Micro SDHD card on your G tAb, did you mount it ?
I've mounted, unmounted while the tablet was plugged up and not plugged up. I threw it in my HTC Incredible to see if there was a problem with the card, but I can browse to it fine through my phone. I formatted it on the PC (FAT32) and tried again. I see The SDCARD and SDCARD2 on the tablet, but it never shows up on the PC. The only thing I see is "Removabled Disk" with 12.7 of 13GB free.
So, I've now tried a new card, with still no go. I mean, I added clockworkmod to the SD card via windows, tried to boot to it through recovery, but it goes to the unpacking splash screen and reboots after 10 seconds. I can go into the file explorer and see the update.zip that I added to the SD card at /sdcard2/... Any help would be appreciated. Help =(

This is normal behavior for the G Tablet. Only the internal memory will mount on your PC.
Thanks for that. I figured it out after reading through a lot of the guides that directed me to install from the internal "SDCARD."
Since reading your post, I've got everything up and running with Cyanogenmod installed and running... Thanks to everyone that threw your two cents.

Hey guys,
Up until now I was using a SanDisk 8gb microSD card with my Nook Tablet when the SD icon had a "!" next to it and said the SD card was damaged and needed to be formatted. I've had this happen before and usually taking it out and popping it back in usually solves it, but this time it didn't work. So I tried to format it, and every time I tried it said that formatting failed.
So then I tried putting it into my computer to format it and my computer can't even recognize the card. It seems as though my NT essentially "destroyed" my SD card to where it's not even readable anymore. Thankfully I have a 16gb card from my old Fascinate I'm using now, but I'm afraid the same will happen to it before long.
Does anyone know why this is happening and how to fix it?
Thanks!
You could try reformatting it in Linux. If you don't have access to a machine with it installed you could download a Ubuntu live CD image to do it. I've had this happen to me in the past and that worked. Do you unmount your SD before removing it?

This. Exactly. If anything is going to recognize the card at all, it will be gparted.
I completely forgot that you can also download a live disk of GParted:
http://gparted.sourceforge.net/livecd.php
Noob here. Device is 16GB NT, rooted 1.4.1, using Albert's SD card. Works like a charm, but various apps show that they are not compatible with the NT. I would like to try the external CM7, and flash it to internal after I try it out.
I have tried several SD cards, (8GB Sandisk Class 4, 32GB Sandisk Class 4, 8GB Transcend Class 4) and two ways of imaging the CM7 file (using Winimager32 with the SD in an SD/MMC reader/writer on my laptop, using Winimager32 with the SD card in the NT). After imaging the SD, I have attempted to boot without expanding Partition 4, also with expanding Partition 4 using Gparted, and expanding Partition 4 using EASEUS Partition Master and Mini-tool Partition Wizard. I have gone back to a clean SD by using Windows to reformat the card, and by using the NT to erase and reformat.
I think that I must be missing a simple step in the process, but after searching XDA, Tabletroms, and Google, I am unable to come up with a solution.
Questions that I have are:
- Is it necessary to clear the dalvik cache when using the SD card? (I don't think so, since all boot and setup activity seems like it does not include the internal boot/system files)
- I came across a thread that says that a "cache" folder should be added to the root of the "data" partition. Is this a required step?
- Do the second and third partitions require the "system" and "data" labels?
- I set the attributes of Partition 1 to Active (LBA). Do I also need to set a boot attribute?
I apologize for the long-winded post, but I appreciate any pointers that you can provide. BTW, the efforts of all those who have taken the lead to improve the NT are first class, and the help provided by members of the XDA community here are impressive, to say the least.

If you mean you're not able to boot up at all, try plugging your NT in then turn it on. Some people's NTs will only boot when attached to the cable.
Re: Android Won't Skate
Thanks for the quick response. I left out a few items in the original post.
I have to tether my NT to the plugged-in charger to get it to boot with the SD card installed. I get the Team B splash screen for about 15 seconds, then it goes to a black, backlit screen. I have waited as long as 20 minutes, but nothing happens. I have also popped out the SD card, and reinserted it, as have others in this forum, but to no avail. When I power on untethered, I just go to the normal NT boot.
If I boot up normally, insert the card and use ES File Explorer, I can see four folders, plus the boot.img, flashing_boot.img, MLO, and u-boot.bin. Also, when I use GParted, I can see the four partitions, and when I use ext2explore, I can see many files in both of the Linux partitions.
Hope this adds a little more clarity to the original post.
Thx.
You shouldn't have to make any changes to the SD card after you write the image to it. Just put the card in and power on.
it 'sounds' like its your sd card. did you try it with just the one ? imho, because the card is choking... go get a 4 gb class 2 and try again.
1) sdformatter, fat32, not quick...
2) then use 'Win32DiskImager.exe' . . .
Android now skates
I finally got CM7 to run from the SD card(Sandisk 32GB Class 4). Used another PC to image the SD card. Worked on the first attempt.
Hope this helps others who have had this problem.
the main thing that those of us who came from nook colors will know is dont use laptop sd card readers.. prolly half the posts i seen were due to using one of them. the best SD card readers are the PC ones and using a proper image writer.
as far as the app issue.. if its like the nook color you can always edit your build.prop to make it show as another device on google play
I seem to be having somewhat of the same problem.
I got an 8 GB (4) and burned the CM7 image to it using win32diskmanager, then used easeus to partition my drive. Put it in my nook, perfect, everything works.
A few days later I got my 32GB (4) card in the mail and did the same thing. Put it in my nook, and it wouldn't boot. I can see the TEAM B+ splash screen but nothing else, screen turns black afterwards and nook reboots to nook stock.
I don't know why it does this, could be sd card problem.
Im I missing something? do I have to do anything special if im using another sd card on the same nook?

If it worked perfect the first time, it has to be an SD problem or a burning problem. I'd try rewriting the image to that SD card.

So I reformatted the 32GB card using SDformatter (lost 2GB in the process) and burned the image one more time.
Same thing happened. Nook keeps booting back into stock (after team b's splash screen). I re-insert my 8GB SD card and it works perfectly.
Must be the SD card unless someone knows what else is happening... I guess thats what you get when you shop for SD cards on ebay.

You might want to try booting up with the power cable in. Some of these SD cards and NTs just like to be difficult, but it's worth a shot anyway.

Very peculiar things are happening.
I had put my 32GB SD card away until I read your last post, thinking I might try to reboot from card with he power cord like you suggested to see what happens. So I put my card in and it loads to stock nook. No CM7 splash screen like before. I reset the device and tried again, nothing.
I think the card might be bricked now. I checked to see why this was happening and now my devices won't see the SD card. The nook asks me if I want to reformat the card, but it crashes if I choose to do so, and windows won't see the drive the card is on so i'm not able to format or play or see the partitions.
Edit: Wow. Ignore that. As soon as I posted this my device finally reformatted the card. Will try again now.

As long as the SD card mounts, you should be able to get your card back to normal by deleting all the partitions then creating just one, formatted as FAT32.

Re-burned the image. Nook will not start at all now with the card in there. I played with the power cord and left it there for 2 minutes and it powered up, however, no splash screen or anything, boots to stock NT.
I turn the NT back off, same thing, won't power ON. I wait two minutes with power cord on and it powers on then.
Bad SD card?
Card has:
.android_secure
Android
B&N Downloads
LOST.DIR
My files
boot (img)
flashing_boot (img)
MLO
u-boot.bin
When I had issues, I followed old fart's suggestion and reformatted my card with sdformatter first. then burned the image with Win32diskimager, both on another PC. When finished, I ended up with a 3.8GB image on the SD card. Nothing worked until I used the other machine. After I was sure that the card was going to work, I expanded the fourth partition to use the rest of the space on the card.
BTW, I had to use the USB cord, plugged into the charger to boot up. Worked on first try. Been happy ever since.

okay, you got me really curious. . . . what's the 'other' machine and what did it do right that the first attempt / machine did wrong. hmm ?

What do you mean by nothing worked until you used the 'other' machine?
Sorry for the confusion.
I made many unsuccessful attempts to make the sd card on a Sony laptop, using an sd card reader in one of its USB ports. It wasn't until I switched over to the "other" machine which is an old Compaq desktop, that I was able to get a good image on the sd card. The point is that I had to switch to different computer to create a good image. It seems like something on my laptop prevented me from making a workable image on the sdcard. Hope this helps.

It could be the read/write speeds. What I do is I use the nook as my card reader, since I dont have a card reader on my PC. However, I do have one of those USB card readers. The difference between them is that when using the nook, it writes at about 3-4mb/s while the usb card reader writes at about .5-1mb/s.
Hello,
So my sd card (16gb) appears to have stop working and the phone gives me the message “SD Card is blank or has unsupported filesystem.” This started yesterday after I changed default storage for my camera to sd card. Before that it was working just fine.
I restarted the phone, no luck with that. Turn off phone and remove and cleaned sd card, still no luck. I plugged in my phone to the computer to access the sd card, but did not show up, I guess its cause the card is not mounted? So then I thought I’ll just plug in the sd card to my computer and back up everything and then format to correct, but no that didn’t work… when I plugged it in my computer, my computer did not even recognize my card.
At first I thought maybe my adapter is broken, so I plugged in a spare sd card (1gb) I had lying around and that on worked just fine. So I googled what could be wrong and read that it could be that the adapter does not support HCSD cards. So then I plugged in my sd card into a USB sd card reader (which had a slot for micro sd which I used), but same thing – did not recognize 16gb card, but it did for 1gb card. I checked to see if it’s a driver issue, but it was up to date. Then I doubted the USB card reader didn’t support HCSD like the adapter, so I went out and bought a new USB card reader (one that works with HCSD cards) from bestbuy (Insignia SD/MMC Memory Card Reader). Still did not recognize card with new reader on computer.
I googled to see what my options were, but the solutions that I found all had the computer recognize the card – which mine isn’t doing… but I still tried a few things I read like chkdsk in command prompt, but I got “Cannot open volume for direct access” error.
Even though my computer does not recognize the card, my phone does recognize it but corrupt and offers to format. I also tried it on different phones (Galaxy S2 T989, and Blackberry Bold 9650) to see if it can read it, but same thing it recognizes it but corrupt and unreadable.
I’m still looking around for solutions, but if anyone can help me with this, please do. Please let me know if you need more info.
Info on devices/cards:
T-mobile Samsung Galaxy S5 16gb – 5.1.1 stock rom – no root
16gb micro sd card class 2 – got it with HTC HD2
Micro sd to SD adapter – got it with Samsung Beat T539
Focus camera card reader - got it with camera bundle
Insignia SD/MMC Memory Card Reader
Galaxy S2 T989 – was using latest stock rom – no root as well.
Computer – Lenovo Y50 running windows 8.1 currently. only few months old.
Sounds like the SD is toast. It's not easy to extract corrupted data from a micro sd card
