earlier today i checked my phone out, i have apps2sd, and out of nowhere none of my programs could be recognized. I got an error saying that the card was blank and unreadable. So i formatted it with windows vista. When I did that the paragon partition manager couldnt move or repartition the card. SO i tried deleting the partition that the Windows put on the card so that way I could repartition it in Paragon later and hopefully have it work but now windows wont recognize my card! What happened and what can I do now! arg help!

I've used SD Formatter a few times. It helped when Windows wouldn't recognize my card either.

I have had similar issues to this. I just formatted it in the phone and it formatted the entire card and got rid of the ext2 partition, then my computer read it fine and I was able to format to fat32 then re-partition it with paragon
But my problem is that not my computer or my phone is recognizing my card. I tried the sd formatter and even that didn't work. Its like I removed the way that the card would even be bootable. Its a class 6, 4 gb card so I want to get it back. Idk whats going on. It wont recognize it at all.
Im having the same problem I think, my phone reads the card fine, but Windows doesnt, and I reformatted it as an FAT32 and Windows still wont pick it up this wuld really help since I jus bricked wit the new SPL and I had the new radio, how gay
happened to me.
open up paragon and see if you can format it...
if it shows up and it wont format then atleast try to assign a drive letter to it.
after i did that i inserted the card into my phone and restarted the phone.
the phone recognized that the card was not properly formatted and then it formatted it.
after that your computer should be abl to see the card and you should be able to reformat into ext2/fat32 combo if you want
or atleast thats what i did.

That's sounds gr8 and I would definitely do that, but paragon nor windows even recognizes tht there is something in the sd card slot. When I put the card into the phone it doesn't even know tht there is a card in it. Do you think I would have better luck if I place the sd card in the phone and plug the phone with the usb cord into the computer?
Something else just occured to me, after you said to assign a drive lettter to the card. It might nt have a letter assigned to it so tht might b why it won't show up on the computer of phone. Is there a way to assign a letter to the sd card w.o. it appearing on the computer? Or a way to manually tell the computer that the card is there?
Try using the defualtly assigned letter to do a fromat directly from a cmd prompt with administrive privliges. That worked for me even when windows didn't recognize my card.

Ok tht sounds like it might work. I guess I woulf use f:/ as the default letter right? Thts what it was before it started doing this houdini thing. And how do I use the command prompt to format the card? Remember tht nothing happens. I've tried to use 2 different computers to discover the card. One does nothing and the other starts to freeze wen I plug the card in. I'm also using a memory card reader.

Something of use from M$ themselves
If that's what it was using b4 then ya probably go with f:. Open a command prompt and input format F: it should ask you if you're sure. Say yes and its done.. I would actually try using the computer that freeze's just don't try and access the card, only try the format.
GoodLuck!!!!
Im trying to do the formatting thing on the command prompt but it says that the specified drive does not exist. im really lost. How to i get my sd card back now?
how old is your card? its possible it is dead, especially if you're doing apps2sd, all the read/write cycles will shorten the life of it.
you may also try clearing the partition table with a linux command:
busybox dd if=/dev/full of=/dev/block/mmcblk0 bs=1k count=1
do this under adb shell or terminal with the SD card in and you should have a "new card". pull the card out and plug it back in. now you can format the card using the phone or a computer, then follow the steps to partition it again.

I only got the sd card about 2 weeks ago and its been working fine until now. I also asked Marcusmaximus what the damage was to the sd card if I applied the dalvik-cache and the apps2sd to my card and he said it was minimal.

I tried your command in the adb shell and in the terminal of the sd card and it responded back on both devices
C:\sdk\tools>adb shell busybox dd if=/dev/full of=/dev/block/mmcblk0 bs=1k count=1
1+0 records in
1+0 records out
I tried to format the card after and the computer nor the phone would recognize the card still.

I did try this before I post. After I used the command and put the card into my card reader, Windows immediately asked me to format the card.
I think vold may interfere with this process though, try this under recovery mode if you can.
Do you mean for me 2 restart the phone and place it in the mode with home and power buttons pressed. Then do the alt x command? Sry bit of confusion when u say recovery mode.
try...
Control Panel > Administrative Tools > Computer Management > Storage > Disk Management.
see if it picks up your sdcard there, if it does, format it to FAT and restart what you did.
if not, get a new card, i don't see another way.
try turning on USB Debugging from your phone and then re-connect to your computer and if your computer doesn't read it try rebooting your phone!! this process worked for me!!
1. Turn on usb debug
2. reboot(both comp and phone)
3. connect to comp
walla!
well it worked for me!

I'm using multiple partitions and Apps2SD. First I can't unmount my SD card to eject it because that option in "settings" is grayed.
Plus when I "Mount" the card via USB through the phone, the connection lasts < 1 minute before the phone does something (glitch?) and the computer reports that the "USB device was disconnected" or something and the phone remounts it for itself.
I'm using an ext2 and fat partitions. At first I thought that the swap partition was what kept me from ejecting so I reformatted for just the two partitions. If I go back to the 3 partition scheme, will I be able to unmount and eject the card, or mount via USB?
as for getting the computer to see the card.
Plug your phone in, don't mount sd.
Stop the device by right clicking the icon by the clock.
Unplug the phone.
Plug the phone back in and mount the sd.
should be ok.
not sure about unmounting it from the phone, I use swap, always have so I have no idea.
So there is no way to unmount the SD card?
for the first problem it sounds like when you reformatted your phone, you did it from your computer rather than the phone. (i did this once and that same problem happened). to fix you must reformat the card properly.
and the 2nd problem, it sounds like your using older an usb port. u need usb2.0 to hook the G1 into

No. I used sdparted to perform my partitioning.
I formated my SD card on my mac as fat32 and now something strange has occured. It seemed to format fine, and I can add things to the card in both OS X and Windows, and Android, however now I cannot format the drive on the windows PC no matter what I try. The disk mounts in windows fine but when I right click and go to format, the SD card umounts and I get the pop-up message:
There is no disk in drive E:
Insert a disk, and then try again.
I think something weird happend when it was formated on the Mac.
My goal was to gain root access, which I've done in the past, but however the Mac disk utility formated the SD card, I cannot get the phone to recognize the DREAIMG.nbh file upon restarting the phone using the rooting method outlined in these forums.
I tryed a few different methods to format the card in windows, including diskpart, and through managment tools. The same thing happens with all methods.
edit: I also tryed formating using the format utility in in Android. It formats fine, but something is still wrong, it will not format in windows.
Any help would be much appreciated.
are you sure its a mac to pc issue? can you add files to the root of the sdcard and such on a mac
Yes, I can add files to the root of the card on the mac.
Whatever the mac's disk utility did during the format, the PC does not like.
Dude same thing happened to me
I found a work-around that. use a an sdcard reader (Usb or the one that comes with the sdcard) I formatted mine that way so I could use it.
Thank you! This worked.
no problem =)
I have been trying this for a day and nothing seem to work so far.
The SD card is working, it can be detected/read/write from phone/pc/mac ,
I can also use the sd card to flash rom onto my phone and all works perfectly,
with disk utility, it confirms the correct partition, 64mb for swap and 1024mb for apps,
(it can be detected but cannot be mounted on my mac so no verify/repair can be done on the partition, but the fat partition can still be verified)
now, when i tried to enable app2sd, my phone says extfs partition cannot be detected under spareParts/data option.
I have tried
repartition the sd card like 20 times
wipe/reflash rom,
wiple/reflash different rom
tried different sd card , the partition works so it's not my phone/partition method
verify/repair sd disk
are there anything else to do to repair? or is it a lost cause?
any help will be appreciated
thanks in advance!
do you have any linux handy? could you do an fdisk -l on the disk and print us the partition table?
perhaps you could also use some windows utility to have a look at the table, perhaps it complains about something, if there is an error.
it may be possible that the sd card has an error in the filesystem area. you could try to plug the sd card into the pc, format it with just one partition and uncheck the quick format option. this way it would check all sectors. you should use the console version of format, i think it should output if there is an error. alternativly i think chkdsk -f prints out the bad bytes and there is another option to make it check for them (but normally a non-quick-format does just that)
thanks for the quick response,
I format with PC and MAC then do the disk check and the first time I did it was with a mac it found 5 cluster file and repaired and have since been error free with only one partition present.
I am gonna try to do the check with terminal see what i can come up with.
fixed
knowing that it's not my phone and not my firmware, I decided to give up on the card even though it's "partly-working".
bought a new card and everything fine now.
However, extensive research showed a lot of people have similar problem and some of them have found the fix by
1. reflash
2. insert the card "correctly"
that's all.
Using Amon_Ra Recovery is not working now for some reason...been waiting over 30 minutes for it to finish partitioning...but it just keeps on going. (16GB card)
I tried using ROM Manager...it said that it worked...but didn't.
Now trying to find a way to partition the SD card...easy as possible.
ADB commands? is there a windows utility?
gparted
.
Windows won't help you at all, since it's not able to recognize multiple partitions on SD card and/or EXT2/3/4 partitions.
I have the same problem....the Rom Manager dosen't get the job done.
Why can't recovery partition my card anymore? Weird! When I pull the battery after 2 hours and check the card....it has a partition (unusable) with just below the amount I set it for....
So, this time I figured that I needed to keep it in a bit longer so I left it there for 8 hours (while I was sleeping) and it was still going. So, another battery pull and format of the sd card...
Is my phone telling me that I don't need to have all the apps I want?

Not at all true. I've partitioned mine and others many times on windows (tho of course not with built in software as windows has no native support to EXT 2/3/4 partitions), but if you use something such as gparted, acronis disk editor, partition magic, etc that WILL most definitely work.
That being said, you will not be able to do it via USB cable plugged into phone/pc.
OP, do you happen to have access to a card reader? That would be really the only way to format it from a computer.
i used paragon partition manager
worked fine
+1 for GParted
hello every one,
today i had fased a strange prob. which i want to share with u all.
i am having google nexus 1 with cynogenmod 7 installed.
and having sandisk 8gb microsd card. and suddenly today morning it says that "SD card Blank or has unsupported filesystem." i took out my card and mount on my computer and take the entire backup of the data and format it. and incert it but still having the same prob. nothing happen, then i search on net i found on other threads that download the sd card formater and try it. i also tried the same but nothing happen, then on other thread it was mention that try to run chkdsk on computer, with /x comment.. i also done same but still prob. is same.
i am having 3 more micro sd cards of different brands and of different size i also tried them but giving same prob.
nothing happening.
i also open the terminal emulition in my phone and type the commmand mount -a but it says that /etc/fstab not exist.
tell me what i do ? even i am not able to do anything ...
Wow--that is tough to figure out and i am not good at this level of TS.
Sounds like you lost the mount point. It is in etc/fstab
Do you have a backup rom on pc that you can extract etc/fstab from or can you install that rom thru adb with no sd card--
http://www.addictivetips.com/mobile/how-to-install-a-rom-to-an-android-phone-device-without-sd-card/
Can you mount card thru adb--
adb shell
mount /sdcard
exit
Did you use full ersase on and size adj on when you formatted card.
Can you format and partition card outside of phone.
Also, when formatting and wiping for flashing new rom you may want to get Temasek's Format zips that include boot and system wipes.

Someone will have a better and more accurate answer soon--
