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--

after searching, i found that the solution to the 'System UID's inconsistent' issue is to reformat the ext2 partition on the SD card.
But how do i do that. I tried removing the SD card and putting it in a card reader, but Paragon doesn't recognize the drive that way.
If i let it be in the phone and connect the phone via USB to my PC, Paragon recognizes it, and when i click on Format Partition option and point it to the SD card drive, it starts the format and then asks to reboot the PC. When it reboots, the phone reboots as well. My PC comes back and Paragon tries to continue the reformat (but the phone is not yet up), so Paragon fails with an error 'Invalid partition id'.
What the heck am I doing wrong?
Thanks in advance,
KG

if you are installing some different update like going from rc33 rc9 or whatever to dev phone/haykuro/or such you need to wipe...
I have the same problem, and wiping doesn't do squat. Can't use my phone now...
The easiest way to partition your card is to download a live ubuntu cd and use the partition editor included on the cd.
This happened to me when I had /data/data on the ext2 partition using the Symlink method for Apps2SD.
http://forum.xda-developers.com/showthread.php?t=512057&highlight=System+UID
Basically, all I did was move the /data/data back to the internal memory...
rm /data/data
busybox cp -a /system/sd/data /data
rm -r /system/sd/data /data
reboot
Had a couple of stale NFS file errors, so I could not really delete the /data directory from the /system/sd. Ended up reformatting the partition to go with a different Apps2SD method.
Used Paragon as described above and everything worked fine for me.

I tredged past it. I just redid my A2SD and then ran the optimizer (I'm on Hero btw) and it seems to be working fine and speedy.
Probably the cleanest solution HERE
Hi all.
Is it possible to unmount and remove an SD card when using CM v4.0.2 with a partitioned SD card, and CM v4.0.2 is running A2SD, while the phone is on? I just can't seem to figure it out. The unmount button is "greyed out".
If so, please let me know how.
Thank you.
i have the exact same problem....my pc wont even recognize the phone anymore....i'm trying to get the usb pop up on the phones notifications n nuttin happens
As I am tinkering, I think it has to do with the A2SD that the rom supports.
Obviously we cant be removing a card that the system is using.
I can still mount when I plug into my PC, but most/if not all(haven't tested all) the apps wont run, I get a "Please Check Your SD card" message.
I would just like to hear from someone more experienced than me(newb) to back up what I am thinking to be true.
Thanks
It's kinda weird, you can't unmount the card because you'll have issues, but on linux it mounts ext too, so you can modify the contents while the phone is running. Although whenever I've tried it's caused loops ><
@Teflon - Try using usb mode in recovery: go to the console and type to mount "ums_enable" and "ums_disable" to unmount.
Hi!
I would like to be able to remove the SD card from my phone.
I can't do it right now b/c I have Apps on SD configuration.
Is it possible to kill all running applications and to unmount the SD card?
I don't see any reason why not, but has anyone tried it already?
Thanks
The safest method imho would be to 'power off' the phone, remove card, boot phone. Cumbersome - maybe - but it's a trade-off with the excellent App2Sd.
I believe it is swap that is not allowing you to unmount/ mount to the computer, try disabling swapper and then try or download and burn an ubuntu live cd and use that to acess it, I can make changes to my ext3 partion while it is mounted in ubuntu. But I never had a problem mounting untill I started using swap which I would have to turn off to mount
Born, must of us have our dalvik-cache running off our ext partion so even if you killed all apps you could still corrupt your card
Here's what I am looking to accomplish. I wanted a backup sd card just in the event mine goes bad. I ran a search with 'SD Card" in the title and read each thread. Here are my roadblocks.... I installed DiskInternals Linux Reader and although it let me copy the ext3 partition files to my pc, it does not allow me to copy them back to the new card. Partition Manager does not have a 64-bit free version. Installed Ext2 IFS for Windows, however, it refused to see my sd card when mounted. I used RA-dream-v1.5.2 recovery to do a Bart + Ext Backup and verified the ext-backup.tar is on my sd card. I was going to install ADB, however, it doesn't say it works on Windows 7 64-bit. I have already partitioned the new card and have everything copied to the Fat32 partion. How now is the easiest way for me to get the ext-backup.tar untarred to my ext3 partition on the new sd card? Please don't flame me as I have been reading threads since 10 this morning. Thanks for any help!
The best thing I've found for managing the Linux partitions is a GParted Live disc. Just download and burn to a bootable CD. Pop it in and reboot your machine and you're free to do pretty much whatever you want with your SD card partitions without having to worry about Windows getting in the way.
Appreciate it. Gonna try it now. Thank you!
Well, I did as instructed. However, it failed to "Buffer I/O error on device sr0, logical block 57107. Any other way to accomplish what I am looking for?
any possibility that your USB port is flakey? Any way to try it on a differenty machine? I've got one PC that has USB problems and has been known to give similar kinds of error messages.
It seems fine for everything. It's a brand new Dell, only 2 months old. It was kinda freaky when I booted from the cd...lines of text scrolling on my screen for a couple minutes, lol. I was like...this better not be wiping my pc out Then at the end it just died on that error... The one thing I notice in reading threads...people keep giving console commands to do things on the phone using adb, however, I tried and it says adb isn't found... Here is an example. I can't believe there isn't an easy way to do this with so many folks rooted, etc.
----------------------------
best thing to do is this while in recovery, use adb and type
Code:
adb shell mount /system/sd/
adb pull /system/sd/ system_sd_backup
turn off phone, change sd card, go back into recovery, then
Code:
adb shell mount /system/sd/
adb push system_sd_backup /system/sd/
ok so I have copied an EXT from one card to another and this is how you do it. You need to be using RA recovery. Go into your console from recovery and type "bart -e -s EXT" that will create a back up of your EXT in a folder called "bart" on the fat32 partition of your SD card. Plug your phone into your PC and copy the bart folder to the PC. Now take the SD card out of your phone and put in the one that you want to restore the EXT to in. Copy the bart folder from your PC to your new cards fat32 partition. Make sure you partition the new card so that it has an EXT partition on it and then go into the recovery console and type "bart -e -r" it will ask you to select which back up to restore. Input the number for the back up that says "EXT" and restore it.

Worked flawlesly! Your help coupled with a PM I received from 'shadowch31' made this seamless. Thanks so much!
I tried to run the BART backup via console, but I keep getting an error message as following:
Storing app data...
tar: empty archive
Error occurred during storing of app data...
tar operation failed.
Do you have enough space on the /sdcard?

I have about 4 times more free space on the SD card then my ext-4 partition is. What could be the 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.
I think It all started when I using linux to access the sdcard of my p970 2 days ago. I tried to rejected it safely but the computer said some error so I just unplug it anyway.
After that there are some unusual thing such as missing app.
Just then I found that the phone said "The sdcard is either empty or android cannot read this type of sdcard format..."
I used a card reader to check my sdcard but it is broken, so I do a quick format to it.
After that I want to do a clockworkmod recovery backup but it failed with a message
Waiting for SD card to mount (20s)
Waiting for SD card to mount (19s)
Waiting for SD card to mount (18s)
...
Waiting for SD card to mount (1s)
Cannot found SD card marker....
then it failed.
What should I do? I want to make a clean reinstallation.
try accessing to it by an usb adapter. copy datas if possible, then format. if you can't access to it at all, it means it's dead. if memory sectors become unreadable, it's dead.
I've borrowed my brother's sdcard...it works just fine.
So I guess the sd card is broken
In addition, when I checked it on the PC, I can do quick format successfully but the full format failed every time
be sure filesystem is fat32 and well partitionned (unique partition) . quick formating is enough.
if windows is dalaying the access to the card, it probably means the card is corrupted or dying
