Trouble recovering ext3 partition

#1 Post by Dima12 » 08 Jul 2014, 05:48

Hello! First off, thanks so much for the wonderful product.

I've got a 2TB disk which had two ext3 partitions on it until I accidentally installed Linux Mint over them. One partition was 15GB for the OS and the other was the rest of the disk for media. Mint quickly and quietly reformatted the disk to have one large ext4 partition.

I've tried running deep analyze with testdisk 6.14 and 7.0. Both detect the smaller 15GB partition. 7.0 detects the large partition as well, but doesn't seem to know how to recover it:

Code: Select all

     Linux                121584   0  1 362305  73 32 3867187496
     ext3 blocksize=4096 Large file Sparse superblock Recover, 1979 GB / 1844 GiB
This partition ends after the disk limits. (start=1953246960, size=3867187496, end=5820434455, disk end=3907029168)
Full log is attached. Any ideas, gurus?

Thanks in advance for your help.

TestDisk doesn't let you recover a partition which ends after disk limit.
In some cases I've had a trick to increase the amount of cylinder using the menu geometry to make your partition accessible and at least to have a try to list your data.
Similar like in this topic:

Can you copy and paste the complete content of your testdisk.log including "Deeper Search" into your next post?
I'm missing info about your disk, your current partition structure and the results of "Deeper Search".

Thanks for the quick reply Fiona. Looks like the attachment didn't come through.

What does it mean for a partition to end after the disk limit? How do I figure out the correct number of cylinders to set?

Here's the full text of the log file:

Re: Trouble recovering ext3 partition

#4 Post by remy » 08 Jul 2014, 15:04

you probably found the good partition, but on the wrong beginning position because testdisk detected a superblock. Try to change options to match "cylinder boudary : no", and run again the deepersearch.

If it's not enough, try to select 'none' instead of 'intel' partition type. Tou won't be able to write then, but if you find the good partition you may compute LBA of beginning position and size of the partition to create a loopdevice and mount it.

Thanks for the tips, remy, I'll try them out tonight. I'm currently running deep analyze with an increased cylinder count per fiona's advice (I randomly guessed 245000). When I change the "align to cylinder boundary" option to "no", should I keep the modified disk geometry or reset it back to the defaults?

you can keep the modified geometry, doesn't matter.

I ran deep analyze with an increased number of cylinders and "align partition = no" overnight.

Code: Select all

New geometry
Disk /dev/sda - 3290 GB / 3064 GiB - CHS 400000 255 63 sector_size=512
New options :
 Dump : No
 Align partition: No
 Expert mode : No
I didn't get the "can't recover partitions" message, but when I tried to list the contents of the partitions I got an error about the file system being corrupted.

Code: Select all

ext2fs_dir_iterate failed with error 1.
Here's the full log:

Does this tell you guys anything?

I'm now running with "partition table type = none" and "align partition = no". Will keep you posted on the results.

Re: Trouble recovering ext3 partition

#8 Post by Fiona » 09 Jul 2014, 16:22

Why did you increase the amount of cylinders?
Reading of your increased amount of cylinder can cause read errors, because it's not a physically disk space.
Your disk has 243201 cylinder and your Linux-partition has 242695 cylinder only.
There might be left some space for your swap-partition also.
Why did you set partition alignment to "No".
Your partitions are aligned on megabyte boundary and testdisk will handle this automatically.

I must have misinterpreted your advice from yesterday. You wrote:
TestDisk doesn't let you recover a partition which ends after disk limit.
In some cases I've had a trick to increase the amount of cylinder using the menu geometry to make your partition accessible and at least to have a try to list your data.
Similar like in this topic:
post3435.html?hilit=after%20disk%20limit#p3435
I set partition alignment to "no" based on Remy's advice:
you probably found the good partition, but on the wrong beginning position because testdisk detected a superblock. Try to change options to match "cylinder boudary : no", and run again the deepersearch.
Any advice as far as next steps go?

Thanks again for the support!

I tried running with "align partition = no" and "partition type = none" but still to no avail. One of my old partitions is recognized and is readable while the other is recognized, but I can't list it's files. Here are some snippets from the log (it is too large to paste and I'm not allowed to attach a .log or .txt for some reason):

TestDisk exited normally.
I've tried increasing the number of cylinders, tried running with align=no, and tried running with align=no and partition type=none. Anybody have any ideas of other things I can try? I feel like I'm very close to getting my data back, but it's just a bit out of reach :cry:

Any thoughts??
