Hi,
Yesterday I nuked an old fat32 partition on my hard drive using fdisk. I
just destroyed the partition and then created a new linux partition. Then I
created an ext3 filesystem with the following command
mkfs.ext3 -j /dev/hdc1
Everything seemed fine so I went ahead and moved all my music (MP3s and
FLACS) onto that partition.
This morning when I turn on my computer I can't mount that partition! It
just says it can't read the superblock. Nor can fsck read the superblock.
Just to make sure that I had the correct device etc. I tried
dd if=/dev/hdc1 of=tmp.file
and killed it when the file got to about 200MB. I quickly loaded the file
into vim and had a glance through it and sure enough I could see some of
the names the songs and artists - they were probably the playlist files.
Is there anyway I can recover this filesystem? I've tried using debugfs and
recover but they both complain that they can't open the filesystem. It
looks like that these tools are useful for undeleting files and not for
recovering filesystems.
I'm pretty sure its not a hardware related problem (I've never had any
problems with this disk before and there are no errors in the system log).
The output of fdisk is
Code:
Disk /dev/hdc: 46.1 GB, 46115758080 bytes
255 heads, 63 sectors/track, 5606 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hdc1 1 2295 18434587 83 Linux
/dev/hdc2 2296 4207 15358140 83 Linux
/dev/hdc3 4208 5542 10723387+ 83 Linux
/dev/hdc4 5543 5606 514080 f Win95 Ext'd (LBA)
/dev/hdc5 5543 5606 514048+ 82 Linux swap
And
mount -t ext3 /dev/hdc1 /audio
gives
mount: wrong fs type, bad option, bad superblock on /dev/hdc1,
or too many mounted file systems
I'm running a 2.4.20 kernel and I'm aware (now) of the ext3 filesystem bugs
- this kernel wasn't patched with the bug fixes. Is it possible that one of
the bugs did the damage? Is there anything I can do about it?
Any thoughts or suggestions would be greatly appreciated,
Mark Phalan
