Can't see my sata disk suddenly.

I used to have it mounted on /home over my xfs disk(which also had a /home, but that shouldn't matter right!?). The sata disk was/is a ext3 disk. And i'm sorry but this is all i can tell:
1. i got a ext3 error spitted out on console.
2. i think, a sudo fuser -km /dev/sdb
3. sudo umount /dev/sdb

Then i reebooted and suddenly /dev/sdb doesn't exist in /dev...

edit: found a log for my ext3 errors: http://pastebin.archlinux.org/1236

Id the disk is the culprit, which tests should i run on it to see what's wrong with it. I suppose i could run some tests with some programs even though i can't even see it in /dev.

I'm running -fallback standard arch kernel, since that's the only one i got working. (For history and perhaps more clues pertaining to this problem see http://bbs.archlinux.org/viewtopic.php?id=29132)

Re: Can't see my sata disk suddenly.

which modules are needed for detecting a SATA disk?

Re: Can't see my sata disk suddenly.

put sata in HOOKS in /etc/mkinitcpio.conf
then mkinitcpio -p kernel26
see more information:

Re: Can't see my sata disk suddenly.

i've already done that zeus but thanks for the info anyway.

Is there any particular reason pata is not described in above wiki article? I see 'pata' being built with the fallback image.
What /IS/ 'pata'?

What hardware you use?

Re: Can't see my sata disk suddenly.

ok, so i added pata to http://wiki.archlinux.org/index.php/Con … able_hooks. No idea if the entry is any good as i just based it on the newspost. I will now try to reeboot with ata_piix at first in MODULES and base udev sata autodetect pata scsi filesystems in HOOKS(in mkinitcpio.conf) after having generated the new image.

Re: Can't see my sata disk suddenly.

ok, so i don't know if it was because of ata_piix as first entry in MODULES or the substitution of ide with pata in HOOKS or both, but now I am able to boot with both standard and -ck kernel by using the standard cpio image(not -fallback).

and i see:
14:05:11 ~ $ sudo tune2fs -L nydisk /dev/sdb
tune2fs 1.39 (29-May-2006)
tune2fs: Attempt to read block from filesystem resulted in short read while trying to open /dev/sdb
Couldn't find valid filesystem superblock.

That's the SATA disk. What do i do from here?

14:19:41 ~ $ ls -l /dev/sdb
brw-rw---- 1 root disk 8, 16 2007-02-10 14:53 /dev/sdb

e2fsck 1.39 (29-May-2006)
fsck.ext3: Attempt to read block from filesystem resulted in short read while trying to open /dev/sdb
Could this be a zero-length partition?

14:21:47 ~ $ sudo cfdisk /dev/sdb

Re: Can't see my sata disk suddenly.

Then i reeboted and tried good 'ol fdisk which turned out to work unlike cfdisk, so don't remove it if there ever was talk of this?
then i made a logical partition and installed xfs on the new partition aswell and moved my whole home/* over and mounted it as /home.

Maybe i'll copy everything over. We'll see when i have the time for a potential f*up
