Hi,
I just reinstall my computer with Slackware 9.0 and now i can't mount hda2.
My hardisk configuration :
hda1 Boot Primary Linux ReiserFS 3002.23
hda2 Primary Linux ext2 5996.23
hda3 Primary Linux swap 1003.49

My /etc/fstab :
/dev/hda1 / reiserfs defaults 1 1
/dev/hda2 /mnt/hda2 ext2 defaults 1 2
/dev/cdrom /mnt/cdrom iso9660 noauto,owner,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
proc /proc proc defaults 0 0

I try to mount manually : mount /dev/hda2 /mnt/hda2
Error message : mount: /dev/hda2 is not a block device

What's should I check ? Thanks

are you sure it's hda2? was that the output of "fdisk -l /dev/hda"?

Device Boot Start End Blocks Id System
/dev/hda1 * 1 365 2931831 83 Linux
/dev/hda2 366 1094 5855692+ 83 Linux
/dev/hda3 1095 1216 979965 82 Linux swap

try converting it to reiserfs makereiserfs /dev/hda2 and edit the fstab. i just did this the other day read that post.

i have data in hda2. is there anything i should concern by doing makereiserfs ? i don't want to lose my data.

it's mkreiserfs.
i've tried mkreiserfs /dev/hda2 and the message :
is_mounted: /dev/hda2 is neither regular file nor block device
Aborted

is it something to do with reiserfs ? or something wrong with /dev/hda2, cause it is not recognized as a block device ?
i've been thinking to reinstall and use ext3 but will be better if someone can help me out of this.

btw, what is better ext2, ext3 or reiserfs ?
and is reiserfs stable ? i have problem with my sound which i never got it when i use ext2 or ext3.

ext2 is not journalled (not reliable if power fails etc..) and uses fsck to fix all of it's problems. However it is one of the fastest file systems available. ext3 and reiser are journalled and are therefore more reliable but as far as i know reiser is a bit quicker than ext3.
Hope this answers you question

thanks for the explanation
but i still can't mount my ext2 partition
it seem no one know this problem so i guest i have to re-install my computer again.
