hi,
I have nstall second on my linux box. I used fdisk created 3partitions /dev/sdb1, /dev/sdb2, /dev/sdb3. I can see them fdisk -l.
I want to mount them to linux but have some errors.
1. I used command
      mount -t ext3 /dev/sdb1 /work1
 is ok without problem but I used another command
      mount -t ext3 /dev/sdb2 /work2
gave me error msg, Wrong fs type, bad option, bad superblock...

How can I make it work?

2. I want to put them in fstab file to mount them when I reboot machine
...
/dev/hdb1               /work1                  ext3    defaults        0 0
/dev/hdb2               /work2                  ext3    defaults        0 0
...
but they did not work.
What is the correct configuration?

Thanks,
Yan

first you have to format them (like in dos: first fdisk -> format) on linux:
partition and then mkfs.ext2 -j /dev/sdb1 etc.
the -j makes it an ext3 filesystem.
If you need other options (more/less inodes etc.) please consult man mkfs.ext2

the in fstab you need to put the /dev/sdb1 .. /dev/sdb3 entries there (you had /dev/sdb1 .. /dev/sdb3 according to the first line of your question)
not /dev/hdb (unless you allready had a hdb device)

Not the solution you were looking for? Getting a personalized solution is easy.

Thanks,
I was missing the command mkfs.ext2 -j /dev/sdb2.
And I have replaced /dev/hdb with /dev/sdb.

Everything is fine.

thanks a lot.
