error mounting ext3 filesystem... mount: /dev/hdd1: can't read superblock

I get an error when I try to mount the ext3 partition on my second hard drive. It used to be reiserfs, but reiser gave me big problems and I switched back to ext3.

I deleted reiser and created ext3 with parted... that's when it quit mounting on me.

mount -t ext3 /dev/hdd1 /mnt/storage
mount: /dev/hdd1: can't read superblock

I'm using Slackware 9.1 and I have Knoppix Linux Live CD 3.3

By the way... Knoppix can mount the partition without any problems.

possible solutions:

- /dev/hdd1 might be the wrong device (second HDD usually is /dev/hdb - primary slave) ?
- does your kernel contain ext3 support ?

/dev/hdd1 is the correct device. i'm sure of that.
the filesystem the kernel is running on is ext3 and it was working before.

ext2/3 are defaulted in kernel...
however u say knoppix can mount it, id bet its kernel/module problem.
how about ur fstab? does it look clean?

here is my fstab:

/dev/hdc3 swap swap defaults 0 0
/dev/hdc2 / ext3 defaults 1 1
/dev/hdc1 /boot ext3 defaults 1 2
/dev/hdd1 /mnt/storage ext3 defaults 1 2
/dev/cdrom /mnt/cdrom iso9660 noauto,owner,ro 0 0
/dev/hdb /mnt/cdrom1 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 don't know what the devpts or proc are there for. My cd burner is /dev/hdb... that works fine. /dev/hdd1 is the device that won't mount.

I've had this configuration work before... it's just not working now. I can't figure it out.
