Troubles mounting and recognizing a Maxtor Firewire drive


I am trying to backup my Linux partition on a Maxtor Firewire 1394 300 GB hard drive. I am running dual-boot with Mandriva Linux 2006.0 and Windows XP. I used disk drake to partition the hard drive into two partitions, one mounted to /mnt/Media06_X (read-only for windows use) and one mounted to /mnt/Maxtor. I believe these are /dev/sdb1 and /dev/sdb5 respectively. I had the system working for a while where I could move files to the /dev/sdb5 a.k.a. /mnt/maxtor partition, but I was receiving an error that it had run out of memory after using only 3 GB (on a 130 GB partition). I realized that I had not actually mounted the partition in disk drake, so I went in and mounted it. I then received the running out of memory error after only filling it with 700 (ish) MB of info. I rebooted to see if that would help it mount properly or something. Now when I boot into linux, it does not automatically boot into KDE as it usually does. It prints the following screen:

Code:
                       Welcome to Mandriva Linux 2006.0
                   Press “I” to enter interactive setup.

Checking filesystems
Fsck.ext2/dev/sdb5

The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock:
         e2fsck –b 8193 <device>

:No such file or directory while trying to open /dev/sdb5
/dev/sda9: clean, 147731/2845248 files, 3635919/5687002 blocks

Then I enter “fdisk –l” so that I can show you what the system recognizes.

/dev/sda9		6898	9729	22748008+	83	Linux
Note, no mention of /dev/sdb at all. What do I do to get it to recognize the Maxtor drive again? Based on guides I have recently read, I assume the problem is that I partitioned and mounted it wrong in the first place.

Your root partition is sda7 - it seems to me - & it mounts it happily but then stops because it cant mount the external device because its set to mount at boot time - I guess.

So what filesystem in on the external device & what does your fstab look like & maybe as well what bootloader are you using & its configuration .

I sounds like a simple mistake somewhere - not sure.

I dont get it why it cant find commands - as you wont have moved files from root to external but copied them - Id think .

"So what filesystem in on the external device"

How do I check this? I assume it was originally formatted for windows. I used disk drake to set off a partition for linux.

"what does your fstab look like"

How do I check this?

"maybe as well what bootloader are you using & its configuration"

Grub, not sure about configuration.
