Lo

Fairly new to linux , so bear with me.I'm running kernel ver 2.4.20-20.7 on a rh7.3 machine , with the nvidia chipset (if that matters).



Ok , trying to mount a removable hdd and i get the following error:

mount: /dev/hdc1: can't read superblock

When I do a dmesg i get the following:

hdc:end_request: I/O error, dev 16:00 (hdc), sector 0
end_request: I/O error, dev 16:00 (hdc), sector 2
end_request: I/O error, dev 16:00 (hdc), sector 4
end_request: I/O error, dev 16:00 (hdc), sector 6
end_request: I/O error, dev 16:00 (hdc), sector 0
end_request: I/O error, dev 16:00 (hdc), sector 2
end_request: I/O error, dev 16:00 (hdc), sector 4
end_request: I/O error, dev 16:00 (hdc), sector 6
unable to read partition table

Can it be the kernel , or should I start ordering another motherboard?

Any help would be appreciated.

I take it the drive is partitioned and formatted? If it is, you could have a defective hard drive. Unlikely to be the motherboard.
Try reformatting it which a bad block check enabled if reformatting is an option.
Otherwise, you could have a faulty superblock. Try using another superblock. Being new to linux, you are probably thinking, "What is he talking about?"
If your filesystem is formatting as ext2 or ext3, check out the man page for e2fsck :-

man e2fsck

It will explain what I'm talking about and it will also tell you how to check your filesystem.
If you are having problems with this, just write back.

What kind of removable drive do you have?

Lo

Thanks for the feedback.

Prob is , it's our offsite backup hdd , so formatting is NOT an option.

Thing is I can mount it on our original server (i have configured 2 additional backup servers) , with kernel 2.4.18-3 , so with my limited knowledge i asumed it was maybe the kernel.

it's a western digital 250G , i also have the same prob with the 120G

ta in advance

Check the output dmesg to see if the drive is being recognized.

Since this happens with all drives could it be the mount and or / cabling went bad? Do you know how the mount is configured?

Do you have more then one removable mount on this PC?

lo

these are brand new amd machines (new cables , removable hdd bracket etc) , so doubt it's that.

i checked out my fstab records and found this:

/dev/hdc1 /mnt/offsite ext3 defaults,noauto,0 0

hope this helps a bit....

The only thing I can think of is that the drive is not seating correctly in the mount.

lo

actually tried mounting it without the hdd bracket also , no joy.

will do some further tests and come back to u

ta anyway
