Mounting Logical Volumes

[sunking]

I have a external usb enclousure with a HD i pulled from an old
system I had.
It has Fedora 4 on it. But i can't mount it.
I tried:
vgscan
vgchange
lvscan
pvscan
They all give me "no physical volumes found"
I can mount it in the usuall way:
mount -t ext3 /dev/sda1 /mnt/usb
but all It reads is the boot sector, grub, lost+found.

Can one of the guru's out there show me what i'm doing wrong?
vgscan and pvscan should give me results.
By the way i'm using Slack 10.2 with the defualt kernel.

what file system was used on fedora disk? Does your kernel support it? There is tutorial on external usb drives at LQ forum. Check out the tutorials at this site too.

ext3 is the file system.
I've been to LQ and asked the same question.
That's where I got vgsan and pvscan from.
But how how do you do it for an external drive?
I never really got an ansewer from LQ.

I have an external Usb2.0 box too. It contains 160 GB Samsung IDE hard disk in it.

It is formatted as NTFS and 1 primary partition.

This command works for me:

mount -t ntfs /dev/sda1 /mnt/usb -o ro
