Angry mount: you must specify the filesystem type


We received some client data on an external USB drive. We plugged it into our CentOS 5.5 machine and I ran an fdisk -l which gave me this new info:

Quote:
Disk /dev/sdf: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/sdf1 1 19457 156288321 83 Linux
When I try to mount the drive using these commands:
Quote:
mount /dev/sdf /mnt/client-disk

mount /dev/sdf1 /mnt/client-disk
I get the following error:

Quote:
mount: you must specify the filesystem type
I have the following in my /etc/filesystems

Quote:
ext3
ext2
nodev proc
nodev devpts
iso9660
vfat
hfs
hfsplus
I have tried to mount the drive using ext2/3, hfs, hfsplus, ntfs and nothing seems to work.

I ran a strings on the disk in hopes of getting some info from the disk. Here is the top portion:

I was told by the client that the disk is:

Quote:
It is linux 83 filesystem.
Machine os is centos 4.8
Anybody have any ideas on how to mount this sucker?

Help before I throw this thing against the wall to open it LOL.

Try:
file -s /dev/sdf1

All linux filesystems have a partition ID of 83 and it does not specify which filesystem. Could be jfs, xfs, reiserfs, ext4 etc etc... and the actual file system used may not be supported in the default kernel.

file -s /dev/sdf1
/dev/sdf1: data

file -s /dev/sdf
/dev/sdf: x86 boot sector; partition 1: ID=0x83, starthead 1, startsector 63, 312576642 sectors, extended partition table (last)\011

What does data mean?

Interesting... Not sure...

Correction:
Not sure about

This indicates sdf1 is an extended partition and not a linux filesystem. So where is the data?

Not sure. Would be nice to know LOL. I am beginning to think the disk has no data on it and they made a booboo creating the disk for us. My other theory is could they have used a program like truecrypt?

No. Do you have any information on this disk, OS etc?
Maybe mpio or rdac disks which I have not had the pleasure of firsthand experience.

We ended up sending it back to the client and they confirmed the disk was indeed a bad one. Thanks for all the replies.
