I tried mounting it by adding this line to fstab then doing mount -a:

/dev/sdc4 /media/scsihd SysV rw,users,auto,umask=0222 0 0

but when I try to mount it I get this error:

mount: unknown filesystem type 'SysV'

I am relatively new so I have no idea how to proceed. I am assuming there are no SysV drivers installed or I need to edit the Fstab line to something other than SysV.

Please help.

Thanks.

Okay I did more research and it seems SysV was a flavor of Unix this HD ran. I need to access the data on it for a backup and can't do so without mounting it in Linux so any help would be appreciated.

Okay I am pretty sure it's an NFS filesystem after much trial and error. When I try to mount it now though I get this error:

mount: directory to mount not in host:dir format

From my (limited) understanding NFS is a transport, not a (native) filesystem.
Try cfdisk on the disk - see what it thinks it is.

If you only need a backup, just use dd to get an image - it doesn't care about the underlying fs. Doesn't help if you need to read the data; but at least you'll have a backup.

I need to read the data as well. Time to go learn some more.

How do I use cfdisk to do what you said btw?

Okay I just tried cfdisk /dev/sdc4 and it said no command found so I assume I don't have the RPM installed. I checked the package manager and realized it isn't there so I must ask you what the package is called? I noticed a cftools but am not sure if that is it.

Been many years since I swore off all rpm-based distros, so I can't help. Probably util-linux or some such.
Try "fdisk /dev/sdc" (note these things use the device, not a partition). Use the "m" command to get a list of available commands. You'll want "p" - look for the id on the right, and probably "l" to decode it.
"q" to (safely) quit.

You may have fdisk. Try "fdisk -l /dev/sdc"

If it is a filesystem that the kernel recognizes, you could try using "-t auto" in a mount statement.
According to the book "Unix Filesystems", System V Release 4 adopted the UFS file system derived from the BSD Fast File System. SVR4.1 included the VERITAS Filesystem (VxFS).

Also read through the boot logs. There may be a kernel message pertaining to this disk.

If it is VxFS, different systems using it differed enough to where one systems couldn't read a drive from another's. Here is a link to vxtools that may still help however, http://www.penguin.cz/~mhi/fs/vxfs/

I called the company today and they said it's most likely EAFS.

Is there any info on this file system? He said it's AFS but stupports longer file names so I assume the E stands for extended but I haven't uncovered anything about it yet.

Anyone know how to mount AFS or EAFS?

The kafs kernel module might enable you to mount the partition read-only.

Install the kernel-source and read the /usr/src/linux/Documentation/filesystems/afs.txt file for instructions on how to use it.

Where can I find kafs kernel module? It's not under the package manager.

If kafs modules support was selected when the kernel was compiled, then load the kernel module:
sudo /sbin/modprobe kafs
