Linux Mandriva Unix Harddrive Mount

[devingoodsell]

Hello I would like to start out by saying i am not literal definition of a linux newbie. I basically know nothing. Not let me explain my problem. I have a unix harddrive in which i need to get information off of and run on the linux machine. The problem is when i go and try to mount the drive of which i want to pull the information off of it doesn't save.

In the DiskDrake application i go select the sda harddrive (a Scsi Seagate 4 GB Drive) It displays that is has an unknown partition structure here by making the partition a greyish color. When i try to go and mount the drive it looks like everything is fine, but when i click done and try to view the information within the mounted area nothing comes up. When i open back up diskdrake and the SDA harddrive it shows that the harddrive has no mount. Does anyone have any idea of whats going on??? PLEASE HELP :confused:

Do you have any idea of the file system the drive had?
ext2, ext3, jfs, xfs, reiserfs, do any of these ring a bell?

If you know this, you can create a mountpoint and get to your data.

You know honestly i am really unsure, I knkow that its a Santa Cruz Unix Version, however i am completely unsure of the partition structure. In the linux diskdrake application is just says Unkown partition Type... Is there any way i can get the partition information? Or is there any other means i can go from here? Thanks again!

-- Update on this the Operation System i believe was the Santa Cruz Unix... Or SCO Unix

What do you get with # fdisk? It should list disk devices, partitions, blocks, filesystems, etc.

You said it has no mount point, make sure that exists.

HTFS and EAFS is likely the file system(s). You need to make sure your kernel has support for these FS(s).

Thake a look here:

First, if DiskDrake is showing unknown partition, whatever filesystem is on the drive is not recognized by your system. Second, if it is HTFS, there is no open source driver module for it and given SCO's litigous nature, I very much doubt any closed source module for HTFS would ever be included by anyone, assuming one even exists.
You might try opening a console and running:

$ su
[enter root password]
# fdisk -l

That will output a lot of info on all the drives on your system, including filesystem type.

The output for the Seagate SDA4 is:

Device Boot Start End Blocks ID System
/dev/sda4 * 1 552 4433908+ 63 GNU Hurd or Sysv

I'm not a hundred percent sure, I don't use BSD's much. I do remember seeing that GNU HURD or SysV while usig a BSD UNIX though IIRC. Which means that filesystem is possibly UFS. If you have kernel 2.6.5 or newer (find out with "uname -r" at the shell) you can mount that after all according to this page. Even if I'm not exactly right with the command below, it's a start to work from.

Try: mount -r -t ufs -o ufstype=ufs2 /dev/sda4 /media/seagate

You could also switch up the type with ufstype=ufs or ufstype=44bsd etc. Im shooting blind, I truly have no idea here it's unfamiliar territory, but I hope it can help you.

HTH man. :D

EDIT: If that doesn't work because it is an SCO fs, this usenet thread may help you out.

That fdisk output could be a lot of things including HTFS from SCO. However, if you want to try mounting it as a UFS filesystem you should first run:

# modprobe ufs

That loads the driver module for UFS without which you will just get an error message even if the filesystem is UFS. The UFS module will not be loaded on your system unless there was a UFS filesystem present when you installed.

Another thing you can try is rebooting with the mandrake/mandriva install cd-1. Go through to the beginning part where your hard drives are scanned and identified. If the install program can't figure out what's on that drive, there is no support for the filesystem in mandriva. If it can identify the filesystem, note what it says and reboot. You can probably then be able load load the driver module for the filesystem and mount the drive.
