mounting external hard drive


My Iomega external hard drive was recognised and usable under Suse 9.2. Now under 10.0 there is a nice little icon for it on the desktop, but when I click on it, or try to reach the HD by other means I get "Unable to mount the selected volume -- mount special device /dev/sda1 does not exist. The material in my manuals about mounting HDs is confusing and scary. Can anyone guide me?

Does mounting "by hand" work?

Hi Perry,

I don't know my way around suse very well, but here's a few ideas.

If you type dmesg in a terminal, you'll get the log showing you whether or not the drive was recognised. It'll show up with some vendor information, and a message about being attached to /dev/sda. That's SCSI disk a, because USB drives (I suppose you're not actually using a genuine SCSI IOMEGA drive?) pretend they are SCSI ones for the purposes of the kernel.

You'll be wanting to mount the first partition of the drive, which should show up as /dev/sda1 when there's a partitioned disk there. So you could take a look at the partition table. fdisk -l (lower-case ell) should do that for you if memory serves (check out man fdisk as root). If it looks like the first partition is something reasonable, again as root, you could try mounting it like this:

Code:
cd /tmp
mkdir iomtest
mount -t vfat -o ro /dev/sda1 iomtest
(assuming you've got a Microsoft-type filesystem on it, change vfat to whatever as appropriate if not). That'll try to mount it read-only (-o ro) just in case. If, after that, you can cd into iomtest or just ls iomtest and see what you expect, then something is funny with your automounter, or udev, or pmount, and pound to a penny that you'll need to get some advice from a suse user.

If it's any consolation, I'm getting a lot of gyp from a PVR I bought recently: can't mount it at all on my Linux box, though my Mac laptop mounts it fine I think I need to learn a lot more about all this udev/hotplug/pmount stuff.

Good luck, hope that'll at least get you your files back!

Nick/.

PS: what have you got in /etc/fstab?

BTW -- I don't know what I have in /etc/fstab

All this terminal stuff makes me nervous. I'm looking wondering whether I should proceed with this, or maybe try to find a SuSe expert locally.

To view your /etc/fstab, just type as root:

Code:
cat /etc/fstab

He he... I'm the opposite -- afraid of mice

Always best to have a guru around, watch and learn (goes for me too).

typing less /etc/fstab at a terminal will list out the devices the system expects to be able to mount, one per line, along with what type of file system (MS FAT, ext3, whatever) where it'll mount them, the options it'll use to mount them, and two numbers (the order in which they are checked and whether they get dumped). /etc/mtab shows you what's actually mounted.

I don't think you have to be root to read these files.

q quits less.

Nick/.
