Problems Mounting USB drives

plainkeyman · 07-13-2004, 03:07 PM

I hope you guys can help me -- I have 3 usb portable drives:

80gig harddrive 'bigDrive'
20gig harddrive 'archos'
dvd burner

Q1: Is there a correct way to find out which device these are ? when i go to mount with:

Code:

mount /dev/sda1 /mnt/location

-- i don't really know whether to use /dev/sda1 or /dev/sdb1 or /dev/sr0.... i had to look at the bootup log to see.

Q2: my /etc/fstab is:

Code:

/dev/sda1        /mnt/bigDrive    reiserfs    defaults         1   1
/dev/sdb1        /mnt/archos      vfat        user         1   1

but if i plug in my archos drive before my 'bigDrive', it gets mounted to the wrong location. is there maybe a way to fix this?

thanx in advance, plainkeyman

I'm not exactly sure how to pull this off, but I'm pretty sure you would need to use labels (like in /etc/fstab) so each drive is referenced by the label instead of the device.

Sorry I wasn't more help, but that should give you a bump in the right direction.

Hi, i would go about it like this:

-plug in all the devices and boot
-run 'dmesg | more' and 'lspci | more' to ascertain where the kernel puts the devices
-enter the locations in fstab

That should fix things unless you have some configuration issues.

Hope that helps

thank you for your replies --

it seems when i plug in my 80gig right after i boot, it uses /dev/sda1; but if i reboot, and plug in the 20gig, it uses /dev/sda1 as well.

is there a way that i can maybe specify a serial number or something?

or maybe i have something configured wrong.... but this is whats happens right after a default slackware install (9.1)
tell me which configuration files to post here if that would.

thanx,
plainkeyman
