I just put a USB hard drive into service, but find that unless the drive is connected to my PC the machine won't boot and drops to a shell. Below is the line I added to fstab. I thought that the option "noauto" would prevent the machine from trying to mount the drive
/dev/sdb /usbdrive ext3 user,noauto,rw 0 2
What am I doing wrong? Any advice is welcome.

The last entry is the fsck order used at boot. Setting it to 2 probably prompts the system to check it.
Anyway, you shouldn't need to add explicit entries to fstab to mount usb drives. They should get auto mounted when you plug them in (I think the autofs and haldaemon services are required to run for this to happen).

Also, if you add a partition label to the USB drive, HAL should then create a mount point of the same name, under /media/PartLabel.

Yes, indeed. Automount only works if the drive or partitions on it have a label. Apparently HAL is not smart enough to create a random mount point if the device/partion is unlabeled.

Really? I thought you got /media/disk in that case.

Strange. I guess my memory is playing tricks on me. I seemed to remember I recently had an issue where an USB stick wouldn't auto mount and I concluded the fact that it was unlabeled was the cause.
But trying to mount an USB drive with unlabeled partitions on it indeed mounts them as /media/disk, /media/disk-1 etc. Sorry for the misinformation.

haldaemon yes autofs no
The auto-mounting of removable media on the local machine now happens as an interaction between hal and your *windowing_environment*.
i.e. in with gnome I, as a normal user, have to go to Start(chaos symbol) -> System -> Preferences -> Removable Drives and media Which brings up a window titled "Removable Drives and Media Preferences" and un-check the "Mount removable media when inserted" and the "Burn a CD or DVD when a blank disk is inserted" so that I can work with rewritable CD/DVD media the way I want.

What is on the drive? If it's something critica, such as your /home or /etc directory, then of course the system won't make it to runlevel 5 without it.

Also bear in mine the boot order in your machines BIOS settings.

We seem to be talking about 2 different uses for the USB drive.
Do you want to boot a Linux system from the USB stick, or do you want to mount the USB drive after the system is up?
Kind Regards,
Keith

Folks, thank you very much for the advice. I am using the disk for system backup and then putting it in a safe. It does not have to boot the system. I did find that changing the last element of the line in fstab from 2 to 0 cured my immediate problem: the machine now boots properly without the drive physically attached.
Again, thanks to all. What a great community!
ttfn, Dick
