[gentoo-user] external USB harddrive

[gentoo-user] external USB harddrive

[James Lockie]

Does anyone have one of these? :-)
It mounts when I connect it but a user can't unmount it.
My USB memory stick and USB card reader work fine.
It is only the hard drive that I can't unmount as a user.
I don't have or want an /etc/fstab entry for it, I should be able to 
configure KDE to handle it.

You may need to add it to /etc/pmount.allow, as described in man pmount.

These are the packages that would be merged, in order:

Maybe not "needed", but highly "recommended", at least by me.  I
suggest merging it.

Ok, so how are you mounting the drive under KDE?  ivman?

I would add it to fstab (I reckon this would be the easiest way) - the same fstab entry should work for USB memory sticks/card readers as well, to my knowledge.

Or if you wanted to get really fancy I believe you could write a udev rule so it recognises that device and assigns it /dev/externalhdd or the like :)

I tried creating 10-my-udev.rules

but then KDE doesn't see the new drive.

So it mounts fine, but you can't unmount it?  I've seen this happen,
and fixed it by telling konqueror not to keep any instances
pre-loaded.  The problem seems to be that if you browse the drive
using konqueror, it chdir()'s to the drive, and stays there, so any
attempts to unmount it report "busy".

That was so once. Haven't had any such trouble lately (KDE 3.5.5). Anyway, 
don't you think James would run into the same problem with memory sticks? He 
explicitly states above that it only occurs with his drive.

That said, I don't know what causes this behaviour. ;-(

It definitely used to be caused by pmount, which automatically mounts and
unmounts removable devices but not hard disks, unless they are
whitelisted in /etc/pmount.allow. Although it should apply to both
mounting and unmounting.
