usb drive woes

russianwizard · 2009-03-31 03:01:10

There are 2 problems I exsperience with usb drives on my arch install. 1st off ,when I mount a flash drive (fat16 /32) it is read only to everyone except root. Second off, sometimes I will get input output errors and files will start to corrupt.

for me the problem with usb external is due to motherboard mostly i believe.
have you tried other systems?

I experience the same problem with my Toshiba laptop. I get IO errors all the time.

For the ownership/permissions issue, use a fstab entry, or pmount, or hal-based automounting.

When you mount as root, root becomes the default owner. If you want a different owner or group, specify it at mount using options (-o) uid (user ID, a.k.a. owner) and gid (group ID). For example:

mount /dev/sda1 /media/usb -o uid=russianwizard,gid=users

Is there any way to solve i/o errors without a restart? Also how do I get usb devices to auto mount?

I'd suggest ivman for that

I'm going to add a modern pci usb card. I've tried a lot of things. Something about ICH4 and the loading of ehci_usb and/or uhci_usb and their order etc. My motherboard is old enough that with everything else i am learning it seems a unique waste of time to attempt to puzzle this out. Rare that i would say that it's not worth it. There just little to be gained for the future.

That said I'd love a fix.

On another note i learned SO many tips on hot to get old machines to boot by altering the grub menu list.
really amazing that was with new kernel, getting old old manhines to work.

heres another oddity I discovered. If I automount the device in thunar (under root) it mounts fine. But the rest of the system cannot access the drives. My permissions are really screwed up >.< I added my user to the proper groups and I still can't access / use usb devices properly. Here's my group file:

root::0:root
bin::1:root,bin,daemon
daemon::2:root,bin,daemon
sys::3:root,bin,michael
adm::4:root,daemon
tty::5:michael
disk::6:root
lp::7:daemon
mem::8:
kmem::9:
wheel::10:root,michael
