Title: [solved] mount usb mp3-player
Post by: uggla on September 14, 2010, 04:02:40 PM

Hi!

I have an usb mp3-player that won't show up in fstab when doing sudo rebuildfstab. It shows up as /dev/sdb: UUID="68DE-5DE7" TYPE="vfat" when doing blkid. When doing sudo mount /dev/sdb /mnt/sdb i get "failed: Invalid argument". How can I mount it?

regards

Blind guessing, but it couldnt harm to do a fsck (dosfstools-*.tcz required)

Also you could try to specify fs with mount, e.g. -t vfat

It isn't in fstab because it isn't partitioned.
Just:
mkdir /mnt/work
mount /dev/sdb /mnt/work

Specifying the fs (vfat) solved it. Thanks!

In this case I would still do a fsck. Better safe than sorry.

I got this:

tc@box:~$ fsck /dev/sdb
fsck 1.41.11 (14-Mar-2010)
fsck: fsck.vfat: not found
fsck: Error 2 while executing fsck.vfat for /dev/sdb

what does that say?

Code: [Select]

dosfsck -vrf /dev/sdb
unmounted!

I got:

Then it's safe to use mount -t vfat?

Yeah, I couldn't see anything wrong.
