Can't mount usb drive

esanchez · 10-06-2004, 06:08 PM

Hi everybody!
I'm trying to mount a usb drive in the followin way:

Code:

mount -t usbdevfs /dev/sda1 /mnt/usb

but the only thing I get in the /mnt/usb dir is:

Code:

root@midget:~# ls -la /mnt/usb
total 1
dr-xr-xr-x  1 root root   0 2004-10-06 17:16 ./
drwxr-xr-x  6 root root 144 2004-09-30 10:30 ../
dr-xr-xr-x  1 root root   0 2004-10-06 17:16 001/
-r--r--r--  1 root root   0 2004-10-06 17:16 devices
-r--r--r--  1 root root   0 2004-10-06 17:16 drivers

I have the modules usb-storage and usb-ohci loaded in the kernel.
As far as I know the usb drive is recognized by linux, I can see is
a JetFlash doing:

Code:

root@midget:~# cat /proc/scsi/scsi 
Attached devices: 
Host: scsi1 Channel: 00 Id: 00 Lun: 00
  Vendor: JetFlash Model: TS64MJF2B        Rev: 2.00
  Type:   Direct-Access                    ANSI SCSI revision: 02

I have read the linux-usb.org site and the guide listed there, but still cannot make
it work...
any help would be appreciated..
thanks in advance..
regards,
-eduardo s.m.

You probably want to use mount -t vfat /dev/sda1 /mnt/usb (if using a FAT32 Windows file system) to make it appear like an ordinary drive instead of a USB device filesystem.

In addition, you may also want to add an umask= option or a gid= option to make it fully accessible for your regular (non-root) user.

That didn't work either:

Code:

root@midget:~# mount -t vfat /dev/sda1 /mnt/usb
mount: /dev/sda1 is not a valid block device

any other thought?

tail you syslog when you plug the drive in and see if it assigns a /dev/sd? designation. For whatever the reason my camera is always /dev/sdb on my old laptop (even when there are no other SCSI or USB devices plugged in).

type ' fdisk -l ' to see if it is being seen and where which /dev it is located at.

esanchez · 10-06-2004, 07:24 PM

I if make fdisk -l this is the output:

Code:

Partition table entries are not in disk order

I've trying to mount each of the sda's partitions with the same result always...

Why so many partitions on a 65 meg drive. If it was me I would fdisk the drive under linux and create only one partition as vfat and go from there. Lot sa of info on fdisk and formatted the drive here.

esanchez · 10-10-2004, 10:44 AM

don't know why so many partitions, it seems the drive was formatted using WinXP, and mess with
the MBR of the drive.
I mounted the drive using:

Code:

mount -t vfat /dev/sda /mnt/usb

I know how to make only one partition on the drive, but how can I format it?

use mkdosfs

slackist · 10-10-2004, 10:39 PM

If you don't need to use it with XP then use cfdisk to delete the partitions one at a time, then write a new partition table for just one partition.

Be warned: I had this problem with a handy2 or something drive. After doing the above it worked great with Linux machines but everytime I put it in an XP machine XP reported that it was not formatted
