Can't mount usb drive


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?
regards,

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.

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.

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?
regards,
-eduardo s.m.

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
