USB flashdrive not mounting

I have used many other distros from RH/FC, Mandriva, Ubuntu, knoppix and others and I have had no problem getting my USB flashdrive to work. If it has not worked from install then I've been able to tweak /etc/fstab and get the device mounted.

This is not working in Slackware 11 though (2.4.33.3 Kernel).

I have tried using:

Code:

/dev/sda1 /media/flashdrive auto defaults,users,noauto 0 0

and then

Code:

/dev/sda2 /media/flashdrive auto defaults,users,noauto 0 0

in /etc/fstab. This doesn't seem to work/mount.

Here is some output from a manual mount:

Code:

root@holly-desktop:~# mount -t auto /dev/sda2 /media/flashdrive

mount: /dev/sda2 is not a valid block device

root@holly-desktop:~# mount -t auto /dev/sda1 /media/flashdrive

mount: /dev/sda1 is not a valid block device

root@holly-desktop:~#

How does Slack recognise this device?

Also here is the (end part) output of dmesg:

Code:

hub.c: new USB device 00:07.4-2, assigned address 2

Try vfat instead of auto

I have this in fstab

/dev/sdc1 /media/flash vfat user,noauto,umask=0 0 0

I have found handling of flash drives more reliable in 2.6 than 2.4. The upgrade is simply a matter of installing packkages from /extras/ in the installation disc.

What does the command

Code:

fdisk -l

tell you about your USB flashdrive?

file system matters

Filesystem type(s): We'll assume that a USB device can have either a Linux ext3 or a DOS/Windows FAT filesystem. (You could've set the filesystem type to auto, but on certain systems this seems to prevent normal users from mounting USB devices with FAT filesystems. If you have the need to use a USB device with something other than ext3 and FAT, just add the type to the list – but it's rather unlikely you'll encounter anything like that.)

seems like the device is /dev/sda2,
first try $mount and c what all are mounted. since you have an entry in fstab you dont need to type all teh commands," mount /media/flashdrive " is enough. make sure /media/flashdrive exists.
after plugging in usb, do "rescan-scsi-bus -l "

please check my signature. also
