Mounting USB storage devices

How do I go about adding a usb drive to Linux to make it as easily accessable as the cdrom, etc?

Plug it in and type dmesg and something like the following should be at the bottom:

Code:

usb 1-1.4: new full speed USB device using uhci_hcd and address 5

scsi0 : SCSI emulation for USB Mass Storage devices

usb-storage: device found at 5

usb-storage: waiting for device to settle before scanning

  Type:   Direct-Access                      ANSI SCSI revision: 02

SCSI device sda: 512000 512-byte hdwr sectors (262 MB)

sda: Write Protect is off

sda: assuming drive cache: write through

 sda: sda1

Attached scsi removable disk sda at scsi0, channel 0, id 0, lun 0

usb-storage: device scan complete

Then add a mountpoint, for instance: mkdir /pen
and set permissions with: chmod ug+rwx /pen and chgrp users /pen
to: ls -ld /pen
drwxrwx--- 2 root users 4096 Feb 28 16:35 /pen

Then add a line in /etc/fstab for it, for sda1 mine is:
/dev/sda1 /pen vfat noauto,users,exec,noatime,umask=000 0 0

You can then mount with: mount /pen
and unmount with: umount /pen
Add a desktop icon if you like.

Don't know what you mean by as easily accessible as the CDRom but this is the comman line I use to mount USB flashdrives on my FC3 system:

mount -a -t vfat /dev/sda1 /mnt/flashdisk -o user,exec,dev,suid,rw,umask=000

after creating the /mnt/flashdisk mountpoint, of course.

When I say easily accessable I am referring to how you can open your home directory and click on the cdrom icon.

Code:

I adeed this to /etc/fstab:

Code:

# /etc/fstab: static file system information.

#

# <file system> <mount point>   <type>  <options>       <dump>  <pass>

proc            /proc           proc    defaults        0       0

/dev/fd0        /media/floppy0  auto    rw,user,noauto  0       0

/dev/sda1       /pen            vfat    rw,user,noauto  0       0

I ran mount /pen:

Code:

# mount /pen

[mntent]: warning: no final newline at the end of /etc/fstab

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

laptop:/home/cokecan# Mutex destroy failure: Device or resource busy

ICE default IO error handler doing an exit(), pid = 28353, errno = 0

Forget about all that for right now. Plug your flashdrive in, open up your terminal and as root do:

Code:

cd /dev

Code:

ls | grep sd

You should see some results like sda, sdb, or sda1. There should only be one if you have one USB Mass Storage Device hooked up. If you already have a folder in your /mnt directory for where you would like to mount the drive, skip this next step, if not

Code:

mkdir /mnt/removable

Now for the command that will actually mount the drive.

Code:

mount /dev/sda(or whatever yours was called) /mnt/removable

If this doesn't work and you have a FAT32 partition on your flashdrive try,

Code:

mount -t vfat /dev/sda(or whatever yours was called) /mnt/removable

I have a usb drive and a usb mouse hooked up on my laptop. I got this while running

Code:

ls | grep sd

Code:

ptysd

sda

sda10

sda13

sda14

sda15

sda2

sda3

sda4

sda5

sda6

sda8

Code:

# mount /dev/sda1 /mnt/removable

mount: you must specify the filesystem type

Code:

# mount -t vfat /dev/sda1 /mnt/removable

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

From looking at your dmesg, I would say that this isn't a mount problem. After you plug in your usb flashdrive, the last few lines in dmesg should tell whether the drive is sda1 or whatever. Unless you didn't copy all of the dmesg pertaining to the flashdrive. Find out what the device is and then we can work on moutning it.

That is everything from the beginning where it first mentions the USB device

What happens when you do a

Code:

mount -t vfat /dev/sda /mnt/removable(or where ever you want it mounted)?

From looking at your dmesg, sda is your flashdrive, not sda1, so again try

Code:

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

Do you know if your filesystem on the flashdrive is FAT32?
