Mouting USB Flash Drive with RH 7.1

[Gabby James]

Hi All,

I have a USB flash drive which I was able to successfully mount under RH 
7.1.  Then I did a 'dd' command to copy a boot image file to the flash 
drive.  Now, I can't mount the flash drive.

If I try to mount the device I get the following message:
mount: wrong fs type, bad option, bad superblock on /dev/sda1, or too many 
mounted file systems.

This is the output of  cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
  Vendor: SanDisk  Model: Cruzer Mini      Rev: 0.1
  Type:   Direct-Access                    ANSI SCSI revision: 02

If I do a 'fdisk -l /dev/sda' it shows the the drive has one partition 
called /dev/sda1 wich is of type FAT16.

The line in my /etc/fstab file looks like the following
/dev/sda1		/mnt/usbkeychain	vfat    user,noauto,umask=0 0 0

When I do a lsmod, I see that the usb-storage module is currently loaded.  
So is usb-uhci and usbcore.

If I do a fdisk /dev/sda it just hangs.

Two questions:
1) What do I have to do to be able to mount my flash drive again?
2) Why did my 'dd' command break it?  How else can I copy an image file to 
the flash drive?

Thanks!
GJ
