what is the file type of fat32?

[hwang]

Hi,

my machine has debian system and i insert an usb external hard drive on it. the hard drive has been formated as fat32. but i can't mount it. the command i used is:
mount -t vfat /dev/sda /mnt/test
/mnt/test is the mounting point. the reply of debian is:

mount: wrong fs type, bad option, bad superblock on /dev/sda,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
what's wrong with my usb external hard drive? who can help me? thanks!

try mountig /dev/sda1

Hi, thank you for valuable suggestion! it works!

but i have a new question.

for my machine, mounting usb device is strange. my machine has two usb ports.

for usb memory, commond: mount /dev/sda1 mouting-point
for usb hard drive (fat32), command: mount /dev/sdb1 mounting-point
for usb hard drive (ext3), command: mount /dev/sdc mounting-point

no matter which usb port is used, only specified command works for specified device. it seems that different port of /dev/... is assigned to different usb devices.

do u know why? have a good day!

If you have (at least the first two) devices inserted into the usb port when you are starting up, or you insert them in that order, it may be due to the order they get recognized. Otherwise, I don't have a notion even, now.
