How do you mount a usb thumb drive?

stakhous · 09-15-2003, 09:40 AM

I'm running knoppix-std on a cd and I want to save my information onto my usb thumb drive. Does it have a /dev name?Ive read through a bunch of manual pages and found nothing.

thanks

your usb drive is probably /dev/sda1

on a usb drive, make sure you have sync in your options in fstab, so that the information is written to it immediately. if you don't and you pull the drive out, you might lose some data.

it says that sda isn't found in fstab. Do i manually put it in there?

Make a directory, let say /mnt/thmb by using the command mkdir /mnt/thumb. Then change the permmisions to read/write for everbody buy using the command chmod 777 /mnt/thumb. Then to mount the drive use the command mount -t vfat /dev/sda1 /mnt/thumb. That should mount the drive under the /mnt/thumb directory.

yes, you have to put it in your fstab. i can help you with that if you like.

Put this in your /etc/fstab. This will mount the drive with read/write permissions for everyone.

/dev/sda1 /mnt/thumb vfat uid=500,gid=500,umask=000,exec,dev,suid,rw 1 0

Thanks guys, worked without a hitch.

one question though.

Why is is sda1 and not sda0? or doesn't it matter

sclebo05 · 09-15-2003, 06:57 PM

good question, but i don't know the answer. here is the line from my fstab:

/dev/sda1 /mnt/pendrive vfat noauto,user,sync,rw 0 0

I have no idea, my USB zip drive is sda4. Go figure.

How do you find your device if you already have a /dev/sda1?

sclebo05 · 02-18-2004, 09:34 PM

trial and error my be the simplest way if you don't have too many devices.
/dev/sda1 , /dev/sdb1, /dev/sdc1 ......

linux orders devices in sequence. someone probably knows a way to check what is physically connected, but i always just tried each one till i found it

One thing to keep in mind is SCSI/SATA devices are mapped to /dev/sdxx as well. I'm not sure which pulls precedence over one another if you have both SCSI and SATA involved, but im willing to bet they both are mapped prior to the USB hub even being processed.

For example in my situation i have 1 SATA HD and a USB Thumb drive. My devices look like this:

/dev/sda1 - boot volume
/dev/sda2 - swap
/dev/sdb1 - thumb drive
