USB Flash

DebianUser · 06-20-2010, 03:26 AM

I've recently bought a new USB flash drive and would like to use it on my linux box running 2.6.26-2-686.

Please could someone help me to get it working and also how to format it as fat32. Also I assume it has some sort of kingston software pre installed on it but i'd like to get rid of this and have 1 partition.

When I plug it in I get..

usb 4-7.4: new high speed USB device using ehci_hcd and address 11

you can fat32 format it with gparted.

thanks, do I do that or mount first as it's showing as sdc & sdc1

If you have the live cd of geparted format it first.

Alas I don't could you give me step by step guide?

Do you have the live cd yes or no ?
If not download it , and burn it as iso 9660, file .
It is freeware .
Start you computer with the live cd in you're cd or dvd drive .
And geparted will guide you

If you're seeing sdc and sdc1, then you've already got a partition on the flash drive. To
see what you've got, enter the following in a terminal window:

Code:

df -t

Why use a Live CD?

Why for me I find easy to use the live cd to format ore make some more partition on a drive when I am using my linux box.
But it is just my opinion .

sdc is the device
sdc1 is the partition

To format it with FAT32, all you have to do is:

Code:

mkfs.vfat -F 32 /dev/sdc1

I believe that will only provide the required information if the file system is mounted.

The device may already have a file system on it. You can find out with file -s /dev/sdc1. Here's an example with the useful info in green (scroll right to show it)

Code:

root@CW8:~# file -s /dev/sdc1
/dev/sdc1: x86 boot sector, SYSLINUX bootloader (3.11), code offset 0x58, OEM-ID " mkdosfs", sectors/cluster 8, Media descriptor 0xf8, heads 248, sectors 15683458 (volumes > 32 MB) , FAT (32 bit), sectors/FAT 15286, serial number 0x4c0659b0, label: "USBSLACKINS"

EDIT:

Or the blkid command:

Code:

root@CW8:~# blkid
[snip]
/dev/sdc1: LABEL="USBSLACKINS" UUID="4C06-59B0" TYPE="vfat"

Right I managed to format it using fdisk and it now shows

Disk /dev/sdc: 4002 MB, 4002910208 bytes
124 heads, 62 sectors/track, 1016 cylinders
Units = cylinders of 7688 * 512 = 3936256 bytes
Disk identifier: 0x274467ad

Device Boot Start End Blocks Id System
/dev/sdc1 * 1 1016 3905473 b W95 FAT32

cd /mnt/
mkdir usbflash
mount /dev/sdc1 /mnt/usbflash

How to I now write files to the flash drive?

MTK358 · 06-22-2010, 02:38 PM

fdisk doesn't format, it just partitions.

DebianUser · 06-22-2010, 02:53 PM

ok I unmounted it and did

mkdosfs -F 32 -I /dev/sdc1

is this right?
