How to Format a NTFS (USB) Hard Drive to FAT32 (or Ext3)?

How can I format my NTFS formatted USB hard drive (WD Passport 160 GB) to something that my Ubuntu 7.10 installation disc understands? I think I should format the hard drive to FAT32 or Ext3?

It has been my experience with Linux that when you install the OS it will do the formatting for you. See, if you have the HDD as free space and if it isn't you can delete any volume in has and it will set it to free space. Once you do that and then install Linux it should do all the formatting that you need as well as set up GRUB and any EXT that you will need. If you want to format it yourself as FAT32 for instance then go to the start menu(I am assuming that you are running XP) and find run, then type in CMD. Then you can type in FORMAT and go from there. If you need help with it try HELP FORMAT or you can try FDISK. If you want to delete a volume then go to RUN and try COMPUTER MANAGEMENT and find STORAGE. I hope that this helps some.

If you do not need/want any of the data on the USB drive make sure it is not mounted, then as root run the following command on the the device.

Code:

mkfs.ext3 /dev/sdX1

Replace X with the correct device. So if you only have one othrt drive connected to the system it will most likely be /dev/sdb1. Before running the command make sure the device you are referencing is the correct device. The command will erase all data on the drive.

Also, if you want it to be a FAT partition replace mkfs.ext3 with mkfs.vfat.

Hope this helps.

Unfortunately my Windows XP didn't recognize the hard drive (no "E:" icon appeared as does with my other USB hard drives) as it seems like Windows XP mainly understands NTFS, FAT and FAT32 formatted hard drives.

But the command

Code:

mkfs.ext3 /dev/sda1

solved the problem.

formating portable drive to ext3

Hi, I'm having the same trouble and I initially got stuck in that I couldn't find where my Ubuntu 7.04 had the plug-in drive. I couldn't see it on the mount table, so I issued

Code:

sudo fdisk -l

which produced, among other things,

Code:

  Disk /dev/sdb: 250.0 GB, 250059350016 bytes

  255 heads, 63 sectors/track, 30401 cylinders

  Units = cylinders of 16065 * 512 = 8225280 bytes

    Device Boot      Start        End      Blocks  Id  System

  /dev/sdb1              1      30401  244196001    7  HPFS/NTFS

Then I did

Code:

mkfs.ext3 /dev/sdb1

as suggested. I'll let you know if I get stuck again!
