gParted Help
I am using gParted to format a new USB (external) drive I purchased. It is a 320GB drive which "dmesg" sees no problem.
Code:
usb-storage: waiting for device to settle before scanning - EXT2 - EXT3 - Swap - Unformatted I do see in the format options list for FAT and others but they are greyed out and I can't select them for some strange reason. Am I missing something? I would like to format the drive as FAT so Linux and Windows can read the drive in case an emergency. Here is a screenshot |
Try using fdisk + mkfs. I have successfully formatted USB flash drives(which look like external drives) this way.

Sounds like another CHS geometry problem to me. Plus that drive is too big for a single FAT16 partition anyway, so I'd expect that option to be greyed out.
Anyway, FAT32 probably needs something like XXXXX/255/63 and Linux didn't see it that way. That's why I always initialize and create at least the first partition in Windows, just to make sure I get a good (cross-platform compatible) partition table written. Then I do all my formatting and adjusting of partition sizes with gparted. |

First, Code:
man fdisk, & As root, Code:
fdisk /dev/sdb use 'w' to write the partition table to the media. Repeat until all sectors used, or enough partitions created. Again, as root, Code:
mkfs -t vfat /dev/sdb1 I forget the maximum size of fat32 partitions, but as Crito mentions, you may bump into that limit. After creating the filesystem(s), they can be mounted, using mount. |
My only problem is in "fdisk", I don't know how to use all the available disk space. I know I can do +320000M for 320GB drive but drives are always less than advertised. Is there no way in fdisk to use all available space in one partition?

Well, my fdisk first queries for a beginning cylinder number (default=1), and then for a ending cylinder number (defualt=last cyl.). If you want, you can use the 'p' command to print the disk geometry for you.
