I had some probs with lost clusters on my FAT formatted /hdd3 and repaired them using fsck.vfat.
I decided to try Diskeeper 7.0 on Windows to defrag my /hdd3 thru USB. (This was mentioned in another post).
Is this advisable? This is the first I've used Diskeeper on my /hdd3

What is the Linux counterpart to Defrag for a FAT partition?
I would rather use a Linux tool, instead of hooking my Z up to Windows to defrag the drive.
Below are before and after screenshots of Diskeeper.
This took about 1 hour.

It should be fine. Just takes longer. And don't unplug it while you are defragging.

Thank you for your reply.
What is the Linux equivelent for defrag?
How do people defrag a FAT partition on Linux, without access to a Windows box?

Yes, I know defrag shouldn't be interrupted. I would not unplug the USB cable while defragging over USB

Linux doesn't need defrag. So there aren't really any usefull ones out there. The best way to defrag a fat partition is to just use windows defrag.

Linux doesn't lead defrag for most Linux-native partitions (notibly ext2 and ext3).

However, FAT is FAT.. even when run under Linux it could benefit from defragging couldn't it?

I don't know of any tools offhand. I stopped using FAT up until last week when I got a C1000. =/

Correct. And the only reason someone would still use FAT is if they have a Windows operating system that needs it. In that case they can just use windows defrag to defrag it.

on linux, simply back everything up, erase, restore.. the only time I use fat is for inter-changing files between windows and linux.

there are utilities for windows to read/write ext2 partitions.
