18 My brother has windoze XP and NTFS. It gets very fragmented. He
19 defrags that thing pretty regular. I would think that NTFS may be
20 better than *FAT but it doesn't seem to be much.

35 I have to say, my system is pretty snappy. I have a AMD 2500+ with 2Gbs
36 of ram. My drives are the bottle neck but I can't say that it is
37 because of it being fragmented. It is a ATA133 system but one drive
38 runs ATA100 if I recall correctly. May be that one drive is older than
39 the other.

41 Frag check is a script that someone wrote. It is not part of reiserfs
42 tools or anything. I'm not even sure how accurate it is with reiserfs
43 or if the file system matters.
