Harddrive perfomance

i have fedora 4 installed on a little laptop. i feel that the hard drive perfomance is not as good as it was. it is going slower than when i first installed fedora on it. i have two questoins regarding this issue :
1- i know that linux users don't like to use windows terminologies in here. but is there is anything similar to file system deferagment for linux ? is there a way to rearange the harddrive files. i installed / uninstalled a lot of packges.

2- i know that hdparm utility can enhance the hard drive perfomance but only if you know how to use it. the man page wasn't realy helpful or i wasn't to understand a lot of parts from that man page. can anybody give me a referance for how to use hdparm ???

thanks guys ..

Other small question

My hard drive is using dma so i think that's good. but i want to show u this output which i don't understand very well :

[root@FEDORA Apache]# /sbin/hdparm -Tt /dev/hda

Timing cached reads: 1508 MB in 2.00 seconds = 753.36 MB/sec
Timing buffered disk reads: 36 MB in 3.08 seconds = 11.69 MB/sec

does that mean that the transfer rate for the drive is 753.36 MB/sec ? is this rate good for a laptop ATA drive ? thanks ..

Yes that is the transfer rate . Note please that the more data your disk have the longer the time it takes for seeking the data and presented to you . So if your disk is quite full then you have better be thinking in getting a bigger one . Also , your RAM if increased it can improved the performance of your system

Caution: Do NOT set the -Y flag (capital Y) as this WILL shut down your hard drive and you will have to do a hard re-boot!!!!

For some reason, people don't realize exactly what happens when the -Y flag is set on a hard disk, especially IF the drive has "/" mounted on it!!!
