Mmm... per quanto riguarda l'hard disk credo che fsck potrebbe fare al caso
tuo, cito un frammento della man page:
FSCK(8) FSCK(8)
NAME
fsck - check and repair a Linux file system
SYNOPSIS
fsck [ -AVRTNP ] [ -s ] [ -t fstype ] [ fs-options ]
filesys [ ... ]
DESCRIPTION
fsck is used to check and optionally repair a Linux file
system. filesys is either the device name (e.g.
/dev/hda1, /dev/sdb2) or the mount point (e.g. /, /usr,
/home) for the file system. If this invocation of fsck
has several filesystems on different physical disk drives
to check, then fsck will try to run them in parallel.
This reduces the total amount time it takes to check all
of the filesystems, since fsck takes advantage of the par
allelism of multiple disk spindles.
The exit code returned by fsck is the sum of the following
conditions:
0 - No errors
1 - File system errors corrected
2 - System should be rebooted
4 - File system errors left uncorrected
8 - Operational error
16 - Usage or syntax error
128 - Shared library error
The exit code returned when all file systems are checked
using the -A option is the bit-wise OR of the exit codes
for each file system that is checked.
In actuality, fsck is simply a front-end for the various
file system checkers (fsck.fstype) available under Linux.
The file system-specific checker is searched for in /sbin
first, then in /etc/fs and /etc, and finally in the direc
tories listed in the PATH environment variable. Please
see the file system-specific checker manual pages for fur
ther details.

Poi per ottimizzare il tuo hard disk potresti usare hdparm, naturalmente e'
ormai di rito: man hdparm ... :-)
Anche in Linux c'e' il "famigerato" defrag ma e' veramente poco usato
poiche', normalmente, la percentuale di frammentazione del filesystem, dopo
diverso tempo, si assesta sul 5% e ci rimane ancora per molto tempo ...
Comunque, riguardo l'uso di defrag consigliano sempre di fare un backup e
quindi e' indispensabile un bel man defrag .... :-)
