compile ton kernel 'h compile se kati allo vari.
Episeis deite ti mou elege to hdparm

[root /home/paul]# /sbin/hdparm -t /dev/hde

/dev/hde:
 Timing buffered disk reads:  64 MB in  8.68 seconds =  7.37 MB/sec

exwntas dwsei prohgoumenos

[root /home/paul]# /sbin/hdparm -c 1 -d 1 -K 1 /dev/hde

/dev/hde:
 setting 32-bit I/O support flag to 1

Anepitrepta pragmata.

Psaxnw na vrw ena ipostirizete to chip afto kai vriskw pws stous 2.4.x
