Spinto dalla curiosità ho provato anch'io, ma i miei risultati, mi
sembrano un po' deludenti :(

Checksum: correct
/dev/hda:
Timing buffered disk reads: 64 MB in 3.95 seconds = 16.20 MB/sec
/dev/hda:
Timing buffer-cache reads: 128 MB in 2.11 seconds = 60.66 MB/sec
Questo dopo aver dato il comando:
hdparm -d1 -W1 -A1 -X69 -u1 -c3 -m16 /dev/hda
Confrontando i miei risultati con quello dei vostri portatili, il
secondo risultato è dimezzato.
Ci sono altri parametri che posso abilitare in sicurezza?
Inoltre, quella sezione finale "Security:" con la password e tutti gli
altri parametri, a che serve e come si abilita? Dove si trovano info a
riguardo?
