Tips Harddisk di Linux

Untuk mengetahui partisi harddisk, gunakan perintah ‘fdisk -l’ sebagai superuser,

#fdisk -l

Device Boot Start End Blocks Id System
/dev/hda1 1 336 2698888+ 83 Linux
/dev/hda2 337 1320 7903980 83 Linux
/dev/hda3 1321 1429 875542+ 82 Linux swap
/dev/hda4 1430 3738 18547042+ 5 Extended
/dev/hda5 * 1430 1794 2931831 83 Linux
/dev/hda6 1795 3738 15615148+ 83 Linux

Mengukur Kecepatan Harddisk

#hdparm -Tt /dev/hdxx

contoh:

bash-3.1# hdparm -Tt /dev/hda1
/dev/hda1:
Timing cached reads: 246 MB in 2.01 seconds = 122.37 MB/sec
Timing buffered disk reads: 80 MB in 3.05 seconds = 26.21 MB/sec

Menghidupkan 32 bit I/O

#hdparm -c3 /dev/hdxx

Melakukan aktifitas Harddisk yang berat (Masking Interupt)

#hdparm -u1 /dev/hdxx

Multiple Transfers

#hdparm -m16 /dev/hdxx
