Help with Sata !
Bon j'ai un vieux problème qui traine là :
/dev/sda:
Timing cached reads: 1516 MB in 2.00 seconds = 756.98 MB/sec
Timing buffered disk reads: 6 MB in 3.12 seconds = 1.92 MB/sec
C'est un peu lent !!!
Mais quand je fais :
bob@bob-main:~$ sudo hdparm -c1 -d1 /dev/sda > code
HDIO_SET_32BIT failed: Invalid argument
HDIO_SET_DMA failed: Inappropriate ioctl for device
Voili voilou que faire ? Suis je une brelle avec le sata ? le fait que le disque soit légérement bousillé peut etre la source du pb ? (il a bcp du mal des fois sous windows (freeze) depuis une coupure de courant)
