[O/T] raptor 10000rpm ide disks
I just got a pair of WD raptor disks, which are SATA 10000rpm. Sweet, right?
No! They are connected to Asus A7N8X MB, which has SiI3112 Serial ATA
(according to dmesg).
hdparm -t shows TERRIBLE slow results.
/sbin/hdparm /dev/hde
/dev/hde:
multcount = 16 (on)
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 4500/255/63, sectors = 72303840, start = 0
OK, now try with DMA turned on. Locks up machine. Here's what was logged:
