Alright,
I find that my system is slow and not as fast as usual.
After replacing a crashed HD, recompiled gentoo with the same make file as before.
MY laptop does complain about this hard drive not being suited for use (in my laptop)
But it states that i can continue at my own risk of data-loss.
Anyways here's an intresting error.
| Code: |
laptop kevin # hdparm -d /dev/sda
/dev/sda:
HDIO_GET_DMA failed: Inappropriate ioctl for device

Anon5710,
DMA is required on SATA or SCSI devices. You cannot turn it on/off.
If your /dev/sda is really a PATA device with the libata driver, DMA is on.
