Good and bad observations:
When using a relative new 15 GByte hard drive (vendor IBM) with the wd0
driver the HD-led never turned off, even without disk activity.
With the ata driver the hard drive led works as expected. When running a
"make buildworld"
i had the impression that all went very fast. The ata driver claims to
use DMA ..
This was on my box at home ...
At work i cant get the ata driver to work with my ide-zip drive and
mtools. The box
has a scsi controller and the zip drive as master on wdc0
wdc0 at port 0x1f0-0x1f7 irq 14 on isa0
wdc0: unit 0 (atapi): <IOMEGA ZIP 100 \
ATAPI/23.D>, removable, intr, iordis
wfd0: medium type unknown (no disk)
wfd0: buggy Zip drive, 64-block transfer limit set
when the ata driver is active, i.e. "mdir z:" ("/dev/rafd0s4") leads to
ZIP drive
activity, but it fails on reading partition information (was also
mentioned earlier in
this group from others).
