Oops.
It did have the effect of setting the SATA speed to 1.5 rather
then 3.0
on boot though.
Yeah, that was the intention. I'm running out of ideas. Just some
random suggestions...
* if you have access to different types of disks, try them.
* if you can open the storage box, take out the PMP and connect it and
the harddrive to a different power supply and see whether that changes
anything.
Hi Tejun,
I have some interesting results.
I had a pair of Seagate 250 GB SATA disks (models below) and tried
those out rather then the WD's. At the 1.5 gbps rather they appear
to work just fine both being on the same PMP, at 3.0 gbps they
timeout just like the other disks did. Possibly, the code isn't
detecting the max rate of the disks correctly since these drives only
do 1.5 and it attempted to do 3.0 gbps?
Have you found that drives can be picky if they will work or not with
PMP ports?
I'll be trying to get a bunch of different drives to replace the ones
that don't work with PMP.
Thanks,
Rusty
