I just made an interesting discovery, after *two years* with my Maxim
PC "Dream Machine Plus." I had built an x64 dream server with a Tyan
K8WE (S2895) motherboard, Dual Opteron 270s (all I could afford at the
time), 8 GB of memory, a *brand new, latest and greatest AMCC 3ware
9950 SE RAID controller, and four new Hitachi drives. This RAID
controller was one of the first RAID controllers on the market to
support SATA 2 naively.
At the time I originally installed the drives.I called Hitachi Global
Technologies technical support to make certain that the drives were
configured to run in SATA 2 mode. I was assured that they shipped as
SATA 2 drives. I proceeded to set up a RAID 5 array.
I had always had difficult with finding all four drives powering up
properly at boot, and I often had to rebuild my array. As I had a PC
Power & Cooling 1 KW power supply, I knew that power was *not* my
problem.
I just recently learned, by using the log on the controller, that the
drives were all running in SATA I mode. Hitachi had been *wrong.* I
had to use the "Hitachi Feature Tool" to individually change a setting
in *each* of the four drives to set them for SATA II. I was a bit
angry that (a) Hitachi had misled me and (b) it took me so long to
find out.
I am posting to this forum because other users may be unaware that
their "SATA 2" drives are actually running at SATA 1. Unless one
changes a setting in the drive's BIOS, the drive remains SATA 1.
Perhaps there is an easy way to know the SATA setting of the drive,
via some sort of Windows utility; but I did not know of one. In the
future I will always check in advance.
