As much as I like the WD Black series your system is not equipped to handle the SATA III (6.0 Gb/s) I/O this drive has, your system is only SATA II (3.0 Gb/s).

You'll need to lower the SATA speed down to SATA I (1.5 Gb/s) via a jumper. A better choice here is getting a SATA II drive.

Thanks for your reply...

The jumper settings will lower it to 3gb/s according to wd instructions...

Its hard to find a good sata ii drive nowadays.


Double check, if the newer ones do that will work.
