I purchased a 17" Macbook Pro last June and a few days after the warranty expired the hard drive crapped out on me. I've been looking for a replacement and came up with the WD 2.5" Scorpio Black, 500GB, SATA 3Gbps, 7200 RPM, 16MB HDD. I've heard nothing but good news for this particular model except for some possible firmware issues. A lot of people seem to have severe issues (slow downs, lockups, unrecognizable disks, ect.) after upgrading the firmware. Does anyone know anything about this issues? Or have any comments on the HDD?
