Western Digital note on WD4000KD/YR, WD1500AHFD/ADFD Drives and onboard G5 SATA 2 Readers with Raptor 150GB drive problems sent a link to a Western Digital tech note on compatibility with that drive and the WD4000KD/YR models and the onboard G5 SATA:
(UPDATE - as of fall 2006 WD has revised the Tech note to include 36/74GB Raptor models (WD360ADFD, WD7400ADFD) - copy below updated to include the latest copy as of Nov. 2006)
"Is my Apple G5 Tower compatible with the WD4000YR, WD4000KD, WD740ADFD, WD360ADFD, WD1500AHFD, and WD1500ADFD hard drives?
Answer:
Problem:
After installing a WD4000YR, WD4000KD, WD360ADFD, WD7400ADFD, WD1500AHFD, or WD1500ADFD, the computer system will hang (lock up), necessitating a system re-boot.
Cause:
The Apple G5 tower does not support certain standard Serial ATA interface protocols used by the WD4000YR, WD4000KD, WD360ADFD, WD7400ADFD, WD1500AHFD, and WD1500ADFD hard drives resulting in an interface lock-up. This causes the computer system to hang.
Resolution:
The only work-around we have identified at this time is installing a SATA Host Bus Adapter (controller card), effectively circumventing the on-board interface."
One of the previous reports below has a note about a jumper setting to limit the drive to SATA1, but most users say that isn't a solution to the problem.
BTW - This WD drive issue is -not- related to SSC being enabled. (SSC is Spread Spectrum Clocking, used to reduce EMI. See this EETimes article - SSC enabled drives have been reported as incompatible with onboard G5 SATA and some (often 4-port) Mac PCI SATA controller cards also. Although Sonnet notes their SATA cards are SSC compatible, earlier this year I posted info from Firmtek on some of their PCI SATA cards (4-port models) and compatibility problems with SATA (SerialATA) drives that had SSC enabled. Firmtek added this info at the bottom on some of their PCI SATA card product pages like the 4-port SeriTek/1VE4 and FirmTek SeriTek/1VE2+2. The 2-port models should be SSC compatible. Jeff at FWdepot send a mail with an updated list of compatible drives (i.e. with SSC disabled in Nov. 9th, 2005 news page. Also there are reports that current Seagate 7200.9 SATA drives have SSC enabled - so buyer beware. Search the drive database here for reports from G5 owners on Hard Drives before buying.)
Also,verkauf die Platte oder kauf Dir nen Controller.
