My internal SATA disk is starting to show errors (it's a 250GB Maxtor) and it fails the Apple extended diagnostic test with an error code 2STF/8/3.

I'm assuming that means it's time for a new disk. I was going to get a WD400KD but I noticed this report of an incompatibility with Apple G5 tower:
http://wdc.custhelp.com/cgi-bin/wdc.cfg/php/enduser/std_adp.php?p_faqid=1415

And also this report, indicating an incompatibility between that drive and Broadcom 5770 controllers:
linky

My iMac identifies the SATA controller as a Broadcom K2.

So is that the same as the 5770? Does anyone know if this disk will work okay in an iMac G5 or not? Or have a recommendation on what I should get instead?

Thanks,

A quick google search found this:

Hope it helps.

Thanks, Jose, but that's essentially the same information that I linked to.

At least some versions of the G5 tower are affected by that problem. My question was if anyone knew if the iMac uses the same Broadcom SATA controller.

Western Digital says there is a problem with Broadcom 5570 SATA controllers, but I can't figure out if that's the one in my iMac. An lspci identifies it as a Broadcom K2. Does anyone know if that's the same one as in the G5 towers?

Cheers,
Jaeger

ServerWorks Frodo / Apple K2 / Broadcom chip — libata's sata_svw driver provides product-level support a/o 2005-11. As of 2004-07-08, that driver supports the Apple K2 and ServerWorks Frodo4 (4-port) / Frodo8 (8-port) variants. Other variants' PCI IDs haven't yet been collected, added to the driver, and tested. The Broadcom chip used appears not to be model BCM5770, so Broadcom's proprietary "bcraid" driver likely won't work. (Broadcom acquired ServerWorks in 2001.)


Okay, so the chip in your machine *isn't* a bcm5770. Searching around some more, however, shows this:
http://ozlabs.org/pipermail/linuxppc64-dev/2005-November/006817.html - lspci on PowerMac9,1
http://www.ubuntuforums.org/showthread.php?t=43662 - Unknown PowerMac G5 (Serverworks == K2-sata)
http://www.usenetlinux.com/showthread.php?t=234650 - Unknown PowerMac G5 (Serverworks == K2-sata)

So... I'd guess that they're the same controller.

Yeah, I'd guess you're right - it certainly looks like the same as an lscpi on my machine.

The WD drive was recommended at SilentPCReview as a cool and quiet drive - which is exactly what I wanted in my iMac, but obviously not if data integrity is sacrificed.
