Charles et al, For your info, I have nearly the exact same configuration and the identical result. I have the ACard 6280M and the Maxtor ATA 133, 40GB version. I use a PowerMac 7300 with a G4/400 ZIF upgrade, 896MB RAM, internal video with 4MB VRAM and OSX 10.1.5/OS 9.1. Each time I chose to load the OS 9 drivers using the OSX Drive Utility, the drive corrupts when rebooting in OS 9. If I chose not to load the OS 9 drivers using the OSX Drive Utility, the drive is fine in OSX and does not mount in OS 9, but it is fine again when rebooted in OSX. If I chose to try to format in OS 9 using the latest Apple Drive Setup, the formatting fails with an error code "Error message: assertion (!LocalError) failed in PatchWrite Driver.c" on line 64", and is useless. While the drive supports OSX alone, this anomaly is UNSAT. Reading the applicable database reports at xlr8yourmac.com, others have reported the same problem and it appears this is unique to this ACard part number and this ATA 133 series of Maxtor drives (all the same technology, but different capacities). By that I mean that the ACard supports other drives such as IBM fine, and the Maxtor ATA 133s run well using other ATA PCI cards. I also run an older Maxtor ATA 66/20GB off the ACard and it is flawless in both OS 9 and OSX. I have to assume that the flaw is something incompatible between the specific implementation of firmware between ACard and Maxtor.
I have tried for a couple months, and am still working this with Maxtor and ACard tech support. I believe these two need to communicate and get their act together. One or both should be able to develop a firmware update that will resolve this incompatibility, and that would be a better solution for both companies and the Mac user community than letting a basic incompatibility float forever and frustrate users. I am sending a copy of this to both the Maxtor and ACard technicians I have worked with and to xlr8yourmac.com. I will continue to press the issue, fully expect a response, support and resolution. Attached is a copy of a detailed e-mail thread on the subject. Forgive its length, but there is a volume of relevant information for those interested. If the list doesn't support the attachment, I will glad to send it to anyone who asks directly.
