Intech Promises Cure for B&W Rev 1 HD Data Corruption: I'd commented last year that Intech's HD drivers solved the WD Expert corruption issues I saw in a rev 1 B&W G3. Their VP or Engineering replied to the the recent news post on the issue by saying their drivers should be able to address any master/slave corruption using their adjustable driver modes:
Here's a comment received after this article was posted on the Intech drivers solving the problem with the IBM 22GB drive:
"About the IMB Deskstar 22gig drive.
A reader comments that even when used as a master drive (one drive only) the IBM 22GB Deskstar has data corruption problems with the rev 1's IDE chip. I saw data corruption as noted in my B&W G3 Rev 1 Slave drive article with WD Expert drives but never tested an IBM drive. Maxtor's seem to be the safest bet, (based on feedback) but only a test will show if there are problems with any drive. Mounting large Apple .smi files like the OS 8.5.1 update (30MB+) are a good test to check for errors. As noted in the FAQ Apple G3 topic area question on the issue of rev 1 B&W G3s, Intech's HDtools driver set to reduced DMA modes may solve the problem, but again only tests can tell. (See the FAQ's Apple G3 section questions on 'What are the safest choices for drives?' and 'Are there any solutions for the rev 1 B&W G3 data corruption issues with IDE Slave drives?'). Of course adding a PCI IDE card will also solve the problem, but like a driver change, it also requires reformatting the disks.
Officially the rev 1's IDE chip did not support slaves, but it should support larger drives. If you've used an IBM or other large drive in your B&W G3 rev 1 please let me know your experiences and include details on the drive and disk drivers used.
How Do I Tell if my B&W G3 is a Rev 1? If in doubt that your B&W G3 is a rev 1 - see if it has the features of the Rev 2 models. (The most critical for this issue is the IDE controller chip part number.)
