Mac OS X 10.4.6 Special Report: SCSI drives not recognized

Prioer to the release of Mac OS X 10.4.6, we reported a series of kernel panics when writing to or reading from some SCSI devices under Mac OS X 10.4.x.

The problem was usually solved by removing Adaptec 290X-2930.kext and other related files from the /System/Library/Extensions folder.

We've now received reports from readers indicating that Mac OS X 10.4.6 does not suffer from similar kernel panics -- but refuses to recognize SCSI drives that rely on these extensions altogether.

MacFixIt reader Gabriel Dorado writes:

"Mac OS X 10.4.6 Combo updater prevents kernel panics when extensions like '/System/Library/Extensions/Adaptec290X-2930.kext' are installed and an external QPS Dupe3 CD-R duplicator is connected via SCSI to an Adaptec 2930 Ultra SCSI card (AHA-2930CU) that came built-in a PowerMac G4/500 (AGP) purchased from the Apple Store . The bad news is that the external SCSI device is no longer recognized. So, instead of fixing the issue, Apple has decided to 'hide' it."
