Dantz says Adaptec SCSI cards do not function "reliably" under Mac OS X

Eric Ullman of Dantz' technical marketing team sent MacFixIt the following statement on Adaptec SCSI card compatibility:

"Ongoing testing by DantzLab has found that Adaptec SCSI cards do not function in a consistent, reliable manner when used with Mac OS X. These findings are supported by hundreds of reports from customers who have experienced problems with tape and CD-RW devices attached to Adaptec SCSI cards.

"The problem, which affects all versions of Mac OS X including 10.2 (Jaguar), is not application specific. Rather, incorrect data is passed by the SCSI card to and from any program communicating with a SCSI device. The result may simply be an inaccessible device, or worse, data corruption can occur.

"Adaptec has been made aware of this problem, and they are working on a solution. However, until this issue is resolved, Dantz can no longer recommend or support Adaptec SCSI adapters for use with Mac OS X. These adapters include the Adaptec 2906, 2930 (which is also the $49 Ultra SCSI card option with the Power Mac G4), 29160, 29160N, and 39160 SCSI controllers.

"When Adaptec releases new software drivers that provide reliablefunctionality in Mac OS X, we will reinstate support for Adaptec SCSI adapters at that time."
