I missed the original post, but FWIW, I have had some trouble with Adaptec 29320's. I have a Jetstor RAID-array which wont operate beyond U160 when talking to Adaptec, but will run at U320 when talking to an LSI-Logic adapter. This is identified by the manufacturer as an Adaptec problem, to do with 16byte CRDB's when using large logical-block-addresses. I've also had problems with DLT2 tapedrives on these Adaptec adapters, whereby unless I write records > 64K, records get dropped. There is no problem with DLT1. I've not yet had the chance to try the DLT2 drive on the LSI adapter. Terry.
