Re: DLT Tape Read errors on aac0
Scott Long schrieb: First of all, let me apologize for the mess that is the aac passthrough driver. I wrote it in hopes that it would be useful, but the support needed for it in the aac firmware simply isn't robust enough for the kind of SCSI stuff that FreeBSD does. In other words, it's a hack from top to bottom, and really is little more than a novelty at this point. See below... Christian Gründemann wrote: Waah, I forgot the most important information.

Christian I have a DLT drive here that I could probably hook up and start debugging with, but there are a lot of other things on my plate with higher priority, unfortunately. Your best bet for now is to put the tape drive onto a real Symbios or Adaptec SCSI card. Scott Thanks for your fast answer, Scott! What Adaptec Card
