OK, the situation where drives are found at SATA150 while drive and=20 controller both support SATA300 can have lots of reasons. If ATA states it has '300 support and the drive supports it as well=20 (note at least some early IBM/Hitachi drives was '300 but the firmware=20 set to '150 and needed a vendor supplied util to up it to '300) it=20 should work. However all kinds of interaction problems can make them=20 agree on the lower '150 speed, and ATA does not try to force anything=20 here, it just asks the drive/controller to connect at the highest speed=20 possible. As long as I dont support portmulitpliers the speed is not really an=20 issue, no drive (so far) on this planet can outrun even the SATA150=20 interface. On the ATAPI timeouts there not much to say, SATA ATAPI HW sucks jut as=20 much as ATAPI HW did it seems, the only way is to try and get it working = on as many as possible at the same time. That however means that someone = (usually me, you wont belive the ATAPI drive collection I've got here=20 already) needs to have all the drives available and time plus motivation = and needed skills to poke around to get it working. At least all the=20 controllers I have here in the lab and the two SATA ATAPI drives in same = work flawlessly... Sad but true. -S=F8ren > > Thank you for looking into these issues. NP! I try to get things fixed, but time has been limited lately... -S=F8ren
