Are there any known problems with the packaged Advansys controller? What do I need to know about using this controller?
Rick Adams posted the following to Usenet about the Advansys SCSI host adapter: If you are using the HP supplied controller from Advansys be advised there are at least 2 revisions of the card. The one I first got was positively identified to produce random read errors when reading from the HP CD. This means that if I used the HP drive to read a CD, I occasionally had corrupted data during reading. Didn’t matter if the disk was a silver manufactured CD or a CD writer burnt CD. I was sometimes seeing as many as 10 bytes wrong in one whole disk read, to as few as 1 byte wrong in 30 CD reads. Yes this is a tiny error rate, but there should be absolutely no errors of this sort. This was traced down to be the cause of one CD I burnt that had two wrong bytes on it. That is, since the drive read in some wrong bytes, that’s what it wound up writing. The solution to the read error problem was to swap out the HP supplied controller card. The one that caused the read errors had the following chips
