I just ran a test, and the bug is > still there in 2.4.9-ac7. Maybe you're thinking of some other bug? OK, perhaps you are right. I received a credible report from Ed Tomlinson that the "reading the last block" bug is in 2.4.10. It seems that either I fixed something else with the same symptoms or I fixed it improperly. Unfortunately, I cannot reproduce it. By the way, why does everyone insist on using ide-tape? It seems to be broken beyond any repair by injection of lethal poison marked "OnStream Support" (not that it was brilliant before, but that was the last nail in the coffin). Just use ide-scsi and be done with it. I really do not enjoy reading ide-tape.c. -- Pete
