This is not strictly true. [snip] So, to deal with the "AV" crowd, whose hardware often can't handle being starved of data for several hundred ms, drive manufacturers made the recalibration process interruptible, so that data operations continue and recalibration occurs in the "background". I thought that most SCSI devices released the bus during the entire seek process, which was one of the advantages of SCSI over IDE to begin with. Am I mistaken?
