FYI- The latest Issue of Maximum PC (Sept) is reporting a performance issue under XP with SCSI drives. The problem seems related to historic recommendations of the mode that a file should be opened with. There was a mention that under certain conditions, this problem could occur in W2K also. MS is supposedly working on a patch for it.
I've got 98 and IDE myself, so I wasn't paying full attention. ---Phil MD> You should invest in SCSI I/O if you have a lot of throughput problems to MD> cause buffer underruns.
