Charlie, Guess I have to retract my previous statement about BlitzDisk working with jdisk.device – turns out I started getting many read/write errors walking a large directory on my jdisk-ed hard disk (first using the ARP file requester, but later repeatable with other directory programs). The problem(s) went away after terminating BlitzDisk. Speculating, I'd suspect that there's some strange timing requirements that are getting thrown off by BlitzDisk's intercepting of the i/o requests. Too bad, cause I was hoping that it would work with that hard drive also. The program works great with a SCSI drive connected to the 2090, though. I did a preliminary test with saf-T-net, backing up a single directory from my (cached) SCSI drive, with caching also enabled for trackdisk.device, and did not encounter any problems. The results are not substantial enough to guarentee that folks won't encounter any problems, but are encouraging. If only I had enough time (and disks) to do full backups/restores and really test out the sucker (I'd need two backups and _hopefully_ one full restore), but I don't have 3 hours of downtime available for that drive right now. Hopefully later this week I'll be able to find the time. ..Bob
