Alan, I've found weird problems such as that when working with Unix or Windows NT with scsi drives. Make sure your terminating resistors on the drives are set up properly. If they are off in any way, they may work with simple OS's like dos, but not UNIX. The resistor problem often causes the machine to appear to write to the hard drive correctly, but the info actually never physically gets placed on the drive, the controller just returns a code of 0 for success. Some of these controllers do not recognize these problems correctly. The appearance that some of the data may be recorded and some may not can be the ghosty workings of scsi drives terminated improperly. Sometimes the cache will keep enough information in memory not sync'ed to appear fine everytime you look. But after a couple of megs have been saved, the os starts syncing the disks (but no data is saved) it goes to scsispace. Jeff -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= - Jeffrey D.
