I'm having problems getting my new Toshiba 3401E (external) to work right. The current problem is that it won't let me access subdirectories on the CD-ROM disks if they are more than one level below the root directory, and it won't let me go back up to the root directory. Needless to say, this has also caused several programs not to run. Here's what I'm running: Controller – Always IN2000 with most recent EPROM and ROM, I have tried it both terminated and not, with no real difference in results. Hard Drive – internal Maxtor 210M SCSI drive, SCSI ID 0, terminated. External Toshiba 3401E connected with Macintosh (grey) SCSI cable, terminated externally both with plug on unused port and pass-through plug on port in use (have tried with one or the other, no difference in results), not terminated internally. MSCDEX – version 2.22. DOS version 6 (had same problem prior to upgrade). Currently using CDROM.SYS. I wanted to use Corel SCSI and their ASPI driver, but Corel doesn't recognize the existence of the CD-ROM drive when it scans the SCSI bus. Any ideas anyone? My best guess is that I have a defective CDROM drive. The people at Always and Corel failed to figure out why the ASPI driver keeps the CDROM from showing up on the scan of the SCSI bus, and now I'm having this even more fundamental problem. Thanks in advance for any ideas!
