I own TI Travelmate 4000M 486 laptop and I have some problems with its SCSI Toshiba XM-4101TA CD-ROM.
It is reading original CD disks fine, for example Windows CDs, but there are some problems with burned disks. Some time ago I made a HDD backup and I would like to restore it with use of a burned CD-R, but when I put that disk inside the activity LED is just constantly lit, and MS-DOS is outputting drive error. I tried two brands of CD-R disks, one written at 4x and another at 10x, same symptoms.

An interesting thing is that I made a backup CD of original Windows 98 disk some time ago and it works correctly in that laptop, just like the original one (and that CD is identical brand as one of the disks I tried earlier) - so apparently it is possible to burn a disk that would work in such drive. I just made a direct copy of the original disk so maybe this causes better compatibility, does anyone know any methods or software which would help making custom data CDs compatible with the older drives? I tried slow burning speed and closing the session but it isn't enough. Maybe it is important which drive I am using to burn that CD?
