Attached is a collection of very useful CD-ROM disc drive and disc health check utilities. I extracted these from early version Nero discs. They are small .exe files that do not require installing any additional overhead, similar to installing and running CPU-Z. All are compatible with Win98se.

For me, they have been extremely useful to objectively compare operational condition and statistical data between multiple Plextor PX-760A drives running Win98se. With these, I have reliable data when troubleshooting and performing maintenance. (See attached images)
