I have a 24x CDROM drive shipped by Creative Labs which appears as * SAMSUNG CD-ROM SCR-2431 * on the System properties of Windows 95
When I leave a disk inside the drive idle for a while then the drive starts to work and the operating system gets locked for several seconds. Sometimes even the mouse pointer gets stopped. After that delay, everything works "fine" again.
Well I put an audio CD-ROM on the drive. I listen to it for a while and then when I don't want to hear it I simply click stop on the cd-player and close the cd-player. I don't have to remove the CD from the drive as I don't need to remove the Zip from the Zip drive or the diskette from its drive. Then, after a few minutes, the cd starts doing something by itself and my system freezes for some seconds. Simply it sets me up.
Also if my brother leaves a CD on the drive when he stops the machine I find same problem after a while of working, doing nothing with the CD.
You can abort the delay by manually ejecting the disc, removing it from the drive and closing it again.
It happens both with audio CDs and data CDs.
Please ask me if you need more details.
I have 486DX4/100, 40Mb RAM, APM turned off.
The CD-ROM drive is alone on secondary IDE as MASTER.
I have the auto-insert options disabled, both from the drive properties and from tweak-UI control-pannel add-on.
Thank you for your time.
