Nodles: Thanks for your reply. It is already unchecked, yet all my history is gone.

Friends: I am running Windows XP Pro and everytime I run CCleaner all my history in RUN commands are deleted. Please tell me what I should leave unchecked to retain this history. Thank you.

I found if I unplug the power cord for 1 minute then reboot both drives appear as normal. I then created a restore point here. When I boot up normally and my second drive does its disappearing act I then do a System Restore to this point. Why this is working I have no idea, but it works. Only time will tell. Thanks guys.

I don't believe it is a hardware issue because if I switch the drives around, the original master now disappears and the original slave now appears. Also both drives appear in Safe mode. I changed cables umpteen times. ???????

Hazelnut, Andavari and Fieryone: Appreciate your responses folks. That's right, it disappears after a reboot without running CCleaner. By the way, what is dial-a-fix and how do I do it? It gets even more juicy because I find if I unplug the power cord for 1 minute during shut down and then reboot, all drives appear as normal. Weird stuff indeed!!!!!!!!!

Thanks for your replies guys. Both drives are brand new. Last time it happened I removed the CMOS battery and re-inserted after 1 minute. That fixed the problem until I ran CCleaner again last Thursday and it happened again. I tried the same trick but this time came up blank. Why this happens every time I run CCleaner beats me. I would be happy if I knew some Registry tweaks to "unhide" my drives. Thanks.

Friends: I am running a Pentium III computer, 650 MHz, 512MB RAM, Windows XP Pro. I have two 80 GB hard drives configured as master and slave. This is the second time I have noticed that after a CCleaner scan, my second hard drive has disappeared from My Computer and Control Panel, even though it shows up in BIOS. I have to do a System Restore to see it appear again, but when I shut down the computer and reboot, it disappears again. I imagined the first time was a co-incidence it happened, but the second time I ran CCleaner it happened again proves it is no co-incidence. Please advise what I can do to fix this problem. Thank you.
