CD Drive not being recognized....sometimes.

I have a curious problem with a new CD drive...hoping that someone has a thought on how to proceed.

My new CD-R/RW drive (Samsung model SW-248F) is in a homebrew Win98SE machine...it worked fine when it was first installed, but after a few days, the machine (on boot-up) couldn't "see" the CD, so, of course, Windows couldn't see it either.  I flailed around making sure all my drivers were up to date and Win98SE was up to date.  Out of frustration I put back in an old CD drive and the machine had no problem recognizing the drive.  I put back in the new Samsung drive, and, voila, the machine recognized the drive.  

All went well until I turned-off the machine for a few hours, then the problem returned.  So I did the drive swap again, booted with the old CD, shut-down, replaced with the new CD, rebooted...and, voila, the machine recognized the new CD again.  

This process is how I now have to use the new drive!

I tested my motherboard's battery and it tested OK, but I installed a new one anyway.  No bios settings are being changed that I can see.  Does anyone have a thought about what could possibly be being reset that is causing the machine to not recognize the new CD on subsequent boot-up.

How bad are you straining your power supply?

If not that bad, then it sounds like you need a new 1

i had this problem when i had a 500mhz machine, 2 hd's big video card, lots o fans, 2 cd roms, etc..

On occasion something wouldnt work, then i would switch the connectors around and it would work...for a while..

Then i got a 350 watter and it ran fine 4ever :)

possibly the power supply, but more likely the burner itself, if your old CDROM still works.
maybe take your burner in to where you bought it,.. or return it on warenty to samsung

You may need a firmware upgrade for your drive.  Just make sure that the computer see's the drive before you do the upgrade.  This link should get you to the download area.

Check if you have a real time driver loaded in config.sys and autoexec.bat. Rem all lines loading driver. Actualy you shouldn't have anything in there (maybe path for wordperfect). Now check if you have Bus Master enabled in Device Manager. Try "no IDE channel enabled". If it helps leave Bus Master desabled for IDE where you have your CD drive.

If Bios cannot recognize your CD drive then you have a problem with cable or power. If it is power try to use power connector on wires not shared with hard drives, short and not run through additional connectors (no extention if possible). Check jumpers with a sticker. If using 80 strands IDE cable check motherboard doc for coloured plugs.

Thanks for your responses...I've got a software build cycle tonight, but I'm working on it on the side.  I've downloaded the latest firmware and am testing that.  The power supply is pretty new, but at 250w, should be enough since it is only a 450MHz motherboard, two 5400rpm HDD, one floppy, and this CD. I'll unplug the D: drive and floppy to test that theory.  Before that, though I will check the Bus Master...if I recall that area has had a checkered past...

I'll let you know.  Thanks once again.

I disconnected my 2nd HDD and FDD, and it came to life...I'll be heading out to buy a bigger power supply today.  Thanks to all who responded.
