Hello! I have a ASUS DRW-24B1ST and it worked great when I bought it for my new comp. Then last night when I shut the whole thing down for a nights rest and woke the next morning, there was a problem. The cd/dvd drive was no longer visible under Computer. I opened device manager and it's under the drive section with a yellow triangle and an exclamation mark near it. I tried updating the drivers but it says everythings up to date. I downloaded the drivers manually but both give me errors, and I even downloaded a program called "Mats_Run.dvd" to help identify and fix the problem. It found the problem and also, could not fix it.
I'm stumped, this just randomly happened when I booted the next day. The drive can open and everything, it's just unusuable.
Like I said, I downloaded the drivers manually, but I don't know where to place them. The first one I run is "ASUSDOS" which when I open it, CMD prompt comes up saying "C:\Drive\Desktop\DRW-24~1.03\ASUSDOS.EXE - This system does not support fullscreen mode. Choose 'Close; to terminate the apllication."
The second file is ASUSWIN, which when opened says "No matched driver detected ! This utility is only for ASUS DRW-24B1ST drive. Detected drives:"
Just thought I'd provide anything else to help get this resolved as soon as possible.
Alright, now I'm completely puzzled. I removed the device and put in an old reliable IDE one that I had for a few years. I booted it up, and literally got the same exact error.
I'm simply flustered. I hope it isn't the motherboard, or any other hard ware that is making this happen. I'm at a loss, both cd drives do not work, saying there was an error while installing the drivers.
There is a step by step guide in that link on how to delete the upper and lower filters. It's a little different for each version of windows, so make sure you follow the guide for your version.
Thank you! You also helped me. Same problem Windows-7 64-bit, same drive mysteriously disappeared in My Computer and showed yellow exclamation point in device manager. UpperFilter showed 'Gear____" (something like that). I also had a lower filter. Deleted both, rebooted and drive is back online and showing! I wonder what I installed that did it. I didn't notice for about a month, as I rolled back system restore as far as it would go (May 12th 2012) and it did not solve the problem, so it must have been something I installed in April. I don't recall what it was, but thank you!
