This is such a weird thing. I have never come across it before and I would be very grateful if anyone can shed some light on what is going on.
I have an old Celeron 300A PC, with 48 Mb RAM, running Windows 98 First edition. I have put an LG CD-RWer into it in addition to the existing CD-ROM. I have double-checked that both drives are cabled, powered and jumpered correctly, but when I try to use either Cd drive Windows explorer crashes (explorer.exe). To be exact the CPU seems to go to 100% utilisation, and the the PC grinds to a halt. It doesn't matter whether it is a pressed (audio or game) CD or a blank CD-R/RW. The result is always the same.
I tried experimenting with the DMA settings, but it hasn't made any difference, whether DMA is on or off on either device. Interestingly I found that if I boot up with a disk in the drive I can then read from it, play audio and/or Read and write to it with the RW. Reasoning that it might not have enough power I upgraded the PSU to a 350W unit, but again this hasn't made any difference.
I have now taken the old CD-ROM drive out of the machine leaving just the RWer in there. Now it will read from the drive OK, but only one type of disk per Windows session. If the first disk that goes in is a CD-RW then I can use that type of disk Ok for the rest of the session. Put in an audio CD and crash, down goes explorer.exe again, 100% CPU and reboot time. The opposite is also true. If the first disk is an audio/game CD then that also is fine for the entire session, but if I want to use the CD-RW to burn a disk I have to reboot first.
Its almost like there is something wrong with the Auto-insert notification module of Windows, but I have never heard of anything like this before. Anyone out there can tell me what on earth is going on?
