post #1 of 1 Thread Starter  Okay, here's the thing. I recently
bought a new Hypersonic machine, customized... problems galore
at first, DVD-RW (Toshiba SD-R6472) didn't work, kept stalling
whenever I tried to install an OS. Great service, however.. I
called in, they sent a replacement drive, that didn't fix the
problem though it worked, and I called in again to send both
laptop and drive back. Within a week, I got a call that it was
fixed.. and when it arrived, the installation of Windows XP Pro
went perfectly. Now, the drive keeps vanishing from the list at
odd times, and goes invisible, the system can't find it. I have
checked the device manager, and it lists an unknown device,
located on the PCI standard ISA bridge, says drivers are not
installed for it. Does anyone have any ideas as to why the DVD-
RW drive keeps disabling itself, or registering as a CD-RW?
