My computer just had a hiccup.
I tried booting it up. The BIOS seemed to take a long time to recognize my SATA drive (Western Digital Caviar Black 160GB 3Gb/s,) and actually booting from it was impossible. So, I tried unplugging my IDE drive (this has worked before in the past,) then, instead of telling me my DVD Writer was a TSSTDVDWritemaster, it told me it was a SonyATAPICdROM. It didn't even recognize anything but the supposed Sony CD-ROM drive. I was at wits end. I tried all the SATA power connectors on my PSU, all the SATA connectors on my mobo, it just would not work. I figured it was a goner, so I wanted my brother to test my WD drive to ensure my data was safe.
I literally do not know how I fixed it, but apparently making the DVD writer on the secondary IDE channel made it work (still recognized as a Sony CD-ROM drive.)
This has been about the third time this has happened to me. Curse you to hell, M2V.
