I've run into a customer of mine, who had their system taken to best buy's daunting ***** squad. The problem was simply he needed a wipe and reload done as his windows was seriously corrupt. The request for his information (specifically excel documents) to be backed up was noted, and the system went in. Much to this gentlemans surprise however, the system was returned with no information backed up, and the cd-rom and dvd r/rw not reading any discs. I immediately checked the device manager to see if the roms were at least being identified and recognized. They were, but with exclamations next to them advising a problem. Upon examining the two cd roms internally, I discovered one was set for cable select, and the other for slave. I then set the dvd rom for master, and the regular cd rom for slave. After restarting the machine, I expected that should have been a simple fix. However upon restarting the machine, there still are exclamations next to the drives under device manager. I am looking for any suggestions as to why this might be happening, as I am going back in the morning to re-visit this customer. I have 2 thoughts. 1: The ribbon cable simply needs to be replaced. or 2: Windows is corrupt in some manner. What do you think?
