i have a 1640 which i bought a few weeks back but have hardly used (been away).
it’s been working fine with the few discs that i’ve thrown at it, but today i was using it to install CoD2 off an original DVD, and when the drive spins up it makes this horrendous buzzing noise like something is grinding on something. it doesn’t seem to affect the drive’s ability to read the disc (everything installed fine), but it sounds awful. it also does it with the 2nd (bonus) CoD2 disc. both discs can be read perfectly (it seems), and they come out completely unscathed.
any ideas? i tried the disc in my lite-on dvd-rom and it sounded perfectly normal.
