I've got an LG GH22NS30 DVD writer & SONY CRX320EE(RYK1) combo drive. Last week I updated the firmware on the LG model to ver 2.0 but since then it become sluggish & now I can't read/write any sort of a CD/DVD on it. The other drive also doesn't seem to work for no reason after I switched to win7 from xp. Now :- 1) Is there anyway to check for driver or other software level errors before opening up the drive for repair ? Did the firmware update made that LG drive malfunction or is it some hardware trouble ? 2) Does an old drive like the SONY model(2005) not work with win7 OR it may have reached the end of its lifetime, anyway to check that ?
