DVD Drive cannot read DVD



I am using W2k until last week for years now and my Sony DVD RW DW-Q30a is perfectly working w/o problem. My computer just boot unexpectedly in the middle while updating windows (ActiveX). I can no longer start W2k for many days so decided to reformat my hard drive and started to setup WinXP. My dvd drive now is not reading dvd and cd and keeps “not responding” if I click D: although I can see it in the Explorer and even see the content but cannot read or copy. This drive can be seen also in the hardware device with a driver YY6. Reinstalling YY6 or YY7 is only telling me “unable to flash firmware… contact… vendor”. Tried mkflash, flashfix and so on… and still won’t work. Kindly help me- Thanks
