I think it started after the sp2 upgrade.
I've been waiting awhile to see if this problem has happened to enough people so a quick fix can be made. I see a few complaints about this drive, but not exactly the same as mine.

It started one day when It wouldn't recognise a blank CD out of a stack I've been using for a while. I grabbed a RW disk, recognised it fine and burned it.

When I can get it to burn a cd. some of the files will be corrupt. Should I just slow my burning speed down?

It reads DVDs fine. reads CDs fine. just won't burn consistantly.

Oh yeah i just ran that devfilter thing and it gave me this

Upper - Redbook
Device object - Toshiba DVD Rom SD-2212
Lower Class Filter- PxHelp20
Lower Device Filter- imapi

My drive's firmware hasn't been updated it's Rev. 1013.

Any Ideas??
