Hi there, hope someone can help, I'm having problems with my drive, it won't read blank dvd-r/rw's, It's fine when it comes to regular discs with data on them, it just keeps telling me to insert a blank disc even though there's one in there. The number of the disc drive is WDC-WD400BB-00DEA0 (IF ITS ANY HELP) I was wondering if there was any updates I could use?
