My toshiba sd-r5002 wont recognize ANY blank dvd-r

[memyself]

My toshiba sd-r5002 wont recognize ANY blank dvd-r, it recognizes everything else............blank cds, burned cds and dvds burned before this problem started. I think I have tried everything (at least I think so) can it really be the toshiba that have retired ??

UPDATE:
When running "DVDinfopro" it recognizes the dvd fine, which leaves me with the conclusion that the drive must be ok and the problem must be in windows.............
