I have a dv2000 with a MATSHITA DVD-RAM UJ-851S
Yesterday i was burning a dvd, it took about 2 hours but it wasnt burning so i finished the process and shut down.
Todat I inserted a cd to burn it but when i tried to access it trough Explorer it said: Cant get access to E:\. Incorrect Function
I have disable and enable it trough device manager but nothing seems no came
Soulh i reinstall driver or what can i do?
Thx in advance

EDIT: Now instead it says: Insert a disk into D:\ unit
Although i've already inserted the disk, the same problem happened with my card reader and i havent fixed it yet.
