Sorry if I'm a little off topic but I've been having a similar problem and would appreciate any help.
I have an ASUS CRW 4824a. The problem is as follows:
It will not read any cdr/rw media, whether recorded by this drive or others. I have a DVD-rom drive which CAN read and access these discs so I know they're ok.
For a while I could get NERO to write to media but it failed to verify (cannot read!!) When I played the media in the DVD-rom the files/data had been recorded!
I have tried un/re-installing the... NERO software/IDE drivers/both cdroms/updating the ASUS firmware v1.0, v1.1,v1.35.
I am using win98se and was wondering what specific registry entries relate to a drives ability to see cdr/cdrw, or in this threads case dvd+r. Anyone know?
