Recently installed an NEC 3500A DVD/RW, no appearant problems.
Used it in Alcohol 120 and burned a backup of a PS2 DVD.
Put DVD movies in and they play.
Tonight I try copy some large (1-3 Gb) sized files to it.
1st thing noticed is that in the file sub-menu if select Send To then the follow on menu shows the DVD drive but not the CD-RW drive.
2nd thing noticed, once I put in a blank DVD (Philips DVD+R 1-8X 4.7Gb, listed as supported by this drive on the NEC site) the icon for the drive changes from DVD to CD. Any attempt to copy a large (1-3 Gb) file to the drive using the Paste command comes up with a Drive Inaccesible (at first) and then a Problem Copying, Retry/Cancel window.
Remove the blank DVD and the icon changes back to DVD.
