I have had a 411S for some months and have successfully burned a number of DVDs, the last being a couple of months ago.
I am now having real difficulties with DVDs in the drive. It will read commercial DVDs, but refuses to recognise any DVDR media (blank or burned), including the disk which came with the drive.
I have made no hardware changes since it last worked.
I have checked that it is set to ‘Use DMA if available’
I have tried FS0F, FS0H and FS0J firmware
I have removed all burned related software, cleaned the registry and done a fresh install of the Sonic software which came with the drive
I have installed the latest Adaptec ASPI drivers
The burner has no problems with reading or burning CDs, only DVDs.
Can anybody please give me some clues as to what could be causing this. I am running Win XP sp1 and am using Mirror Platinum 4x DVD+R media. As I said at the start, I had no problems with this media when I first got the drive and didn’t end up with any coasters. Now the drive just grinds for 20 seconds and then asks for a disk to be inserted.
Thanks in advance.
