I have been using an NEC 3550 as my drive for burning. I will also occasionally run error scans on random discs using the same NEC 3550 with CD/DVD Speed. Usually they come out acceptable and I just move on.
However, recently I burned about 20 DVD's on Verbatim DLP Inkjet Printable +R, MCC003 (Made in Taiwan) disc . The first few I tested came out ok, and then I started to notice large spikes on some of the discs. Being concerned about bad media, I decided to scan them on a different drive on another PC. I used a BenQ DW1650 to scan the discs that the NEC reported bad. The BenQ drive reported the discs completely different, with no large spikes.
To change it up again, I decided to try testing a different media on both drives. This time I used a Maxell -R, MXL RG01 (Made in Japan) disc burned in 2004 on an NEC 2500A. The results on this were much worse on the NEC end. The NEC drive reported huge errors thoughout the disc and running the ScanDisc utility showed about 99% as damaged on the surface scan. The BenQ drive reported the disk completely different and showed no errors on the surface scan.
is a link to the scans that I made from both drives.
I'm basically looking for advice on whether I should continue to use the NEC 3550 for burning and just get a different drive to scan with. If it looks like the drive NEC is degrading, I could switch to a different drive for recording.
I have a Pioneer DVR-109 available or I could purchase another recommended drive. Getting the BenQ DW1650 that I scanned with is a possible option as well, but it is in another family members PC and I would have to replace it with a reliable substitute.
Any information or advice would be greatly appreciated.
