The first “bad” scan does show somewhat high PIF levels, but that’s an exception. The rest are generally decent, typically <1000 per disc. Some of them with minor buildup near the end. They all read fine, though.
but to be safe you might want to try burning them at 12x.
They weren’t written at 16, but at 4 or 6 mostly (maybe one at 8).
If I get a new drive at some point, it may very well be not a NEC. I’m not all that happy with it’s poor -R abilities (and I hear other models suffer from that too), and I read a few people reporting on newly purchased bad drives, which was also the case with my initial ND3520. (Among other minor annoyances).
MCC004/CMC/White printables are way the better media i’ve got from Verbatim
CMC from Verbatim? And by “white printables”, do you mean the MCC004 type I have now? In fact, I tried one pack of TDK/CMC MAG E01 which were more consistent than the MCCs. I may have considered switching to these, if it weren’t for some strange high PIF spikes that turned out better on a 2nd scan (see two attached scans).
Don’t put too much in those scans. Also NEC’s should scan @ 5x but i wouldn’t bother
Maybe it’s a problem with some drives, but mine seems rather consistent (with the exception of the above CMC, although besides the severity of the 2 spikes it looks very similar, especially PIF).
What do Prodisc and CMC have to do with Verbatim? I thought they are all MCC/MKMs. And which non-Verbatims use MCC?
I’d try returning them or contacting Verbatim (would they be interested? I wonder).
I may be able to replace them, but only if I return the whole pack, and that’s not gonna happen anymore. As for contacting Verbatim, I guess they wouldn’t give a damn, or just tell me to replace it locally.
You like trasfer rate checks, it seems (saw you mention it in other instances on the forums)
That was the only indication before I had drives that could scan (last one was a Yamaha CRW8824), but for more modern drives I consider it just a rough indication to what can be examined in detail thru C1/C2/PIE/PIF scans.
I do, on the other hand, verify checksums after writing, so I do get to see how fast they read. Some of these high-PIE ones slow down a bit near the end, but not all of them. And I think some are “slow seekers”, which I still don’t understand, but I’ve seen that with CDs too, so I guess the disc quality can somehow affect seeking speed.
Maybe I could get to test writing on this pack on a Pioneer DVR-108. Wonder how well that will work…
Anyway, I suppose from now on I’ll stick to buying 'em 10pcs at a time (this was my first lapse).
