I’m very grateful DrageMester suggested I run some tests on the PIF spikes produced by this 112D drive.
Just when I was ready to start using this drive for my backups, instead of my LiteOn or LG, I find that this drive is not all it’s cracked up to be. The PIF spikes are definitely affecting the readability of the discs, which may ultimately cause lost data or jerky playback. I can’t afford to scan every backup disc to see if there are spikes and even if I did, I’d be forced to do the entire backup again, if I found any.
It’s produced the spikes with all versions of Pioneer firmware I’ve tried and with several different media types. See the 112D/L scans thread for other examples. When I get time I’ll list some MIDs and burn speeds that they occurred at, in this thread.
The media affected appears to be DVD+R burned at 16x and 18x. Here’s the media and firmware that I’ve had out of spec PIF spikes with:
Verbatim MCC004 at 18x - 112D 1.21
Verbatim MCC004 at 18x - 112L 8.21
Verbatim MCC004 at 18x - 112L 1.22
Laser MCC004 at 18x - 112D 1.21
OEM SONYD21 at 18x - 112L 8.21
Laser MCC004 at 16x - 112L 1.22
BenQ DAXONAZ3 at 16x - 112D 1.21
OEM SONYD21 at 16x - 112D 1.22
Here’s one of the discs with PIF spikes, scanned in a LiteOn 5S drive:
