I just got a new retail SOHW-1693S. I've been visiting this site for awhile, and this is my first DVD burner, so I've been trying several different media, running Nero scans and Kprobe. This is the only DVD burner I have, so I've been burning and scanning using the same drive.
Anyway, the reason for my post is that I've noticed that I'm sometimes getting occasional "spikes", to about 100-110+, when I do scans, with both Nero CD/DVD Speed, and with Kprobe.
I've seen some posts indicating that individual spikes are not a problem, but I'm worried because, in my case, I think that these spikes sometimes seem to occur about the same area of the drive (about 1GB+, see the MCC004 and YUDEN scans), and I'm wondering if there might be a problem with this drive.
I'm posting some of my scans below. I've posted some of these in other forums (e.g., the DVD media forum), but thought that it'd make sense to put them all in one place for this topic (I guess I can only upload 5 images at a time, so I'll try post the remaining in a reply in a bit.).
All of these disks were created using Nero "Create Data Disc", except for the last set, CMC MAG M01, which was a copy of a DVD movie that I made with DVDShrink/Nero, and coincidentally, that scan that doesn't seem to exhibit the "spike" at about 1GB+, but does show a spike between 3GB & 3.5GB.
P.S. Sorry, I can't figure out how to intersperse text with the images below, but the scans are:
MCC004 - burned at 12x - scanned at 8x (NERO)
MCC004 - burned at 12x - scanned at 8x (KPROBE)
MCC004 - burned at 16x - scanned at 8x (NERO)
MCC004 - burned at 16x - scanned at 8x (KPROBE)
