Wow, that was one thorough review. (I didn't have time to post earlier- our company moved over the weekend and I was busy unpacking
). I particularly appreciate the detailed presentation of the tests you used and why you used them!
Thanks! I'm glad you found them to be interesting.
- one recording mode listed is Track Reservation. This is new to me. What does it mean?
Shoot! Dodecahedron asked me that one also in a private correspondence. I have to give you the same answer that I gave him: I don't know.
This is the first I ever heard of it also.
- the packet writing was really disappointing. I recall reading somewhere that CAV writing (which your comparison LiteOn drive uses) has advantages for this mode. This may explain part of the problems.
Potentially. CAV should make for faster random access time since the drive doesn't need to speed up and slow down as the pickup head moves across the disc. Would that make enough difference to explain my results? Certainly not for the Mt. Rainier tests, but it might contribute meaningfully for some of the other modes. Of course, I don't know for a fact that it is using P-CAV for packet writing. It does for session writing, but I don't have any way to determine what it uses during packet writing.
- for me, overburning is interesting if I have a complilation with 81 or 82 minutes and no 90 min blanks at hand. Otherwise there's no point. Does the overburning test in CD Speed work with this drive?
Yes it does. I should have included that tidbit in the overburning test results section.
- the advanced DAE error test with the specially prepared test disc was interesting. I'll try to make one of these too. I'm really curious how well your LTR-48246S did (I have its brother
That's right! You do. I had forgotten about that. You will be happy to know it did quite well:
The Lite-On went to about the 11-minute mark before the first C2 error showed up, 16 minutes before C2 errors started consistently showing, and 20 minutes before it slowed down. At that point it slowed down pretty considerably, but still kept going solidly. After it passed the damaged portion of the disc it slowly sped back up again but never did return to the pre-damaged section speeds. I guess the Lite-On lost trust in the disc.
Compare this to the COM4824 that started showing C2 errors consistently at the 9-minute mark. However, it didn't slow down as much as the Lite-On.
- did the C1 reporting in CD Speed work? The option doesn't appear to be greyed out, e.g. in this picture:
No, it didn't. You can check the box, but it fails at the start of the test with an "Error initializing test" message.
And I stumbled across one grammatic error:
after the first table in "Read Test - Audio CD-RW", it should say "reads audio CD-RW discs very slowly
I don't see any such error! Are you trying to slander me?!?
