Much earlier this year I put on -RAM disks the entire first seven years of Supernatural, from TNT. I have been slowly editing and writing them to -R disks. I have over 100 episodes finished, and so far, only two have had the "evil bits" problem, where the parity check seems to fail. I have been really happy about that. Sometime last year I did the same with the Dick VanDyke Show, and again, only had one or two bad burns out of 150 or so episodes.
I have seen what you talking about, the -RAM disks acting dodgy, but that has not been the case lately, at least for me, at least until this incident yesterday.
I am hoping that we can figure out what is the culprit behind these problems.
T-Y -Rs had been working great until the JVC debacle. That was when I started to get burn failures. It was funny, but in a particular batch, several disks would fail at almost exactly the same point, say when the burn was 62% done, or 48% done. Then in the next batch, it was somewhere else, but still, very consistent. I changed all of my Panasonic DVD recorders so they never progressed from 8x to 4x,* and the problems disappeared. I still do a "disk verification test" on every disk I burn (It is a function provided by my DVD duplicator) and since I switched to 4x, the duplicator hasn't caught a single bad burn.
* From page 58 of the Panasonic EH59 manual:
DVD Speed for High Speed Copy
Select the speed of high-speed copying (When using high-speed copy compatible DVD-RAM 5X, DVD-R, +R 8X or +RW 4X discs).
[Normal ( Silent )]
The noise generated by this unit when "Silent" is selected is less than when “Maximum” is selected, however the time required for copying will
In Panasonic's jargon, I expect maxamum is 8x, and silent is 4x.
I expect mickinct is getting a lot of business now as these machines hit their sixth, seventh and eigth birthdays.
I just wonder, and worry, about how long his supply of laser emitters will last. By then, hopefully, we will have moved to infinitely deep holographic crystalline storage with V/R direct neuro stimulation, and NO glasses required!
