As part of my regular recording routine I record on a EH-55 and later HS(in the silent mode) to Panasonic 3x RAM discs. Next I HS those discs to one of my other HDD Panasonics where I edit and compile the titles and finally when I have enough to fill a disc I HS copy to a -R. I'm forced to use RAM discs because they are the only discs that Panasonics allow HS copying between machines. Generally they work quite well but I do on a somewhat regular occasion have issues with failed burns.
I've tried all the workarounds mentioned in other threads at AVS including washing the disc with soap and water. While this seems
to help for a time, once I start having issues with a particular disc it continues to be a problem disc no matter what I do.
Everything in my workflow works fine until the final HS burn to -R(RWs act the same), it's here where one of the titles fails to copy over and the HS copy fails(resulting in losing the portion of disc space that the title took up). When I play that title back on my original EH-55's HDD it looks just fine but when I play back the RAM disc I see breakups which of course carry forward to my second Panasonic. The bad portion is generally only a few seconds to a minute long and if I edit it out(with shorten title) I'm able to copy it to -R no problem. I can also HS that title from my original EH-55 to another RAM disc and it also turns out fine. Thinking it could be the RAM disc I've also tried SHORTENING the title to only the bad part and not deleting it, figuring the bad portion of disc would not be reused, this does not work as I just start having problems on other parts of the disc.
I've also tried using different intermediate machines but failing happens at about the same rate. The failing discs are generally the most used ones but by most used
I mean maybe 30? times, no where near the 100k or whatever Panasonic claims for RAM discs
Besides washing the disc I've also tried reformatting them(I generally use ERASE ALL as some people think repeated reformatting can be hard for RAM discs) but once the disc starts having problems nothing really seems to help. I've also tried reformatting the RAM disc in my PCs(which can take upwards of 1hr) but this also does not help.
The only common denominator in my recording is my original EH-55 which doesn't really have that much use and I never have problems recording R or RW discs with it(at least that I've noticed). Due to my setup it would be extremely hard to swap out that EH-55 with another and because I only seem to have issues with RAM discs I just don't feel the problem lies there.
My most recent experiment has been to DIRECTLY record to RAM in my original EH-55(instead of first going to HDD and then HS burning to RAM) and since I have been doing this(for ~ a week) I have yet to have a failure
I've been using my "most prone to fail" RAM discs(the ones that would fail about every other time I used them when HS burning to it) so I think I may be onto something.
Does anyone have a idea of what might be going on? While I can continue to realtime burn to RAM I'm of the mindset of most around here that really NEVER like to use HDD DVDRs for realtime burns.
IMO RAM discs seem to be even more voodoo
than regular R/RW discs and truthfully I really wish Panasonic had allowed RW discs to be used(in VR mode) like the Pioneers but alas I'm stuck with using RAMs in my Panasonics. My Toshiba XS-35 apparently
supports RAM discs, I say apparently
because while the XS-35 works perfect in every other aspect, I've never been able to have it recognize a RAM disc...... Maybe like the EZ-x7 models(that I had horrific results with) I'm just not meant to use RAM discs
Mickinct, could you see why a RAM drive would act this way? able to burn to R/RW just fine and also RAM but only reliably in realtime?
