PTT/bs - Gone back to basics - A working solution . .

Having read all your suggestions, listened to colleagues of mine using Prem and other NLEs, listened to wedding videographers and posting emails in many places, what comes out vey loud and clear is the "Wipe Clean" and "Start All Projects with Clean Drive" approach to projects.

I gave this a go this morning. I clear off everything from one of my 120gb drives - the I: drive, and d'yer know what? It works. The flow of DV is steady and the red indicaztor light now remains on, like it has never done before. I've dedicated one whole drive solely to the final rendered file - purely for PTTing. IT WORKS! - I may change my work flow and substitute my F: 60gb for this PTT drive and bring the other 2 x 120 gb up to F and G. I think I'll then squeeze in the 80gb to postion H: . Lots to play with here.

Yes, I know defragging should have the same effect. Done that been there - not for me. I can also hear others saying, " You should be able to do this even IF your hard disc is thrashing about searching for the bit 'n pieces of a DV-AVI file" - Well, maybe it should. I've throw in the towel on this search for "Nirvana" - I've got a scenario that at present works. The other thing is that I've been able to do is now "hot-plug" my Canon. So that's the theory of the drivers out of the window. The laptop is docked.

Honest, lads and lassies, I really do think this is it. It may not be PC-pc [politically correct!] in saying this, but having a dedicated PTT render drive for that final PTT file will be my choice for the coming few days - until it goes South again - here's hoping it don't.

Thanks everyone for your suggestions - and Grob, laptops may not have the processor speed we would like to think they have - yeah? Maybe there is something awry with our set-ups. Okay. Have a separate PTT drive will allow us to "live with it" - yeah?

Grazie

A part of me thinks that this looks like a case of a barely adequate drive (speed wise that is). All hard drives slow down as they fill up. That is because the data is beginning to be stored on the inner part of the disc. Think about it. Which has a bigger diameter, the outer track or the innner track? Bigger diameter means more data per rotation. More data per rotation means a higher transfer rate.

Average seeks times go up to if the drive isn't defragmented, but that's another problem.

To me it looks like your drive is fast enough on the outer zones but not on the inner zones.

Then again, another part of me finds it hard to believe that a modern drive is not capable of 3.5 MB/sec sustained transfer rate DV needs.

The only one way to find out is to try a benchmark:

Only the Disk Transfer Test needs to be run.

DD - D'yer what . . . I'm leaaving well al;one and get on with the reason I started this stuff - TO MAKE MOVIES!

That being said, I thank you for your technical prowess. For what it is worth all my drives spin at 7200rpm. I think you have a point - but pleased be happy for me - just this once - yeah?

Grazie

OK, no more tech stuff ;)

I'm sorry if you've said this before - I haven't seen it. What is you operating system?
