"Uninvolved" disk appears to be busy during DVD wr

[Greggy]

I have all of my video stored a 300GB USB2 drive (the Z: drive). I am creating an ISO file on that drive, which I then use to burn multiple DVD's on my IDE burner (The F: drive).

Whenever I do this, my C: drive (OS and VS 9 installation partition, FAT32) is constantly busy for as long the DVD is burning.

Since both the Z: and F: drives are DMA enabled (and even if they weren't) there would seem to be no reason for the C: drive to get involved, other than loading the burning engine once at the beginning.

Anybody know why it's so busy when it should be butting out?

Could this drive being FAT32 be why my DVDs are getting truncated, even though the source MPEG and resulting ISO files are on the NTFS formatted drive?

Thanks,
Greg

Greggy,

It sound to me like your C drive is being used by the disc burning process as a temporary buffer. Sounds perfectly legit to me since your operating system and assuming your pagefile is as well are on the C drive.

BTW, what program are you using to do the burning?

Unless you change this, the default location for temporary files created through Windows APIs would be your boot drive -- that's why the internal drive is busy.

If your using Nero to burn the iso there is an option in the
burning screen "On the Fly" (may or may not be there).
To eliminate the buffering either click that on or check the boxes OFF
that reference "Cache network Files" & "Cache files smaller than 64K".
Any reference to caching, that may help.

Well, scratch that theory.

All the involved drives are NTFS, so the 4G file limit should not be affecting my burns.

At the end of these "bad" videos, there's an artifact on the screen (Half a screen of blue dots) then it goes back to the menu briefly, then it starts playing over again, although the counter on DVD player continues on from 62:34 minutes. It's always at 62:34. Very odd....

I'm burning using VCD DVD Disc Recorder, the minimalist utility for burning ISO's that is included with VS9. Check start->programs->ulead video studio 9.0 to find it.
