Capturing on a hard drive with long stored files a bad idea?

[Master Tape]

I've been using a 2TB hard drive to capture my tapes for a while, and some files/folders have been stored on there for a few years now. Originally i just used this hard drive for additional storage for some stuff and for whatever reason never transferred the files off it. And capture with the remaining space.

Could doing this cause any artifacts with your captures? As for a while now i've been having this combing lines artifact (i'm guessing duplicated fields) appearing on my captures at random intervals, could happen a couple of times per tape, or once if im lucky.

No.

And why does the picture fill only about 496 lines of the 576 frame? Something is resizing an interlaced video improperly.

If disk is constantly being used it could be heavily fragmented.
Then during the capture process it could take too much time to write to it, assuming it is a spinning drive, not SSD.
That delay might affect your process.
Though, to be honest, it is a little bit of stretch.

Because it was recorded on analogue tv when it started broadcasting in 14:9 during it's latter years.

To troubleshoot further i wonder if it's anything to do with my settings in Virtualdub. Is capturing with a lossless codec like Huffyuv v2.1.1 on a Windows XP era PC fine, or will it be adding extra work for the CPU?

To troubleshoot further

Is that still image of an interlaced AVI playing in VLC? Try setting the deinterlacing to ON (Video>Deinterlacing>ON) or post a snippet here for the members to take a look at.

Yes it is from VLC and is set to deinterlacing.

Best to provide a video sample, a few seconds showing the problem.

Whatever codec you're using it is wrongly de-interlacing as Jagabo mentioned, Capture lossless and de-interlace and encode later, you think you're saving time processing on the fly but you are wasting more trying to figure out what just happened.
