No, really, AV drives don't exist now Granddad
I honestly don't know why people insist on posting comments about this, it's a non-issue.
In the old days (pre-2000), hard drives had a thermal recalibration phase and now they don't. No, they haven't rewritten the laws of physics, they just make them differently that's all. If you had been arsed to Google for an answer you would have found this as the 2nd hit:

Nowadays, if manufacturers promote a drive as ideal for AV, it just means that it's quiet and doesn't get very hot, that's all.
Secondly, I am not complaining, not to you or Sky. Of course it's my lookout if I replace my hard drive, I know that because there's a big fuck-off "Warranty Void" sticker that I had to break to open the box.
Finally, in case there's anyone left on this comment page who still has the will to live after wading through all the uninformed shite, I can happily report that putting my original 40G drive back in my Pace V2 box makes it work very nicely thanks.
Incidentally, neither the original 40G drive nor the big new drive I replaced it with were special magic AV drives. They are just ordinary vanilla bog-standard Seagate drives, so can we please give it a rest with the AV drives now?
