Disable System Restore on the data volume. In
Control Panels : System : System Restore you have per-partition
control. There is no point in having System Restore on a videos disc.
Each time a new disk is plugged in, it gets enabled in there. The
only thing that should really be enabled in there, is C:. Doing it
for other partitions is a waste (more disk activity for nothing).
You could change the volume from using 4K to 64K storage. If
you are only storing large files, that might work better.
Note that certain features become disabled when you move away
from the default 4K choice for NTFS (compression, ability to
If more than one writer-process is at work on the disk, then
it is going to get fragmented. So two tuners dumping to one disk,
is going to fill the disk with red.
Even the MFT can become fragmented. I do not know if there
is a way to make it bigger before using the storage on
there or not.
The drive will probably still be "filled with red", but
you can try to make things better.
Comparing defrag to copying the entire disk, it depends
on what the performance monitor shows for read/write rate
while you defrag. When my computer is fixing fragmentation,
I generally see about 3MB/sec transfer rate. How long
would it take to process a 2,000,000 MB disk ? If the whole
disk is fragmented, copying it might be faster. I am not sure
I see a point though. I do not defragment data volumes.
Takes too long.
For video playback, if a disk were heavily fragmented, it might only
manage around 1-3MB/sec playback rate, which might not match
the requirements for some HD video format. Maybe the 64K
size change, would be enough to improve that. You can time the
time it takes to copy one (fragmented) video file, from one disk
to another empty disk, and use that copy time as an estimate of
the average read rate achievable during playback. If the video
format happened to need 8MB/sec playback rate, you could compare
the result to that number. If the copy happened much faster than
that, you might not need to change anything.
Having multiple tuners dumping to the same disk, is as likely
to be a source of trouble, as any other. Having a real-time
defragmenter, might fix it, but again, I do not know what
impact that is going to have on the disk. Just more thrashing.
During movie playback, an AV program could be scanning the
video stream, at the same time as you are viewing it. That's
probably not a big deal. An little more processor perhaps.
