Thanks alot for your advice. But I don't understand your writings.
If I don't make video editing for one or two mounths but I use my PC
for internet surfing only, why would have to mont the drivers inside
the PC? I think the heat will damage them (a little bit) and however
even if I will not use them for two mounths, they will works a little
bit.

According to the _IMHO reliable - Google hard disk test (from Neowin):

'The impact of heavy use and high temperatures on hard disk drive failure
mdisk_faiay be exaggerated: "Our data indicate a much weaker correlation
between utilisation levels and failures than previous work has suggested. We
expected to notice a very strong and consistent correlation between high
utilisation and higher failure rates. However our results appear to paint a
more complex picture. First, only very young and very old age groups appear
to show the expected behaviour," the authors noted.

There is a widely held belief that heavily used hard disks are more likely
to fail than those used intermittently. It has also been thought that hard
drives preferred cool temperatures to hotter environments. The engineers
found, however, that hard drives less than three years old and used a lot
are less likely to fail than similarly aged hard drives that are used
infrequently. The authors of the report speculated that drives which failed
early on in their lifetime had been removed from the overall sample leaving
only the older, more robust units. The report also noted that there was a
clear trend showing "that lower temperatures are associated with higher
failure rates. Only at very high temperatures is there a slight reversal of
this trend." But hard drives which are at least three years old were more
likely to suffer a failure when used in warmer environments.'

I saw that report a while ago and found it very interesting. It turned my own theory on hard drive failure on its head!
