From uTorrent's (which I, myself am using and was bought over in
2006 by the company who made your BitTorrent 6.0 client) FAQ:
This means that the disk was not able to keep up with the
read/write speed. To fix this, you can change the options
in Disk
Cache.
However, if this happens when adding a torrent, it is
normal, and due to a design limitation in µTorrent, which will be
fixed in the future, not because your disk is actually overloaded.
It will disappear after a few minutes.
(1.6 and later) While the defaults should work fine, even up to
100Mbit, you may want to alter the disk cache options. You will
find the options in Advanced -> Disk Cache. To see the current
cache use, look at the Speed tab, and choose Disk Statistics from
the drop-down list.
So, are you running something disk-intensive while torrenting?
If not, it may be due to the fact that your HDD is slow/dying, or
incorrect configuration of the memory cache settings. You may want
to try the settings shown in the screenshot below.
