This is on BD IS 2008.
For several months now I am hearing the drive keeps accessing something every 1 sec ... it bugs the heck out of me.
I found out it is Bitdefender. According to the file monitor (from SysInternals) BD keeps trying to read or write the livesrv.log, antispam.ini, and fwrules.dat files in a continuous loop.
If I put my ear next to the hard disk I can hear it working constantly, tak, tak, tak, tak, tak ... (every second) and it corresponds perfectly with the "write" action for the above mentioned files.
Is this a bug ? ... or by design ?
