Looking in Activity Monitor under Disk tab, I can see what applications write to disk and how much MB. But, at the bottom the total shown is much greater than what all apps combined write. So I want to know which process writes all that extra ? I found that it is mds_stores, so I will google it.. I have to mention that: - I disabled Computer to sleep in Power saving preferences - I have installed Chameleon SSD optimiser and disabled hibernation/sleep image. - Also I got rid of the swap file, I don't remember how I disabled that
800MB in a period of less than one hour from the moment I started the system. I don't know how much it accumulates until the end of the day but I will check.. Is it just me that thinks its too much writing ?
Boot into Safe Mode and see if that process still causes lots of writes, if it doesn't then look to your login items for the potential cause.
Thanks a lot for suggestions, I have not booted into single mode, as that required to do some more research, but I disabled Spotlight and that solved the problem with mds. Meanwhile I managed to render Terminal not to start by changing some file permissions, as I wanted to look where written files are located, the biggest file written is snapshots.db now not needed anymore..
