Hello,

im just planning to set up a new system and have found out about fancycache recently and plan to use it in the future.
one information i couldnt find in here or the help is this:

if im using a deferred writing cache with a loooong interval (hours), will this allow the disks, where the data will be written to, to spin down?
as far as i understand FC windows will not notice that there is no real access(coz goes to the cache first) to the physical hard disk .. so does this imply that windows will not spindown the disks because it thinks they are used actively?

regards,
mikk

Windows will spindown the disks.

Please note when Defer-Write is enabled, a power outage or system failure might result in data loss or corruption.

To my experience, even on a system with low activity the harddisk does never spin down (tested with Windows XP and Windows 7). I have spend seral days in investigating this. At the end I gave up and accepted that the hd does not stop.

thanks for the reply support!
yes im aware of the implications and would use it only on a certain computer (and disk) where it makes sense and doesnt risk unique data

@frank.. LOW activity surely will lead to this (depending on your windows settings, the default is 20mins of NO activity before win7 is spinning down). FC should (and does so, as it seems) prevent any (writing) activity on a disk with the correct settings.
but you are correct .. at least on your OS partition its almost impossible to make windows go idle with reading/writing (tho FC can help here a big time too) as its almost nonstop doing something (logs, precache, indexing .. and not everything can be stopped)

Hi Mikk,

in my case: even with an idle time of one minute the hd never stops. What I do not understand is that the W7 resource manager does not indicate a process which access the disk. And yes: its the OS disk, but no indexing, no precache, plenty of services disabled, logs of course but FC is active with R/W and defer-write. I did the same on Windows XP: same result: OS hd never stopped.
