ReadyDLNA database/index rescan

[xand]

Hi,

I currently have a ReadyNAS Duo using ReadyDLNA to stream media to my PS3. My ReadyNAS makes use of the power on/power off feature, so it powers itself down each night and back on each morning. I'm finding ReadyDLNA will force a full rescan of the MiniDLNA index every time the system starts up. A full rescan destroys the existing art cache and files.db, why is this the default behavior on startup?

I have around ~450gb of media being scanned, so the system being SPARC this takes a number of hours (about 6-7 at the moment). I have the 'automatically scan media files' option enabled, so inotify is being used to update the index/cache as any content in these directories changes, so at all times this index is going to be reflective of the file system. I think the full rescan behavior on startup should be changed, or at least given an option to disable this behavior.

Out of curiosity, how would these continual massive write operations affect the compact flash the operating system is running off? Would this not potentially reduce the longevity of the system?
