There is no guarantee that switching from RAID to AHCI and then to AHCI again will not affect the caching or the RAID configuration, so it is best to back up your data before you try this, I would not worry about cached data though, since this is constantly being re-written.
Hi, thanks for the reply. So, switching to AHCI does not delete the cached data or make it unreadable after going back to RAID? The only reason I ask is that if I do unaccelarating the drives first in RST, I'm too lazy to wait for all my most used programs to eventually work their way back into the cache. So, just to clear it up, if there is any chance at all that switching to AHCI before unaccelarating the HDD will make windows unbootable after turning RAID back on, I'll unlink them first in RST. When you say that it could potentially affect the caching, but you then say not to worry about the cached data, what do you mean?
Also, would switching to enhanced mode, (So that the cache date is written to the HD) then switching back to maximized mode be an effecting method of backup?
