External hard drive and ExpressCache

RoRo, yes exactly my problem. My EHH is only 1 TB.

Also, notice now that ExpressCache is constantly accessing my primary hard drive with significant activity. Been doing so for a couple of days, even if I leave the computer on but inactive all night.

I am concerned that the longevity of the drives will be significantly reduced.

If I disable ExpressCache at start up, all problems go away, so I know it is ExpressCache.

To be honest, I do not see any real performance benefit with ExpressCache and because of the issues, will probably just leave it off until SanDisk does something to solve the problem 

Does anyone know if I can just reformat the drive wilth Windows to make it an accessable drive and just use it as a 2nd hard drive?
