Im using windoze 8 and when I run restore point creator portable or installed I lose my 2 USB external drives.I have tried running SFC scan now but doesn't help.The only way I have been able to get my 2 external drives back is to use the system restore on the system. I would appreciate any thoughts or help that anyone has.Thanks in advance.BTW my updates are current but I have not installed windoze 8.1.
