Immediately after configuring my new system I noticed that when waking up I was missing 2 drives; those connected to SATA3_M2_M3, Yellow. The drives were available after cold or warm boot until the system entered sleep after which the drives fail to appear when the system wakes.

I didn't have anything connected to SATA2_2_3, Black. When I moved the drives from SATA3_M2_M3 to SATA2_2_3 they remain after wake-up.

Anyone know why that might be? I'm concerned about future expansion and having a real problem with those connections.

Thanks.
