    SATA ports not working after windows 10 update

    Hello folks,

    I cloned my C drive and updated to windows 10 a week ago. Yesterday SATA ports 2 and 3 stopped working (on MOBO gigabyte GA-Z77M-D3H-MVP). I think it is a windows 10 problem because I have:
    • swapped my drives between SATA ports. All drives do not work in ports 2 and 3 and they all work in the other ports. So that eliminates the possibility of disk or cable problems.
    • checked that all ports are enabled in BIOS, and switched ports 2 and 3 off and on again to make sure.
    • swapped back to my old C drive, which is still on windows 7. All ports work fine with win7. I think that eliminates the possibility of a MOBO fault and since everything works with win7 I'm guessing it must be a win10 problem...

    It is strange because everything was fine for a week, problem started yesterday with no obvious cause. Anyone got any ideas?

    Thanks heaps...

    Sorry! I forgot I had installed more RAM and it didn't occur to me that might affect the SATA ports. Fiddled round and fixed the problem.

    The GA-Z77 MOBO has 4 RAM slots. I had 2 8GB sticks in slots 1 and 2 and yesterday I bought 2 more sticks, just because RAM is cheap. The new sticks have large heatsinks on them which I thought would interfere with airflow if I put them in slots 3 and 4. So I moved my old RAM to slots 3 and 4 and put the new RAM in slots 1 and 2.

    The SATA ports stopped working, but it didn't occur to me that it could be because of moving the RAM around. Just then I put my old RAM back into slots 1 and 2, and put the new RAM into slots 3 and 4. Bingo, all the SATA ports work. Then I moved it all back again, SATA ports still work.

    So I'm guessing my problem was related somehow. The RAM was showing up in my system, and after the install yesterday I did a windows memory diagnostic to make sure it worked. But today, removing the RAM and putting it back in fixed by SATA ports. Go figure!
