    Hi, I have a HP I5 8 g Ram on Win 10 64bit. I have numerous USB Hard drives that when I plug in, some show in Device manager but not in Disk Management. Others do not show at all. These are a mix of Toshiba and Seagate 1, 2 & 3 Tb Drives.When I go into Properties all have a lot of info in the events box.
    All 5 of these disks work fine on my laptop it is just the Desktop that I have the problem.

    I also have a lot of errors showing up in Event Viewer but not sure how to tackle this problem, Please Help.

    If you have errors in vent viewer= Left click on the error,and it will bring up a little box showing error, and error code.
    If you click to go to Microsoft to check it, it will on many occasions give you an answer (not all, unfortunately)
    Otherwise copy the error codes, and post them on here, and we should be able to look into it for you.
    I would suggest this as your first step.
    Now, another thing that I have often come across is that different hard drive settings can mean it fails to read them properly- MBR-GPT differences, W7/8/10 DIFFERENCES ETC:
    After trying to solve the EVENTS, I would download, and install Partition Wizard, and then check these hard drives using Partition Wizard

    Hi baklogic, and thanks for the reply. These drives are completely readable/usable on a win 7 laptop, another Win10 desktop and a Macbook it is my 1 main desktop on win 10 that will not recognise them. I dont think I need to use the Partition Wizard???
    The warning codes mainly state
    "Device USB\VID_0480&PID_B207\20161221021048F was not migrated due to partial or ambiguous match."

    This is one of many,

    Device USB\VID_0480&PID_A200\20140826003336C was not migrated due to partial or ambiguous match.

    Sorry I had not come back before-I have been off colour, but getting back to normal, now.
    I had a similar issue with W10 and W7 hard drives not recognising a hard drive, when one hard drive had an MBR, and the other had GPT formatted hard drive.
    I would follow plodr's method, but I would look up each individual event, and try to solve one at a time- one fault may well solve others once sorted.
    That was why I suggested Partition Wizard, as it can tell you-what each disk is in which mode-MBR/G[T, without doing anything else.
