USB drives 'drop out' Solved

    USB drives 'drop out'

    I'm running Win 10 Home, build 16299. I have 4 USB drives that I connect with a USB 3.0 hub w/lighted switches. I have a problem with the drives (I'll call it 'drop out'). After not being used for about an hour or more, I'm unable to rename, move or use any file due to the 'error code 0x8007045D".

    At first I was correcting the error by restarting the PC. This took over 4 minutes of the "restarting" screen before it did restart. I think that during this time it was correcting the error code because then the drive worked as it should. I now just throw the switch off for a second and then back on - problem gone.

    I don't know if the 'drop out' problem is caused by the USB Hub, the drives or the PC settings. This is a new laptop but I never had this problem with my old desktop PC.

    Would anyone have heard of this from anyone else?
    Anyone have any suggestion how to fix?

    Thanks for any help!!

    Build There has been an issue with this problem and KB4090913 was issued to fix it, but was then superseded by KB4090914. Do you have either of these updates installed?

    jamis - Thanks for your reply.

    KB4090913 was successfully installed on 3/6/18.
    I did a 'repair install' of Win 10 on or about the same date. Before this last repair install I have been a problem with KB4041994 not installing (8 times). I now have a listing of updates that show the same KB4041994 "Last failed install attempt on 3/128 - 0x80070643" (9 times now).

    Try grabbing and installing the KB4090914 update from the Microsoft Update Catalog manually. That often works, when automated attempts through Windows Update fail. OTOH, you could install WUMT from MajorGeeks and see if it will handle it for you (I usually try WUMT when WU doesn't work like it should myself).

    EdTittel - Thanks for the suggestion. I downloaded and tried WUMT but still failed.
    You said "Try grabbing and installing the KB4090914 update from the Microsoft Update Catalog manually". Not sure how to do that. Could you explain further.

    Thanks again.

    I put a link in my original post where you see the Catalog entry (here it is again for convenience: KB4090914).

    Here's what that looks like:

    Pick the one that's right for your PC (probably the top 1, the x64/64-bit item for 1709).
    Click the download link. It will download an executable installer file (with an .msi suffix, usually). Double-click the installer in Explorer, and it should install on its own. I figured there would be a tutorial on downloading and installing a Catalog update, but I can't find one. @Brink: if you think this would make a good (short) tutorial, I'd be happy to take a stab at it.

    Hey @EdTittel,

    Sure that would be fine. :)

    Aside from the KB issues.....what type of USB devices are you connecting to the USB hub? Are they portable HDD's, flash drives or something other? It could be related to a power issue; that of not getting enough power from the hub to the connected USB device.

    EdTittel - Thanks for pointing link to the Catalog entry. The link goes to KB4090914 (I need KB4041994). Also I tried the 3 links for Windows 10 and all stated that it would not work on my PC.

    Plankton - The devices are HDD. I can have 3 connected at a time or only 1 at a time and the same problem happens. When I have the problem I can open drives and folders and files. This shows me that the drives do not 'drop out', just not being able to rename or move files.

    Ha! Ha! Sorry, I flubbed the number. If you visit the base URL for the Microsoft Update Catalog (it's at Microsoft Update Catalog) you can search for any KBstring you like. Here's what I got for KB4041994:

    Are you sure that's correct? I was using the KB number (already quite familiar to me) from Jamis's post in thread #2. As far as I can tell your 4041994 update goes back to September 2017. It's no longer available in the update catalog, which usually means it's been superseded or obsoleted by some other, newer patch.

    Here's a reddit remark on this patch I find pretty scary, and which comes from an unimpeachable source!

    Same thing here on my Surface Pro 2 after I installed the fall creators update. I've tried everything on this microsoft windows update troubleshooting page (, except the performing of a clean install of Windows 10, but the issue still persists.
    Searching it up on Bing, I came across this forum ([it's Brink's announcement of the update release right here on TenForums] KB4041994 Update for Windows 10 version 1709) indicating that it's meant to be an update for insider builds, which I'm not using. I'm only using the rtm version of windows 10. Maybe that's why it keeps failing?

    Methinks that you should probably let this one slide.
