    File Explorer hanging when waking a drive - normal?


    So, when I access an ext drive connected via USB, file explorer will randomly lock, is this normal? The PC is unresponsive for up to 3 or 4 seconds. It's not the only time it hangs but it is always when file explorer is trying to do something. save a file, open a file, etc. It's not regular or predictable. Anyway, that's a larger issue, but the ext. HDD thing, any advice? Thanks.

    Hi, have you checked what is shown in your task manager when this happens? (Have the task manager visible, then connect and try to access a USB disk).

    Look for any process using resources.

    You might consider disabling thumbnail generation and see if that helps.

    Does this change dependent on how full or empty the drive is, or the file types on the drive?

    Hello,

    I've always noticed a bit of delay while waiting on the hard drive to power (spin) back up when it had been turned off and accessed afterwards.

    You should repair NTFS file system errors and locate bad sectors and recovers readable information.

    Open the Command Prompt and execute Chkdsk X: /r command. Replace X: drive letter with drive letter assign to external HDD.

    It's really not possible to test it as it is utterly random. The task manager thing is hard as when it locks I can't access the task manager and when I do, the process that was running high is no longer running, like trying to chase my shadow. It just happened now as I was highlighting a dozen files for deletion, the system locked for 3-4 seconds. That was on an internal HDD. I've already done a reset and a complete reinstall from a factory image.

    A delay or locking of the system? This locks/freezes my system for 3-4 seconds.

    Basics:
    a. Check the physical disk e.g. HDTune (free version e.g. from softpedia.com) Health and Error scan tabs.
    b. If ok, follow @FreeBooter's post, but for the relevant disk.


    Task manager- have that open and visible prior to the event. However if processing is killed, it still might not update of course.

    - was this when you had no external disk connected?

    If the disk checks pass:
    Try running after doing a clean boot (Google if unsure how or see the relevant tutorial).

    Try running this:
    Enable and Disable Driver Verifier in Windows 10

    Are you overclocking? Have you made any changes to RAM recently?
    Freezes can even be due to PSU issues.
    Do you experience any in Safe Mode?

    I'd say it's more of a slight delay/freezing of whatever is trying to access the drive until it finishes spinning back up. Basically, it's just waiting on the drive to turn back on for access.

    Can you move the mouse pointer when it happens?

    Yeah, I remember them from Win7. The header would usually say (not responding) but these are different. The computer is locked and unusable, no mouse control and no keyboard control. There is no (not responding) just locked. There's a conflict somewhere but I just don't have the skill to even locate it let alone fix it. Could be a dodgy instal of Win10 from Dell, so even a factory reset just recreates the issue or I could have installed a program or app that is causing a conflict. I remember a very long time ago(15 years?) I fixed an issue that was a driver conflict, but I can't for the life of me remember how I found the error or fixed it.

    Could you type exactly what I should type if the drive letter is "D" please?
