Question windows dont reconize external hard drive

[payam.1994]

hi i have window 10 X64 and recently my both external hard drives are not showing in my computer.
my mother board is gigabyte h110m. usb ports work fine with mouse keyboard and even flash memory.
when i connect my external hard in my pc i can see the hard name in device manager but it dosent show in disk management .
i tried updating the driver of the external hard but its not work. and some times when i delete the driver it take to long(4-5 minute).
i have re installed my windows but nothing has changed .
also i tried to update my bios with Q-flash but in middle of updating system crashed.
next time i tried to update my bios with @bios app but again it show an error in middle of updating.
is that a hardware problem? or there is still a change to be a software problem?

the update BIOS crash is not good.
does the system boot now?

If so I would suggest booting into a linux distribution, completely change the software and test the hardware afresh.
Boot to a USB drive with linux on it. grab a USB drive, a copy of rufus and a linux distribution.
http://distrowatch.com/ has tons of differing linux distributions and download links. I personally am fond of linux mint with cinnamon.
https://rufus.ie/ the utility used to extract the ISO file to the USB drive.

use rufus to extract the selected ISO to the thumb drive. it will make the drive bootable and you can run linux from the drive once done.
Reboot into linux and proceed to test the hardware. connect to internet, watch videos, await problems.
if linux is good and stable the issue is most likely inside windows or otherwise software related.
this is a test of the hardware.

boot into the live linux distro of your choice and when it loads see if it can see the drives and that they are working as usual. if linux shows well behaved working drives, the issue MUST be in Windows, a program or a driver or other software issue.
if linux reports the same issues as Windows, hardware somewhere in the chain is down, USB, the cables, the bridges in the externals or the drives themselves.

tnx for your asssist and reply . yes system works well after trying to update biosand i was about to test linux os but i figure out my front usb ports can reconize my external hards but back ports still cant

back usb ports dont work in linux os too

"when i connect my external hard in my pc i can see the hard name in device manager but it dosent show in disk management" This is opposite of the issue sometimes seen with external drives. When you check Disk Management, make sure you scroll down in the window that shows the installed disks. An external drive will be last and at the very bottom of the list, so you won't see it until you scroll down to the bottom.

as i said i can see my external hard in my computer and in disk management when i use front usb ports but when i use back usb ports i just can see my hard name in device manager(not in disk management and my copmuter)

First I would make sure you have the most recent chipset driver. https://www.gigabyte.com/Motherboard/GA-H110M-A-rev-10/support#support-dl-driver-chipset If loading the driver doesn't work, or if you already have the most recent chipset driver, boot into safe mode, go to device manager, and delete all the usb devices and drivers, than restart and hopefully reinstalling the chipset driver will help.

my bios version succsesfully updated to version 23(2017) from verison 20(2016)
chipset driver wasnt the latest update so i downloaded latest driver and update it and did what you said about deleting drivers in safe mode but still nothing

So, confirm, with the external drives plugged in, you have deleted the entries in Device Manager, under Disk drives? And then clicked on, "scan for for hardware changes"?

From this link https://ccm.net/forum/affich-522124-external-usb-hard-drive-don-t-show-up

• I went to the Device Manager (you can just search it on your computer and you should find it)
• From there, I went to/expanded Universal Serial Bus controllers.
• There's a whole list there of all different devices and stuff, but one of them there was titled "unrecognized device", or something like that. I opened that and went to the Drivers tab, and there, I uninstalled the driver. It gave me a warning before that I was deleting the device from my computer, so if you get that, don't worry, just do it.

(*After I uninstalled the driver, I then clicked the button to update drivers... but it said the computer already had the latest driver installed. That kind of confused me because I thought I just uninstalled it, but either way, maybe for you it doesn't update drivers automatically and you'll have to do it there. You need the latest driver for it to work. I guess for me that step was unnecessary.)
* My external hard drive now showed up on Disk Management!

here is a screen shot of my device manager . there is no unrecognized device in universal serial bus controllers

Well, at this point I'm at a lost. Hopefully someone else will chime in.

im just sying it if some one else in future got this problem. i didnt find any software solution for this problem .
