Windows 10: Having issues with drive not mounting but showing on Disk Manager

Hi,

I have this issue where certain drives won't mount on to windows via my Sabrent USB 4 bay dock. It reads other drives but some it won't. I've tested it with varying drives and some mount and others don't.

This is when its working:



Below is how it appears when it's not working: This is the exact same drive.

W7 Hard drive partition issue

to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

- press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
- diskpart <-- start the windows command line partition management tool
- list disk <--- list the installed hdds in this computer for the next step
- select disk 0 <- might have to replace 0 with the number of the correct disk
- clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
- create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
- exit, exit to exit diskpart and the command prompt
- click refresh in partition manager and select your newly created partition and install to that

 

Disk Management

Hi Keith,

Thanks for providing the detail that was requested previously. Since the disk management screen that you saw is showing greyed out options, we suggest that you follow the steps below to change the partition type of your internal drive:

• Open Disk Management then right click the partition on the disk you want to covert and select Delete Volume.
• Once you complete the process you will see the whole disk shown as two separate unallocated spaces. Right-click the disk and select Convert to GPT disk.

After the conversion, you will be able to use the whole disk and then you can create new separate partitions.

We look forward to your response to our queries.

 

external hard drive showing up in device management but not disk management

Hi,

I recently tried to use a brand new Seagate 2TB External HD, but it is not showing up. It initially showed up, but after I tried reformatting it to exFAT32, it disappeared from the disk management list.

I then tried:

• refreshing the disk management list,
• inserting into a different USB port,
• re-starting my computer, and
• uninstalling the device from device manager/letting it refresh,

I still can't see it. There is no yellow error in the USB controller list.

I'm on Windows 10.

Intel i5-3317U @ 1.7GHz

Any suggestions? Thanks!
