Windows 10: My Portable Hard drive's partitions are undetected by diskmgmt & diskpart, but Minitool does..

Hello,I have Windows 10 Pro 21H2 installed PC which happens to show only the first partition of my portable hard drive. I don't exactly know whether this happened after installing the latest update or not. But I can confirm. I didn't have such problem before.I tried it on another Windows 10 Pro PC probably had 21H1 or previous version Windows which showed all the partitions as it should.What could be happening here. I can backup data using another PC and repartition using this PC to see what happens. But just seeing whether there is a way I can do that without taking the trouble.Thanks in ad

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

 

Question: MiniTool Portable Partition Magic ???

Howdy, Bree:


I successfully implemented your instructions.


Default PowerSpect 1510





I have (1) issue to resolve (see printscreen):

• Not able to CREATE more than (4) partitions on Disk 2.

Might you suggest a SOLUTION?


Thank you much in advance.

Partitioning My Hard Drive Without Losing Data


Download any of the suggested programs above and fire up Youtube for a step by step instruction. Easus is a good software. But I personally use MiniTool Partition Wizard.

It will only take 5 minutes to become a professional hard drive partitioner.
