Windows 10: Missing disks dev man shows 4HDD's Diskpart and Windows only show 1

Hi folks

I've 3 HDD's managed as a storage space and 1 HDD for Windows and a second partition D on it.

Bios at start shows 4 HDD's, Device manager shows 4 internal HDD's, DISKPART only shows 1 , File manager only shows 1 , computer management shows 1

















Whats up and how to I get access to the drives (booting up a Linux system on a USB shows that all 4 HDD's are working correctly).

Is it some hose up with storage spaces -- boot into insider build 17746 - all disks show up, boot into standard current Windows I don't see the HDD's. Even if storage spaces changed or something I ought to get at least undefined or Raw volume or something.

I know the HDD's are all good -- booting insider build 17746 shows all 4 with total read / write access and all files OK.

I'm sure some other people would assume HDD's faulty -- has Ms got a secret deal with Western Digital or something to get users to buy more HDD's. !!!!

Booting KYHI recovery diskpart gives HDD correctly although it can't actually handle the storage spaces directly but at least the HDD's exist and function !!!





Can't see why KYHI's disk sees them and Windows doesn't !!!! something wrong I think

Disk showing in Disk Management, But not DiskPart

Hello!

So, today I was doing a friend a favor, he had an old 1TB hard drive with important photos on it. He said he would appreciate it if I could move the photos to a different hard drive.

So, I hooked it up to my self-built PC (with a SATA port) and it didn't show up in file explorer.

So, I checked Disk Management to see if it would show up there, and it did. I later realized why it didn't show up in file explorer (Because it didn't have a drive letter). In Disk Management, I right clicked the primary partition only to find that it wouldn't
let me assign a drive letter.

I remembered there was another way to assign drive letters, with DiskPart. So I typed this into Command Prompt:

diskpart > list volume

In DiskPart, It showed the drive's EFI system partition (partition 1) but not the (Healthy) Primary Partition (partition 2).

Also in DiskPart, I could type "list disk" and it would show me the 1TB drive, if I then typed "list partition" it would show me the different partitions, but wouldn't let me assign a drive letter to them.

In summary, Disk Management showed the partition, but wouldn't assign a drive letter. DiskPart showed the partition 1, but not the primary partition.

My objective is to show the photos located on the 1TB drive's 2nd partition without erasing it.

I would be happy to add pictures if necessary.

Thanks!

 

Win 7 showing 746gb for 3tb drive?

Hi all.
Here is simple way to convert MBR to GPT in in Windows 7 only in 5 steps in Command Prompt !!!

• Open a command prompt (Go to Start, Programs, Accessories and then click Run as Administrator on Command Prompt ) and type diskpart.
  
  
• DISKPART> type list disk. (To see all your conected hard drives)
  
  
• DISKPART> type select disk. (Choice the number of the disk from the list that you will change like <in my case was "3">)
  
  
• DISKPART> type clean. (This will delete all partitions or volumes on the this disk).
  
  
• DISKPART> type convert gpt

THATS IT !!!
Now you have a whole hard disk space at one unallocated part in GPT partition and you can make any new type volume (one ore more)


P.P. - for windows ver:
Windows 95/98, 2000, NT 4 - No
Windows XP 64-bit can use GPT disks for data only.
Windows XP 32-bit will see only the Protective MBR. The EE partition will not be mounted or otherwise exposed to application software.
Windows Vista & Windows 7 (all versions) can use GPT partitioned disks for data. Booting is only supported for 64-bit editions on UEFI-based systems.
