remove hidden attribute from disk partition

Question

_{Saturday, April 6, 2019 3:14 PM}

I have a 2TB seagate NAS drive setup up as 1TB mirrored.  One of the drives went out but the second one seems ok.  Hoping i could recover at least some of the data, I purchased a SATA / USB adapter (suggestion from Seagate support).  I am able to see the Disk in "Computer Management / Storage / Disk Management" but when i right-click on the partition, all options except "Delete Volume" are grayed out.

Using DiskPart I select the Disk and Partition but when i enter Detail Partition, I get the message "There is no volume associated with this partition and the Hidden attribute is "Yes"

==============================

DISKPART> detail disk

seems to be a Linux RAID partition: this can not be read by Windows.
boot from a Linux boot drive to access it.

diskpart
list disk
select disk N  where N is the number of the disk to be selected
list partition
select partition N where N is the partition number to be selected
detail partition
you can do a list volume and then a select volume to be sure
list volume 
detail volume 

To clear the Hiddden attribute:

ATTRIBUTES VOLUME CLEAR HIDDEN

To set the Attribute to Hidden:

ATTRIBUTES VOLUME SET HIDDEN

To view the contents of a hidden partition you have to assign it a drive letter with

ASSIGN LETTER=X     where X is the drive letter to assign to the disk

On a HIDDEN Volume there is NO drive letter assigned.

Once you have UNHIDDEN a volume, use the ASSIGN command to assign a drive letter. the disk will then show up in both disk management and windows file explorer.
