remove hidden attribute from disk partition RRS feed

  • Question

  • 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.
