  1. Repar HDD partition table in Windows 10


    I have two 4TB HDD's that were in a Qnap NAS. The partition table on both has apparently been corrupted. The drives will not show up in the NAS. I took them out and installed on a computer with a USB adapter. They show up in Disk Manager with all partitions, including the main data partition, as RAW. I tried to analyze with TestDisk, but it did not show the correct disk size (1.8TB vs. 4TB). The same reduced size shows in the computer's UEFI, but the full size shows in Disk Manager. I am leary of EaseUS or Parted Magic after reading some poor reviews. Is there a way to repair the partition table without deleting the data; and if not, what is the best recovery tool to copy the data off of the drive?

    :)

    How to delete the GUID Partition Table (GPT) on a HDD

    Greg,

    Thanks for the reply... and, your Windows Clean Install Guide is great. I'm actually using it for this build I'm working on.

    Yes, I plan to use GPT - but, I want to delete sector 0 on the HDD to get rid of the old MBR partition table and I also want to delete sector 1 on the HDD where the GUID partition table (GPT) is located. I am concerned that the virus may have infected the
    partition tables.

    I would think that deleting the HDD partitions might clean out the HDD partition table - but, I'm not positive. So, I want to delete both the MBR and the GUID partition tables and I do not know of a Windows DISKPART command that can do that.

    I am so paranoid about this virus that I am even re-flashing the UEFI firmware back to factory settings using a switch located on the system-board.

    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
