    External HD - Partition Unallocated


    Dear All,

    I believed that I have accidentally unallocated the partition of my 1TB external hard drive.

    Not sure if this was the cause, but a day ago, I intended to migrate my existing data in 1TB external hard disk to another 4TB external hard disk. Then, I came across the Computer Management by chance, and had decided to appropriate my 4TB hard disk into 2 partitions. However, I have accidentally named the newly created partition's drive letter to the same drive letter as my 1TB hard drive. After which, I could not access to my data in 1TB hard disk, and my disk becomes Unallocated as shown below.



    In attempting to recover my data, I have read a couple of web articles and forum threads with regards to this issue, and it seems that the only recommended course of actions for me is to use Partition Wizard - Partition Recovery Wizard. I have chosen the 'Quick' Method.


    Is this correctly done? Do I have to do anything else?

    Please do kindly advise.

    Much appreciated. Thank you so much for reading my thread.

    Best Regards,

    Hi and welcome to Seven Forums. Your system spec says Windows 8.1 64 bit. You could have posted your query in Eight Forums. Never mind. We shall deal with it here.

    First and foremost without seeing the screenshot showing how your 1TB external drive looks like in MiniTools Partition Wizard we cannot give any further instructions. I also see that Brink has removed the broken images in your post.

    So you must first learn how to take the screenshots and upload it to Seven Forums.

    Give these two tutorials a good reading. 1. https://www.vistax64.com/tutorials/1...ool-vista.html 2. Screenshots and Files - Upload and Post in Seven Forums

    Next if you had downloaded Minitools Partition Wizard version 10/10.1/10.2.1 and above , uninstall it and install version 9.1 which you can download from here http://www.filehorse.com/download-pa.../old-versions/

    Safely remove all external drives/Flash drives and plug in only your faulty 1TB external drive.

    Run Partition Wizard 9.1 ( Say NO to new version) and post a screenshot - the very first screen after you launch PW showing your drives. It should look like the one below basically - of course your external drive may show differently and that is what I want to see.

    After you have inserted the image/s in your post, click on "Preview Post" and check everything is fine. Then click on " Submit Reply" ( I invariably preview all my posts before I submit.)

    Thanks for the response.

    I have installed the V10. I will uninstall V10 and get V9 later on. Anyway, in the attachments, you can find the screenshots to my issue.

    You seem to have deleted the single volume on your 1TB drive and initialised it as a GPT drive. I have to workout a solution for this which may take sometime. So please wait . (Do not do anything other than what is asked for now.)

    In the meantime. please do this and post a screenshot.

    Partition Wizard 9.1. Only your 1TB external drive plugged in. Run PW. On the left pane click on Partition Recovery Wizard > Next > select your 1TB drive > Next > Full Disk > Next > Full Scan > Next. Allow full scan to complete which may take quite sometime. On completion take a screenshot of " Choose Searched Partitions Window" showing all the found partitions. After taking the screenshot, click on "Cancel" on the right hand side bottom Corner and then close PW. ( Do not click on "Finish")

    Post the screenshot. I shall return after doing some experiments. So be patient and do not try anything on the 1TB drive.

    Going forward, in the future, give each of your hard-drives unique names; give each of your created by man partitions unique names. That way, you always know what any particular utility is "aiming" at. Jumanji wants the other good HD disconnected so it is not accidentally "aimed at" and acted upon.

    Thank you so much for the help! This is the current screen. I will post it again once it is done with scanning.

    Anyway, just a FYI, not sure if this was partly the cause. My Disk 2, which is the HD-in-question, was previously encrypted when the unallocated results. Now it seems like I couldn't decrypt it as well. :X

    Thanks for the help again! :)

    Yeah. I have painfully learned my lessons now.

    I shouldn't have played with "Disk Management".

    Hi Aomatsu, I had completed my experiments.

    Please post a screenshot when Full Scan is completed just for record. ( I repeat again do not click on Finish but only Cancel)

    I said just for Record for it is no longer required. Since you had started it let it complete)

    Now the solution to bring your 1TB drive back to it earlier MBR state.

    I have confirmed that this works.

    (If you get any other screen showing any other partitions apart from the one starting at LBA 2048 then take a screenshot and again Cancel Partition Recovery Wizard and close PW. Post the screenshot and wait for further instructions. I only hope that this does not happen.)

    If your drive is restored to the original state do not get alarmed if it does not show up in My computer/ Windows Explorer. You may need to give it a drive letter which you may do in Windows Disk Management or even Partition Wizard. In Partition Wizard right click on the partition, click on Change Drive letter, select a drive letter and click on OK. After that, click on Apply in the top menu bar.. Now you may be able to see and access the drive.

    After everything becomes normal try to decrypt. ( I do not know how your encrypt/decrypt works and I may not be able to resolve any problem with it. If there is a problem you have to seek other experts' help. )

    The first full run is done. Here ya go:

    I have also changed my External HD by 'Covert to MBR' in my Disk Management.

    Restarted my PW, it now shows 'Logical' instead of 'GPT'; running full disk and quick scan now. Here's the screenshot:

    Will update you again once the scan is fully completed.

    Thanks a lot mate!
