    Part-format recovery with MBR repair ?


    OK, let the public ridicule commence... like a complete muppet I started a format HDD on the wrong drive!! (It was meant to be my usb stick, not my second HDD!)
    The info on that drive is priceless. All kids photos, wedding photos, you get the idea and I've now got myself a new HDD to use so they can be backed up to another physical location.

    I see there are recovery tools for this, some are £60/£80. Ok fair enough, that'll teach me, but I understand the files will come back without their original file names and so probably not in the same directory structure.

    Then I came across the term MBR and a repair tool specifically for that, which is related to drive structure/initialisation (??)

    My question is, if I use an MBR repair tool, will that map the way for my system to re-read the original files / names / structure?
    Or even if not, Id be happy to have 100's of files in a root directory (because it will save me £60/£80 on an alternative recovery tool?

    btw Im only presuming its MBR. Upon initialising my new drive I was prompted for MBR or GPT but when Ive had new HDDs in the past, I dont recall being prompted for that selection.

    Thanks :)

    The MBR only defines the boundaries of the partitions. It has nothing to do with any content within that partition. If you just straight up deleted the partition itself, and wrote nothing to that area on the disk, there would be a good chance that MBR recovery could easily and quickly bring back the deleted partition with everything in tact.

    But, you did not do that. In formatting the partition, you did nothing to the boundaries of the partition itself contained in the MBR. You altered the contents of what was inside the partition. A quick format wipes out the table that keeps track of which sectors contain which bits of which files. The data for the files are actually still on the disk, but the map that tells the OS and disk controller which data belongs to which file is gone. The file recovery software can examine the data left over on the disk and analyze it and try to piece it back together into files.

    A full format, on the other hand, actually goes through an erases the data itself in the partition, not just the table that defines the locations for data belonging to files. That requires extremely sophisticated analysis of the physical platters inside the drive to recover data.

    Thanks Navy,

    Although not the answer I was looking for, that makes sense.

    I did forget to mention that although it started out as a full format, my realisation happened very quickly in to the process... a few seconds, 30 at max before I cancelled the process, so although it started as a full format writing zeroes everywhere, I would hope that most of the data is still actually there being a 2Tb drive.

    Understand your concern...

    Since you didn't touch anything since. You have great chance of recovering your data, I'm not really aware of today's popular partition recovery means, but I always had great results recovering deleted partition with Paragon HDM.

    Depending on your computer confidence versus the value of your data, only you can decide if...

    1- Your going to try to manually fix the issue.

    2-Use specialized software to do so.

    3-Use Advanced technical support to help you use specialized software.

    4-Use Professional recovery services.

    Most of the time it ends at option 2. Use specialized software that will help you understand what you are doing. (That's why they cost something.)

    If you are really unsure of what you have to do and greatly value what's in jeopardy... Consult a specialist.

    Hi @DarkTitan,

    At the outset let me tell you that I do not have a ready solution for your problem except that I have a rough plan to try.

    1. Initialise your flash drive ( Just initialise and stop. . Do not Do not Do not proceed any further) Initialisation will just write the MBR to sector 0 and make your flash drive recognisable instead of saying "Unknown - Not initialised"

    2. Post a screenshot to see how your drives look like in Windows Disk Management.

    3. If you have MiniTool Partition Wizard installed, post a screenshot how your drives look like in it.

    4. Once I see it, I may recommend you to run TestDisk, use "'Advanced - File System Utils" in it to find out tha status of Volume Boot sectors and rewrite the Volume Boot Sector.that could have been lost if its backup is present. ( This part I shall guide you to run TestDisk, if I think that this plan may work.)

    Apart from the above two screenshots, you need to furnish complete details of your flash drive, its capacity, and its file format that existed - whether it was NTFS or FAT32 or ExFat. I may need to simulate your drive conditions and check whether the above plan is feasible. Without knowing the file system that existed, it is not possible to carryout the experiment.
