    Indeed because the partition has "unknown" (non-win) or no filesystem...
    I should have noticed that. I didn't. My apologies.

    If you can't find a Mac and don't fancy installing OSX in VMware
    A Live Linux CD or DVD should be able to read it, if there is actually a file system and it still contains files, Ubuntu for example and probably most other distros can read but not write OSX by default.
    Or
    Maybe try hfsexplorer, free which should enable you to read the partition if it is OSX Catacombae - HFSExplorer needs a java installing though.
    Or
    HFS+ for Windows by Paragon, has a 10 day trial before you need to buy it.
    Or
    you can use the drivers provided for Bootcamp https://forums.macrumors.com/threads...nload.1368010/

    EFI can stay, no need to remove from that drive. If it was set as GPT, you will see an EFI partition.

    You only need the drivers for Bootcamp, if you run Windows on a Mac. You do not need for a Beige Box. Only if the OP is mounting a Time Machine drive, which is in HFS(+) format, would you need the HFS software/drivers to read that drive. If it is a APFS formatted drive, which is now the standard with Mojave, there is no way without APFS from Paragon, MacDrive or UFS Explorer.

    I have a Seagate 2TB external Hard Drive ...... After many days of investigation and failed attempts with Data Recovery software..........
    Hi @UK Abroad,
    1. Just curious to know what all Data Recovery software you tried.

    2. I would suggest that you run a full scan ( No Quick Scan for Quick Scan will only find the existing partitions and not the buried old partitions) with Partition Recovery Wizard in MiniTools Partition Wizard free. At the end of the scan it will show a screen showing the found partitions ( existing as well as lost/deleted). I would think that it will also show the old partitions that could have been deleted. Just double click on each partition shown and check whether it lists your files.The one that shows/lists your files is the valid partition that could be recovered. But do not do anything in haste.

    Post a screenshot of
    a) How your 2GB Seagate external drive looks like in Partition Wizard ( the very first screen when you launch PW )

    b) the screen showing the found partitions after full scan

    c) the screen showing the list of files - if it shows on any selected partition


    After posting the screenshots just Cancel, cancel and quit PW.

    Note: You are only scanning the drive with Partition Recovery Wizard. It does not write or delete any data.

    Assuming PW is successful in finding the old partitions and could list the files, you need to install PW free version 9.1 to recover the partition/s. ( In later versions it is not free really
    )

    As I said I am working on the assumption that PW will show the accidentally gotten-deleted partitions.Let us see what we get.

    Shows how long it is since I stopped using Macs, wasn't aware they had changed the file system.
