Yes. EFI System partition - Wikipedia, the free encyclopedia

The PW Surface test is available on the right click context menu and an able scan of the HD condition. However since the partition type may need to be adjusted I would wait for jumanji, Ahmad or SIW2 who are skilled in these most advanced operations to advise before doing anything further.

Thanks Greg, I found this interesting too.

Both GPT and MBR-partitioned disks can contain an EFI System partition, as UEFI firmwares are required to support both partitioning schemes.

I haven't yet seen a UEFI install to an MBR disk. It gives the error we see a lot "Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks."

I rebooted into Windows and ran the Windows version. I ran a Quick test which gave a "Pass" result I will later do an extended test.

As for trying the drive, I had mentioned before, but this thing is getting long. I have tried this drive on multiple computers via USB. I have also tried the same drive, unscrewed from the external case, and installing it internally to my desktop. All yield the same result.

On Drive History
I have had this drive for several years (to the point that I'm not exactly sure when I got it). As far as I remember, I have only used it as a drive for storing large files, like photos/music/videos. I do build my own desktops, so I have swapped drives before. However, this drive was purchased as an external drive. (the model number on the outside of the external drive enclosure is WD6400EB035-01).

Also, I never used any external hard drives for the purpose of booting different OS. I have used USB flash drives to boot dos or android... or to install linux on a different laptop. So, unless there is part of my memory blocked or just plain forgotten, this drive has not been used for booting into any other OS.

I apologize if there are thing I keep not thinking to include. Thanks for the patience in asking further questions.

On File Recovery
As far as drives are concerned, I have others. So, if it comes to it, if I can recover the files, I'm happy.
Thanks for the update - don't know why DOS WDLG didn't recognize the drive WIN WDLG did.
Sorry I missed the other machine tests, thanks for repeating the information.

Good recap

We'll wait for Anshad an jumanji to come on "shift" - they're on the other side of the globe. The long test should be done by the time they log on.

I'll catch up in the morning.

Things are more or less clear now.

1. The OP does not have any special "media device" as such and that he had been using the drive on Windows machines only.

2. Anshad says Partition Wizard will show a mac partition as HFS. I don't know but that is no reason not to believe. I believe he knows better.

3. Now, we know that only some photos the OP/his wife had put in are not there anywhere else and he would like to get those back.

In the light of these how the drive took on the color of a GPT drive or any attempt to rejig the partitions would take a back seat.

PhotoRec would be my answer to recover photos from his drive without reference to the file system on the drive. But I shall wait for Anshad's view and whether he would suggest any alternative procedure.

I did some practical tests and seems that i was wrong about PW. It failed to identify a sample HFS+ volume created by me. Also other popular partitioning tools like "Partition Assistant" and "PartitionGuru" also failed. In my tests, only partitioning tools which can identify HFS+ are Linux "Gparted" and CLI based "fdisk".

To make sure whether the partition is a HFS+ one or not, i would recommend installing the trial version of "MacDrive".


If the partition is formatted as HFS, installing "MacDrive" will let Windows to identify it. If installing MacDrive doesn't helps, i would recommend inspecting the disk using "Gparted" ( there is not a single file system on earth which can't be identified by Gparted). If "Gparted" also fails to identify the file system, we may need to recover the data using "Photorec" or similar software.

Let me know the result after installing "MacDrive" and then we can proceed to the next step.

I would have a look with pguru.

I doubt it is hfs , but for future reference:

Good suggestion SIW2 . "Paragon Partition Manager" will be easier to use than "Gparted" boot disc.

That was a good experiment Anshad. Now we know what doesn't show HFS.

So, back to installing MacDrive and trying to read the drive. If it reads we will also know what is in it.

Curious Anshad, why are you obsessed with this being a Mac drive?
