Disk appeared as basic in disk mananger but as EFI GPT in Test Disk

#1 Post by Gorf »

My drive doesnt show any files, gives i/o errors and now is unknown unallocated in windows disk manager, cant make a chdsk
I tried TestDisks, gives as options PC/Intel and EFI GPT, but the app recognice by default my disk as EFI GPT but windows told me was a basic disk which means should be MBR, which i think it is the Intel/PC. I ran aeseus app and tells me it is MBR, what should i do? I tried to initialize the disk to GPT which was RAW but i think didnt initialize as stayed RAW and basic and then changed to unknown unallocated for no reason and now says it is not initialized.
Also my disk is 4TB and i heard MBR is max 2GB, so it is GPT? MBR is the same as Basic disk?

I opened Disk Manager in windows and tells me the partition type is "not applicable" instead telling me if it is MBR or GPT

I give more information of what happened

I have Seagate ST4000DM004, which has 4096 bytes per sector https://benson.ph/products/seagate-barr ... hard-drive and a capacity of near 4GB that started to fail, appeared as RAW randomly at start, some times the files appeared when was not RAW and i could recover data from the disk using robocopy, but was slow and worked randomly.

Then used live Ubuntu CD 21.01 i think was the version and i used sudo mount diskpath mountpointpath in home, i mounted several drives, this seagate, another HDD and a SSD, the seagate didn't let me access and got this error message if i remember well "The NTFS partition is in an unsafe state. Please resume and shutdown Windows fully (no hibernation or fast restarting), or mount the volume read-only with the 'ro' mount option.", so i used ntfsfix, which let me access the drive again. Then i access the other HDD with mount and started to click all the time even though i could see the files anyways even though didn't let me copy any contents on it but allowed me to create new empty folders and when i logged in back to windows i couldn't even initalize this drive, just appears the option to initialize and once i try to initialize gives me an error. Don't know what to do with this disk as seems to be just a brick, even though worked before using the mount in the live CD

After trying many apps i decided to initialize the ST4000DM004 disk to GPT, but seems it failed as in disk manager tells me it is Not initialized and is unallocated. Says the disk works fine even though is not true

Now i don't know what partition type should i choose in TestDisk, Testdisk selects by default GPT but don't remember making a GPT disk, and all other disks i have are MBR. Also the app easeus partition master tells me it is MBR. Besides the disk is of 4TB and had just one partition, in theory should be GPT but also MBR as has 4096 bytes per sector instead 512 bytes as i read here https://www.reddit.com/r/ps4homebrew/co ... _than_2tb/

So as i tried to initialize to GPT now i have no clue if it is GPT or not even though the initialization didn't finish maybe changed something

I ran a Seagate DiskWizard app and gave this information of the disk, the disk appear as type "Read", not MBR or GPT, seems it is just readonly though diskpart don't find the disk
