ok im running windows 7. im using testdisk on a drive that is inside a docking station. its an 8tb drive seagate.

my first issue was that windows wasnt seeing the full drive but i got that sorted by going into management services or whatever its called.

heres my real issue. the hard drive asked to be formatted while in use so i ran teskdisk because from what iv gathered chkdsk doesnt do RAW.

i followed this guide http://www.tomshardware.co.uk/forum/263779-32-change-file-type-ntfs

 

but im stumped now. iv taken photos of the problem this was the first error

I'm not sure how to proceed. Your first image says it all. Testdisk cannot recover the partition. What computer did this drive come out of because Testdisk is saying the drive has a Mac HFS file system. 

 

You said the full drive was not detected. What did you do in disk management to affect the drive capacity?

this came from a windows 7 machine. its never been a mac.. although i DID buy it online someone could of tried to pull or did pull a fast one on me

it came from amazon

 

when i originally stuck it in it was only seeing 1.27TB of 8Tb so i went into disk management and i think i remember having to set it to logical.

im not 100% sure on this

 

im gonna go look for the guide when i get home.

Do you mean the computer it came out of? Do you need any data off this drive? The problem is if the computer you are trying to install this 8TB drive is an OS disk and the computer has a legacy BIOS you will have issues booting. An 8TB drive would need to be formatted as a GPT disk in order to access the full disk which requires a later computer with UEFI vs Legacy BIOS. 

 

Is this disk being used to install an OS on or strictly a DATA disk?

Do you need any data off this drive?

I think the only way you will get data off the drive would be to scan it with PhotoRec or some other data recovery software. The problem with PhotoRec is recovery is done in real time and all files will have generic names. It does allow you to select extensions to recover using the file options. Other data recovery software requires you to purchase a license. PhotoRec also recovers to the the folder you unzipped it to which means you need as much free space on the recovery drive as what your intend to recover.

 

http://www.cgsecurity.org/wiki/PhotoRec_Step_By_Step

 

Open a command prompt. Type the following commands.

 

diskpart

list disk

 

What size is shown in GB for the external? 

 

If you do not need the data you can wipe the disk and reformat the drive. It can be done in diskpart but would be easier in Partition Wizard doing the following steps.

 

Select your External drive in the UI. 

Delete All Partitions

Initialize GPT

Create any number of Primary Partitions in the unallocated space.

 

All steps in Partition Wizard are virtual and will not complete until Apply is clicked. This will let you back out if you did an error.
