Hello,
I've searched the www but did not found an answer...
Last post on this topic dates back 2015
So,
My ext. backup HDD crashed after a bad micro-usb connection.
Seagate Desktop HDD 4000GB
It was connected via a USB3.0 hub to my laptop (WIN10/64)
Switched cables etc but it only shows as a USB-device without name or station.
So I took the HDD out of it's case and placed it into a dockingstation that goes ito my laptop via USB2.0
Now it's given a Station letter but I get the popup "Drive needs to be formatted, format now?"
NO !!
So I ran TestDisk but I got the message:
The harddisk (2199 GB / 2047 GiB) seems too small! (< 4000 GB / 3726 GiB)
Also telling me this should be fixed first.
Can someone tell me How to do this ? Without loss of data
Log can be found below
Thnx in advance !

If your drive came with an external case put it back there and rerun Testdisk. It looks as if the case electronics emulates a sector size of 4096 byte.
The file system size above is roughly 1e9 sectors according to the NTFS data found.
1e9 sectors * 4096 byte / sector will give approx. 4e12 bytes which are the 4TB of your drive.
