Question usb to internal drive

[Wadealow]

I have just built a new pc and I have a 4tb usb external hard drive that I decided to remove from its box and use as an internal hard drive on the new machine to save space on the shelf and keep the noise down. However, I wanted to keep the data already on the drive, but Windows on the new pc is asking me to reformat the drive and wont recognise the files (presumably because the file system was set up the work with USB). Is there a way to avoid the laborious process of copying the files to another drive with the usb reconnected, then reformatting the drive, before copying the files back? The usb drive was formatted as NTFS, but all windows is now seeing is a RAW partition.

if windows cannot see it the enclosure probably encrypted the data, and the enclosure should be able to access it. if so you need to replace in the enclosure, copy data off, remove from enclosure and then format.

Not the answer I wanted, but I was kind of expecting it to be something like that. Thanks for the response.

Encryption would be my guess as well.
