Moving USB 3.0 Ext Hard Drive to Internal?

[Nate McGraw]

I ran into an issue, that I didn't think would be one.
I've been using an External USB 3.0 enclosure for a 2TB Hard Drive with an NTFS file system.
It's my media drive, I thought I'd be moving it around, I haven't so I would like to put it in my system. When I removed the Hard Drive from the enclosure and mounted in side the computer, I started up the system and the Hard Drive was their but not accessible. I viewed the Disk Manager and noticed the file system was now RAW. I restarted the system with the same out come. I then removed the hard drive and re-enclosed it in the usb 3.0 enclosure. The 2TB hard drive was once again viewable to the system.
Is their a reason the system would see the Hard Drive as RAW when installed internally but not in the original enclosure?(This was a third-party enclosure, the hard drive did not originally come with the enclosure) If anyone has thought I'd really appreciate it. Thanks.

It could be that your enclosure itself has a small boot manager on it that tells the computer what type of drive it is, and when you remove the enclosure you're essentially removing the drives "about me" section. If this is the case, you won't be able to use the drive internally unless you reformat it.

Something like that was what I was afraid of... Moving 1.25TB, is not going to be easy. Thanks.

Yeah wish I could say there was an easier way to do it, but I can't think of any.

The bridge firmware in some external enclosures is configured with 4KB sector sizes. When you remove the drive from the enclosure, you expose its native 512-byte LBAs. In Disk Management you will then see partition sizes which are 1/8th of their actual size.

Alternatively, some enclosures (eg WD My Book Essentials) incorporate hardware encryption, which means that your data will be gibberish.

You can see what is happening by examining sector 0 with a disc editor, eg DMDE (freeware).
