Disk "Not Initialized"

[seagate18]

Hi,
I'm having a big time problem with my Seagate 3000GB external HDD. It was starting to run slow, so I was moving data to an external SSD. I thought that maybe the powersupply was going, so I removed drive from it's housing and placed it in removable HD slot on my acer Predator. Here's where I think I messed up - I booted computer up with the drive inserted and I think computer didn't recognize drive as a bootable drive and it added script (disk.inf) to MBR or partition?? Device manager / disk management sees drive but says it is not initialized. TestDisk Quick Scan doesn't see HDD, nor do a number of other utilities. Some do and say that the disk is not accessible. Any help would be greatly appreciated. Thank you.

Removing from the enclosure, and now it shows as Not Initialized is quite normal.
If you Initialize and then format, it will work.
Of course, this wipes out whatever data is on it.

If you put it back in the enclosure, it will probably work.
Being "slow" is a whole different problem.

I did that and it's the same when connected by USB. Something definitely happened when the computer was booted and drive was in machine, as seen on the event description screenshot. Thank you for your service USAFRet !

Well, you could hit Initialize, and then Format.
This will, of course, wipe out whatever data is on it.

Or, the drive may be dying.

There's still ~1TB of data that I would really like to save. Have you ever used data recovery services?

No I have not.
This doesn't help now, but for future reference: http://www.tomshardware.com/forum/id-3383768/backup-situation-home.html
