Issue resolved.

I ordered a new USB3 enclosure and put the problematic drive in it. When I connected it to my daughter's laptop, it booted up fine and all data was visible. Disk capacity was showing as 3TB. All appears normal.

The only thing I can think of is that the power supply portion of the ...

I received some excellent instructions how to change the sector size, but I am not seeing any change in the reported Disk capacity, so I X'd out of TestDisk before hitting OK. Perhaps I need to hit OK in order for the changes to show? Or am I putting my data at additional risk?

I posted about this over on the eight forums as well.

I received this information but don't have a clue how to adjust any options in TestDisk.

UEFI doesn't provide any info about the disk capacity.
Would it be possible that your disk is recognized with 801 GB only?
Before you run any utilities like hdat2, you should run the diagnostic utility from the manufacturer.

Also check Intel Rapid Storage Utility.

Here's a shot from my UEFI screen. It only shows the defective F:\ drive, instead of both my good Z:\ drive and the faulty F:\ drive (based on the name of the drive).

Backup + Desk is my Z:\ drive (USB 3.0 connected Backup Plus). The problematic F:\ drive is connected via USB 2.0 (I have e-sata ...

Ok, let me reboot and check my BIOS and see what it's showing.

I'll be back shortly.

Here's a screen shot after disconnecting my Z:\ drive (my own 3TB Seagate Backup drive).

Looks to me like Testdiskv7 is not seeing the problematic F:\ drive except in the bottom part of the display. Not in the Disk /dev/sbx list.

I don't see how drive f:\ relates ...

Let me try this first: I'll disconnect my good 3TB drive and see what Testdisk sees then. I'll report back when I have a chance to check that.

Thanks for the reply Fiona.

I think the 3TB drive you refer to is the wrong one. I have 2 of them connected. One is the Z:\ drive which shows. The f:\ drive is the one in question. Note above how it only shows 375GB below, but no corresponding entry above. I have no idea what the 801GB/746GB drive ...

My daughter's laptop running Win8.1x64 connects to a 3TB Seagate Backup Plus external USB drive where she likes to keep her photos. Recently, she told me the drive wasn't working. So last night I took a look, and it didn't seem to power up. I took it apart, took the 3TB HD out and put it in an ...
