Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

Lost data from hard drive, what to do now?

Well, I'm sorry to hear that it's a WD My Passport that failed on you, @tomhenry ! *Frown
I'd recommend you to try using a different USB cable with it and see if that will help your system to detect it without it disconnecting.
I'd also suggest you to go to Disk Management and see how the drive is listed there. It won't hurt to check up on the health and SMART status of the HDD by running the QUICK and EXTENDED tests from the WD's Data LifeGuard Diagnostics. Here's a link to the available software: http://products.wdc.com/support/kb.ashx?id=11ZOpD

Give these troubleshooting steps a try and keep us posted with the results!
