Nov 20, 2014   //   by Crocmaster   //   Geek Speaks  //  No Comments

It’s happened to all of us. You step away from your computer and come back a few minutes later. While you were gone, your computer’s hard drive lights start flashing — but what exactly is it doing? It’s natural to be a bit suspicious.

This is generally nothing to worry about. All normally configured Windows systems will do this regularly. Malware is always a possibility, of course. You can run an antimalware scan if you’re worried.  Read more >>

Set up a new disk on Windows 8.1 or 8 and you’ll be asked whether you want to use MBR or GPT. GPT is the new standard and is gradually replacing MBR.

Windows can encrypt entire operating system drives and removable devices with its built-in BitLocker encryption. When TrueCrypt controversially closed up shop, they recommended their users transition away from TrueCrypt to BitLocker.

BitLocker Drive Encryption and BitLocker To Go require a Professional or Enterprise edition of Windows 8, or 8.1, or the Ultimate version of Windows 7. However, the “core” version of Windows 8.1 includes a “Device Encryption” feature that works similarly.  Read more >>
