Explained: When to Encrypt your Hard Drive, and When not to

Infopackets Reader Scott writes: " Dear Dennis, I'm thinking of turning on disk encryption for my Windows 10 computer. I've never done this before. Is there anything to be concerned about or to be aware of? " My response: This is a good question. ... The truth of the matter is that if you encrypt your entire C drive using Windows BitLocker or a third party utility, it's going to slow your system down quite a bit. The reason for this is because every single file written to the drive must be encrypted, and then decrypted when read - including your operating system files. Constantly encrypting and ... (view more)

Explained: How to Defrag a Network Drive (NAS or Remote PC)

Infopackets Reader Ron C. writes: " Dear Dennis, I have several drives on my network that I'd like to defrag, but none of the defrag software programs I've tried allow me to defrag a network drive. Any suggestions on how to defrag a network drive, ... or a program that can provide this functionality? " My response: The reason you can't find a program to defrag a network drive is because this is not possible - the easiest way to explain "why" is that the remote drives are owned by another operating system. Simply put: your system does not have permission to move these files around. With ... (view more)

Smartphones Could Replace Cards at ATMs

A British bank is testing ATMs that let customers take out money using their phone rather than a bank card. It says the technology could be safer than using a card because there's less room for hackers to steal details. Withdrawing money without a ... card isn't a completely new idea. One rival bank already allows users to get cash out using a smartphone app that generates a unique code that they can then type in to the phone to get money. The idea is to remove the need to carry a card, for example on a night out. The new system from Barclays would be even quicker to use however, and ... (view more)

Are smart devices a security risk? Security firm Rapid 7 seems to think so. According to the researchers, a range of Internet-connected light bulbs had at least nine security flaws. While the potential consequences are hardly life or death, it could ... be a blow to the concept of smart devices in the home. Osram's Lightify range of light bulbs lets users control lighting via a smartphone or tablet app. The idea is partly to allow more precise controls, such as dimming a bulb or even changing its color, and partly to allow users to remotely access the lights.

Explained: Why You Can't Copy / Restore the Program Files Folder

Infopackets Reader Guy P. writes: " Dear Dennis, A few days ago I turned my PC on and instead of booting into Windows, it went directly into Windows Startup Repair. It scanned the drive but then reported that 'Startup Repair cannot repair this ... computer automatically'. I restarted the system and tried to boot Windows normally, but again it went into the Startup Repair, and with the same results. I backed up my system previously from within Windows but there was no way for me to restore the backup (since the backup program runs inside of Windows). Long story short, I decided to format my hard ... (view more)
