Watch Hard Disk Drives Being Made

We rely on hard drives to store our data for us and we use them every day, but have you ever wondered just how they were made? This video, courtesy of How it’s Made, shows you how a hard drive is put together from start to finish.

Solid State Drives: Why You Need One

As we go over the long list of specs on a new computer we usually gloss over our storage options and focus more on processing power and memory, and for good reason as our storage options haven’t really changed much over the years.

Now, a new option has arrived on scene, Solid State Drives (SSDs). Solid State Drives are a whole new beast and they have a lot to offer. SSDs are comprised of multiple flash memory chips that are all connected together.

Being comprised only of chips means that Solid State Drives contain no moving parts and unlike the Hard Drives we are used to using, are completely silent when in operation. We can finally say goodbye to that grinding sound we hear everytime our drives spin up, but to their credit they have become much quieter over the years.

What makes this technology so amazing is its speed. SSDs read and write data at such blazing speeds that on some systems, can make Windows load faster than the animation that plays during boot up. Load times in games are reduced drastically and content loads much faster though out the whole system. It really shows how much of a bottleneck our old Hard Drives were.

However, it took me a while to build up the courage to buy one and put all my data on one these new drives. When SSDs first started to pop up in stores there were many problems with the firmware installed on these drives, some of which could result in a complete failure of the drive itself. Another issue was price, it was hard to justify the cost per GB. SSDs that have been on the market for a while now and a lot of manufacturers seem to have worked out alot of the bugs that plagued early SSDs. SSDs are becoming much more popular, in fact SSDs are now being installed in the new Macbook Pro (retina), and performance gains are obvious

Prices are still not nearly as cheap as the old hard drives but there are many deals going on right now as companies and retailers are trying to push the world towards this new storage option. Still think its a bit to pricey ? No need to worry, as consumers buy more of these drives I expect to see prices drop again.

I did remain skeptical for a long time about how much performance gain I would really see until I just jumped in and bought one of these drives. If your curious as to how my experience was, let me just say that once you buy one of these you will probably never go back.

How To Erase a Hard Drive

August 18, 2012 by Richard Vincenti Jr Leave a Comment

So, you have finally decided to throw out, sell, or give away some of your old hard drives and you want to make sure what ever data you had stored on them is completely wiped out. Well, I’m glad you have made the smart decision to protect your sensitive information but there are a few things we need to go over before we wipe everything clean.openHarddrive

Please note that the process explained in this guide will completely erase your hard drive, unlike formatting which basically makes the data invisible but not completly gone. With formatting, data can actually be recovered by using special software.

So you want to nuke it all, let’s get started.

1. Backup anything stored on the drive that you want to keep, as you will not be able to recover it once this process is completed.

2. Download a program that is made for destroying data. The one I will mention in this guide is DBAN which is a free and powerful tool.

3. Following the instructions provided on the DBAN site, burn the iso file to a disc.
**Do not modify the file at all or it may corrupt boot disk creation.

4. Once you have created your boot media by buring the DBAN iso file to a disc, insert the disk into the computer that contains the hard drive you would like to erase.

5. Boot the system with the DBAN media, if this dosen’t seem to be working you may have to go into the settings of your BIOS. You can usually access your BIOS settings by pressing, esc, delete, F1 or F2 right when you power on your machine. Once inside the BIOS settings make sure to change your boot order to allow your system to read from your optical drives before your hard drives. Then be sure to properly save your BIOS settings before you exit.

6. After DBAN is running you can follow the on screen prompts to complete the cleaning process. I would recomend running DBAN in interactive mode which will allow you to change the method in which DBAN will erase data. In interactive mode you will see a menu at the bottom of the screen. Press “M” to change the method. Each method has a decription of it wipes a hard drive and the security level it has been given.

7. Choose a how you want to verify passes to enusre the proper removal of data.

8. Start the wipe process. Usually “F10” in the menu.

** Please note that it can take anywhere from just a few minutes to many hours to complete this process depending on the storage capacity and method used to wipe the drive.

If you have any other issues getting started please refer to the DBAN webite and navigate to their help section.
