1 TB=931 GB: What I learned from my first portable Hard drive

Got Western Digital® My Passport® Essential™ SE 1TB Portable Hard Drive-USB 3.0 as my very first portable hard drive because my backup Fantom Drive decided to die when I was away from NYC.

After this portable Hard drive, I might have to consider getting a secondary backup drive since what went with the death of the Fantom was my life between 2007 and 2010... (Thank God that I didn't really get too much done during these 3 years and, speaking of memory dump. 8-O lol sigh)

I decided to not install the WD Smartware backup software because a lot of people out there seem to have complaints about how this software slows their computer down.

The problem I have with the drive is that, although it claims to be a 1 TB drive, you only have 931 GB available to store your files.  Ended up, this is something that gets many people really confused--- not only me.

So said them smart people... 1 TB can be 931 GB. 8-O

It all depends on how you classify TB.

Essentially, the Hard drive vendors use decimal numbering system while that used by the operating systems, binary.

1 TB in decimal numbering system = 1,000,000,000,000 (10^12) (Base 10)
1 TB in binary numbering system = 1,099,511,627,776 (2^40) (Base 2)

Since the operating system counts in binary, 10^12 equates to around 931GB.

1TB = 1,000,000,000,000B

931.32*1024*1024*1024 =931.32*(2^10)*(2^10)*(2^10)=1,000,000,000,000B

Thus, 1 TB=931 GB

Tricky and guess this is why they teach us math in school... 8-O lol

How do I like this hard drive so far?

Well, it's been trying to back up my system containing 120 something gb of data... and only up to 30%... for the past 3-4 hours or so while my mom and I are busy packing...

Don't know who I should blame--- Windows 7 backup or the drive..... zzzzzzzzzzzzzzzzz....

--unless simply the fact that no USB 3 port available on this hard working machine...
