Toshiba Satellite L755-S5306

Alright, I just signed up here because I need help with something, I'm not sure if I'm posting this in the right place, so please forgive me. Also, I'm kind of a dunce once it comes to computers, so you guys will probably know tons more than, so hopefully I don't annoy anyone.

Anywho, onto business. I scanned my computer using Avast! the free version, and I noticed that it had scanned a little bit over 500G's of data, which I realized to myself was impossible, since my hard drive says it has a maximum capacity of 449G. I thought that was strange so I looked up how much space my computer SHOULD have on Toshiba's website, and it said that my computer should have a 500G harddrive. So now I'm confused, I can't find any sort of secondary hard drive at all, and the only other thing in my "Hard Disk Drives" Section is this Microsfot Office Click-to-run 2010 (protected) Q: I checked that out and it said it has 0 bytes, so I'm pretty sure that the missing 51G isn't hiding in there.

Besides that fact, even if I do have the missing 51G's somewhere, there's still the fact that my Avast! managed to scan over 500G of data.

So, I guess my question is, did I do something wrong with my computer? It is broken in any way?

Well, Sebastian, lots of folks have that question so don't be embarrassed for asking. You will have to ask Avast how they manage to scan more than is there.


Windows says a Gb is 1,073,741,824 bytes while the manufacturer says a Gb is 1,000,000,000 bytes. The manufacturer is going by the metric system and Windows is going by a computer design standard.

So on a 500,000,000,000 byte drive the
Manufacturer calls it: 500,000,000,000 divided by 1,000,000,000 =500Gb
Windows calls it: 500,000,000,000 divided by 1,073,741824 = 465.66Gb


You can see then that you really had about 466 GB to start with.  And with Toshiba computers, there is a about 1.5GB partition which controls the HDD recovery process and about a 15 GB partition that is the full back up of your out-of-box computer. 466 GB-15 GB-1.5 GB = 449.5 GB for your C Drive. You can see the exact partitions on your machine by typing Disk Management in your Start/Search box and then clicking on Create and Format HD Partitions. That will open Disk Management showing all partitions on your HDD.


You have nothing to worry about and even the Avast count may be an anomaly that doesn't occur again. Now, enjoy your computer!

Just to clarify a bit more, that difference is because the drive manufacturers talk in decimal while programmers talk in binary.


The number above is 2^30 instead of 10^9.
