Why are my SSDs Smaller once Installed??? And dont know if my anitvirus is catching everything

post #1 of 6
Thread Starter 
I just installed two SSDs in my new machine and when looking at them in windows they are both smaller than what i thought i was paying for. One of them is supposed to be 256GB and it is showing 238GB the other is supposed to be 128GB and it is showing 119GB. What happened??? here is a screenshot..



Also How in the world am i supposed to feel safe with all these files in the System32 and SysWOW64 that i have never heard of and i cant even delete most of them because i have to be the "trustedinstaller" user... I am the only user on the pc and i am the admin why wouldn't i be able to delete them??? I installed ESET 5 thining it was a really good antivirus and when i run scans of everything nothing bad shows up. should i trust this???doh.gif

that is normal. HDD are rated for 1000M = 1 G not 1024M = 1G. you need the system32 and SysWOW64 (Windows on Windows 64). DO NOT DELETE THEM. your system will most likely not boot if you do

Read up on the difference between mebibytes and megabytes. Drives are in megabytes, windows measures them in mebibytes. Stuff in sys 32 is good. Don't delete any windows stuff.

1 KB = 1000 bytes in hardware terms

1 KB = 1024 bytes in software (formatted in windows)

It's a damn conspiracy I tell ya!

Oh dear.

1. Hard drives and SSD's are advertised as a certain number of gigabytes, using thousands. That is, a 1TB drive is actually 1 trillion bytes. But because a computer is binary, it sees 1 trillion bytes and divides by 1024 and then 1024 again which shows 953 Gigabytes. SSD's do the same. There is nothing wrong with how it is displaying.

2. Don't touch files if you don't know what they are and what they do. System32 is the core of Windows. Deleting values in there generally will destroy the OS. TrustedInstaller is the Microsoft way of saying "HEY! Don't touch this or your system won't boot!"

3. ESET 5? Scrap it and get Microsoft Security Essentials if you're in Windows 7, and nothing in Windows 8 (It has WIndows Defender which is basically integrated MSE)
