[HELP] SSD - The Unknown Space

[eD|t|0n]

Hi Peeps,

I have a mid-2012 Mac mini. Recently upgrade to a 128GB SSD (Plextor) and following is done

1) Create Bootcamp with Windows 7 Pro. (Partition 70GB)
2) Install apps like Office 2010(Words/excel/powerpoint/outlook), Adobe Acrobat, Teamviewer, Winrar, Google Chrome, VLC. So you can see it's basically for work only.
3) All the installer exe. file does not exist on the SSD.
3) Based on system properties, used up only 30++GB only.
4) Within few hours, I'm left with only <1GB of space and system keep prompting me low memory etc etc.

I thought it was my fault hence I rush out to purchase Samsung SSD 840 Evo 256GB and repeat the whole process as above.

1) This time I created bootcamp with windows 7 Pro (Partition 180GB)

Same thing happen again after 2 days. I don't believe my eyes when the same applications above can take up so much space when I almost doubled the partition space of the boot camp to 180GB. Still the same prompt that I'm left with <1gb of memory.

I ran disk cleanup, defrag(Not good for SSD) but I still can't find what is hogging the "Mystery" space....

Anyone encounter this kind of issues? Please assist me in heading the correct direction to resolve. Thanks a lot..

Do you have a screenshot of this prompt? is the prompt within OS X or windows OS?

You can use 3rd party programs to identify space-hogging files, I've listed a couple below.
I'm not much a windows user so i only found 1 for you.

OS X: Omnidisksweeper, DaisyDisk, Disk Inventory X
Windows: Scanner

After since, I just reformatted the bootcamp and reinstall and repeat the whole process again. Getting tired of this. Anyway I took a snapshot of this before anything happens.

I have 143GB of space left and hopefully it stays this way. Will update again if the sudden lost of space occurs and i will snapshot too.

It is SSD disk space. Sorry that I used the words interchangeable. But I'm referring to the SSD disk space all along. My mac mini specs is mid 2012, only upgrade I have done is this SSD and also ram which I push up to 10GB.

As my previous post, I attached a snapshot which I just reformat the whole bootcamp and reinstall the programs. What you see on my desktop is whatever I have install. That's it. No installer files exist on the disk space. So basically I have 143gb of free disk space as of yesterday.

I hope this disk space of 143gb will not become <1gb and warning prompt will appear again. I'm very afraid.

Have you enabled TRIM for your Mac or install Onyx to "clean up"? SSDs have to constantly move blocks around to consolidate the valid data, and delete invalid blocks to keep plenty of empty space available for when it’s needed. This process is known as Garbage Collection.

hmm if e hdd free space drops drastically again u can use this to check

TreeSize Free Portable | PortableApps.com - Portable software for USB, portable and cloud drives

Can you open iTunes and check the space usage? Is it a huge bar called "others"?

might be windows updates? if you haven't updated for a long time, might have 200+ updates, then the windows SP1 update which takes up quite a bit of SSD space...
