My Hard disk can never run out of space?

This is really weird.

So I have a 1TB HDD which in reality only has 931GB of space (I know why that is the case, lol, different story)

Until yesterday, I had occupied some 929.7 or 929.8 GB of it, so that My Computer only showed about 1.2 GB of space remaining.

Now I know a lot of people say you should always make sure there is at least 15% of free space left, but my computer didnt start acting weird or anything.

That being said, I restarted my computer today morning and noticed that suddenly, it says there are 8.76 GB free now, even though I have done nothing in the time period between yesterday and today.


I have noticed this exact same behavior on my laptop too - whenever my hard drive seems to get full, after a couple of days, some extre free gigabytes appear out of nowhere.

I conclude my research with the finding that the reading of how much space we have in our HDD is actually buggy and faulty, and that we should not trust Microsoft's measurement tools.

If our HDD was really that full, we simply would not be able to download more stuff, getting warnings etc. While this warning does appear if we want to install a program that requires many GBs and our HDD doesnt have that much; data that acumulates on a daily use such as downloading pics, e-mails, music files, etc. can be done even if your Hard drive is full, and in reality your HDD is not full at all, as in the last moment, new space appears our of nowhere.



By the way, I have shadow copies turned OFF, so I doubt Microsoft had cluttered my HDD with backups and is simply deleting them to make space when needed.

Cheers and long live the miraculous HDD technology,

hi,

System restore and other MS function hide some data that can only be accessed by special means.
I think it probably has purged some system restore and such because they became old data and would not be needed anyway.

I don't think your HD is defective nor Ms software buggy.

You can download hard disk sentinel trial and see what it tell you.

I usually clear temp files about once a week, and no more than 200MB of data accumulates during this time...so, suddenly 7GB of free space? Weird. I also always keep the recycle bin empty.

I hope it hasnt randomly deleted files from My Pictures or My Documents, but I wonder whether there are any articles about this subject.

Is there a way to detect how much System Restore data my OS has "reserved" on my HDD? Does hard disk sentinel tell me that?
 
In disk cleanup, select the "more options" tab. Click the "cleanup" button in the system restore section. This will delete all but your last restore point. Just make sure you don't have the need to restore beyond today as that will most likely be the last restore point.
