My harddrive has about 50Gigabytes left so 430 gigabytes is used. But it makes no sense this wasn't the first time this happened. I started checking if my restore point was stil there on regular basis. It starts with about 77MB each and it will be the only one available (I deleted all others before creating one manually)
They grow within 3-4 days to about 135-200 MB max how can it get deleted after just a week or two?
BTW I have a theory.
The last time my manual restore point was gone but 1 automatic scheduled one was there instead. If your system doesn't change will Windows7 replace the manual one with an automatic one but delete the manual one if it contains the same information?
Otherwise I'm friggin baffled and pissed at Microsoft. What good does it do when you rely on restorepoints but they easily dissapear?
i dont use system restore on my ssd--i make an image to an external drive
but if 430gb of data is used it may be that its deleting restore points to make new ones
have you looked in System Volume Information folder, which is a hidden system folder on the root of c drive
