Samsung Performance Restoration: Did you end up w/ less space?

[snovvman]

I ran the Samsung Performance Restoration on two of my 840Evo 1TB SSDs on two different computers. Upon completion, one drive ended up with around 28GBs less space and the other around 13GBs less. Both drives are partitioned. It is the boot partition that lost the space.

As far as i can tell, the partition size has not changed, but I have no idea where the space went. I searched for large files and recent files but didn't come up with anything obvious. Does anyone know why, and if I can get the space back?

Thanks.

My go-to tool in such a case is always Windirstat. It gives a lovely map of where space is used on the drive.

Well, first empty the recycle bin and see if that helps!

I love WinDirStat.

another good one is TreeSize Free. It can access "hidden" files and folders that WinDirStat just shows as Unknown. Even when you give it full Admin Privileges.

Thanks. I am familiar with WinDirStat. I have already went through disk cleanup, CCleaner, and WinDirStat. Nothing is out of the ordinary. Needless to day, recycle bin is empty. I can't be sure that the partition size did not change. Are there any known conditions where Samsung Performance Restoration's aftereffect is reduced storage space?

I just saw another thread where over a hundred GB of SSD space are listed as Unknown by Windirstat. The only case I've ever heard of it failing to shine the clear light of day on the disk state.

there was a thread here on tom's with a link to another report that i can't find but i'll give you the Fred Flinstone reader's digest abridged version. Basically the performance restoration utility is correcting for storage cells where the electrical charge has diminished or degraded, making the controller take an inordinate amount of time to read those cells when called on - the performance restoration utility is copying those weakened cells to other cells. The report said it copied them termporarily but i do not recall what it did with them after that.

it might be interesting to fill the drives remaining free space with a few large video files or other large files, then delete them and see what your system then reports for "free GB".

fwiw
