SSD missing over half its space

[GiantDwarf01]

Hi, I have a 1TB SSD that's currently only showing less than 300GB of space. I recently reinstalled win 8 onto it, but before that it was working perfectly. I do have another 1 TB hard drive installed (not SSD) that's for my storage and that's working fine. There's no partitions other than for the system, but that's only a few GBs. Any idea on how to fix this?

Thanks.

How to fix depends on what the issue is. What is taking up 700GB of space?

Possibly one of the visual drive space analyzers can point you in the right direction. WinDirStat, maybe.

Nothing's taking up the space, everything I check says the drive has a max of 300GB total, which means I have 188GB free after installing windows.

I'm not sure if this means anything but when I go to optimize drives in the defragmenter, there's a 3rd drive labeled "\\?\Volume{13c674f6-5c55-11e3-be65-806e6f6e6963}\" that's supposedly a solid state drive as well. Is it possible that's what's hiding all my GBs?

I would say is probably it. Why is it there? Unknown.

Yeah no idea where it came from. Any idea how to remove it and give the space back to the c drive?

i just signed up here to share my solution to the same problem that happened to me and i couldn't find anyone mentioning it any where, i lost a lot of time between formatting bios booting and played around everything so here is how i solved it
the reason of the ssd lost size that's almost 50% of it's size was intel rapid storage cache technology all i have to do is open intel rapid storage technology software and disable acceleration from performance tab then i was able to free the 60GB and it appeared in the disk management as an allocated space i extended the primary partition and was able to use the whole 128 GB ssd space again
