Toshiba does not provide any proprietary software to manage this SSD. I have this SSD and it has data on 3 partitions. I want to merge all these partitions and erase everything. And also leave 10% for over provisioning. There are no tools on the internet other than parted magic. I got the free version from majorgeeks. Any simpler solution? The best I could find is http://www.toshibastorage.com/SSDKit/ but it's for copying and cloning only i think
