in earlier, i have 500 gb hdd. 365 for data storage, & 99 gb for system. some times i wan to divide the partition from my 99 gb system partition with disk manager. and it work nice from 99 gb to 50 - 50 gb partition. but when i want to do the same thing on 365 gb partition, all of my data and this partition get lost, and this partition is lost too. not like earlier. And i recover it with easeus data partition recovery. now i want to take back my 365 gb partition. is it safe to do withour losing data on 50 - 50 gb partition? because i think this is same hdd. I want to try with software partition recovery. but is it safe without losing any data on earlier partition? Please help.
