i lost my 180G data in 200G hardisk. i tried R-Studio and managed to retrieve the data back. Unfortunately, not all recovered. some files corrupted. Especially my precious pictures but better than nothing

now, another prob get in. when i tried to copy files into the hardisk from other PC, it seem all success.
but when i pluged into my PC again, the data wasnt there. no space usage of hardisk. but it's actually there when i scanned with R-Studio.. y ma??

Yes. I've format the hardisk. there are 2 partitions. 1 i format with quick format and another with regular format. if the problem caused by that "quick format" partition, why is it affect the "regular format" partition 1?
