Drag and drop on the same disk, same partition hours. Why and how to fix it?

Hello

My computer crashed and I put the files saved on the disk. Slide it / move files adobe is 500 GB and taken a few hours to complete. Drag and Drop that into a subfolder in this directory, the system tells me that it will take even more time to copy. Why? What it means.

Two things you need to know:

(1) the system hangs usually about all six months requiring a clean install.

(2) this time I portioned disk, put the operating system on the partition of 500 GB and put the data files on the other half of the partition to see what happens the next time it crashes - and it will eventually crash. (I want to know if everything is damaged remains on the side with the operating system or if it affects the entire drive.)

All other files seem to drag / move very well, it is precisely those specific files of photographs. Any suggestions? This allusion to a problem not diagnosed with the disc? Is it because I partitioned the HD?

Thank you

What exactly happens when it crashes? Describe what you saw when it happened. For example, the Mac does not fail to start? Are icons or messages displayed?
