Hi just wanna inquire I have a 1TB hard disk back from 2009, recently gor corrupted while steam installing dota2.

I tried reformatting but windows wont allowed it, so I tried partition guru to verify and repair.

Now after partition guru verify and repair,when I tried to reformat the MBR is missing during the first reformat.

I tried with all the available options of partition guru trying to reformat my hard disk, now it wont even be able to read anymore it says some error with memory allocation error.

Now my question is, is better to send to a professional to fix it or just purchase a brand new one? or is there any other DIY tools to fix it?
