I bought a new cpu system and used my HDD from my previous CPU, a WD 1TB Green Caviar, as a media drive for the new CPU because I bought an SDD for the OS and apps. Now here's what happened, the tech guy who was supposed to install the OS and drives deleted the HDD during set up in BIOS which he claims was an accident as I told him I have files in that HDD. I asked if the files are still there and he said the files are gone. He said he only deleted it and didn't click format. I asked him not to touch the HDD again and I will just find someone else who can help me with it instead. Now my question is, if the partition of the 1TB HDD was deleted, are all the files gone too? Because I saw that the size of the HDD was at 930+ GB already. He said he didn't format it which I'm not really sure if he was lying. But I have only sat down for 2 or 3minutes after the BIOS opened so I'm thinking it isn't possible that a 1TB could have formatted that fast. If it was formatted, can I still recover the files??
