320 GB HDD's entire partition deleted...HDD showing unallocated

#1 Post by Ronyk » 14 Sep 2019, 05:58

Hello Experts,
I'm using an assembled desktop containing 2 HDD's, 250 GB & 320 GB(collected from a laptop).
320 GB was my primary HDD containing OS(Win 7) & 3 other partition to store data, where 250 GB HDD was my secondary HDD with 3 partition just to store data.
This was the scenario for last 6years(never formatted during 6 years)

One day while working on VMWare I had to reboot my system but, strangely system was stuck on "logging off"....so I decided to force restart.
But when I did system never came up...got the message "Select proper boot media". HDD were getting detected in BIOS.
Then I decided to install OS on my secondary HDD(250 GB). Shockingly what I found, My 320 GB HDD has no partition & asking for "initialize" in disk management.
After Initialize I used "testdisk-7.2" to scan & getting the following error...."file_pread(5,2,buffer,119(0/1/57)) ReadFile The request could not be performed because of an I/O device error.

"

What should I do...plz help...My contact number is 7003746325

You can try to clone the disk to a new empty using ddrescue as described in https://www.cgsecurity.org/testdisk.pdf
But it's highly recommended to contact a data recovery company to deal with this physical problem.

Could the cloning trick cause further damage in a case like this?

Yes, reading from a physically disk may further damaged it, it's why it's highly recommended to contact a data recovery company.
