It's advisable to stress your disk as little as possible.
Should be probably later replaced.
But as long as it gets recognized you can try to get your data off of your harddrive.
Your boot sector diagnose didn't work, because there is no partition in your partition tbale.
That's why TestDisk doesn't list it using "Advanced".
To avoid any further damage, would you like to clone your disk or to diagnose it in the current status?
Please let me know.
How many partitions did you have on your disk?
Might be also possible to create one and having a boot sector diagnose.
Creating a partition would be only in your MBR and your MBR size is 512 Byte.
TestDisk Advanced provides the menu Create Image.
But this Image is only for recovery and not restoring purposes.
TestDisk can work with an image file.
