|We seem to going round in circles?|
In a situation where one is considering how to recover data from "any" hard drive or ssd... one does NOT write anything to the device in question; nor reformat it.
The drive is either connected via usb to working computer, or attached as a slave to one. The recovery software is run on the working computer, and the drive in question accessed etc. from the working computer..
Any recovered data is either stored on the host computer, or on another external hard drive.; and later of course to dvd for "safe(r)" long term storage/safety.
Your choice at this time is surely which utilities to test, and then decide which to buy...?
I would test more than one - and at risk of repetition, even pedantry... - do not write anything to the problem drive, nor reformat it.
