Does the computer still boot with the original drive ?. Trouble is when you plug a hard drive/storage device into windows, it writes something to somewhere on the drive, thus it will not boot after ( haven't figured what and where yet ! ). However Linux Mint has 2 programs that perform block by block copies, DD, and DDrescue, they are a bit difficult to 'drive' unless you can cope with command line instructions.
I recently bought a Tek scope which had the classic IBM 10G hard drive. I had an old PC running Linux Mint 18, which I had used to back up drives for my R & S FSIQ 26 analyser some time ago onto a Compact flash card in a CF to IDE adaptor. There was a GUI version available that made things a lot easier.
I tried to use it to program a M2 16G drive in a standard cheap 'n chearful caddie to make a copy of the HD, however Mint 18 had problems detecting things, or maybe the machine was not powerful enough, or motherboard was too old ?. So I dug out another no longer used PC with GA-MA785GT-UD3H motherboard, with athlon 2 and 8G ddr3, and installed Mint 20.3. Only problem here was some MBD's will not boot from USB so its a pain trying to install software from CD or DVD.
I then bought DDrescue-GUI, cost around £5 so not a lot. This gave me the tools to copy the old system HD. OK it is not as easy to drive as Windows, but it gets the job done without having to 'phone home' every few minutes. Having IDE and SATA slots, it should cope with any sort of drive, and its the machine you can stick away in a corner at very low cost for the next time it is needed. Net result is the scope starts much faster, and if the M2 drive dies, I have an image file so can make a copy easily.
Works for me,
