Desperate Laptop faulty hard drive data needs to be recovered

Hello Everyone, help/advice needed please

I have a HP laptop that had 1TB c drive.
i partitioned it into two further drives ( Drive E and Drive F), both had been assigned a drive letter

3 weeks ago my laptops hard drive became faulty and i sent it off to repair with Knowhow. I asked my data to be recovered before they put in a new one.
So what they did was only save what was on my C drive which was hardly anything. and NOTHING of my other two important drives, E,F was saved at all.

I phoned them up and spoke to the IT section and they said they will send the faulty hard drive back and for me to return it back to them via the store with an external hard drive so it can be recovered.

I have been told various things. One said it cant be recovered because the main C drive was partitioned
and someone else said it can be


So i got the Laptop hard drive back again 2nd time from Knowhow saying they couldnt recover but they will be able to if i pay for the extra Service, which makes me think they can recover but want money from me.

So i bought a hard drive to usb adapter and tried to use this to recover.


The problem is that when i connect the adapter, i can hear the hard drive spinning and the light of the adapter lights up. BUT i cant seem to find it anywhere on My Computer, it doesnt get recognised. It is not also recognised in disk management either.


i do regular backups but since begining of this year i have not been able to as i was hospitalised in ICU and everything i did before that i didnt manage to backup and now i fear all that has been lost.



can someone assist me on to get my files recovered please
im desperate
