Help Getting an Encrypted Hard drive to read

Hello I am new to Windows 10 and was pretty much forced to change over. I had a windows 7 laptop that I took into my local computer shop and when I got it back they had swapped out the 1TB Barracuda hard drive with a smaller one. they told me it was encrypted. I dont recall or even know how to encrypt it but I would like to try and access it and see if I can figure out the password. I have a 2.5 HDD enclosure that I have had around and this one fits the hard drive. when I plug it in to the laptop the hdd lights blue but there are no pop ups on the laptop installing and it never shows on my pc.

Like I said I am very new to 10 and have tried googling but nothing worked. the hard drive itself was less than 6 months old.

Im not sure if it matters but the old laptop was hp as well DV6000 entertainment pc windows 7 now i am using a windows 10 hp.

thank you in advance for the help and I look forward to learning windows 10

First job is see if it is encrypted you can do anything until you know for sure you can read it

Hello thanks for the replies, I had taken my windows 7 laptop in and they told me that the hard drive had gotten encrypted and they said that they couldnt do anything so they had to put in a smaller one. they said that it was accessible and I could hook it up and use it like a passport.

I have the enclosure and hooked up the HDD to windows 10 and it will not read. It lights up but there are not pop up and it doesnt show under the my pc. I did find an article about disk management but it didnt show on there.

I never had ransomware on my old laptop, i had only taken it in because when I did a windows update and it restated to a blank background and the icons were not viewable unless in the large format. it only was suppose to have the software reloaded like before. I took it to my regular people and they wiped the entire laptop with nothing but a few files on it. I am trying to access the HDD to see what programs and personal files I have on there but it will not read.

they put it in a little bag when i picked up the laptop and I put it in the enclosure. I have the original laptop still so I will try and hook it up there.

im not sure what you mean by "clean " or reformat I was just told I can hook it up like I did with anothe HDD. I will report back once I try to hook it up to the original laptop and see what happens.
