Hi,
Would you explain your situation with more details?
Did you use the older hard drive in Windows PC? How do you connect it to the current PC? as an internal drive, or an external drive via USB, etc. What can you see the drive in BIOS, Device Manager, and Disk Management?
Anyway, to enable us to help you better, you need to provide as many details as you can.
Regards,
