I have a Linux Mint hard drive, from a dead computer, in an enclosure that I want to clone to another external hard drive.
Do you want to simply recover your home directory or would you like to copy the entire drive to another drive? Assuming that the drive in the enclosure isn't damaged I believe you could simply transfer it into a new enclosure. but otherwise you would need a way to connect both drives to a machine and copy the contents from one drive to the other. I'm not 100% but I believe dd can get the job done, but don't quote me on that.
