clone a large hard disk to a smaller one with the help of free tools

created: 2022-05-11 from Bernhard

Free tools for cloning a hard disk cannot usually clone a large partition and thus a large hard disk onto a smaller one. Thanks to the command "Shrink Volume" in the disk management of Windows, the hard disk can be prepared for the cloning process and then cloned with the help of open source tools. Thus, for example, a Windows installation with all data can be moved to another disk.To speed up the PC with very little effort, a smaller SSD is usually used as the target. With the procedure describ... ... continue reading

Originally I listed various tools for a data recovery on this page. The tools were partly paid, partly freeware or open source. The functionality and the success of the products in recovering data was very similar: If physics allows it, most of the tools can do something. After some of the presented products are partly no longer developed and the focus on this page is primarily on free products, remains in sum an open source project with which it makes sense to start a data recovery attempt: The... ... continue reading

When cloning a large hard disk to a smaller one, I lost the recovery partition. So far not bad, Windows works without recovery partition, but in case of an error the partition helps to get the PC up and running again. To summarize, here's how it works with the recovery partition: As long as the partition is still there, it can be deactivated and written to a file. If the partition gets lost unexpectedly, it can be recovered from the Windows setup media. This post is also available as a video, se... ... continue reading
