Secondly, it should be said that you can download data recovery software such as Fina date online. It should be noted that this kind of software needs another hard disk to store gray data drops when it runs. {Note: It is another hard disk, not another one.

Hard disk partition}.

Also, if the hard disk is of low standard, you can't recover the data. Most of the recoverable data can be recovered by data, but not all, so check the paper when you bring it back. If the paper is not too big, you'd better rewrite it. If it is an audio-visual media file, it is best not to use data recovery. ......

Finally, I want to say that we should form a good habit of backing up data on time in the future.
