To protect the security of files/data, I have always found it preferable to hide and/or set an access password for a partition rather than to encrypt the partition or an entire hard disk. The reasons are: 1) The performance and efficiency of reading/writing encrypted files are extremely low; 2) As far as I know, although an encrypted file is hard to crack, it is the most likely to happen and the most deadly for users to forget their encryption key - there is no solution at all; 3) In fact, even if you just hide one partition without password protection, few people would expect you to protect your private data in this way.

When phasing out the use of hard disk and other devices storing digital data, for ordinary users, the private data inside should be erased effectively in order to avoid the abuse or leakage of privacy made by people with ulterior motives; for enterprises and institutions, the data is often very important, sensitive and confidential, so that they must be destroyed strictly. To do this, we have to turn to some third party professional data sanitizing tools, because deleting the data itself and formatting the entire disk are all futile.
