DiskFresh Alternatives
DiskFresh is described as ' DiskFresh is a simple yet powerful tool that can refresh your hard disk signal without changing its data by reading and writing each sector and hence making your disk more reliable for storage' and is an app in the system & hardware category. There are three alternatives to DiskFresh for Windows, Linux and MS-DOS. The best alternative is HDD Regenerator. Other great apps like DiskFresh are DRevitalize and SpinRite.
The HDD Regenerator can repair damaged hard disks without affecting or changing existing data. As a result, previously unreadable and inaccessible information is restored.

The program is no longer updated since 2011, but it supports Windows 10 and can be still bought from the official website.

SpinRite is a computer software program for scanning magnetic data storage devices such as hard disks, recovering data from them and refreshing their surfaces.
