How SpinRite RECOVERS Unreadable Data
Disaster Recovery is perhaps SpinRite's strongest and most unique capability since SO MUCH MORE CAN BE DONE than any other disk utility has ever bothered to do. (Scandisk is probably the worst of all since it does NOTHING other than to simply discard any data that can't be read.)
SpinRite NEVER takes a drive's data for granted. It contains and deploys an extensive arsenal of data recovery techniques and technologies designed to pull a drive's data back from oblivion.
How does SpinRite recover lost data from a drive?
that troubled sector can never again be accessed!
The FIRST THING SpinRite does when it starts examining and working with a drive is to completely disable the drive's built-in automatic sector relocation. This way the drive can't whisk the sector away the first time it's not easily read, and SpinRite can study the sector to recover its data as much as necessary. (And as you might guess by now, no other utility is even aware of this problem.)
Erroneous Data Reading
It often happens that during this re-reading and data collecting phase, one perfect read will be received just by trying to read the sector many more times than other software ever bothers to. In this case, SpinRite reports perfect data recovery then re-enables the drive's auto-relocation so that the defective sector is now released and replaced with a perfect (but empty) spare. The region is then tested extensively and the data is perfectly written back onto the drive.
Accept Partial Data
SpinRite will log the name of the file whose sector was not completely recovered and replace the file's completely unreadable sector (which any other software would have simply discarded) with this "mostly correct" now-readable sector so that all but a few data bits of the file can still be read and used.
file due to one of its sectors being completely unreadable.
The result of all of the above has earned SpinRite the reputation for being a "miracle worker" and being "pure magic." But as you can see, while the results for the user might indeed be magic,
honest work, and comes through
when it matters most to its owner.
Everything you've read above is completely unique to SpinRite. NO OTHER UTILITY does any of the things you've read above. Not one. Does it make ANY SENSE to be using a computer without a copy of SpinRite lying around?
As Richard O'Reilly wrote in his Los Angeles Times review of SpinRite:
"After testing SpinRite, I am convinced that it is a must-have product for most users of IBM or compatible PC's with hard disks. SpinRite may well be the best investment you can make in the integrity of your system."
Now you know why he said that.
