Re: recover currupted files

Rich,

Either you didn't bother reading the posts, or you are simply arrogant.
I guess you spent too much on those other companies recovering a file.
I only spent $40 and got all my files back from my drive.
And, yes... it was formatted and re-partitioned.
(Exactly what the vendor stated their software could do.)

As I stated in my prior post, the corrupted file is useless.
My point was the original data may be recovered from a different version of
the same file that is in an "erased" state.

I didn't state all files could be recovered. I stated I had good success.
(In my case, I recovered ALL my pictures and documents.)
I thought I was clear stating that to recover from the "corrupt" file:
1. The files had to be modified or re-saved... meaning written to the disk
more than once, or
2. The area written to originally was not written over.

This allows "restoring" the "other" version of the same file.

Most drives when formatted do not use the full format option leaving the
data area untouched.
Re-partitioning does not wipe the drive.
With these two simple tidbits, most files can be recovered from formatted or
re-partitioned drives by a program that looks at the drive in raw format,
finds all the allocation tables and rebuilds them. Comparing file storage
indexes creates the percentage of success of any one file being recovered
and minimizes the effort of sorting through a lot of garbage files.

The more expensive restoration:
While wiping a file if extremely effective, wiping a file almost never
touches the File Allocation Table. So, even though the data is "gone," the
exact location of a file can still be determined, and yes, with the right
software, it can be recovered. (Unless you use a multiple wipe with random
data. Seven times recommended.)

The impossible:
If the surface of the hard drive is corrupt, you cannot recover the file.
Degauss the hard drive.
If there is only one original of the file and it is recovered corrupt, then
it typically cannot be repaired.
