With Windows (2000 or XP) is there a way to perform verify and rewrite
as part of copy operations?
What I am looking for is some option where for each e.g. 1MB written it
is check read and rewritten in case of error.
On command line I have tried copy with option /v. This seems to verify
after complete copy. Errors are reported but there are no retry of
writing the blocks found to be wrong.
If not part of Windows is there some utility with copy operation like
that I can use?
This is to debug an unreliable interface not a faulty drive.
TIA, Richard
Why don't you write your own copy program that
1) copies 1MB of data
2) flushes the I/O
3) reads the 1MB from the destination file and compares it
4) repeats until all data is copied?
Regards,
Alvin.
