cycle reducdancy?? |
|
|
I am a photographer and have many files in my albums. In one folder there is
a file that I can get no info on and it freezes my computer if I try to ope,
delete, or even copy to a CD. The error message says, cannot delete-data
error (cycle reducdancy check). Does any one know what a cycle reducdancy
check is, or any way to delete this file? Many thanks in advance.

Hello Photolady,
Try re-taking ownership of the file or folder. If that
don't work ... try chkdsk /f

The CRC error you are getting is because you might of done a defrag when that
file was still open, thus it moved the file into 2 seperate spots and windows
cannot determin the spot it is in. Try backing up the rest of your data and
boot the computer into safe mode and try getting at the file that way.. that
should work for you |

Hi, Photolady.
I'm no computer scientist, so I don't understand the full details, but maybe
I can help a little. I've been using personal computers since the 1970's
when they were called "microcomputers", among other things. I first saw CRC
errors when we moved up to floppy diskettes. :>(
The Cyclic Redundancy Check is a sort of "hash code" system. Accountants
used to use hash codes, and I suspect people in other fields use them, too,
or something like them. If we wanted to be sure that we had copied all the
numbers on a page correctly (before the days of copy machines), we would add
every number we could find on the original document (including phone
numbers, page numbers - ANY numbers) to arrive at a total. Then we added
all the numbers on the new copy. If we got the same sum, we could be pretty
sure we had copied correctly. But if we got different numbers, then we were
SURE we had goofed somewhere.
The CRC does something like this behind the scenes when a file is copied.
All the numbers are subject to some mathematical algorithm to arrive at a
single "checksum", which is recorded along with the file. After the copy,
the same algorithm is applied to the numbers in the copy. If they don't
jibe, the CRC error pops up. It doesn't (can't) tell us how to fix the
problem, but it lets us know that there is a problem so we can look for a
solution.
Now, as Paul Harvey sometimes says, "Don't ask me for details. I've already
told you more than I know!"
If you have an earlier copy of that same file, see if you can refresh your
"bad" copy from there.
If you need more information, Google turns up LOTS of hits on "crc".

LOL!
Now even I can understand CRC! What a lovely explanation!

Thanks, Bjorn!
Reminds me that I never did get around to thanking you for the Swedish
"Welcome" you sent me several months ago. Thank you!

I think you did thank me, at least I have a thank you email from a Richard |
Charles somewhere... ;)
Hope the event went well.
Anyway, we might be better off using email to continue this conversation...
;)
