cyclic check eror

[Manic]

I am trying to copy some data from a backup cd and no matter how I try to do this I always get a cyclic check error.

Is there any way or util that I can uses to get round this check??

it is only a few of the data files that I am losing which I don't mind but it is very time consuming to do them in small batches to avoid them. There are about 3000 files.

any help would be greatly appriciated.

Hello Manic,

Run command.com and try using the dos-command xcopy.
Here´s the syntax:

xcopy source [target] [/switches]

Some useful switches (especially for your use) are:

/E copies all subdirectories (empty or not empty)
/C don't stop at errors (think this is what you want...)
/? show help for syntax (use "xcopy /? |more" for 1 page)
..btw. if you use Windows 2000 or XP, you can scroll
in the windowed DOS-Box..

example:
C:\>xcopy D:\*.txt C:\mytxts\ /C
would copy all *.txt-files from drive D: to harddrive-dir
mytxts.

I think your CD is perhaps a bit scratched or not burned
properly... Back it up soon.

Hope this helps,
pharcyder

Sounds like you either have a bad cd player or a CD that is partially corrupted.
My question is, how was the CD written and was the session closed? Is there scratches on it? Is the coating flaking off (holes)?

Sorry, but have you tried using different cd-drives ?

Some cd-drives are not good reading burned cds, especially
when they`re scratched.

Try using a cd-drive with low speed. Or try burning the CD
with single speed, best programm is CLONE-CD with NO
error-correction (try with and without...)
So the errors are copied too but you can read the new
CD much better, just sort out the damaged files then.

Oh, try making a disk-image, don't burn "on the fly", it
could take some time for Clone-CD to recognise the errors.

Greetings,
Jens
