it dosen't sound to me that there is anything wrong with your disk. it

i liked the idea of this possibly being a problem with the file name. can
you rename the current file and then try to copy it?

Okay, I tried that. It didn't work.

or just delete it and start over with a new copy from the backup that you
said that you had.

I tried copying from the backup. It copies from the disc okay. I then
made a copy of that file with no problem. Thanks for the suggestion.
It's weird. Nothing seems to be wrong with the hard disk, yet it can't
be copied.

Another thing I noticed. I copied the backup to a partition that
doesn't have the bad file on it. When I copied that file to another
file Windows estimated the copying time at around a minute and it took
maybe 1 1/2 or so. When I tried the same thing with the bad file
Windows estimated the copying time at around 4 minutes. That seems
strange.

Whatever you do, if you want to recover your AVI file, DON'T run CHKDSK

replace them with empty spares, corrupting your AVI file.

:-) Thanks. I've also heard bad things about chkdsk over the years. It
seems to
be the Windows 2000 replacement for Scandsk from what I've read. I'm not
trying
to recover the file. I have another copy. I just want to get the computer
working properly. So it looks like I'll be getting another hard disk.

I'm surprised though that with Windows 2000 Error checking software
( http://support.microsoft.com/kb/156571/ ) and Seatools from Seagate did
not
find anything wrong with the disk. If it's got bad sectors, I wonder why
these
programs did not find anything wrong.

Thanks.

Well, depending the manufacturer of the drive, there may be a free

utility to do the same reapir that SpinRite does for a lot less money.
Hitachi/IBM, Seagate, Western Digital and others are able to allocate
replacement sectors from a group of spares. All of them, including
SpinRite,
make best efforts to copy the data from a defective sector to a
replacement, and
"best efforts" means that the "copied" data may be off by a bit or two or
more.
The only advantage of SpinRite is that its best efforts try a little
harder to
reconstitute the data from a bad track correctly... Ben Myers

I am trying to copy a file on the hard disk to another folder on the

one file.
I'm using Windows 2000 with sp4. I've tried several times and get the
same error
each time. It's a 350MB file and the error occurs after copying around
3/4 of
the file. Other files this size and bigger can be copied with no
problem.

I think I had the same error message when copying files from a jump
drive to the
hard disk. After trying a second time I was able to copy the files.

Chkdsk doesn't find any errors on the hard disk. It's a 40GB Maxtor.
The hard
disk is connected to an SIIG Ultra ATA/100 controller (purchased from
Dell). The
drivers for the card are installed.

Does anyone know what could be the cause of this problem and how I can
fix it?

Thanks.

If the error occurs when using the standard windows explorer copy
facility and occurs 3/4 through your large file, then you are having a
disk problem. That particular block cannot be read correctly off the
disk.

You have to decide how important your unreadable AVI file is. If it is
worth > $89 then you should purchase a product such as SpinRite
http://www.grc.com/sr/spinrite.htm which will do its level best to fix
the errors on your drive. I have no connection with GRC, other than as a
very satisfied customer.

After recovering your file(s) you should replace the failing disk as
soon as possible.
