Post subject:  explorer.exe and cyclic redundancy checks
I am attempting to copy files from a failing windows ntfs formatted drive. It's plugged into external enclosure and connected to my laptop running windows xp sp3. When explorer.exe reaches a file that it cannot access/read it gives an error message: Data error (cyclic redundancy check) and stops the copy process without trying the rest of the files I had selected to copy.

Out of 560 picture files I had to drag and drop each one manually to determine these files would give the crc error:

121.JPG
164.JPG
180.JPG
226.JPG
245.JPG
298.JPG
299.JPG
335.JPG
419.JPG
525.JPG

Is there a way to make windows explorer continue on to the next file automatically so I could just drag and drop all 560 files without the copy process crapping out part way? Or perhaps there's a better way to just do a quick file copy of what's accessible by copying the parent directory without it crapping out part way through? A registry option perhaps? Any ideas?

the problem you got there is that where the files are on the hard drive itself

they are located on the bad sector of the hard drive.

that why your getting crc error as they are all bad sectors


dont tell me you own a seagate drive ?????????????

once this happen bye bye data forever
as i tried everything going to recovery the data when my drive went down

That's just how explorer works. Use something else like xxcopy. In your case since it is due to bad sectors on the drive you should not be running it in windows anyway, but imaging it to a good drive instead.

I forget which brand the drive was but yes, normally I'd create a disk image to a good drive if I was back at my home. I was doing this On-site for a friend who really only needed a few directories and individual files backed up before sending the laptop back under warranty since windows wasn't bootable on her notebook.

I discovered that

Code:
copy *.* source_dir destination_dir


via CLI would skip the files located on the bad sectors that failed the CRC (with a file skipped warning) and continue on to the next files without halting the entire copy process. I was able to get her the 1 critical file she wanted in addition to most of the pictures & music she wanted since her laptop wasn't bootable. Mission accomplished.
