I'm trying to copy a recording I made on Canon DC320 to my computer but I keep crashing with the message The parameter is invalid. I've done some troubleshooting using Process Monitor and xcopy and determined the following:

  • The crash happens at 311,033,856 bytes every time
  • xcopy retries 3 times automatically (I assume this is standard)
  • Buffer size is 65,536 bytes
  • Starting from 257,949,696, every read operation happens twice, the second time with Non-cached, Paging I/O, Synchronous Paging I/O set as I/O flags
  • Windows XP SP3
  • DVD-RW 1.4 GB (Sony)
  • Recorded on a Canon DC320 in high def
  • UDF file system
  • Tried with the same results on a Windows 7 computer

Here's the stack trace from the failing ReadFile command

Does it only crash with XCOPY? I mean, if you use MOVE, or a 'normal' copy and paste, does the same issue occur? Also, what does Event Viewer say? – Dave Jan 10 '13 at 11:27
You could try performing the copy using TeraCopy, it lists all the files it tries to copy along with any associated error messages that show up in the process. – Darth Continent Jan 10 '13 at 14:26
@DaveRook I only started using XCOPY in the first place because I got this error with a copy and paste (in Windows Explorer) – just.another.programmer Jan 10 '13 at 16:30

It appears your DVD cannot be read at the offending location. Is it scratched. Have you tried cleaning the surface or using another DVD drive to read it.

I checked the disk, it does not look like it has a scratch. I can play the video in the camcorder fine, so I don't think it's a scratch. – just.another.programmer Jan 10 '13 at 16:31
