Verify says error when there is none.

Recommended Posts

This evening I burned three large (<1GB) AVI files to a DVD-R using CDBXP and during the verification stage it reported that one of the files could not be read from the disc it would have an error.

Rather than recycling it as a coaster, I decided to check the "offending" file myself and it ran perfectly.

What causes the verify to not work properly? It concerns me that if CDBXP was wrong when an error didn't occur, the reverse could happen in that it could say there is no error with the disc when there is one.

I hava the same problem.

After burning a file of 2350MB the verifivations tells me there were errors.

the big file on the disc has the wrong size. A verification with other programs

gives no errors. The burned file and the file on the harddisc have no differences.

I have a simular problem (3.0.116)

Verification always gives one file to be bad.

"Can't read ....."

Checking the file manualy gives no problem.

I have encountered this same bug with version 3.0.116. I burned

a bootable 8X DVD+R with a number of files including a 2.58GB

file. The Verification pass claimed that this big file was not

the same size on the disk as the original.

After it ejected the disk, I put it back in, and checked the file

size. It's exactly the same size (2,778,726,400 bytes) on the

DVD as on the hard disk, as shown by Explorer. I binary-compared

the file to the original using "comp" - it's exactly the same.

This is on a relatively fresh install of XP Home SP2, with all

critical Windows Updates applied.

If this bug can't be found and fixed, then the Verify function

should be removed from the program until it is. There's nothing

worse than a broken tool.

I've seen exactly the same problem, with a file of a similarly huge size. CDBurnerXP Pro 3.0.116 claimed there was a size mismatch, but the file on the DVD was in fact OK.

My initial suspicion would be that the verification code has a bug with file lengths greater than 2GB (2^31 bytes). Ideally, the code should handle unlimited lengths -- but, at the very least, storing the length in an unsigned variable would support files up to 4GB in size.
