BurnInYrdy B5.1 Pro Unable to get disk Volume extent info

[RaySiah]

Hi, I'm running burn in test for one of my removable drive (compact flash card) and I'm getting Unable to get disk volume extent information. What does that mean? Is my card defective?

I am unable to find any description regarding this error at Help files: Common Test Error Messages. Please advise.

It means the flash drive device driver does not supply the disk geometry information needed for the disk test to run the Butterfly seek test.

It does not mean that the the flash card is defective.

You should select a data pattern that does not include the Butterfly seek test, or ignore the error for flash drives.

Best regards,
