Hi hank,
We are using Vdbench503 to verify our card function.
When we run file system test with data verification (-v), vdbench reports data mismatch.
1) It always reports LBA field with 256KB offset.
2) Error report Data Validation key always is 01.
from this , it seems that the first write data is not correct during creating file system.
I post parmfile.html & errorlog.html here.
