Hi FIO community, I am doing a data integrity checks to an SSD device (DUT - device under test) This is done with FIO using -verify=crc32c -verify_pattern=0x88888888 block size =4KB We get a failure, and there are *53248..expected and *53248.received. Could somebody explain the meta information in the beginning of the block data. We could locate the LBA (53248 = 0xd000) at location offset = 0x10, But a comprehensive explanation would help to identify the issue. What is the CRC32 field ? Does the CRC32 include the header information as well ? The Expected file is : 0000000: caac 0500 0010 0000 0000 0000 0000 0000 ................ 0000010: 00d0 0000 0000 0000 0000 0000 0000 0000 ................ 0000020: 0100 0d00 303c bb47 203f d2f2 8888 8888 ....0<.G ?...... 0000030: 8888 8888 8888 8888 8888 8888 8888 8888 ................ 0000040: 8888 8888 8888 8888 8888 8888 8888 8888 ................ .... 0000fe0: 8888 8888 8888 8888 8888 8888 8888 8888 ................ 0000ff0: 8888 8888 8888 8888 8888 8888 8888 8888 ................
