What is CRC32?

The CRC32:CRC itself is the meaning of "redundant check Code", and CRC32 indicates that a checksum value of 32bit (8 hexadecimal digits) is generated. Since each bit (bit) of the source data block is involved in the calculation when the CRC32 produces a checksum, a different CRC32 value is obtained even if only one of the data blocks has changed.

CRC is a data error checking technique that ensures that the data originally written to the image file is consistent with the data used in the image file.
CRC32 indicates that the error checking information is saved using 32 bits, and when the image file is created, the details of the CRC32 are embedded in the file to ensure that it is detected as corrupted when the file is restored to disk.

Display CRC32 error, image file may be corrupted

It is important to note that it is best not to defragment the partition that the ghost image file holds, otherwise it is easy to corrupt the ghost image file.
