UDMA (Ultra DMA) stands for Ultra Direct Memory Access. It is a hard drive technology that allows hard drives to communicate directly with memory without relying on the CPU. CRC stands for Cyclic Memory Check, which is a checksum that can detect if data is corrupted.

When you combine the two, the Ultra DMA CRC error count indicates problems with the transfer of data between the host and the disk.

It is a one-time error that can be caused by anything. So, you don’t need to care about it unless it keeps going up.
