I’ve outlined a number of solutions here however, I won’t get into them just yet.
Once that’s established, it’s left to you to make the necessary steps to fix the problem. With that said, in most cases, if the data error cyclic redundancy check is due to the tape drive, then you’ll receive a write error, which should abort transmission. This means you must consider both possibilities, as it could be the software or the hardware. However, it’s also possible for the CRC to occur in the backup software. Most tape drives that you’ll purchase today, do support CRC, which means the error could have occurred in the drive itself. At which point, it’s left to you to determine where exactly the data error cyclic redundancy check is occurring.
When this occurs, the drivers of the device (tape drive), will report an event Id 7. How exactly does this data error Cyclic Redundancy Check work, well let’s say for example you have a backup application that is transmitting data to another device, such as a tape drive, and during the transmission a Data Error Cyclic Redundancy Check is issued. The CRC n-bits that are applied to each data block, work to ensure that the data that is sent, is the same data received, on the other end. The reasons why that is so important is because burst errors are the most common, as they occur in a number of difficult communication channels, such as optical and magnetic storage components. The main advantage of this error-correcting code is the fact that it’s much simpler to implement than other methods, and is also well suited for the detection of a number of different error types, particularly burst errors. This particular cyclic code was conceived by Wesley Peterson in 1961. In this post I’ll be talking about the data error cyclic redundancy check, what is it, why it was created, and what to do when you encounter one of these errors.Ĭyclic Redundancy Check or CRC is basically a method developed to ensure that data does not become corrupted during transmission.
