How does the hard disk recorder hard disk fault tolerance work?
Jan 17, 2019

  The fault tolerance of the hard disk is not only required for the car DVR , but also for ordinary DVRs . But from the current technical situation. The fault-tolerant and error-correcting capability of the hard disk is a problem that has been solved in the IT hardware industry or the software industry since the hard disk was available.

    For an embedded system, it is very difficult to achieve a perfect fault-tolerant error correction design! But the design of the embedded system is intended: the embedded system is originally designed to pursue better stability and execution speed, but there is a problem that cannot be ignored is that the portability is poor, which makes it impossible to design once it is too Big change. So its first design idea is very important. Embedded systems for fault tolerance correction of hard disks, the current effective way is read and write control capabilities.
