Lenovo win7 system computer detects the number of times the OB attempts to recalibrate the hard disk. "Warning information how to solve

win7 system often needs to detect the hard disk, check the transmission rate, health status, and temperature conditions, etc. Lenovo win7 system computer detects the hard disk “OB attempts to recalibrate the number of times” warning message, why is there such a reason? The following small series introduces the win7 system computer to detect the number of times the hard disk appears OB attempts to recalibrate ” three reasons and solutions for warning information, sense Interested users can learn together.

Interpretation: Calibration retry count refers to the number of times the head fails to read and re-reads, and not all manufacturers' hard drives have this parameter.

Fault reason:

1. If the head is not returned to the safe area due to a sudden power failure during use, the disk chip will record once “ the number of attempts to recalibrate>;

2, the hard disk will be tested and tested before leaving the factory, including abnormal power-off operations, that is, counting;

3, In addition, some Seagate and other hard disk manufacturers if this phenomenon occurs, due to the shock arm reset technology, this phenomenon is mostly false positives, do not worry.

Solution:

Please observe “ Try to recalibrate the number of counts, if the value is stable, do not worry, this is not a hard disk failure; if this parameter continues to grow, there may be a risk of failure, please backup important data on the hard disk in advance. Br>

The above is the Lenovo win7 system computer detects the number of times the OB tries to recalibrate the hard disk & rdquo; the solution of the warning information, I hope to help everyone.
