Detecting and repairing method for respond loss of Seagate hard disk caused by data area sequential access

The invention discloses a detecting and repairing method for respond loss of a Seagate hard disk caused by data area sequential access, and belongs to the field of data restoration. The detecting and repairing method comprises the following steps: S1, inspecting a state register, and if DRD, DWF, DSC and ERR are 1 and BSY bit is 0, verifying returned data; if the whole section is verified to be a string of meaningless null data, showing that the problem is the respond loss of the Seagate hard disk caused by data area sequential access; S2, sending a reset instruction to the hard disc. The detecting and repairing method provided by the invention has the beneficial effects that through the adoption of the method, whether the hard disc is in the state that the Seagate hard disk loses respond due to data area sequential access can be quickly detected, and corresponding repair can be performed without tedious manual handling.
