Case:
After an accident occurred on the evening of October 8, 2011, the public security system called out the record of Dahua surveillance installed at the mall installed at the time, but when the camera was played to a certain time, it automatically stopped and lost time.There are 4-5 hours.Later, the public security system found a local data recovery company. This company detected a large number of bad disks. After using DE mirror image, the official hard disk downloader of Dahua could not recognize the key time points.
Solution:
Generally speaking, for common monitoring or being formatted by partitions on the computer, recovery is a method that uses a full -scale scanning Dahua file format, but there are several file formats in Dahua.In each frame of embedded records, the conventional method is not distinguished from the channel information. At present, the Dahua’s views in this format can only distinguish the channels written by the data recovery center by themselves.The recovery software written by the data recovery center can easily find the data of the critical time point and restore it to play normally.Engineers suggested that hard disk data recovery needs to find professional engineers to recover.
