Fault type: partition failure after restoring the system

Typical characteristics:

A, the original multiple partitions become the current one.

B. the number or size of the original partition is different from that of the current partition, and the original partition is lost.

Degree of damage: level 3

Recovery process:

I. testing

1. Check the size and number of failed disk partitions through disk management.

two。 Check the integrity of the current partition structure.

II. Recovery

1. Ask the customer about the original partition size and number of partitions.

two。 Carry on the comprehensive analysis according to the customer feedback information, classify and summarize all the partition features.

3. Check the file structure of each partition according to the mark characteristics, and find out the location and size of each partition.

4. Restore the structural state of each partition, and if the original partition is damaged due to the current system writing, it will be repaired according to the solution of the corresponding file system damage until the data required by the user is migrated.

III. Acceptance

1. Do attribute statistics on the migrated data to ensure that all the data required by users have been migrated successfully in terms of the number and capacity of files.

two。 Verify the integrity of all migrated data to ensure that the files are correct in terms of directory structure and underlying logic.

3. Pertinently check the key data files specified by the user to ensure the successful recovery of the user's critical data.

Reliability analysis (time estimate):

1. If the fault disk becomes a large partition after restoring the system, the other partitions except disk C can be completely restored for 1-2 hours.

two。 If the number of partitions after restoring the system is different from that before, the other partitions except disk C can be completely restored for 1-2 hours.

3. If the system is restored to a partition, the data recovered from the partition restored by the system will be partially lost, and the time will be between 1-3 working days.

Tip:

1. When the system is restored, it is best to back up the data of the original disk.

two。 Correctly select the partition to restore when running the GHOST restore software

3. Be careful to use one button to restore the software.

4. In case of problems, professionals should be consulted in time to prevent further damage to the faulty disk.
