Media Information: Laptop Hard Drive, Hard Drive Model: HTS541680AS File System: NTFS
Symptom: The laptop cannot be started. After the customer removes the hard disk and hangs it as a slave, it still cannot recognize it.
Data recovery process:
Mr. Liu said that the notebook will be turned off after work on Friday. On Monday, I found that it could not be started, and I heard a strange noise. The engineer asked the customer if they had fallen during the operation, told no, and never moved during the holiday.
After signing a confidentiality agreement with the customer, the data recovery engineer retrieves the hard disk back to the operation room of the Darth Data Recovery Center for preliminary detection. It is confirmed by the sound of the motor that the fault is a head stuck phenomenon.
After the engineer entered the Class 100 clean room for opening test, it was found that the head did not stop at the head start and stop area, but was stuck above the disk. With many years of skillful use of professional tools, the magnetic head was successfully returned to the starting and stopping area, and then the disk was sealed. Hanging on the PC3000 and using DE to disk-to-disk mirroring, all data was recovered.
Data recovery result: Data recovery succeeded
Summary of this case:
The faults in this case are very common and the success rate is very high, but there are a few points that are worth paying attention to. First of all, according to past experience, the phenomenon of head stuck, generally the head does not break, we all know that the original adaptability is the best, so we must cherish the first opportunity, so Greatly improving the success rate is also a manifestation of responsibility for customer data.
Secondly, in the process of dialing back the magnetic head, it is necessary to master the skills and try to avoid all the possibility of causing secondary damage to the magnetic head and the disc, especially for the hard disk that has been deformed by the magnetic head, if it is slightly lost, The platter is scratched, and the consequences are hard to imagine.
Finally, we should remind the customers and friends that when the data is lost, try to protect the scene, do not carry out redundant operations, and immediately contact the data recovery experts for rescue, so as to save the loss to the greatest extent.
