Case:There are abnormal sounds in the hard disk, and there is no way to identify the hard disk, but it has not fallen and it is naturally damaged. Solution:Apple laptop hard disk, Seagate 500GB has obvious abnormal noise. Customer Mr. Liu said that he had not fallen, and may be moved when used. It can…
Case:At first, I could open the partition and tried to copy the data many times, but I couldn’t copy it. Now I can’t recognize the partition. Solution:Customers have tried to copy data many times, which cannot be copied normally due to the bad ducts, and the bad sectors have seriously spread, which increases the difficulty…
Case:The server was first on the yellow light on the 3rd plate. It replaced the No. 3 light disk with a spare disk. It was still not possible. It should be that the array has been dropped. Solution:Our company immediately sent the engineer to check the inspection, confirming that the array had fallen, and the…
Case:The hard disk cannot be recognized, and the hard disk has the sound of knocking. Solution:The detection is damaged by the head, and the magnetic head needs to be replaced in the dust room of our company, and the data is treated with the image of the fault disk.
Case:Accidentally the host fell to the ground, and then the hard disk could not be identified and there were abnormal noise. Solution:The magnetic head has been damaged, and there is a sound of hitting the disk.
Case:There are two hard disks with problems, and array information is lost. Solution:After testing, the hard disk No. 2 3 4 has a different degree of physical bad ducts. The No. 4 disk is more serious. Mirroring on the 23rd disk is processed, and then the No. 4 disk is lacked for virtual reorganization. The…
Case:The hard disk cannot be recognized, and 800G video files are restored. Solution:The detection is damaged by 0 magnetic tract, and there are a large amount of physical bad ducts. To do the entire mirror processing, the data recovery is successful.
Case:The boot was not reflected, and the hard disk could not be recognized. Solution:After the engineer was tested as a circuit board, the circuit board was replaced and the chip information was replaced. The data recovery rate was 100%
Case:The laptop suddenly crashed, and it could not be used again, and there was a sound of the hard disk. Solution:The aging of the magnetic head has been damaged. The magnetic head is replaced and the sector mirror processing is treated with the fault disk. The data is 100%recovered.
Case:The hard disk is dropped, and the heat disk is not launched, causing the array to lose. Solution:After the engineer’s test, the hard disk did not have a hardware failure. It could directly logically recover. The virtual combination was used to recover the RAID recovery software, and then the engineer analyzed the data positioning and…
