Case:Computers are not recognized Solution:Change the same model line board and change ROM.After the power is charged, the motor does not turn, there is no sound, remove the line board, change the same model, the motor work, but still cannot be identified. It is found that the ROM of the board is different from the…
Case:The system cannot start, and the hard disk cannot be recognized. Solution:After the testing of the engineer, the hard disk has a total of five plates and ten heads. One of the magnetic heads is damaged. The engineer hand -handled the magnetic head by hand, using a special device to extract data, and the data…
Case:Suddenly the laptop was blue, and the hard disk was removed and put in the mobile hard disk. Solution:After the engineer passed the PC3000-UDMA detection, it was damaged by the magnetic head. The 1.8-inch disk was relatively rare, and the relative data recovery was difficult. After two hours of work at the 100-level dust workbench,…
Case:Move the hard disk, the desk fell to the ground, the customer immediately tried to put it on the computer to read, and there was a noise of the hard disk! Solution:After the engineer’s test, the hard disk magnetic head was damaged. The engineer replaced the magnetic head with the same type of hard disk…
Case:The hard disk is shut down normally, there is an abnormal noise in the boot here 1 Solution:After testing by engineers, the hard disk was abnormal, and it was determined to be a magnetic head damage. The magnetic head, full mirror image, and data recovery were successful.
Case:This server is an email server, and the power failure suddenly makes the server unable to work properly Solution:The preliminary test was that each group of RAID5 each group of RAID was damaged. The analysis of RAID data was lost. The authoritative server data recovery engineer successfully recovered through the ship’s virtual RAID information.
Case:There are abnormal sounds in the hard disk and do not recognize the disk Solution:Engineers used their own special tools to recover the opening data of the hard disk in the 100 -level dust -free environment.Causes of failure: hard disk overload work, magnetic head damage.
