Laptop hard drive repair method How to repair laptop hard drive: The author has a Fujitsu laptop hard drive, which has been working unstable recently. In order to find the cause, I first backed up the important data on the hard disk, and then used maintenance software to completely clear it to eliminate logical bad sectors. Then the disk was tested and found to have some defects and "unstable" sectors. In this case, the author decided to use the Fujitsu 2.5-inch notebook hard drive repair and data recovery software developed by Domestic Efficiency Source Technology in 2004 to repair this hard drive.

Laptop hard drive repair step 1: Since the repair involves firmware operations, the risk is high, so the firmware of the failed disk must be backed up before repair, just in case. The specific method is: use the Read fw (read out all firmware programs of the current hard disk) and Readrom (read the BIOS content in the current hard disk circuit board) provided by the efficiency source software to perform backup operations.

Laptop hard drive repair step 2: Execute the Rebuild function in the software. The main function of this step is to self-correct some errors in the firmware. At the same time, clear the G-list and reset the S.M.A.R.T. table.

Note: Hard drives generally have two defect lists: initial defect list (P-list) and growth defect list (G-list). The former is filled in by the manufacturer during internal factory inspection (SelfScan), and the latter is used to record defects found during the use of the hard drive.

Laptop hard drive repair step 3: Execute the Scan function in the software to scan the hard drive for physical bad sectors, and set the scan threshold to 5000 to scan the bad sectors and Unstable sectors are added to the P-list.

Note: Since the original G-list is cleared when the Rebuild function is executed, the Scan function must be used to add the original G-list and unknown defects in the failed disk to the P-list. And because there are unstable sectors, the threshold when scanning sectors must be modified (the default value is 60000); if you want to add unstable sectors to the P-list, you can choose to fill in 5000 (the lowest value).

Laptop hard drive repair step 4 : Execute the Rebuild function in the software again for the purpose of performing routine testing before the hard drive becomes low format.

Laptop hard drive repair step 5 : Execute the Format (here means low format) function of the software to make the operation of adding P-list take effect.

Note: For Fujitsu hard drives, after adding bad sectors to the P-list, you mustIf the format is too low, the adding operation can really take effect, otherwise the bad sectors will still exist when scanning the hard disk.

Laptop hard drive repair step 6: Perform the Fdisk (partition) and Format (format the hard drive in DOS) operations under DOS, and finally install the operating system, and the hard drive finally returns to normal operation. !

In addition to the maintenance software of Efficiency Source, PC-3000 PCI also provides good maintenance support for Fujitsu notebook hard drives. Friends, if your hard drive encounters a similar situation, you might as well try the method provided in this article.
