Case:
The customer describes the hard disk to recognize it under the BIOS, but it cannot find the partition, and it is 0 bytes to see the hard disk hanging on other machines.
Solution:
Enter the PC3000, there is no problem with the detection. When you enter DE, you can see the four partitions but one cannot be opened. So I opened it with Winhex and saw that the hard disk was filled with some garbleds from 0 to 62, but the No. 63 Slocked area No. 63The DBR is normal, so a normal disk is directly copied. The computing of the main partition and the expansion partition are rewritten to the repair partition table. After that, the four partitions can be seen normally, and the data is 100%recovered.
