Author: mountain walker After Fedora7 is installed, I configure my machine while surfing the Internet and record the process so that the system can be restored quickly after reinstallation. In fact, this is not the case, after the system is ready, you can back up the system. For example, you can back up the/etc,/var,/home, And/root directo

hard disk enters the protection mode. In protection mode, you may not be able to see parameters such as the hard disk model and capacity, or you may not be able to access any read/write operations. Recently, some series of hard disks have similar common faults Due to this reason. For example, the self-check sound of the Fuji MPG series is normal but the disk is not recognized. The maxtor series cannot recognize the correct model and stop switching af

Block Addressing (LBA) that allows a hard drive's sectors to appear to the OS as one long sequence of data with a concurrent address for each sector. typically, when referring to an Eide drive, the "e" is assumed and not mentioned. The current ide drive standard is the ATA 100 interface that supports data rates up to 100 Mbps. in August 2001, maxtor introduced its ultra ata 133 interface, branded fast drives. this interface is capable of transferri
