) directly affects the normal use of the hard disk. Today's machines support the "IDE Auto Detect" feature, which automatically detects the type of hard disk. When the hard disk type is wrong, sometimes you simply cannot start the system. It is recommended that you check the BIOS settings to see if the

It may be unnecessary for program partitions that do not change frequently like/usr, but it can create a miracle in the/home partition of a multi-user system. It takes the same time as the disk fragmentation of the Windows NT Server.

What are the laptop hard drive interfaces?
Notebook hard disk has two kinds, one kind of ATA interface, commonly known as IDE hard disk, another kind is now more commonly used SATA interface, serial port hard disk, but a few year
What to do if the BIOS does not recognize the hard drive:
In the first case, the most likely data cable is not plugged in or there is a problem with the data cable. Or the power supply problem, the hard drive is supplied directly from the power supply interface to obtain power.

Boot into the motherboard BIOS, the SATA in BIOS is set to compatibility (compatible mode) or IDE mode. HP Notebook BIOS entry is F10, as for setting up your BIOS version, set the location is not the same, but the setting method is to set SATA to compatibility mode or ID mode. You can also try

A hard disk partition consists of a primary partition and an extended partition, with a maximum of four partitions. If all the IDE Hard Disks are primary partitions and extended partitions, they are hda1, hda2, hda3, and hda4 respectively. If you want to have more partitions, you can perform logical division in the Scalable partitions. The initial partition start
