the backup. When files are stored, they are written to contiguous blocks without fragmentation. This is a big job. 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.

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
