The workhouse of the computer is the hard drive. Therefore, it is important to know the functions and working of the hp hard drive. The files that we save are magnetically recorded onto the platter which is placed inside the hp hard drive. The unit of data held by the platter is tracks/inch. The track is equal to 1 concentric ring around the disk. The track is further divided into sectors, and the sector is equal to approx. 512 bytes. The saved data on the disk is referred accordingly to its sector and track.

While searching a file, the hard drive more often makes a whirring sound. This whirring sound is created as the platter spins and the read heads move back and forth to access the data. The process can be made faster by de-fragmenting the hp hard drive periodically. The de-fragmenting of hp hard drive can be done with the help of Windows Disk Defragmenter, which reorganizes the scattered data on the hard drive. Once, the de-fragmentation is done, the files on the hp hard drive run faster and more efficiently. The de-fragmentation process shifts the files to the beginning that are used most often.

The Windows Disk Cleanup application sorts through the hp hard drive and deletes unused and temporary files. In this way space can be made available on the hp hard drive which speeds up the operations.

The files in normal daily routine are regularly read from and written to the hp hard drive, often in small chunks. The ScanDisk scans the hp hard drive to detect if there are any errors on the hard drive. If it finds any errors on the hp hard drive, the ScanDisk marks the cluster of sectors containing the error as unusable. In this way no data can be written to or read from that portion of the disk.

The hp hard drive can run smoothly well past the time it has become obsolete with the help of simple maintenance.
