Hard disk drive (HDD) data recovery
Data recovery from the hard disk drive begins with the diagnosis of device. If it is determined that there is a problem in the mechanics or electronics, is it necessary to make the temporary repair of a hard disk, in order to access to data.
Hard drives are devices that are not meant to be repaired, but is necessary to replace defective components. When there is no more mechanical or electronic barriers, it is possible to continue data recovery process.
Data recovery from the hard disk is further done by cloning the content of the drive, sector by sector.
Hardware malfunctions on hard drives can be divided in categories:
- Logical problems – lost partition, deletion of data, damage caused by viruses, reinstallation of the operating system, damaged database
- Electronics failure – electric shocks, overheating
- Head crash – non-functional element for reading /writing the data, identified by loud rhythmic clicking, which can be heard from the inside of the casing
- Motor failure – jammed motor, recognized by weak buzzing sound coming from the hard drive
- Firmware issue – can be recognized if the data on the hard drive is inaccessible and the hard drive makes no specific sounds
- Platter damage (Bad sectors) – The problem with bad sectors can be recognized by the slow work of computer, lack of access to some data and directories, as well as the automatic turning on of CHECK DISK.
