We know the reasons for data loss from external hard drives

There are a multitude of possible reasons, when an external hard drive isn’t recognized any more. In the majority of cases, hard drives are physically defective. Damaged write-read heads, a stuck platter spindle, damages on the magnetic surfaces or faulty firmware are the most common errors, when there is no more access to the data.

General information about external hard drives

With external hard drives you have to distinguish between the different types (common are 2,5 inch and 3,5 inch) as well as different interfaces, which has an impact on the data rescue of a physically damaged hard drive. Increasingly, the USB interface of 2,5 inch hard drive is on the board (PCB). With external 3,5 hard drives, so-called internal HDDs with internal SATA interface are used, the interface (USB, Thunderbolt, eSATA, Firewire, LAN) is on the external casing.

Very often a drop or impact lead to mechanical damages of an external hard drive. These hard drives often suffer a headcrash (impact of the write-read heads onto the magnetic surfaces), noticeable through clacking / clicking / ticking / beeping / scratchy noises from within the hard disk. Furthermore a wrong power supply can lead to over-voltage and damages of the hard disk PCB. The hard drive won’t spin any more. External influences, such as moisture (water, coffee, liquids) or heat / high temperature (e.g. solar radiation) can affect hard drives as well as defect or deformed connection interfaces (USB, Firewire, Thunderbolt, eSata). Apart from physical damages, hard drives can also be affected by logical damages within the file system.
