Hard disks

All types of interface:ParallelAta (PATA)/IDE, SerialATA (SATA), USB, Serial attached SCSI (SAS);

Simple and individual drives, or RAID drives (0, 1, 5, 6, 10);
All brands and designs (Seagate, WesternDigital,Maxtor, Hitachi, Fujitsu, Toshiba, HP, IBM, etc.);
Internal or externaldrives fromservers,desktops, laptops andother devices;
All sizes ofharddrives: 3.5 ", 2.5", 1.8 ";
All types of mechanical or electrical failures;

Typesof possible malfunctions/damage:
(So you can detect what kind of malfunction/damage you are dealing with)

Logic – these are some of the most common and easiest problems. In such case, hard drive is not physically damaged, but the data stored on it is not readable or recognizable. Damage can range from simple logic malfunction, incorrect entry of files in the “schedule/location” table, to file damage.
Your data may be lost due to virus activity, formatting, partitioning and repartitioning of the disk, random erasing errors, partition reading errors, damaged sectors (BAD sectors) and many other errors.

Electrical – damage of electronic components on the printed circuit board (PCB) is very common after electric shock or short circuit, and after that BIOS doesn’t recognize the HDD. These defects can occur on any type of hard disk, regardless of manufacturer, model, size or quality.
In those situations, recovery of your data is 100% guaranteed (with the necessary replacement of electronic components), because the data itself is not damaged.

Mechanical – it’s the hardest and most complex type of damage with the highest probability of failure in data recovery. This malfunction can lead to partial or permanent loss of data stored on disk. This may be caused by errors while reading or writing data on the hard disk magnetic plates, by mechanical shock, engine failure, etc.
In this case, the most common damages occur on reading/writing section of hard disc. The error occurs when this section comes into contact with the magnetic plates on hard disc (physically touchesthe magnetic plate, where data is being written/stored). Mechanical failure can be caused by external forces (fall, shock, earthquake), static electricity, voltage fluctuations, short circuits, but they can also occur on the magnetic heads, as well as on the electronic part of the head.
Mechanical failures can be detected by hard disc “croaking” or, in other words, harsh sound that can be constantly or occasionally heard from the hard disc. If you notice this kind of sound, we recommend you to shut down your computer immediately, because this will increase chances for successful data recovery.

The most common causes of data loss:

  • Errors in the electrical network/power supply, voltage fluctuations and voltage peaks;
  • Rewriting and/or deleting;
  • Mechanical malfunction/damage;
  • Accidents(e.g., fire, flood, etc.);
  • Computer viruses/malware
  • Human error;


  • Unusual sound and vibration;
  • Operating system errors;
  • Data reading/writing takes too long (or even “forever”);
  • Your HDD is "invisible" on computer, unrecognized by BIOS and the operating system;
