What failures can Data Compass help to solve?

1.Logical Malfunctions
        Partition Loss
        File loss or destruction
        Virus attack
        Accidental formation
        Accidental deletion or clone
2. Physical malfunctions
Data recovery from a hardware drive with physical defects within the firmware Service Area, unrecoverable using
conventional processes. (Note: IBM/Hitachi drives are currently supported and other brands will come with this
feature in the near future)
        Data Recovery from drives with severe defects in the firmware service area using hot swap by Data Compass
        Based on that the data area can be accessed by DC and DC can recover data from "clicking" drives caused
by poor performance of the Read/Write head assembly or degraded magnetism of the servo information on the
platter surface.
        Data recovery from drives with a wide distribution of bad sectors where Logical Recovery software has been
unsuccessful.
        Data recovery from drives with multiple bad sectors or unstable read caused by poor head exchange
        Data recovery from drives whose heads or motors are unstable Recover target data fast when there are
multiple bad sectors or unstable read or bad sectors caused by poor head replacement.
        For hard disk image, DC is the best choice.
What malfunctions Data Compass cannot handle directly
To drives with very severe or complete physical damage, DC cannot recover data directly. The following are some
examples:
        PCB burnt
        Complete head or motor damage
        Severe scratches on the disk data areas
        The HDD was overall cleared or the target data area was covered.
        The data in the data area cannot be viewed by DC

 The Hitachi SA Analog technology of Data Compass can initialize the HDD SA by uploading built-in rescore files,
thus avoid the problem of  can't reading the modules due to SA bad sectors. After the HDD SA initialization, you
can read the P-list and G-list modules and access the data area. However, this technology is now only open for
Hitachi drives, one need to do hot swap for other brands HDD with bad sectors in SA. This tutorial takes an
example of Maxtor drive to introduce how to recover data by using HD Doctor for Maxtor and Data Recovery Hardware with the hot swap method. (DONOR drive: Model: 6E030L0, S/N: E10JR6SE   Code: NAR61590; PATIENT drive  Model: 6E030L0, S/N: E10JS0NE, Code: NAR61590. The DONOR is a drive in good condition, while the PATIENT drive is one with bad sector in SA, can t be recognized in BIOS and can t be repaired by downloading the firmware.)

The principle of Hot Swap is to load the firmware to the RAM after hard drive power on and initialization in order to access the data area of patient drive.  There need two hot swaps to recovery data using Data Compass. In the first hot swap, you need to write the coding list of the patient drive to the healthy drive with the help of HD Doctor for Maxtor, which requires that the coding list module of PATIENT drive (24/55/120) or the factory P-list module(51)is not damaged. In the second one, you need profession data recovery hardware Data Compass to copy the data. Please check the detailed steps below:
To connect the DONOR to the HD Doctor for Maxtor to do the first hot swap, reading the DONOR coding list module or the factory P-list module. First of all, you should make sure the power supply and all cable connections are normal because in the whole process of hot swap, there should be no power break, otherwise the content in the< RAM will miss. Secondly, you had better put the DONOR and the PATENT abreast so easier to do PCBA swap.
