If your computer does not detect the hard drive, or it is detected erroneously or incompletely, it can be asserted that the hard drive has a mechanical failure. In these cases software will not be effective; the hard drive will have to be recovered with physical tools in a laboratory. Never open the hard drive yourself, that will almost guarantee it will not be recoverable.
Frequently, when loading the hard drive again it will make a repetitive noise or a sequential beep, or the disk will not spin at all. These means the hard drive has suffered a head crash or a motor failure. Avoid loading it again, because it would damage further the hard drive’s emulsion. It can only be recovered in a laboratory.
Do not try to copy the data to another device. Do not let the computer run verification or restoration processes such as data recovery software, chkdsk or scandisk, disk defragmenters, antivirus programs or integrity checkers. These operations are not effective if the hard drive has been physically damaged; on the contrary, they subject the hard drive to an intensive mechanical work and they will damage it further.
Never write new information nor install a new operative system. Your data will only be recoverable if no new information is written over the space it occupied in the hard drive. Overwriting is irreversible. Unplug your hard drive from the computer and ask Serman for a free quote.
Your hard drive will seem to be “dead”, without any noticeable mechanical activity, and you will not feel the motor spinning. Electronic failures have to be treated in a laboratory; just changing the PCB will not fix them and in some models changing the PCB could seriously modify the hard drive programming.
There might be an electronic or mechanical failure. In every case of electronic failure, the disk stops spinning. If the hard drive has been hit or presents mechanical damage, the motor might be damaged and not spin. Motor failure entails a highly difficult recovery. Avoid any hard drive manipulation, specially opening it.

Logical failures can be found in any hard drive, because they do not affect hardware but software. The device does not have physical damage. It can be caused by formatting, data deletion, boot corruption, partition corruption, virus, files corruption, overwriting, etc.
To reach 100% data recovery it will be necessary to process the content of the hard drive with specific techniques, depending on the kind of damage. If there has been overwriting there will usually only be a partial recovery.

It is usually triggered by electricity fluctuations in power sources of both PCs and enclosures. The hard drive will not have any activity: it will not be detected, nor the motor will spin. It will be apparently “dead”. It can present a burnt smell, characteristic of that of electronic components. Changing the PCB will not fix it, because the PCB has been parameterized with the factory-installed head.
Serman has the technology to adapt the parameters of donnor PCBs to the damaged hard drive. Success rate is close to 100%.

There are different types of mechanical failure, depending on the manufacturer and model of the hard drive:
- Whirring, vibration or motor not spinning.
- It makes a “tac tac” noise and the motor may stop completely.
- The BIOS does not detect the hard drive, or it is detected erratically.
Depending on the seriousness of each case, we will have to apply mechanical support techniques and, in some cases, even transplanting the disks to another hard drive. This is a severe fault. The success rate is above 90%.

The head crash is a very common failure in hard drives from all manufacturers. It can be caused by an external agent (e.g. a hit) or by an internal degradation of the magnetic emulsion. The BIOS does not detect or has difficulty detecting the hard drive. It makes a cyclical and repetitive “tac tac” noise, that may stop after a few attempts. A head crash requires a head transplant in a clean room. Data recovery from a head crash will be affected by the high price of the very specific heads required for the process.
It can be found in all the hard drive manufacturers. It is usually caused by a hit or by a serious thermal imbalance. It can present different symptoms:
- The BIOS does not detect the hard drive.
- The motor shaft gets stuck, making an odd and characteristic whistle, like a musical tune.
- The motor does not spin.
When a motor failure happens, it is necessary to transplant the disks to another hard drive. This is a complex procedure that requires experience and extreme accuracy. A specific equipment will be required in each case. The success rate is above 85%.

SSD devices are becoming more frequent and in the case of Apple laptops are, to this day, a constant. There are many different types. Initially, the SATA 2.5 standard has been the one used more frequently. But nowadays, we are finding more M.2. devices. So, it is logical to anticipate that this standard using PCi access, will impose in the short term. SSD failures are of electronic origin, since there is no mechanic in them. This means that their data recovery process goes through a similar treatment to the one used in memory cards, pend drives, etc.. but with even more complexity. We may find different symptoms such as disappearance of unit, lack of detection and also blank units and even cases of data displaying only partially.
