There is a strange problem that has been encountered with a batch of Seagate drives used in MacBook, they are found to be defective in many of the cases. It has been reported that read/write of the drive gets detached from the drive and then it scratches the disk surface until the MacBook is shut down. In the mean time in few of the cases MacBook crashes and the most important data of the users gets lost. In some cases the hard drive becomes inaccessible.
Seagate drives are the most widely used drives by users in different computers, servers and laptops. But this problem has only been discovered in MacBook. The problem has been submitted to the Seagate and Apple and the following workarounds have been suggested:
1. If the RAM and/or hard drive have been upgraded, then change them back to the stock components
2. If the system is not booting properly keep holding the power button of the battery or AC adaptor connected, until a loud chime is heard.
3. Reset the PMU which involves removing the battery and disconnecting the adaptor and holding the power button for abut 5 seconds. Then again you can attach the battery and adaptor.
But before performing these, a point should be kept in mind that these are not the confirmed solution. They work, but in very few cases and also there is no data is recovered which has been lost due to crashing or due to an immediate shutdown. Even after adopting the above mentioned solutions the drive remains inaccessible due to head crash occurred previously. This problem in few cases can be a cause of disaster as users use them to save very important data and its recovery becomes equally important. So a need for the best solution arises.
The only solution for this problem is to search for a data recovery mac service company which could recover your data in the most suitable way. These services companies adopt several techniques and procedures to recover the lost data in almost all possible cases of hard drive failure which is not possible for a general user.

In case of head crash the head is replaced with the new one and further recovery procedure is followed up. So all you need is to pack up your hard drive in an air tight bag and fetch it to the nearest service center of the company.
