Generally, the drive failure can be categorized as physical and logical failures but all of them are recoverable.
Logical failure: This is a most common failure in hard drives where file system on the drive is logically damage. Logical damage is primarily caused by
Human error which includes accidental deletion of files, accidentally formatting drive or reinstalling operating system to recover lost data.
Power outages may cause file system structures getting damaged, causing a variety of problems, system crashes, or an actual loss of data.
Virus attack may also corrupt the file system on the drive, resulting in operating system to crash.

2.Do no do multiple boots
3.Do not try to shake the drive as it may cause further damage
4.Do not attempt to reconnect the drive with other computers.

Data Protection & Confidentiality
Disk Doctors guarantees protection of your data throughout the data recovery process, from evaluation to handing data back to the client.
1.Disk Doctor Employees are selected through a rigorous process of selection and follow our strict rules and procedures for handling the client data.
2.Client media is cloned sector by sector onto our own lab media and all the data recovery work is carried out on the cloned media not the original media; this ensures that client’s storage media is always intact.
3.Upon successful recovery Disk Doctors by default keeps a copy of the data for 7days before it gets deleted automatically from our Lab Server. This helps in providing the copy of data again if some thing goes wrong during the transfer of data to client e.g. the data media gets damage or goes missing during the postal process.
4.Our agreement to recover the data includes the clause for protection and non disclosure of data as per legal rules and regulations. If you require separate agreement for data protection and non disclosure, we are happy to sign the agreement.
