Data recovery what to do

Sadly, drives often arrive that are unrecoverable because of what transpired after the initial crash. So this list is to help anyone who suffers a crash. These are the best things to do before calling a data recovery company.

When Disaster Strikes

 If possible, backup the data immediately.
 If the drive makes scraping, tapping, clicking, or humming sounds do not use utility software.
 Do not power up a device that has obvious physical damage, or is making unusual sounds.
 Shut down the computer to avoid further damage to the drive and its data.
 Do not attempt recovery yourself on severely traumatized drives (i.e., turning the computer off and on, using over-the-counter diagnostic tools), as this may cause further damage or permanent data loss.
