Hard Drive Knowledge Base

Mechanical hard drives that contain spinning platters make clicking (or ticking) sounds for different reasons. As part of normal functions, the drive will make clicking sounds whenever the computer or the external drive are switched on. You can even hear a recognizable rhythm to the sounds emanating from the drive when it first spins up.

 Beyond these perfectly normal sounds, a hard drive that clicks repeatedly can indicate a problem that could cause serious data loss. If your data is properly backed up, you can typically replace the drive with a new one and restore your data by transferring it to the new drive.

However, if you find that your important files were not backed up, switch off the computer or the external drive as soon as possible and contact Ontrack for a free consultation.

Standard hard drives that contain internal spinning platters require a cleanroom—a special static and dust-free environment that allows technicians to access components inside the drive housing. It is not safe to open a hard drive outside of a cleanroom and doing so allows dust particles to enter the mechanism.

Even airborne microscopic particles can cause the drive to malfunction, and the read/write heads will damage the platter surfaces. This reduces the chances for your data to be recovered and makes future attempts by a professional data recovery company difficult to impossible. If your files are irreplaceable and no backup exists, call us immediately for help.

A cleanroom is a static and dustfree environment that protects a hard drive's platters during the data recovery process. If a hard drive has suffered mechanical failure or physical damage, the sealed mechanism will need to be opened in a cleanroom to access internal components such as the actuator assembly, read/write heads, and the magnetically-coated platters that hold data.
