When we come to the topic of data recovery from Toshiba hard drives, we know Toshiba laptop drives and Toshiba SCSI drives. The main failure of these drives is the bad quality of bearings lubricant in some of the 2.5 inch families(most often GAS and GAX).
When you encounter this failure, you probably experience the following symptoms:
1, The drive is not found in BIOS
2, You may hear slight ticking or scratching noise as if motor tries to spin up but cannot
3, The drive spins up with loud grinding/buzzing/rattling/whirring noise or in worst case it appears to be dead and doesn’t spin up at all
If you attempt to boot up from such drive or read any data from it you would get “Primary Master Hard Disk Fail” or “No operating system found” or “USB Device malfunctioned” error or “S.M.A.R.T. Capable But Command Failed” or some other hard drive error on boot. All these makes the data inaccessible and laptop usually fails to boot and user get “Hard drive not found” error. For such cases, data recovery professionals usually swap the platters to handle the failure.
Toshiba clicking, knocking or sweeping sound
Toshiba clicking, knocking or sweeping sound is another typical failure of Toshiba hard drives! The drive spins up and the head starts clicking right away with a constant or intermittent sound. This is usually due to a damage to the heads and such cases require the patient disks to be opened in a clean room environment for successful data recovery!
Toshiba Hard drives’ bad sectors is another typical failure too. After some period of time magnetic media the platters are covered with starts to degrade and bad sectors appear. Whenever the drive hits such unreadable bad sector it could start freezing, scratching, ticking and sometimes loud clicking. This leads to further damage to the surface and causes more data loss. As soon as you start experiencing such symptoms while reading important files stop the drive immediately and send it to a data recovery lab. Any further attempts would just add up to the problems.
As some other hard drives, Toshiba hard drives experience heads sticktion to the platter surface. Heads are normally parked on the parking ramp outside of the platters, but sometimes due to a hit or abnormal termination they fail to return to their regular parking position and are left on the surface. Immediately after the motor stops spinning they stick to the ideally smooth surface and it becomes impossible to release them without proper tools and experience. In this case hard drive appears to be dead and in order to retrieve data it needs to be opened in clean room.
