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. 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. One of them is heads sticktion to the platter surface. Toshiba drives also share some common laptop drives problems. That's usually the only way to retrieve as much data as possible from these LBAs. In our lab we use special imaging hardware tools that are capable of reading raw sector data ignoring checksum check. Any further attempts would just add up to the problems. As soon as you start experiencing such symptoms while reading important files stop the drive immediately and send it to a data recovery lab. This leads to further damage to the surface and causes more data loss. Whenever the drive hits such unreadable bad sector it could start freezing, scratching, ticking and sometimes loud clicking. After some period of time magnetic media the platters are covered with starts to degrade and bad sectors appear. There is one more problem that is typical for all manufactured hard drives: bad sectors. This is a clear sign of a bad head and clean room combined with experience and equipment is essential here for successful data recovery. The drive spins up and the head starts clicking right away with a constant or intermittent sound. This is one of the most difficult and therefore most expensive jobs in data recovery, but in our lab we have our own know-how technology that allows to deal with this problem without opening the drive and helps us keep prices much lower.Īnother quite common symptom Toshiba drives have is clicking, knocking or sweeping sound. Normally data recovery companies would attempt swapping platters is such cases in order to retrieve data. User just wanted to extract data off from the driveĪll this makes the data inaccessible and laptop usually fails to boot and user get "Hard drive not found" error. Doesn't show in Device Manager, probably need reflash firmware. My Toshiba MK2023GAS HDD2187 20GB is spinning with noise, loses patition, drive could not be recognized in Windows. Capable But Command Failed" or some other hard drive error on boot. 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. when holding it next to the ear you might hear slight ticking or scratching noise as if motor tries to spin up but cannot.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.We see this hard drive failure since 2007 with its peak later that year. Main problem with Toshiba drives so far is bad quality of bearings lubricant in some of the 2.5 inch families(most often GAS and GAX). Toshiba is represented on HDD market with laptop and SCSI drives. In as clean environment as possible home (isolated glove box) inspected surface of platters, no apparent damage. Using external HDD enclosure and placing on separate IDE controller. Drive spins up normal for 5 seconds, then starts rhythmic clicking, like a metronome with alternating beats.
