SERT - Preface The Data Recovery community has long struggled with the problem of drives with seized bearings, especially since the introduction of ‘acoustic’ spacers. As the areal density of drives increase, the problem becomes both more pressing and more frustrating. With the release of SERT from Computer Science Labs, there is finally a proven demonstrable solution. For reasons that will be obvious to anyone with knowledge of the competitive nature of the Data Recovery market, it is not possible at this pre-launch stage to reveal exact details of the tool or its application, but the following information should provide a clearer idea of what is involved. The SERT procedure will need to be carried out within a cleanroom or clean cabinet and will require the person conducting the procedure to be experienced in physical/mechanical recoveries such as read/write head changes etc. SERT involves the use of certain specialist items/devices commissioned by Computer Science Labs together with certain other generic tools and equipment, the correct setting up and calibration of the equipment will form part of the comprehensive training that all SERT customers will receive. The procedure does require the sourcing of spares, with the necessary spares matching criteria forming part of the training. Carrying out the procedure includes taking detailed measurements of key parameters needed to monitor and optimise the procedure and again details of these parameters and the equipment and techniques for their measurement will form part of the training. During commissioning and testing, the procedure has never failed to achieve free and full rotation of the drive platters, but the possibility of other damage or failure of other drive components means that, as with any data recovery technique, recovery of data from affected drives will not always be feasible. However use of SERT has already achieved consistent recovery of previously unrecoverable data. It cannot be overemphasised that the SERT training package is critical to successful recoveries, without it, the equipment alone will not deliver the crucial benefits SERT offers. |
