Data collected during product lifecycle phases ranging from the beginning of Life (BOL), to the middle of life (MOL) and the end of Life (EOL) assist designers to make informed decisions in various operational and strategic levels. The specific focus of this paper is to show that the data collected during the usage phase of Hard Disk Drives (HDDs) can be used to identify the failure rates of HDDs. Two sources of data were applied: quantitative data extracted from Self-Monitoring Analysis and Reporting Technology (SMART) software, and qualitative data collected from consumer reviews. The data were analyzed to predict the most reliable HDDS available in the market. Some of the important factors to be considered during manufacturing of an HDD are suggested based on the results obtained.

Prognostics and health management of computer hard disk drives is beneficial from two different angles: it can help computer users plan for timely replacement of HDDs before they catastrophically fail and cause serious data loss; it can also help product recover facilities reuse hard disks recovered from the end-of-life computers for building refurbished computers. This paper presents a HDD health assessment method using Self-Monitoring, Analysis, and Reporting Technology (SMART) attributes. It also presents the state-of-the art results in monitoring the condition of hard disks and offers future directions for distributed hard disk monitoring.

This paper proposed a recycling process for neodymium-iron-boron (NdFeB) magnet scrap from the end-of-life (EOL) of hard disk drives by using hydrometallurgical process. Initial chemical composition of NdFeB magnet scrap was consisted of 25.37%Nd, 6.53%Pr, 0.90%Co, 3.63%B and 63.57%Fe. After de-magnetization and crushing into proper size, magnet scraps were directly leached by H2SO4 solution. More than 90% dissolved into acid solution with remaining small amount of residuals and Ni-coated metal. Neodymium precipitated from leached solution by pH-control to the optimum condition at pH 0.6 using NaOH solution. Solid Nd-precipitates XRD pattern was observed in form of NaNd (SO4)2.(H2O) and FeSO4.(H2O). Elemental analysis of Nd-precipitates by WD-XRF. The precipitates contained 26.50%Nd, 8.46%Pr and 1.19%Fe. In order to elimination of Fe, Nd-precipitates was leached by using H2SO4 solution to dissolve FeSO4.(H2O) into acid solution to obtain high concentration of Nd and rare-earth metals (REMs) compound. As a result, XRD pattern of Nd-compound after Fe-removal confirmed that the high purity NaNd (SO4)2.(H2O) compound was obtained. The final composition of precipitates analyzed by WD-XRF was 26.36%Nd, 8.13%Pr with Fe as low as 0.14%Fe.
