Hard Disk Drives (HDDs) are widely used for data storage in various applications. However, their failure can result in significant data loss and system downtime. Therefore, accurate prediction of the remaining useful life (RUL) of HDDs is crucial for proactive maintenance and data backup strategies. In this paper, we propose a novel approach to predict the RUL of HDDs using Long Short-Term Memory (LSTM) networks and incorporating weighted loss functions. The proposed model leverages the Self-Monitoring, Analysis, and Reporting Technology (SMART) features of HDDs, which provide valuable information about the health of the drive. We evaluated two weighting approaches that improve the general performance and enhance predictions within a given timeframe. Our experiments showed that the models outperformed traditional methods in terms of Mean Squared Error (MSE) at given time intervals.
