Hi, @ Sasi sir: The errors you mentioned are very general and I cannot make anything out of it. But if you suspect hard disk issues, you are completely justified (and of course your immense experience lends it credibilty). Errors caused by a failing hard disk are sometimes very strange and leave the user clueless. The first choice in that case is to use 'fsck' to check file system integrity.
But SMART is better suited to check for the problems you suspect. It is even useful for preparing for hard disk failure in advance. SMART is a semi-standard technology whereby hard disks record their own health information - like temperature, seek error rate, spin up time and a lot of others. This information can be accessed using appropriate software to assess the health of hard drive. In case of GNU/Linux, the package you need to install is -- smartmontools --. Detailed information on how to use smartmontools and analyze its output are available on following pages: http://blog.shadypixel.com/monitoring-hard-drive-health-on-linux-with-smartmontools/ http://www.linuxjournal.com/article/6983 I wanted to give a better explanation, but I can't format the text very well. I apologize for that. However, I can tell you how I used it. I had two hard drives in my system stacked one above other. Twice, the disk on the top failed. So, I used command: sudo smartctl -A /dev/sda From the output, I realized that the upper disks were overheating due to bad air cooling. Apparently, hot air from the lower drive was heating the upper drive. So I reduced the number of drives to one and also added an extra 120mm cooling fan. Smartmontool shows many such parameters - along with their thresholds. If a parameter drops below its threshold, it indicates bad health. Some parameters indicate impending disaster if they fall below their threshold. Others indicate gradual degradation due to poor environment. Anyway, its is useful for assessing and predicting failures. I hope this becomes useful to you. Please let us know about your experiments with it.
