I am using Ubuntu 10.04LTS (Lucid Lynx) and have a 250 GB Hard Disk (ATA TOSHIBA MK2555GSX). It is mounted on a single device
/dev/sda and use Master Boot Record Partitioning. When I am doing S.M.A.R.T. data and running self-test (through System → Administration → Disk Utility), I am getting SMART Status: Disk has a few bad sectors.
I have been digging through the errors and most of the sites suggested to back up the drive and if possible re-format. Since I have an external hard drive for back up and have bad sectors in my hard disk, I want to know if File Back Up would be the ideal choice rather than Disk Imaging, File Synchronization or other back up choices. I am confused about the exact procedure that I follow without corrupting the back up and ensuring safe restore. Can anybody suggest me the safest and fast-restoring back up method that is available?
Please note that I have several apps installed including Hadoop, Hive, Hbase, Python NumPy, Scipy and Matplotlib packages. I need to reuse them after restore from back up.
Any quick suggestion will be highly appreciated.
NOTE: Also, it has happened that when I am trying to restart my linux, I am getting
Reallocated Sector Count Normalized: 100 Worst: 100 Threshold: 10 Value: 1 sector
Current Pending Sector Count Normalized: 100 Worst: 100 Threshold: 0 Value: 3 sectors
When I am restarting my system I am getting the following message:
fsck from util-linux-ng 2.17.2
