Suddenly one day I got ext3 errors while booting and the 2 ext3 partitions would not mount. Both had bad superblocks. One partition with important data could be recovered using e2fsck but the other had a very bad superblock so I finally formatted it again with ext3. The primary NTFS partition was ok all the time. What are the possible causes for this sudden busting of superblocks? The bad blocks check did not reveal any bad blocks so that part was ok.
What make and model of hard drive? Sometimes some series are faulty--
dealers know about this and have to replace/recall such items
Could also be a faulty power supply--output should be within +- 5% of rating. (intex power supplies though getting cheaper are also lowering the quality) OR the pci card may have become loose leading to voltage/current fluctuation and therefore to data corruption OR the connectors may be loose leading to inconsistency/corruption of the superblocks OR a virus entered from the windows partition while windows was booted OR a bug in the kernel used if a developmental model kernel OR a hardware problem randomly occuring due to kinks in the electric supply
I thought the new linuxes were now using the more modern and better ext4 FileSystems.
Maybe a checklist to eliminate the causes one by one.
My 2 cents. Kussh
