I have old hdd whenever I install ubuntu on these it crashes in between , sometimes it's called bad sector or sometimes read only file system.
I installed a month ago on same drive before this is problem also arrived but it's just installed some times.
But these time don't after many affort , what should I do ?
I think about formate my disk with dd command, is that help to overcome bad sector or I have to formate other way .
Is there is any way to fix from bootable pendrive, you can start linux from that and fix badsector dives then let me know.
You should replace this unreliable disk and reinstall.
