Problems with my hard disk od clonezilla

tgorzka

I wanted to back up my hard drive with clonezilla. Suddenly clonezila told me there were "bad sectors" on the disk. But a check told me:

sudo fsck.ext4 /dev/sda3 -r
e2fsck 1.46.5 (30-Dec-2021)
/dev/sda3: clean, 79657/114417664 files, 22829276/457658367 blocks

What now? can I have the partition checked better?

tgorzka so it would not let you go forward or it will let you go forward with cloning?
regardless, gparted andgnome-disks both offer check/repair options for partitions/drives. Use either of those tools in a live iso USB. I'd say both those tools have mostly worked for me when a filesystem became corrupt....
....but 'sectors' I haven't heard referred to since my windows days. that's blocks and stuff if I remember right

I assume the "bad sectors" here refer to actual disk damage, not filesystem corruption. Hence, fsck won't help. To proceed with the cloning anyway (at your own risk) there's -rescue parameter available on Expert mode.

I will start clonezilla in this mode.
What bothers me, Redorescue 4.0 backs up the drive with no problems.

But thank you for your answers

I understand this. I've seen one app throw hardware errors then the next app sees no disk error. it's got to be the way an app is written re: sensitivities; thresholds; blah. Something triggered the Clonezilla to reject the clone. I would have forced it 10 times in a row til it saw it and accepted it but I'm weird that way. edit: and I would have done that multiple attempts thingy firmly believing I had no disk damage

It probably ignores the bad sectors.

tgorzka

ok, thanks for the replies.
How can I determine if I have bad sectors? Which program can I use for this? And isn't it possible to exclude the defective sectors with a program?

stalebrim

tgorzka Yes, and operating systems do ignore defective sectors. However, they're a sign of disk damage and the disk is probably going to fail in the future.

tgorzka

yeah i think so too. So I'll be looking around for a new hard drive soon. but 2 TB is not that expensive
