I got some hardware failure before, but I don't know how to fix it since I
can't even open a partition tool.

I managed to fix the issue by using "fdisk" and delete all corrupted
partitions from number 20 to 64.

After that, Parted and GParted worked again:

$ sudo parted /dev/sdb

I'm glad you got it working again, hopefully you didn't lose any data.
It looks like things were pretty corrupt, which is why parted crashed
(basically to protect it from making things worse). But I wonder if it
could have been fixed by restoring the backup partition table from the
primary.

If this happens again (hope not!) make a copy of the first and last 1M
of the disk and email it to me so I can poke at it.
