koho,

If the error is real, the drive is scrap. The partition table is stored there and cannot be moved.
The kernel reads that block to discover where the partitions are on the drive.

Is the error real though or do you have a software set up issue?

I think it's a real error, It was working hard all night long (amule+bittorrent) and probably it became too hot and something failed.
In the morning I found some errors and wasn't able to enter in it.
I had to save anything from lost+found after running fschk from an alternative superblock.
Actually I can open it with fdisk and write partitions, but I cannot do mke2fs since it gives me an error about not finding the block or something similar.
Then in dmesg I read this error.

How can I get to know if the error is fixable?

thank you

koho,

fdisk only reads and writes to sector 0. It would fail to read/write partition tables if sector 0 were bad.
Also you could not run fsck, since that is run on a filesystem contained on a parition and th find the partitions sector 0 must be read.

If you have recoverd all the data you need try the following
