It seems that if I change the size of blocks to 2048 by mkfs.ext3 –b 2048 /dev/sda1, the problem does not appear.
Is there a way to know by advance what is the best block size for an external device ?
I’m formatting a specific MSC key in ext3. This key sizes 4GB.
When I copy a file which is more than 1GB ( 1024MB), I got many errors “Ext3-fs error ( device sda1): ext3_free_blocks_sb: bit already cleared for block xxxx” when I try to remove it after having sync the copy.
Do you know why I could have this kind of error?
Why the problem appears only on this kind of key ?
What can I do to identify the problem?
It seems that there is no error in the FS (e2fsck done successfully) before removing the key.
