If a drive has 2TB of capacity then it has remapping of bad blocks built in. If such a drive has bad blocks visible to the OS which don't go away by just writing to them (IE "dd if=/dev/zero if=$FILE conv=notrunc bs=1024k count=1" on an ext4 filesystem) then the drive has a serious firmware issue or it has had so many bad blocks that the reserved list has run out. Either of those is a really serious problem that requires replacing the device before you lose everything. You just need to get a new hard disk if your data matters to you. Ideally get 2 disks in a RAID-1. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/ _______________________________________________ luv-main mailing list -- [email protected] To unsubscribe send an email to [email protected]
