How to force a disk to reallocate bad sectors

Courtesy of [How to force a disk to reallocate bad sectors][1].

Sometimes a hard disk is hinting on an upcoming failure. Some disks start to make unexpected sounds, others are silent and only cause some noise in your syslog. In most cases the disk will automatically reallocate one or two damaged sectors and you should start planning on buying a new disk while your data is safe. However, sometimes the disk won’t automatically reallocate these sectors and you’ll have to do that manually yourself. Luckily, this doesn’t include any rocket science.

A few days ago, one of my disks reported some problems in my syslog while rebuilding a RAID5-array:
