Erase Time Capsule

[raster]

Does anyone know how to erase or format a Time Capsule.
I am unable to throw away the time machine file. IT tells me that "bands" is in use and it will not delete. TIme Capsule also does not appear in Disk utility either. I have also tried to Delete the content using a different machine but get the same message.
Thanks

Enter Manual Setup in AirPort Utility, select the Disks tab, select your TC's HDD and click on Erase.
