	A notorious issue with vintage '''Quantum and Conner drives''' is the degradation of '''rubber bump stops'''. Over time, these '''turn into a sticky, tar-like substance''', trapping the heads in place and preventing the drive from initializing. Symptoms include '''repeated clicking sounds or the drive spinning up but failing to seek'''.
