Yes. If you have disk errors (not data, disk). It'll be prominent in your logs (if it's a SATA grep for ATA). For your sake I hope I'm wrong or that it's just a loose connection. You may find that the device had problems during boot, and the fsck is 'trying' to fix them - but is unable to access the disk. <snipped> > > The underlying issue is that the driver detects an I/O > error.
