Modern OSes get unhappy when they have to deal with IO errors from disks. The RL02 disk packs pretty much all had bad sectors somewhere. These can be identified and stored in a factory provided table on the last track of the disk, but it was up to each OS to decide how to handle them. Some skip sectors while others remap them.
In USB Mass Storage mode, save a track of the RL02 for sector remapping and use the DEC written bad sector table. With these, modern filesystems can be written to the disk around the inevitable bad sectors, although this will break SIMH and block level disk backup support for vintage disks.
