We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

Hey. I have a problem - i bought a very big lot of drives from which some behaved quite funky but camcontrol or setblocksize worked on all of them but these weird Oracle Sun ones.

When plugged in they spin up just fine, no weird sounds and they do get detected as a drive - but they don't have any usable space. The drives are not reporting their capacity to the systems and tools like setblocksize or camcontrol can't format them. Besides that i cannot interact with them at all with dd or tools that try to write data to them they get detected just fine. Someone said there's a custom firmware running on them which blocks them from being used in another systems. I do only the hardware side of things (building NAS Systems, building Gaming PCs and so on) but i don't have any clues on how to figure out how to make these drives usable. Could anybody help me? I will attach a picture of one of the drives. They all behave exactly the same. Also they worked fine in the oracle system they were before.

guessing they are 520 formated. look up " level1techs 520"

Probably both 520b sectors and locked via scsi reservation.

Either way, a low level format will fix it.
