Hard Drive

Going in circles
Hard drives are the main storage device used for data storage in computers and robots.
Usually computers use a firmware that requires some hard drive to complete the boot process. See the flash memory entry for more details. Crafting a hard drive together with a RISC-V processor writes an operating system to it:
- 2M hard drive: OpenOS II.
- 8M hard drive: Linux.
Crafting either of these drives with a wrench wipes it back to an empty drive.
OpenOS II and Linux show additional hard drives as /dev/vdb, /dev/vdc and so on. See the guides on how to format and mount them. CP/M does not support hard drives.
Computers have to be shut down before installing or removing this component. Installing it while the computer is running will have no effect, removing it may lead to system errors.
Storage media are not perfect, and a drive left unused for a long time may suffer from bit rot and lose its contents. Format corrupted drives using the wrench. Interestingly, this only seems to happen when there are a lot of storage devices in the world.
