IMHO you need
- An understanding of ATA (which is the protocol
equivalent of object oriented cobol)
- The ability to work with vendors (it needs to be someone
at a company because many vendors won't NDA with
individuals even if they are happy with GPL code off
their data sheet)
- Someone who has taste in code and understands how to
beat code into shape without breaking it
- The ability to deduce the other errata the vendor forgot
to tell you about or doesn't want to admit exists for
fear of US lawsuits (I kid you not)
- A good understanding of the block layer and its locking
especially because IDE has a heirarchy of contention
problems:
two drives one bus
two channels one DMA engine
two controllers one I/O at a time
ISA IRQ sharing locks
