I mean, it kinda sounds like common sense non-Vulcan logic to me.
Hi thanks for that, yes it would be a power fail, the system has no power on off button, people would just pull the mains out. I did consider a UPS. But hoped a PC board might have a power fail circuit, many micro controller boards in the past did.
Could anyone advise on the EXT3, ReiserFS or Transactional file system?
