I realize this would be slow, but relative to the speed of the IEC protocol, why not swap bufferspace into and out of a couple reserved harddisk sectors? That may cause premature flash failure on flash devices taht arent smart enough to do proper wear leveling, but on a regular magnetic disk I dont see a problem. Impact would be minimal as well, only causing delays while writing data. -jbev On Fri, 14 Dec 2007, Jim Brain wrote: > firstname.lastname@example.org wrote: > > I only have one remark: it will be very difficult to use the 512 bytes > > sectors as they are.
