While in general I'd like to see a combined FS/VM be smarter as you do, on this point I disagree with you. Most drive vendors publish the exact sector counts of each model that they ship, and this should be sufficient for your purposes. As an arbitrary example, seagate lists a number of "Guaranteed Sectors" in their technical specifications for each unique model number. Their 7200.11 500GB drive ST3500320AS guarantees 976,773,168 sectors, which happens to exactly equal the IDEMA amount for 500GB. While rounding down to the next IDEMA multiple might make sense, depending on the technique that could cause you 1GB per device, and i'm sure a lot of people would rather not have that limitation. -- Eric D.
