Well, just about all drive manufacturers use the same lubricant, so the lubricant isn't really the problem. Imprimis controls the internal humidity of the drive mechanism itself, so external humidity factors won't affect drive performance. Quantum has some internal humidity control, but apparently not enough. Seagate drives have recently (in the last year or so) been exhibiting signs of having virtually no internal humidity control; I haven't recommended a Seagate drive in over a year's time. >-Howard --- Alex UUCP: {att,backbones}!ucbvax!franny!c8s-an INTERNET: c8s-an%franny.berkeley.edu@ucbvax.berkeley.edu FIDONET: Alex.Lau@bmug.fidonet.org (1:161/444)
