Interesting. LTO divides its tracks into four bands, which it writes from inner to outer (analogous to optical media). See http://www.ultrium.com/newsite/html/about_tech.html for pictorials. Inner bands are inherently more reliable because they are further from the edges, where more things can happen. If you had the opportunity and time to dissect the problem Imation cartridges, you *might* find rippling or the like near one edge. It may also be the case that Imation did not properly create some of the outer servo tracks. We've had problems with Imation 3590 tapes as well, so you may want to stick with The Ultimate Vendor. Don't hesitate to return data-obliterated cartridges to Imation, to incite quality control reviews. Richard Sims, BU
