Fortunately, they usually involve mostly side-to-side movement, but a rough up-and-down shake could cause a head crash. Both my hard disks were turned on, but not in use, at 5:04PM on the day of the World Series, and they made it through OK -- but with no power, I couldn't tell for a few days, and since then I've been pretty fastidious about shutting the equipment down while it's inactive. (Thank "Bob" for automatically parking heads!) Incidentally, this is also a reason to keep your hard disk horizontal. -- Tim Maroney, Mac Software Consultant, sun!hoptoad!tim, tim@toad.com "Now hear a plain fact: Swedenborg has not written one new truth: Now hear another: he has written all the old falshoods.
