This is mostly hooey. If you check with your drive manufacturer--not Apple, but someone who knows--the drives can be oriented any way but face down or on their ends. Almost all are specifically warranted in those three positions only, and no others. Unless Quantum has changed their minds, the Pro80 and 40 are OK on their sides or bottom.

Almost everyone I know does also this. It does help to get the little stands if you have the large-format machine, since it keeps the machine from being knocked over accidentally. This is not so important for the compact-format machines, since the little rubber feet can be moved to the other side, and their geometry is a bit more stable in the first place. anders

Actually, I believe Quantum states that any position MAY be used to mount their disks. My Q280 (the 80 meg version used in original Mac IIs) works just fine upside down. In fact, this is the only position that it won't scream with bearing noise. Apple's warning about side-mounting the Mac II is due to the position of the power supply. It is at the bottom in a side mounted configuration. The heat from the supply will rise to the disk drives instead of being sucked out by the fan. It's better, therefore to place the Mac II on the other side, but then you won't be able to get at the floppy disk drive. The IIcx and IIci have their power supplies on the same side as the disks. No problem at all setting them on their sides! Jack Brindle ham radio: wa4fib/7

The only rule of thumb that I have been told is to format the drive in the orientation of use, i.e if you are going to put the mac on its side, format it in this orientation, don't format it on its bottom and then move it to its side. The idea here is that gravity will affect the way the r/w head arm will pass over the platters. But then again...what do I know? I have had macs in both orientations and reversed the situation without any problems. -- = Enjoy! = = John DeRosa, Motorola, Inc, Cellular Infrastructure Group = = e-mail: motcid!derosaj@uunet.uu.net, n1111@applelink.apple.com = =I do not hold by employer responsible for any information in this message =

That depends on the drive--remember that Apple continues to mix-and-match HDAs all day and into the night. If they have stabilized on the Sony, then, yes, it's probably pretty much like all the other Sonys. Which work fine on their sides.
