Carlo.
You don't need to reformat... The article (which I read earlier this
evening) suggests reformatting because it is a good time to, not
because of any need. He suggests that a drive should be reformatted
occasionally to get rid of bad sectors, etc.

I've done it myself (of course, not with System 7). I was surprised that MacUser didn't mention this as a possible (and inexpensive) method to have both Sytstems 6 and 7. I wouldn't think that you'd need an upgrade of SilverLining to handle System 7. (But then, I've been wrong before). -bri -- Brian Kenney kenney@hsi.com

Would this not be a first for a MacOS upgrade? Reformatting the HD is _not_ a System 7 requirement, and the author doesn't imply that it is. Quoting without permission: _Make Room for System 7_ by Thom Hogan [Thom is listing the steps involved in installing Sys 7 on an HD] "1. Back up the files currently on your hard-disk drive. ... 2. Reformat your hard disk. Yes, reformat it. And I don't mean by selecting the Erase Disk command from the Finder's Special menu. Use the low-level formatting utility that came with your hard disk. Doing this often cathces the marginal or defective sectors that can cause major problems later. This is especially important if you use your Mac in an environment that changes dramatically [because of temperature or humidity extremes, for example] during the year. Temperature changes can affect the exact placement of the head mechanism by minute amounts that can show up as problems writing to disk. ....[Thom discusses the physical reasons for this, giving a "worst-case- scenario" example]... The solution is to reformat and repopulate the hard-disk drive periodically. Since you're about to install a new System, now is as good ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ a time as any to do so. ^^^^^^^^^^^^^^^^^^^^^^ 3. Install System 7. 4. Add fonts, DAs, and INITs. 5. ...[yadi yadi yadi - rest deleted]..." Nothing there about reformatting being a _requirement_ for System 7. Just a good idea, and a convenient time to do it. <chaz> -- ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ "Must think...bubble pipe will relax me and I think..." - Flaming Carrot clarson@ux.acs.umn.edu AOL:Crowbone

The way I switch between 6.0.5 and 7.0a9 is to use Blesser (available
on better BBSs everywhere) to bless the system folder I want. The
last time I reformatted my disk I decided to forget about multiple
patitions. I just put on one and 7.0a9 seems smoother now.
I remember someone asking at the Developer's Conference whether
Blesser works for switching between 6.x and 7.x. The answer was
"We're counting on it." Sounds like Apple folks have been known to do
this too.
