<strong>Spectre</strong> Menus<br />

<strong>Atari</strong>'s model SH204 and possibly SH205 hard disks have a bug in<br />

their hardware which can cause problems, which you must fix at this<br />

menu . Briefly, even though there's only one disk drive mechanism<br />

inside the 204/205, the drives respond as though there's two. Thus, a<br />

"ghost" of the first drive shows up. You'll see this as a "repeat" of all<br />

the partitions of the first drive.<br />

To get rid of this "ghosting", disable the second LUN (logical unit<br />

number) on any <strong>Atari</strong> drive, or use someone else's (Supra's, lCD's)<br />

host adaptor, which work properly. There's even rumored to be an<br />

outfit that sells a replacement PAL chip that fixes the bugs in the <strong>Atari</strong><br />

drive; it's called the ADE Chip, and is sold by Berkeley Microsystems.<br />

Format: This brings up the hard disk formatting menu<br />

(see Figure 11). This menu allows you to specify a given hard disk's<br />

SCSI and LUN (logical unit number), and a partition (from 1 to 12,<br />

using the Supra extended partitions scheme). The partition you select<br />

will be formatted into <strong>Spectre</strong>-format hard disks for use only with the<br />

<strong>Spectre</strong>. If you do this, the partition will become unavailable to GEM,<br />

probably for good until a rcformat/rezero. It is no easy task to get it<br />

back to GEM, by the way; we're working on a way to do this, but it's<br />

not complete yet.<br />
