PowerBook 1400 Update -- TidBITS has received notes from a few readers who have tried to use Disk First Aid and other disk utilities on PowerBook 1400s, but receive a message indicating the PowerBook hard disk is not an HFS disk. (HFS stands for Hierarchical File System, which is used by virtually all Macintosh disks.) This message does not indicate a fundamental problem with your PowerBook 1400; according to Apple, some 1400 systems shipped without a "reference file" these disk utilities use. (I'm puzzled what that file could be, and not having a 1400 I can't easily find out.) Apple has released a simple fix ; if you've seen this problem, apply this update to make disk repair utilities run normally. [GD]

You can make text bigger in Excel by zooming to a larger percentage with the Zoom control in the toolbar, or by selecting the cells containing too-small text, choosing Format > Cells (Command-1), and then setting options in the Font pane. You can also increase the default font size for new sheets by modifying the Size field (next to the Standard Font field) in the General pane of Excel's preferences.
