Norton AntiVirus Damaging to Mac OS 8.1 Disks -- Symantec Technical Support has confirmed reports of intermittent disk corruption relating to using Norton AntiVirus for Macintosh, though only under Mac OS 8.1 and only with normal HFS-formatted volumes. Symantec believes the problem relates to Norton AntiVirus Auto-Protect and SafeZone scanning and recommends that Mac OS 8.1 users disable SafeZone scanning until Symantec can come up with a solution. John Christopher, Data Recovery Engineer at DriveSavers, commented that the problem results in the disk catalog, extents, and a portion of the disk (from 25 MB to 100 MB) being overwritten with a pattern of F's. His suggestion for data recovery is to try the UnErase utility with Norton Utilities for Macintosh and scan for file types associated with applications you use. If that fails and you have no recent backup, John noted that DriveSavers has proprietary utilities that can often recover data when commercial utilities fail. [ACE]
iMovie '09: Speed Clips up to 2,000%
iMovie '09 brings back the capability to speed up or slow down clips, which went missing in iMovie '08. Select a clip and bring up the Clip Inspector by double-clicking the clip, clicking the Inspector button on the toolbar, or pressing the I key. Just as with its last appearance in iMovie HD 6, you can move a slider to make the video play back slower or faster (indicated by a turtle or hare icon).
You can also enter a value into the text field to the right of the slider, and this is where things get interesting. You're not limited to the tick mark values on the slider, so you can set the speed to be 118% of normal if you want. The field below that tells you the clip's changed duration.
But you can also exceed the boundaries of the speed slider. Enter any number between 5% and 2000%, then click Done.
