I Appologize right now if there is anyone working for Symantec here...
But I saw Norton Disk Doctor destroying catalogs and valuables info
on so many Mac that I have to say it out loud...(its done)
My friend if you want to take care of your Mac please consider
www.alsoft.com
Product like DiskWarrior will assist you good.
I am not trying to do publicity here but DiskWarrior saved my ass
more than twice. when you purchase the CD it includes a very good
tool to defragment your drive called "Optimizer" wich is slower but
so much better than "SpeedDisk" that require the job of DiskDoctor
way too often and that one still do not understand the Mac structure.
BTW dont worry that DiskWarrior is still sold as a OS 9 software
boot from the CD and it will work beautifully on any HFS+ drives
And to save a HD there is a new tool on the market called Drive 10
from Micromat. It also do an amazing job rescuing drives that been damaged
(I am still testing Drive10 and some feedback from users would be appreciated)
