Dear WAMUGgers

I've recently installed OS X 10.1.2 on a DV iMac.

Several days later, on startup, a broken folder icon appeared and that was it... no startup. I could start from DiskTools and select OS 9 startup and that would work, but not OS X.

I have reinstalled all OS X and updates and now it is running well (I trust) but I'm puzzled about the cause of the problem. Can anyone advise please? Will it happen again? Is there a simpler solution than reinstallation?

Interestingly I tried using Disk Tools from the OS X installer and it smugly told me that the disk would have been repaired by Disk Tools at startup and all it could do was to verify it, which it did!

Regards

Reg
