[Ti] Mac is completely Down (Platinum Powerbook 1g mem)

[David DelMonte]

Error -36 seems to be related to system cache and occurs when large  
scale transfers (>40GB) are made over daisy chained firewire drives.  
The reason I said "notorious" is that when I called Applecare, the  
tech support guy immediately knew the problem and explained how to  
avoid it.

When it occurs (it is btw, an I/O error), it can hurt the source  
files as well as the target files, as I found out to my chagrin.

Now I keep two copies of stuff. When you have extremely large files,  
that becomes an expensive proposition. The error can occur using any  
form of copy, including SD, Carbon Copy Cloner and Finder.

I'm glad it hasn't happened to you.

I did have enough backup so that I could recover, but I've spent more  
on drives than I have on computers.

One more thing. All drives are tested with both disk utility and  
drive genius. All permissions are kept current.
