Occasional Files not Transferring to External Hard Drive

[parisikov]

I just bought a 2TB OWC Mercury Elite Pro drive. And I'm passing data (mostly video) onto it from a WD MyBook drive. Both use the Journaled HSF format. I'm on a MacBook Pro (10.5.8).

Problem? Every so often I get a message saying "The Finder cannot complete the operation because some data......could not be read or written." And once this happens, the transfer falls into some limbo land — it won't copy any more but i can't get rid of the "copy" window showing the halted progress. I actually have to reboot just to begin the transferring process with another folder.

So what goes? In the last case, it was some JPG file that appeared to stop the action, usually it's some kind of video file. But I can't find any rhyme or reason to why this occurs, nor can I find any distinguishing characteristic of the offending files.

Any ideas? Thanks.

The files are corrupted, plain and simple. The question is whats causing the corruption. Whats the condition of the internal HD on the machine?

Okay, I found a workaround — imperfect, but I'll take it.

I can transfer these "problem" files from the WD drive to my laptop without any problems at all, and then transfer them from the laptop to the OWC Mercury drive — again without any problems.

I'm in the process of transferring over a lot of video. I've basically transferring all my data from WD drives which have become way too erratic for my liking. So it would be time-consuming to do this with everything. But, at least for the problem files that occasionally arise during drive to drive transfer, I'll use this method (after having to reboot, etc.)
