You are correct Peter, the exception read something like this: "Folder 85 not found."
I am paraphrasing, but that is the crux of the error. It takes about an hour to produce the error so if you want an exact quote from the exception, let me know and give me awhile. I looked through the nested dirs several times after the crash and they always went from 0 - 84... sure enough, directory 85 had not been created... why I do not know. Doesn't really matter now as the script I posted achieves similar results witout crashing... still slow though. As far as drive throughput, it's my understanding that SATA is theorhetically capable of 150 MB/sec (google for it). However, in practice, one can normally expect a sustained throughput of 60 to 70 MB/sec. The drives are 7,200 RPM... not the more expensive 10,000 RPM drives. I have no idea how RAID 5 might impact performance either. It's hardware RAID on a top-of-the-line DELL server. I am not a hardware expert so I don't understand how *sustained* drive throughput, RPM and RAID together fator into this scenario. -- http://mail.python.org/mailman/listinfo/python-list
