Multiple KDLs when copying to USB drive

[dsuden]

Using a 160GB IDE drive connected using an external USB adapter box, I can copy a few files without trouble, but when attempting to copy a folder containing 16 GB of data and a significant number of sub folders, Haiku KDL'ed. I was able to exit from it, but after a few seconds, it KDL'ed again, and that happened over and over until I rebooted. I have three screen shots of the KDL information attached to this ticket. I wasn't sure whether to file this under "File Systems" or "Drivers" so apologies if this is posted in the wrong location.
