Can't copy data to drive. Error blames source file but that file can be copied to all other drives. When I get passed that error, then it says the disk is not formatted. The disk is readable prior to first error and its readable on other drives. I uninstalled Iomega software, that didn't work. Made sure there is no SCSI conflict, its the only device, changed ID, that didn't work. Don't know what else to do. Please help.
