I have an external 3TB Toshiba drive hooked up to my Time Capsule that is accessed by multiple Mac and PC machines on my network. I'm running 10.6.6 on all Macs and the drive is formatted as Mac OS Extended. It's a media drive and I'm always reading and writing to and from it. All was working fine and I had no problems until around the end of the year. Now, the error "The operation cant be completed. An unexpected error occurred (error code -50)." (also attached) appears while trying to modify or write to the drive. All read activity is normal. Basically, I can still view/read files on the drive and play content, but when I attempt to transfer items to it, the error rears it's head. If I try to copy any file over using the Finder or empty the trash with files from that drive, I get the -50 code and alert. A restart will fix the problem for a little while but then it returns after 30 minutes or so. I've verified and repaired the disk via disk utility, and that didn't yield any results. I've not seen much in the way of solutions out there, so I'm hoping there is someone on here who has seen a similar issue and knows of a fix. I'd rather not move the nearly 3TB of data off of it and reformat if there is a better way. Thanks.
