…just installed the MyBook 2TB on my desktop running Win XP. Seems to be working fine. Am able to create folders and transfer files successfully from my internal hard drives. My problem is w/ PhotoShop 7. I can retrieve image files from the WDMyBook to work on in PhotoShop,. but when I try to save back to the WD I get the message unable to save file because disk is full. Yet, when I open the WinExplorer, the drive appears in my directory tree showing all the files I’ve transferred and also showing 1.8 TB of free space. What’s up with that? I can save mpg files from my video editing program no problem.
