I have an 8 user peer to peer network, all on XP Pro or home with a Buffalo Linkstation NAS and Linksys WRT54GS router. We are using updated Zonealarm Security Suite. Data files have been kept on the Buffalo drive for around 2 years with no problems. Started noticing problems with saving Wordperfect files 2 days ago. The files would be corrupted with a 0kb file size after saving. Other applications (Word 2002, Quattro Pro) can save properly. I can't delete thses corrupted files or any other files on the drive now. I get "Cannot delete 'file'. Access is denied. Make sure disk is not full or write-protected and the file is not currently in use". I have also noticed in Autocad, I have to save the files using the 'Save As' command. If I use the 'Save' command I get a message stating "Unable to save drawing file.dwg.Drawing saved to file.tmp"
No changes have been made that should affect access to this drive. I have carefully gone through the setup of the Buffalo drive. It is open with no security, users or groups. I have run the disk scan utility on the drive and have verified this problem on at least 4 of the pc's, both wired and wireless.
Any help is appreciated.
