We have seen a weird problem on our SBS 2008 server recently. The server is a Dell Poweredge T310 with 16GB RAM. There are two external Seagate 2TB drives attached via USB to the back ports. One drive is for server backups using Windows Server Backup utility. The other is for archived storage.
The archive drive is having a problem periodically. A folder on the drive is set as a share for network users to browse historical information. At times, the network users can browse the folder structure but cannot see any of the files in the folders. The files are there and can be seen from the server console.
To fix this problem, the server is rebooted, drive is unplugged from USB then reconnected. Note: we do not see this problem on the external backup drive. Both drives are identical and were bought at about the same time.
Any thoughts on how to chase this down?
