I have a server 2008 SBS I have been using 2 1TB external hard drives and I use Windows server back to do Full backups. I use two externals becuase I take one home with me every night and leave the other one to perform the backup.
everthing was working great but a week ago the server stop seeing the drives. if I reboot it sees the one that its connect but if I remove the external and swap it stops seeing it. I dont see them in device manager or disk management. I have unistalled the USB hubs from device manager and scan for hardware changes with no sucess. since I only have one server and its works as exchange, file server, with 3 virtual servers I really cant reboot everyday.
