I have a Dell Windows 2008 R2 server that uses USB drives for backups. I swap out the drives once per week.
Around once a month or so, the drive will become inaccessible and show the message "the device is not ready". Swapping in a different USB drive (same manufacturer and model) does not help the issue. Rebooting the server does help it and the device is then properly detected again. This issue doesn't seem specific to any one USB drive.
The issue is that this keeps happening and I have to keep rebooting the server. Since many people use the server, scheduling downtime on a regular basis like this is painful. I like to figure out how to stop it from happening.
Thoughts welcome and thanks in advance for your help.
