Hard drive letter disappears after not using drive
I have an external firewire hardrive and after I do not access it for say maybe a day or so the drive letter disappears and I can't access that drive. It does not show in my computer or disk management. The firewire device has the latest driver and says it is working properly.
If I remove the firewire cable and the power then plug it back in it still does not show up.
If I reboot it will show up again and can be used.
My machine is running windows Vista.

go into yr device driver manager and check for Power Saving feature - turn it off.
also, check if yr computer is configured to go to sleep or put the hdd to sleep after ???hrs.
