If you have one, or more likely, two external USB drives connected, one or both of them may be pulling more than its fair share of power allocated to it from the USB port (max 500mA @ 5V per port). Over-current power withdrawal from your Monument's USB port can also be putting your Monument into a reboot loop, with an occasional or solid RED showing in the front LED of your Monument.
If you have drive spin-up issues, please disconnect one of the drives if you have two, reboot your Monument, and see if the problem goes away. If not, swap the connected drive, and reboot, and see if the problem goes away. If you have only one drive connected, and it is trying to spin up but failing, and/or if it is putting your Monument into a reboot loop, you may not be able to use that drive directly with Monument. If this is the case, please ensure that there isn't an occasional or solid RED showing in the front LED of your Monument with no USB drives connected. If there indeed an occasional or solid RED showing in the front LED of your Monument with no USB drives connected, please see this.
If you identify that one or more of your drives are in need for more power than your Monument can provide, you have one these two options:
- Do not use the problem external USB drive, if possible.
- Or use an externally powered USB hub like this, or for even more power, like this. First connect your drive to the USB hub, and then connect the USB hub with its extender cable to one of the ports of your Monument. Make sure that your USB hub is connected to its own power adaptor, and that power adaptor is plugged into a functioning outlet. You can add additional drives to the USB hub as long as it can provide sufficient power, but only a maximum of two of those drives will be usable from your Monument, one as the storage (required), and the other as the backup (optional).
If you are having issues with your hard drives, you may want to consider purchasing one of the following drives that we have tested Monument with:
