Question about Sabrent 1 Bay USB 2.0 External Drive Case
When I turn on the power, the indicator light turns green and the unit beeps but the disk doesn't spin. It then continues to beep every few seconds. Is it the case or my hard drive?
I have the same problem with the same enclosure. I found out it is the power supply problem. It worked the first time out of the box. But when the black 12V/5V power supply box heats up, if I turn it off, and on again, my hard drive won't spin up. It had buzz sounds and tried to spin. I think they use a crappy power supply that can't supply enough current during drive spin up when temperature goes up.
My solution is to unplug the whole unit from the wall when you don't use it. That give the crappy power supply time to cool down, so next time when you turn it on, it'll start from cold. This solutoin worked for my 300G Seagate drive. For my smaller WD drive, it doesn't require cold start. I guess it makes sense, as bigger drives require more current to spin up.

Tips for a great answer:
you plug in the power cord is there any lights whatsoever on the computer?
When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the laptop is trying to boot or may have booted, but the screen is not showing for some reason.
Beep tones and blinking lights tells the technicians what is going on with the computer and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).
Maybe your power cord is bad if you don't get anything to happen whatsoever when you press the power button.
you have a Static Charge Buildup. Remove the Power Cord, then Press and
Hold the power button for 30 seconds. After 30 seconds plug the power
cord back in and hit the power button to see if it boots.
your memory is bad or the memory slot is bad.
the Power Cord, Open the Case and remove one of the memory chips. Set the
chip aside then try rebooting the computer. If it boots, then you know
the memory chip you set aside is bad so mark an x on it with an ink pen.
If it fails to boot then move the chip to the next memory slot and try
rebooting. If it fails take the chip out and set it aside, then put the
other chip in and try booting it in both slots. If it boots, just to
verify that the chip set aside is bad, mark an x on it and put it into the open
memory chip slot and try booting.
your power supply is bad. Sometimes there is enough power to make the
power light or some other lights come on but not enough power to make the fan
turn on or hard drive spin.
Below are links and info I found from Dell's Website based on your model.
Controls and Lights Front of computer:
Power button - push button
green light - Blinking green in sleep state; solid green for power-on state.
amber light - Blinking amber indicates a problem with the power supply inside the computer. If the system cannot boot and there is a solid amber light, this indicates a problem with the system board (see "Power Problems" in your Owner's Manual).
four lights on the front panel (see Diagnostic Lights.)
Standby power light
AUX_PWR_LED on the system board
Hard-drive activity light
green light - When the computer is reading data from or writing data to the hard drive.
LAN indicator light

that your RAM is securely seated
One bad lead can cause a computer to continue on a cycle or
to shutdown or fail to detect your hard drive
make sure the lead/s that attach to this drive have a secure seating and are not bad/faulty the light on only tells that its getting power it might not be getting enough power you might test the lead/s or
just replace the cable of the hard disk, when you plugged the external disk drive you got that windows could recognize the USB device change the cable everything should work fine again, sometimes the wires inside the cable will be damaged due to bending or stretching or placing heavy equipment upon the cable,
hope this helps
