Re: Nexstar

Its normal, and is the signal showing the drive powering/spinning up and down. The drive spins at 7200 rpms, when you power it up or down, its switches onto the speed that best suits  what it's intended to do.

My NexStar CX external drive worked fine until now. When I powered it up this time the power adapter turns a solid blue. Then when I turn the external drive on, the power adapter starts to flash a weak...

I had same symptoms. After wasting two hours, I finally found the HD not making good contact within the enclosure because I have not screwed it in with the frame. It must have broken the connection while I was handling the enclosure. So my suggestion is to check the simple stuff first - connections and loose cables, particularly within the enclosure.

I needed no drivers for my Windows XP Pro.

This is the usual reason:
USB port has 4 pins (connectors). The two at the ends supply 5 Volts to the hard drive (or any other appliance you connect. I don't think there's a problem with those two because you can see the power light on the hard drive.
The middle is for data transfer. If one gets damaged, although the device gets power, the OS cannot recognize the device.
Try changing the USB cable you are using. Connectors in the wire are damaged more easily than those in the device.

Vantec Nexstar 3 HD not being recognized on comp

Hi, I had this same problem - blue light flashing and the drive not being recognised.

The problem was with the power cord, not the drive.

I solved the problem by unplugging the connection on the power cord between the outlet end and the power brick section, and re-plugging them after flipping one of the ends over.

The drive was now getting power correctly and spun up and was recognised as usual.

Nexstar External drive

If neither computers detect it, which is a good form of process of elimination, I would test the cable with a known working. I would then extract the drive from the enclosure. And try mounting into a desktop machine as a slave, or find another enclosure.
