1.0 out of 5 stars Needs a Separate Power Supply, October 15, 2009
This review is from: Velocity Micro VMdrive External DVD Burner (Black) (Personal Computers)
I loved the idea that this drive uses USB power and doesn't require a bulky A/C adapter. However, this is its downfall (for me, at least). On my (big, expensive) laptop, it works great reading disks, but fails spectacularly when burning. Using only the "regular" USB cable, after inserting a blank DVD-R disc (Magnavox brand discs, if you care to know), it constantly disappears and reappears as a device. This happens endlessly, about every 5 seconds. I saw another reviewer here had the same problem. That isn't the aforementioned "spectacular" part of the failure though. Once I plugged in the additional USB-based power cable into another USB port (on another bus; I have two), the disappear/reappear problem went away. However, the moment I started burning my first disc, windows alerted me that there was a USB power surge because a device had drawn too much power from the USB bus. All of the USB devices in that bus then disappeared (including my external backup drive, for instance, which does have its own, separate power source). At first, I was worried that it had either hosed my backup drive or the USB bus in the laptop. Thankfully though, a power cycle brought everything back. I gave it another shot and had exactly the same problem. I then tried one more time (after another power cycle), switching the two USB ports; same thing.

I see some reviewers here have had success with the drive so I suppose it can work in some situations. However, I can testify that there are some situations where it does not work. I would recommend getting an external drive with its own power supply, despite the added bulkiness.
