when USB hard drives are not recognized

Post by jthspace » Thu Sep 13, 2007 4:26 pm

Some thoughts based on experiences with clicking as a power starvation condition, as the drives require 1000ma to spin up and many USB ports top out at 500ma. You can sometimes buy what appears to be a bridge cable that delivers the power from two USB ports to a single device. Good luck actually getting a cable, though.

1) I've found that back panel/motherboard USB ports tend to work better than front panel ones.

2) Try each port; some may deliver just enough extra power to get it to work.

3) Don't use USB extension cables. Cable length and intervening connectors decrease delivered current.

4) Defintely try external power if your drive supports it.

5) If you're unsure whether the drive still works try it on other machines (friends, neighbors, etc.) until you get a statistical sample.

6) If you DO get it to work, you may run into file read/write failures. If so go to device manager for the external drive and change its properties under the policies tab (XP Pro) to "optimize for performance" in order to enable read/write caching. Default setting is to "optimize for quick removal" which is fine most of the time but not with a dodgy USB connection.

All these came off a web search - I also discovered a lot of people complaining that external HDD's did or didn't work with VIsta, so you are not alone.

If your caddy supports a power supply, try that or try connecting the HDD to the PC directly. If it works on XP without fault, then I suspect it is a power/vista problem as mentioned above.

Hope this helps

Jeff
