WD 750 My Book: Get get it to stay running or get recognized

Hello,

There are a few reasons this can happen but all relate to the voltage from you AC adapter not getting to the drive as speced. Hard drives will run through continuos reset cycles whenever they fail to recieve proper voltage. One of three things is happening, Your AC adapter is putting out the wrong voltage(can test with a multimeter), one of the voltage regulators on the My Book Circuit board has failed, can be remedied by moving the drive to a new enclosure. Or finally, one of the circuits on the hard drive controller board has failed, this would require the help of a pro.

If you have access to a multimeter, read the voltage statement on the bottom of the AC adapter and test the voltage. If it's well outside of the listed voltage let me know, and state the listed voltage and I will help you source a replacement on eBay.

If the Voltage is good, take the My Book to your local PC shop and have the technicians there move your harddrive to a new enclosure for testing. If it works in the new enclosure, buy it and be on your way.

If the voltage is good and the new enclosure fails to produce results reply back with your location(Country, State and City) and I'll be happy to refer you to a nearby facility that can help recover your files.

Hope this helps FixYa,

Chris
