We bought some time ago an WD External Harddisk and now the Adapter doesn`t work anymore! What can I do?
Try connecting it to a different computer.
Any external storage device has three major parts:
* USB cable
* USB-to-disk-drive adapter
Try a different USB cable.
Disconnect the disk-drive from that adapter, and connect the disk-drive as a "slave" disk-drive in a desktop computer, and see if you can read the files, which implies that the adapter is the part that has failed.
If you cannot read from the disk-drive, check its WARRANTY status. W.D. will replace it, if the warranty is still valid.
Otherwise, W.D. has a "Customer Loyalty" program: find the serial-number of your unit, access their web-site, and purchase another W.D. external storage unit, at a significant discount, by citing the serial-number.
Or, if the adapter is OK, then replace the disk-drive by a new one, and close-up the casing, to create a "revived" external storage device for your use.
