Abstract
The present invention relates to an external storage device, such as a hard disk drive, having a replaceable protection device. In one embodiment, the storage device comprises an overvoltage protection device coupled in parallel with a power adapter. The protection device may be configured to fail in short circuit in the event of an overvoltage condition. In order to make the protection device readily replaceable, it may be located on the storage device such that it is accessible by a user. The storage device is configured to continue operations if the protection device is removed.
