While of course any hard drive can fail at any time, the frequent failures you appear to be describing should not be happening.
Have you been able to determine if the failures are due to the actual drive assembly that is installed within the external enclosure, or to the interface circuitry that is in the enclosure that is not part of the actual drive, or to the wall wart power supply that most of them use? If you have multiple failed drives of the same type, you may be able to determine that by swapping parts.
Are you using a quality surge suppressor for both the drive and the computer it is attached to?
Have you looked at the user comments on your particular drives at Newegg.com or elsewhere, to see if there are a high percentage of unfavorable comments, and/or reports of failures?
What are the particular makes and models that have failed?
