Thanks for suggesting http://www.48bitlba.com/usbharddrives.htm
Have you tried any of the drivers for Win 9x which that page recommends, at www.driveragent.com? The latter contains a vast number of USB
drivers (400 are listed on a search), so it's not immediately clear which are the
appropriate ones.
Did the "more expensive USB enclosure" which you used eventually succumb to corruption?
If it did not, which make/model was it?
