Here is a copy of the letter I received from Seagate concerninge this drive
The Archive Viper 150e is legacy hardware that should not be installed in a PC faster than a 486-33. The drive has not been manufactured in 10 plus years. The drive uses a proprietary interface card VP402, which is a QIC 02 format.
This drive will not work in NT, Windows 98/95/3.1. It runs in DOS only with Mainstream Software. There are no stand alone drivers. The drivers are installed when the backup program is installed.
I have included a copy of this letter in the zip file.
