Solution 1: Get the latest Adaptec ASPI layer

Adaptec offers their ASPI drivers freely for public. They should operate in any Windows version, including XP. There are however a few reports of problems with these drivers. For some reason or another, the latest Adaptec's driver version does not seem to function properly under all environments or circumstances. They are however the official supplier and their newest version should be your primary choice.

Solution 2: Get the Nero ASPI

Nero also offers their ASPI layers for free. They also promise support for USB/FireWire devices. Most programs should operate with Ahead’s ASPI, and there are many positive reports about the performance of this driver. Recently this has been our primary choice of an ASPI driver and I have used is with great success.

Solution 3: ForceASPI

ForceASPI is based on older Adaptec ASPI 4.60(1021) version. This version of Adaptec ASPI refuses to install if there are no Adaptec products installed on the computer (Software or hardware). The ForceASPI package solves this issue by inserting the drivers to the operating system with it’s own installer script.

Get ForceASPI

Adaptec doesn’t promise Windows 2000 or XP compliancy for the driver version 4.60, but public experience is that they work very well, even in Windows XP. We have tried it on many occasions and it has always performed well. There are a few reports on the internet the ForceASPI fixing ASPI related issues, when newer versions have failed.

I would recommend that you try these solutions in this order they have been presented. If latest Adaptec ASPI works for you, or the Nero ASPI then good. If not, then go for the ForceASPI as the last solution. Keep in mind that it is not an official Adaptec product and Windows XP/2000 compliancy is not guaranteed.
