What is the difference between these adaptors and the supported ones? Obviously they may require different drivers, but are the adaptors themselves inherently less capable? One dealer told me that some adaptors are only suitable for "multi-media" and others only work with "disks smaller than 700Mb". He couldn't explain why this was. Is he right? And if so why - do the controllers not support the full SCSI protocol? -- Richard -- "For thousands of years, [homoeopathic magic] was known to the sorcerors of ancient India, Babylon and Egypt, as well as of Greece and Rome, and at this day it is still resorted to by cunning and malignant savages in Australia, Africa and Scotland." - J G Frazer, The Golden Bough
