Thanks very much. At the moment, money is an issue. The material I am transferring is on tape tobegin with, so security is not the utmost concern, but I will certainly keep what you say in mind. Although, in any case, I can’t see how I would ever be able to store all my data on the drives permanently. I have several hundred hours of material. But in a few years drives that size may well be affordable. I was under the impression that the new eSATA drives are very reliable?
