I had a pair of custom 80 conductor udma66 cables custom made for my udma33 use. I bought one 24" long, and another that was 28". Both worked fine in the 2.2.26 era, but were generating a lot of CRC errors with 2.2.10. I had to replace both of them with 18" cables to get the machine to stay alive... though I did run this box with the longer udma66 for months with 2.2.6 without significant issue. So I wouldn't suggest trying to use one for a quick extension.
In general, this has been my experience... That lately the code is very sensitive to the ide cable I am using... in my box with 8 ide interfaces. I believe I've replaced all of my cables at least once ;( ... sometimes more than once... trying to completely get rid of CRC errors. I wonder if with so many ide cables in the box I am getting crostalk between them? Almost all of them run essentially parallel to each other.
