Hi,

I read somewhere that ide cables should only be 65cm long. There are
some cables that are 90cm long.
http://www.overclockers.co.uk/acatalog/Online_Catalogue_IDE_151.html

Some are just plastic some have some metal braiding round that may
shield them. I have a full tower case the longer cables would be
great. I tried using a longer 90cm ide cable that didn't have metal
braid round it. I found with a gigabyte motherboard and a CD-ROM drive
attached through it. It kept on giving errors. When I switched back to
a 65cm long cable it worked fine.

Do you think that metal braided cables would make a difference?

The web page says "0.45m", i.e. 45cm. Why do you think it's 90cm?

No. But try it and report your results here.

I tried some of these some time ago. I got so many CRC-errors on the
cable that the Linux Kernel decided the disks attached
must be defect and disabled them.

actually ide cables weren't meant to be more than 45cm long. better quality
cables or flat cables might have a better chance of working at that length.
 
SFF-8049 standard for IDE cables says clearly: 18 inches maximum cable
length.
There had been some relaxed standards for CD-ROM devices, but they do not
apply if you connect a hard drive.
It is like overclocking your CPU. It might work - sometimes. For CPU, you
must combat the heat, for long cables - improve signal propagation. Here are
some ideas what to look for:

I have 2 of them in my somewhat large server as the IDE route is all the way
around the centrally mounted mobo pan.

After copying 40GB of files over one and then out across the other there are
no errors, one is braided, the other is red platic. Both werep urchased from
