SubjectRe: Problems Hot-Swapping IDE ATA drives
Dear Daniela,
> There is a problem with PCMCIA<->ATA adapters and "True IDE mode":

Many many thanks to you for the hint - I added the On/Off switch on the adapter power and everything now works fine! I insert cassette, cycle the power and mount the drive - it works!
Once again - many thanks.
