Gunther,
HD disks AFAIK won't work at all in any DD drive - the TPI (Tracks Per
Inch) are different. DD disks are 48TPI, HD disks are 96TPI. You need to
find DSDD (or at least SSDD if the drive is SS) to be used on your 1541 or
1571.
(Some SS disks might work for DS - I used to punch SS disks and turn them
into "flippy" disks for the Apple & Tandy computers - many company's disks
would "work" DS, they weren't verified or guaranteed for DS, however...)
HTH,
