The "position" of this error also seems to be not static. One boot before the one, where I saved the "ls -l" output, the directory "kde" has been unreadable. I unmounted and remounted the disc and immediately after that, all directories have been readable, again. I was able to read exactly this disc with exactly this drive to get the MD5sum of the ISO on the disc. The MD5sum was OK. Even the gpgverify, I did immediately after the MD5sum, was OK. No read errors or any other problems. The major problem is, that this one drove me nuts while installing Slackware, as I always was unsure if this silly installer now installed anything correctly or if I had read errors, again. Why is this error gone after unmount/mount? Why isn't the kernel able to "reread" (retry) a part of the DVD, without the need to remount the whole disc? Thanks very much in advance CU Manuel
