Unfortunately, I couldn't read it under FreeBSD because HDD doesn't support LBA addressing and FreeBSD doesn't support CHS anymore. At first I thought that this is right to drop support of such old hardware, but after this commit may be I should write a patch that brings back CHS-addressing support :) -- Aleksandr Matveev
