When it spins down or keeps spinned up behaves exactly as I like it. But: Not to spin up the disk speeds up dir-browsing ~ 2 sec or so, but the drive moves its heads to a "sleep" position when it doesn't read something for about a second. Moving the heads out of this sleep position before being ready for reading (the next dir) takes about 1 second. (One can test this by browsing several directories with a pause of some seconds and browsing through several dirs /very/ quickly, so that the hdd doesn't move the heads to the "sleep" position.) Is it possible to prevent the disk to move it's heads to the "sleep" position? I think of a do_something() method in ata.c that only reads again the last sector that was read and that's called every 0.5 seconds in the loop before spinning down the disk. Bye, Uwe.
