I'm running 4.0-RELEASE with a Cyrix processor and AMI BIOS. I have a Maxtor 18GB IDE disk as a second disk installed as the slave on the second IDE controller, though I saw similar behaviour when it was secondary on the primary IDE controller. The disk seems to park its heads after 15 seconds of idle time (there's an audible click) and then takes 3 or 4 seconds to ready itself when the next access is requested, which I find quite annoying. I've looked at the Maxtor docs and can't find anything that looks like it would help. The BIOS has disk power management disabled, I can't see any other BIOS settings that look relevant. Potentially relevant bits from dmesg: atapci0: <SiS 5591 ATA33 controller> port 0x4000-0x400f,0xe08000-0xe08003,0x40154000-0x40154007,0x20090140-0x20090143,0x30f0400-0x30f0407 irq 0 at device 1.1 on pci0 ata0: at 0x1f0 irq 14 on atapci0 ata1: at 0x170 irq 15 on atapci0 ad0: 6187MB <FUJITSU MPC3064AT> [13410/15/63] at ata0-master using UDMA33 ad3: 17418MB <Maxtor 91826U4> [35390/16/63] at ata1-slave using UDMA33 acd0: CD-RW <CRW6206A> at ata1-master using PIO4 Any suggestions on how to extend or disable the head park time? Or is this just a Maxtor feature or something?
