    centos disk hdparm tuning
    I’m running CentOS 5 with a PATA hard drive. I’ve used hdparm to tune the hard disk for better performance, but there are 2 settings that don’t work:hdparm -M 254 /dev/hda gives the error “HDIO_DRIVE_CMD:ACOUSTIC failed: Input/output error”hdparm -d1 /dev/hda gives the error “HDIO_SET_DMA failed: Operation not permitted”What do I need to check to set these? It’s already old hardware so anything I can do to squeeze out more performance would be helpful.Thanks.By request, here is the output of hdp

    hdparm
    I’m having problems with a 2TB drive being visible as a 1TB drive in the BIOS. A little research suggests this is due to HPA.I have booted off a live-CD. The syslog contains the following:[ 2.800165] ata3.00: HPA unlocked: 3907027055 -> 3907029168, native 3907029168I tried using hdparm:ubuntu@ubuntu:~$ sudo hdparm -N /dev/sda/dev/sda:max sectors = 3907029168/14715056(18446744073321613488?), HPA setting seems invalid (buggy kernel device driver?) ubuntu@ubuntu:~$ sudo hdparm -N p390702916
