Problems withe hdparm

recently i tried to use hdparm to tweak my computer to work a little faster, but i think it doesn't work properly.

[root@localhost archuser]# hdparm /dev/sdb

/dev/sdb:
 IO_support    =  0 (default) 
16-bit)
 HDIO_GET_UNMASKINTR failed: Inappropriate ioctl for device
 HDIO_GET_DMA failed: Inappropriate ioctl for device
 HDIO_GET_KEEPSETTINGS failed: Inappropriate ioctl for device
 readonly      =  0 (off)
 readahead     = 256 (on)
 geometry      = 1216/255/63, sectors = 19541088, start = 0

any suggestions?

BTW i haven't changed any settings yet.

Re: Problems withe hdparm

These HDIO_GET errors are due to the changes made to the kernel *ATA drivers a while back. They define what DMA this SATA device (even thou it might not be a SATA device) uses.

It's nothing that acctually will affect you unless your planing on downgrading your UDMA speeds.

There is a ton of information about this error as it is fairly common nowadays. Just google it! :-)
