Hi All,
Just checking before I buy a new ribbon, that there is nothing more sinister
happening with my secondary IDE controller. Suddenly and with no activity
on my secondary IDE controller there's a noise as if my /dev/hdc (8G ATA
drive) and /dev/hdd (CDWR) are reinitialised - i.e. the mechanical noises
usually observed when the machine is switched on and the BIOS probes the
devices on booting.
Both devices are not mounted and there is no media in the CDWR. This is
what dmesg shows:
=================

=================
The noises and error codes are randomly generated over time.
This is the hdparm outputs:
=================
# hdparm /dev/hdc
/dev/hdc:
multcount = 32 (on)
IO_support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
geometry = 16676/16/63, sectors = 8606545920, start = 0
# hdparm /dev/hdd
/dev/hdd:
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
HDIO_GETGEO failed: Invalid argument
=================
I thought that the CDRW DMA ought to be switched on?
Any advice appreciated.
Hi
Is your PCI bus overclocked ?
