Hi All, |
| 2 |
|
| 3 |
Just checking before I buy a new ribbon, that there is nothing more sinister |
| 4 |
happening with my secondary IDE controller. Suddenly and with no activity |
| 5 |
on my secondary IDE controller there's a noise as if my /dev/hdc (8G ATA |
| 6 |
drive) and /dev/hdd (CDWR) are reinitialised - i.e. the mechanical noises |
| 7 |
usually observed when the machine is switched on and the BIOS probes the |
| 8 |
devices on booting. |
| 9 |
|
| 10 |
Both devices are not mounted and there is no media in the CDWR. This is |
| 11 |
what dmesg shows: |
| 12 |

================= |
| 65 |
|
| 66 |
The noises and error codes are randomly generated over time. |
| 67 |
|
| 68 |
This is the hdparm outputs: |
| 69 |
================= |
| 70 |
# hdparm /dev/hdc |
| 71 |
|
| 72 |
/dev/hdc: |
| 73 |
multcount = 32 (on) |
| 74 |
IO_support = 1 (32-bit) |
| 75 |
unmaskirq = 1 (on) |
| 76 |
using_dma = 1 (on) |
| 77 |
keepsettings = 0 (off) |
| 78 |
readonly = 0 (off) |
| 79 |
readahead = 256 (on) |
| 80 |
geometry = 16676/16/63, sectors = 8606545920, start = 0 |
| 81 |
|
| 82 |
# hdparm /dev/hdd |
| 83 |
|
| 84 |
/dev/hdd: |
| 85 |
IO_support = 0 (default 16-bit) |
| 86 |
unmaskirq = 0 (off) |
| 87 |
using_dma = 0 (off) |
| 88 |
keepsettings = 0 (off) |
| 89 |
readonly = 0 (off) |
| 90 |
readahead = 256 (on) |
| 91 |
HDIO_GETGEO failed: Invalid argument |
| 92 |
================= |
| 93 |
I thought that the CDRW DMA ought to be switched on? |
| 94 |
|
| 95 |
Any advice appreciated. |
