Well, one thing that bothers me is that your system is not able to |
16 |
keep the fifo or the drive buffer full, which considering that 32x is |
17 |
only 4.8MB/s, it should be able to. Possibly you have something |
18 |
misconfigured, but I don't know what. |

1. Check your cabling and drive jumpers. (Is this the only device on |
21 |
the secondary channel?) |
22 |
|
23 |
2. Check that DMA is enabled for your hard drive (hdparm /dev/hdX). |
24 |
|
25 |
3. If by chance the drive you are reading from is hdd, use -immed with cdrecord. |

|
27 |
Also, try dropping to 16x or even 8x and see if the results improve. |
