Perhaps dma wasn't the problem. Here's the output when I execute hdparm on /dev/hdc (my CD-RW):
/dev/hdc: HDIO_GET_MULTCOUNT failed: Input/output error IO_support = 1 (32-bit) unmaskirq = 1 (on) using_dma = 1 (on) keepsettings = 0 (off) readonly = 0 (off) BLKRAGET failed: Input/output error HDIO_GETGEO failed: Invalid argument When I try to retrieve the read-ahead setting: hdparm -a /dev/hdc I get: /dev/hdc: BLKRAGET failed: Input/output error Does anyone know of a web site where I can research these errors? Or does anyone have an idea, off the top of their heads, why this could be happening?
