--------------------------+-------------------------------
r41154, GCC4 Hybrid
Example:
{{{
~> dd if=/dev/disk/atapi/2/master/raw of=test.iso
dd: reading `/dev/disk/atapi/2/master/raw': General system error
0+0 records in
0+0 records out
0 bytes (0 B) copied, 0.039913 s, 0.0 kB/s
}}}
Syslog:
{{{
KERN: IOCache: falling back to uncached transfer, offset 0, length 512
KERN: ata 2 error: command failed, error bit is set. status 0x51, error
0x54
KERN: atapi 2-0 error: device indicates transfer error after dma
KERN: check_sense: Illegal request
}}}
The reason I stumbled on this is because I was attempting to do a lseek
and read in an emulator that reads game cds on the raw cd device.
