Subject: vcd, .dat files and isofs problem
Date: Fri, 05 Apr 2002 04:04:45 +0800 [thread overview]
Message-ID: <3CACB1DD.2040508@shaolinmicro.com> (raw)
I have problems reading the .dat files from VCD, here is the kernel
logs. I think it is an fs issue, since I am not the only one having the
same problem. In user space, read returns I/O error but I think it is an
fs issue or a cd-rom
driver issue, I have tested with xine vcd player, the vcd can be played
by directly accessing the block device but not through the fs. I tested
the VCD under MS Windows using the same machine and disc and .dat files
can be correctly read, even I use vcdgear win32 to convert the .dat
file to .mpg it is still fine. So it is sure it is not the CD or
hardware problem.
Many VCD's are tested and result is the same. It is likely to be an fs
specific problem. I am running 2.4.17 and lsmod shows isofs is in use.
Here is my log messages.
kernel: hdd: command error: error=0x55
