weird cd-drive behaviour

Hello all,
My cd-drive is behaving weirdly when I insert a cd-rom in it.It reacts
in any of the following ways:
System hangs
Display garbles + system hangs
System turns off immediately
Runs normally!
Also sometimes the system doesn't turn on when I press the power/reset
button.Then I will off and on the UPS then the system turns on before I
press the power button.

Sometimes the system turns on upon pressing the power button,hardisk
activity seems to happen ,but nothing not-even "POST "messages come up
and the CPU fan keeps rotating.the leds(power+hdd)continue glowing.

Another strange thing that I notice is that :When the system boots up
sometimes the modem(serial) has two leds glowing and sometimes only one
led glowing(I guess 1 led means proper initialization).These leds are
control signals for the modem.CT,...and not power / anything else(venus
modem)

Im unable to figure out the faulty hardware section.But once when I
tried to copy some content from the cd to hdd in linux I recv. the
following error messages:

hdd:command error:status=0x51 {Drive Ready SeekComplete Error}
hdd:command error:error=0x54

After those error messages the system got stuck.Then I restarted the m/c
and the /var/log/messages showed the following two messages at two
different times:

kernel:hda:hda:dma_intr:status=0x51 {Drive Ready SeekComplete Error}
kernel:hda:dma_intr:error=0x84 {Drive StatusError Bad CRC}

I guess there is some system initialization problem.
or DMA problem(last 2 messages}

Please help me in this aspect.Any way to debug further and diagnose and
corner the faulty section?

Thanks in advance.

kaushal.

Some info on your operating system, distribution, version might be helpful.

Must be a Maxtor drive.

m/c?

Hard drive is corrupt and getting seek errors, very common amongst cheap,
Maxtor drives.

Well, try replacing anything yet? My guess is the hard drive, seems how
that is what your OS is trying to tell you. The first problem might be a
CDROM trying to mount to a corrupt /dev node.

Let us know if your hard drive is a Maxtor, what size, and how old is it.

Re: weird cd-drive behaviour

hi Scott,
The hdd is having few bad clusters ,but in the C drive and why should
linux (Win=C,D,E;Linux rest of the disk)report it as a problem.What
about the corrupt /dev node.I couldn't get you.The configuration is:
40GB samsung hdd.
Intel 815E motherboard.
PIII processor.
samsung 52X cd-drive.
Windowx XP
Fedora core-1
Grub.
Can this is a problem due to faulty IDE-slot/IDE-connector?Is there any
s/f or method by which I can test the integrity of my motherboard and
its components?
Thanks in advance.
