Dear Mr. Stevens:

Thanks for your reply.

I installed two WD 1TB Hard Drives when I put my new computer together.
I am having difficulty getting Fedora to recognize and access both of them.
(See emails "Two HDs"). Both of these HDs are new.

I removed the second HD and those errors no longer occur on boot-up. This
tells me that the second HD is the cause of the errors.

Thanks for your help.

Sincerely,

That looks like a drive that's dying. Could be a CD or DVD drive that's
having issues.

To find out what device it is, try:

	# cat /proc/scsi/scsi

Look for the stuff under "Host: scsi4 Channel: 00 Id: 00 Lun: 00". That
should be the device.
