Oh, I see. For some reason hdparm decided to use 2 full seconds today, rather than .30 last week. Episode96 also has 2 seconds.

Anyone know why that is? Was hdparm changed during a recent update maybe? I just updated Slack a few days ago...

I also upgraded the version included with Red Hat 9 to v5.4. This is the version I used for the test in my previous post. Maybe this is the reason for that readings...

I have repeated the test and obtained very similar results.

I wonder how I can get hdparm to read CD ROM drives.

hdparm -Tt /dev/cdrom in most cases.

I can't...
