Yesterday I cloned my old system disk (250Gb WD) to a new disk of same size and manufacturer, using dd:
dd if=/dev/sdb of=/dev/sda
The process seemed to go well, but now when I look at dmesg I see the below messages. What do they mean? My old drive doesn't show these.

I see a similar set of messages for my old IDE hard drive that is also in the computer, but was not involved in the upgrade.
Thanks, Dan

Chris, A search that is actually useful: http://www.google.com/search?q=%22tag+0+cmd+0xb0+Emask+0x1+stat+0x51+err+0x4... yeilds 1-5 of 15 hits (one of which is Dan's email). Hits on Google for some random terms does not equal information, sorry.

I have not had any issues, so I have just ignored them. The little bit of info out on the web seems to indicate the errors are benign. The first hit on my Google search seems to indicate that it is a problem with the drivers for nForce chipset SATA controllers. I have an nForce4 motherboard (Gigabyte, actually, like several posts on that page) and an SATA II drive. What hardware do you have? Everything points to this being not a real issue, so I would not worry about it.

When I searched I got exactly 3 hits. One was in German, one was completely useless. The other was the 2nd link that the below search provided. It gave some general information on what to do, but nothing specific enough.

Jonathan, thanks for the reply.

I have a Gigabyte board too with the nForce4 chip. What is strange is that I have a WD 250Gb hard drive, model JS. It does not return any errors. The drive that returns the errors is a WD 250Gb hard drive, model KS. Go figure.
I haven't had any issues either, so I'm ignoring the errors for now. The LKML thread talked about changing the system scripts to not issue unsupported commands. What system scripts, and change them how? That's the part that wasn't clear to me. I suppose he meant /etc/smartd.conf, but so far I'm not sure how to configure it not to issue unsupported commands.
Thanks, Dan
