System sees hard drive as an LVM

[patrokov]

I just built a new system (and transferred two older SATA hard drives to the system as secondary data drives).

The problem is that the system sees them as LVMs and I cannot mount them.  The output of fdisk -l is posted below.  Please note that the /dev/dm-01 entry is not even plugged in at the moment.  Apparently, this has something to do with device-mapper, because when I reload the LiveCD (2009.1), all three hard drives are read and accessed with absolutely no problem.

# fdisk -l

Partition table entries are not in disk order

It tried running #dmsetup remove_all, and it did get rid of the /dev/dm entries, but I still can't access /dev/sdb1.  This post describes a similar problem, but his issue was solved with a synaptic update 2 weeks ago.  This has not helped me at all.  http://www.pclinuxos.com/forum/index.php/topic,65388.30.html

Any ideas?
