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.
