Under Linux or FreeBSD use fsck /dev/sda1. If you have more than one
SATA device, substitute the correct drive letter and partition number, such as
sdb2, for sda1.

0027 DCB checksum error detected
Event Type
Error
Cause
The drive’s Drive Configuration Block (DCB) has been corrupted.
The 3ware RAID controller stores certain configuration parameters on a
reserved area of each disk drive called the Drive Configuration Block. As part
of power-on initialization, the 3ware RAID controller performs a checksum of
the DCB area to ensure consistency.
Action
If this error occurs, please contact 3ware technical support at http://
www.3ware.com/support/index.asp for assistance.
0028 DCB version unsupported
Event Type
Error
Cause
The unit that is connected to your 3ware RAID controller was created on a
legacy 3ware product that is incompatible with your new controller.
During the evolution of the 3ware product line, the format of the Drive
Configuration Block (DCB) has been changed to accommodate new features.
The DCB format expected by the 3ware RAID controller and the DCB that is
written on the drive must be compatible. If they are not, this message is sent.
Action
Return the drives back to their original controller and contact 3ware technical
support at http://www.3ware.com/support/index.asp for further assistance.
