12.31.2.2.3 Normalized Values: The device will perform conversion of the raw Attribute Values to trans-
form them into normalized values, which the host can then compare with the Threshold values. A Threshold
is the excursion limit for a normalized Attribute Value. In normalizing the raw data, the device will perform
any necessary statistical validity checks to ensure that an instantaneous raw value is not improperly reflected
in the normalized Attribute Value (i.e., one read error in the first 10 reads being interpreted as exceeding the
read error rate threshold when the subsequent 1 billion reads all execute without error). The end points for
the normalized values for all Attributes will be 1 (01h) at the low end, and 100 (64h) at the high end for the
device which is ready for customer shipment. For Performance and Error Rate Attributes, values greater
than 100 are also possible, up to a maximum value of 253 (FDh).
12.31.2.3 Off-Line Data Collection Status
The value of this byte defines the current status of the off-line activities of the device. Bit 7 indicates Auto-
matic Off-Line Data Collection Status.
Bit 7 Automatic Off-Line Data Collection Status
1 Automatic Off-Line Data Collection is enabled.
0 Automatic Off-Line Data Collection is disabled.
