Paragraph Number

156

The configuration module 352, in one embodiment, may monitor the read bias of each packet read and compare the bias of the packet or other data set to the known bias in response to a read request. In a further embodiment, the configuration module 352 may monitor the read bias of each packet read and may compare the bias of the data set or packet to the known bias in response to a data error, such as, for example, an uncorrectable bit error that the ECC decoder 322 cannot correct, or the like. In a further embodiment, the configuration module 352 may not monitor the read bias of each packet read and may determine and compare the bias of the data set or packet to the known bias exclusively in response to a data error. As described below with regard to the proactive configuration module 424 of FIGS. 4 and 5, in certain embodiments, the configuration module 352 sets or adjusts a read voltage threshold or other configuration parameter proactively, based on storage media characteristics instead of, or in addition to, adjustments based on read data sets or packets.
