摘要： Accessing data at a memory is described. A request associated with a read or write operation is received, wherein the request includes a logical address associated with the memory. A physical address is generated based at least in part on the logical address. A block of data at the memory that includes data associated with the physical address is determined. Data at the determined block of data and a corresponding set of ECC from the memory are accessed. Whether the accessed data can be decoded based at least in part on the corresponding set of ECC is determined.

摘要： A length of a separator to be skipped on the storage disk is compared with a threshold. The threshold is associated with a maximum value for which a timing loop is able to be paused without causing the timing loop to have inaccurate timing. If the length is greater than the threshold, a first split sector format is assigned to the split sector and that information is recorded. In such cases, a first portion and a second portion both include synchronization information. If the length is less than the threshold, a second split sector format is assigned to the split sector and that information is recorded. In such cases, the first portion includes synchronization information and the second portion of the split sector excludes synchronization information.

摘要： An access instruction associated with accessing a target location in a disk is obtained. A number of units until the target location is accessed is calculated. It is determined whether there is time for the group of logic to transition from a lower power state to an operational state; the determination is based at least in part on the number of units between a current location of a read head associated with the hard disk system and the target location which is different from the current location of the read head and a warm up time associated with the group of logic. If it is determined there is time, the group of logic is put into the lower power state.

摘要： Processing a sequence of data frames in an error correction code (ECC) decoder is disclosed. Processing includes receiving a first data frame in the sequence of data frames, storing the first data frame, initiating processing of the first data frame through the ECC decoder, receiving a second data frame from the input sequence of data frames, storing the second data frame, and initiating processing of the second data frame through the ECC decoder before the first data frame is finished being processed through the ECC decoder.
