10.17.5 Read Continuous bit
If the Read Continuous bit is set to one for the command, the device shall transfer the requested amount of data to
the host within the Command Completion Time Limit even if an error occurs. The data sent to the host by the device
in an error condition is vendor specific.
10.17.6 Write Continuous bit
If the Write Continuous bit is set to one for the command, and an error is encountered, the device shall complete the
request without posting an error. If an error cannot be resolved within the Command Completion Time Limit, the
erroneous section on the media may be unchanged or may contain undefined data. A future read of this area may
not report an error, even though the data is erroneous.
10.17.7 Handle Streaming Error bit
The Handle Streaming Error bit specifies to the device that this command starts at the LBA of a recently reported
error section, so the device may attempt to continue its corresponding error recovery sequence where it left off
earlier. This mechanism allows the host to schedule error recovery and defect management for content critical data.
10.17.8 Streaming Logs
The Streaming Data Transfer feature set requires two error logs and one performance log. These logs are accessed
via the Read Log Ext command; the information included in the error logs is volatile and is not maintained across
power cycles, hard resets, or sleep. These error logs are 512 bytes in length and retain the last 31 errors that occurred
during any Streaming Data transfer.
10.18 SATA BIST (Built-in Self Test)
The device supports the following BIST modes, and begins operations when it receives BIST Activate FIS.
F - Far End Analog Loopback.
L - Far End Retimed Loopback
T - Far End Transmit only
A - ALIGN Bypass (valid only in combination with T bit)
S - Bypass Scrambling (valid only in combination with T bit)
10.19 SATA Interface Power Management
The device supports both receiving host-initiated interface power management requests and initiating interface
power management. The device initiates interface power management when the device enters its power saving mode
whose power consumption is lower than Normal Idle mode.
10.20 Software Setting Preservation
When a device is enumerated, software will configure the device using SET FEATURES and other commands.
These software settings are often preserved across software reset but not necessarily across hardware reset. In
Parallel ATA, only commanded hardware resets can occur, thus legacy software only reprograms settings that are
cleared for the particular type of reset it has issued. In Serial ATA, COMRESET is equivalent to hard reset and a
non-commanded COMRESET may occur if there is an asynchronous loss of signal. Since COMRESET is
