MACH2 2.5-Inch Serial ATA Solid State Drive
Diagnostic Self Test (DST)
The SSD implements the Diagnostic Self Test (DST) command. DST is invoked with the Send
Diagnostics Page (1Dh). When issued, Byte 1, Bits 5, 6 and 7 (Function Control Byte) select between
the Short Test (001b) and the Extended Test (010b).
The results are reported on the Self Test Results Log page (10h). If the results are zero, the drive
passed the DST. A non-zero value indicates the type of failure found. The anticipated duration of the
DST command can be read on the Control Mode page (0Ah).
Hot Plugging Drive
The SSD can be connected or disconnected during operation. This capability is known as “hot
plugging”. The error recovery procedures will recover from any errors introduced by hot plugging. The
method used by the system to detect the insertion/removal of the SSD is dependent upon scenario.
For example, the backplane may be powered, but the SSD may be in a “quiescent” state. It is
recommended that the user reference the Serial ATA 2.6 Specification (SerialATA International
Organization (SATA-IO), High-Speed Serialized ATA Attachment, February 2007) for an overview of
the terms and scenarios associated with “hot plugging” serial drives.
Notes:
1
Hot plugging under the SATA 2.0 standard is limited to backplane applications and
connections; the SSD cannot be connected/disconnected for cabled applications.
2
The user should avoid hot plugging a SSD that has been configured as a boot drive.
Unrecoverable errors may be introduced by the operating system if the user attempts
to remove a SSD with an OS installed on it.
Repairs
A defective SSD should be replaced. There are no parts, assemblies or subassemblies that can be
repaired individually by the user. Please see the section titled
Certification and Warranty
on the
inside of the back cover page. Unauthorized repairs to the SSD will void the warranty.
Preventative Maintenance
No preventative maintenance is required. The drive is sealed at the factory, and there are no parts,
assemblies or subassemblies that require preventive maintenance on behalf of the user. Please see
the section titled
Certification and Warranty
on the inside of the back cover page. Unauthorized
maintenance to the SSD will void the warranty.
