Warranty
To determine the warranty for a specific drive, use a web browser to access the following web page:
http://www.seagate.com/support/warranty-and-replacements/
From this page, click on “Is my Drive under Warranty”. Users will be asked to provide the drive serial number, model
number (or part number) and country of purchase. The system will display the warranty information for the drive.
2.11.1 Data loss under power interruption with write cache enabled
Drive preserves its data during all operations except in cases where power to the drive is interrupted during write
operations. This could result in either an uncorrected data error being reported, or the entire sector/track becoming
unreadable. This can be permanently recovered by rewriting to the same location on the drive. Additionally any data
present in the DRAM buffer will not be written to the disk media, additionally, the drive will not be able to return the
original data.
In order to prevent this data loss, the host should issue a standby immediate or flush cache command before a controlled
power off operation to the drive.
2.11.2 Storage
Maximum storage periods are 180 days within original unopened Seagate shipping package or 60 days unpackaged
within the defined non-operating limits (refer to environmental section in this manual). Storage can be extended to 1 year
packaged or unpackaged under optimal environmental conditions (25°C, <40% relative humidity non-condensing, and
non-corrosive environment). During any storage period the drive non-operational temperature, humidity, wet bulb,
atmospheric conditions, shock, vibration, magnetic and electrical field specifications should be followed.
2.11.3 HDD and SSD Regulatory Compliance and Safety

2.11.4 Safety certification
The drives are recognized in accordance with UL/cUL 60950-1 and EN 60950-1.
The following regulatory model numbers represent all features and configurations within the series:
SKR002: 1/2D (4TB, 3TB & 2TB Models)
SKR004: 3/4D (8TB & 6TB Models)

Corrosive environment
Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years exposure to light industrial
environments containing sulfurous gases, chlorine and nitric oxide, classes G and H per ASTM B845. However, this
accelerated testing cannot duplicate every potential application environment. Users should use caution exposing any
electronic components to uncontrolled chemical pollutants and corrosive chemicals as electronic drive component
reliability can be affected by the installation environment. The silver, copper, nickel and gold films used in Seagate
products are especially sensitive to the presence of sulfide, chloride, and nitrate contaminants. Sulfur is found to be the
most damaging. In addition, electronic components should never be exposed to condensing water on the surface of the
printed circuit board assembly (PCBA) or exposed to an ambient relative humidity greater than 95%. Materials used in
cabinet fabrication, such as vulcanized rubber, that can outgas corrosive compounds should be minimized or eliminated.
The useful life of any electronic equipment may be extended by replacing materials near circuitry with sulfide-free
alternatives.
