Slide2:
1. How to discuss 1. Survey the each company’s concern regarding
the reliability issues for consumer HDD by a questionnaire,
and discuss it according to priority.
> Temperature :1th/June and 15th/July
> SMART :15th/July and 2th/Sep
> Imbalance :2th/Sep
> Operating Noise :2th/Sep
> Life
> Others
2. Cooperation with IDEMA USA regarding this issues
3. Target and Goal
> Reliability Guideline V1.0 for Consumer HDD
Slide3:
2. Additional SCT CMD Proposal > CE maker requests to unify the condition of mark etc.
of SMART for use with the system.
ex. temperature : 1byte, Resolution,Celsius,
2’s complement number (80h - 7Fh)
Power-On Hours : 2 - 4 byte, Hour
Drive Power Cycle : 2 - 4 byte, number of times
> However the HDD maker has already applied the value of
SMART with the own evaluation tool, therefore we found
out the union of the mark conditions is difficult.
> As the results, IDEMA JAPAN Consumer HDD sub WG
try to standardize the above mentioned items in SCT
(Smart Command Transfer) of ATA8.
Slide4:
Current Situation of SMART Information ＊1:Correct data is culcurated by Attribute and RAW data ＊1 The SMART inf. of HDD has already some types.
And The each HDD Evaluation tool is already related the each SMART data.
Therefore IDEMA JAPAN found out the union of the mark conditions is difficult.
Slide5:
The Results of IDEMA Japan Meeting ＊1 ＊1 ＊1: If HDD is powered down after standby mode immediately, All IDEMA JAPAN members
accept that HDD can not update the Power on hour during standby mode.
＊2: “milisec” means the unit of credit for indication and doesn't mean resolution.
Therfore it is possible to display “ 100msec,1000msec “ etc. ＊2
