Request to modify Smart Attribute for SK hynix's SE5110 product

[ksj0312]

Hi,

While using SK hynix's SE5110 product for Smartctl tool, we noticed that there is a difference between the SMART Attendant output from smartctl and the value we set.
I would like to ask you to modify drivenb.h so that we can see the correct SMART attribute through smartctl tool.

• Smart output from smartctl

I would like to ask you to change it so that it can be printed with the following attributes.

1 Raw_Read_Error_Rate
5 Retired_Block_Count ==> Reallocated Block Count
9 Power_On_Hours
12 Power_Cycle_Count
13 Read_Soft_Error_Rate ==> ECC Rate
173 Max_Erase_Count => Per Block Max Erase Count
174 Unexpected_Pwr_Loss_Cnt
175 Program_Fail_Count ==> Average Erase Count
179 Used_Rsrvd_Blk_Cnt_Tot
181 Program_Fail_Count
182 Erase_Fail_Count
184 End-to-End_Error
187 Reported_Uncorrect
194 Temperature_Celsius
195 ECC_on_the_Fly_Rate ==> Reported UECC
197 Current_Pending_Sector
198 Offline_Uncorrectable
199 UDMA_CRC_Error_Count
202 Exception_Mode_Status
203 Run_Out_Cancel ==> Volatile Memory Backup Source Failure
231 SSD_Life_Left
235 Lifetime_Writes_GiB ==> Host Write In GB
241 Lifetime_NAND_Prg_GiB ==> Nand Programs In GB
242 Lifetime_Reads_GiB ==> Lifetime Reads From The Host in GB

Which other SK hynix devices are affected by this change?

Model Family:     SK hynix SATA SSDs
Device Model:     HFS480G3H2X069N
Add. Product Id:  DELL(tm)
Firmware Version: DZ02

Is this Attribute set specific to this (Dell specific?) firmware?

[ksj0312]

There are four model names for the device requesting a change as follows.
1) HFS480G3H2X069N
2) HFS960G3H2X069N
3) HFS1T9G3H2X069N
4) HFS3T8G3H2X069N

This attribute value is not for a specific Firmware (ex. Dell), but is applied to Firmware of our Generic SATAs.
