Access to raw SMART data?

Is there a way to get the full (raw) smart data for a disk?

Using esxcli I can get some of the data:-

# esxcli storage core device smart get -d t10.ATA_____Corsair_Force_GT________________________13527920000097950113

Parameter                     Value  Threshold  Worst

----------------------------  -----  ---------  -----

Health Status                 OK     N/A        N/A

Media Wearout Indicator       0      0          0

Write Error Count             N/A    N/A        N/A

Read Error Count              120    50         120

Power-on Hours                100    0          100

Power Cycle Count             100    0          100

Reallocated Sector Count      100    3          100

Raw Read Error Rate           120    50         120

Drive Temperature             29     0          31

Driver Rated Max Temperature  N/A    N/A        N/A

Write Sectors TOT Count       N/A    N/A        N/A

Read Sectors TOT Count        N/A    N/A        N/A

Initial Bad Block Count       N/A    N/A        N/A

But it's not outputting the raw column. Compare this to this output (from a linux machine):-

ID# ATTRIBUTE_NAME      FLAG VALUE WORST THRESH TYPE  UPDATED  WHEN_FAILED RAW_VALUE
  5 Reallocated_Sector_Ct   0x0033   100   100   010Pre-fail  Always   -   0

187 Uncorrectable_Error_Cnt 0x0032   100   100   000Old_age   Always   -   0
190 Airflow_Temperature_Cel 0x0032   070   060   000Old_age   Always   -   30
195 ECC_Error_Rate      0x001a   200   200   000Old_age   Always   -   0
199 CRC_Error_Count     0x003e   100   100   000Old_age   Always   -   0
235 POR_Recovery_Count  0x0012   099   099   000Old_age   Always   -   3
241 Total_LBAs_Written  0x0032   099   099   000Old_age   Always   -   417059068

The raw column gives much more useful info that can be compared/monitored/graphed over time.

Any ideas?

(Machine is a whitebox kind of spec. ESXi 5.5 (free). No RAID card. Drives are connected directly to the Gigabyte motherboard.)
