Instructions

Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T.) are a monitoring system included within hard disk drives and solid state drives. Its primary function is to detect and report various indicators of drive reliability, anticipating imminent hardware failures before they occur.

Key Codes Relevant to SMART Drive Events

Field
Value
Meaning
Sense Key
0x01
Recovered Error.
ASC
0x5D
Failure Prediction Thresholds Exceeded (SMART)
ASCQ
0x12
Hardware Impending Failure - Data Error Rate Too High

A Sense Key of 0x01 (Recovered Error) means the controller detected and recovered from the error. However, in the context of a SMART event, this does not mean that the condition is benign. The drive is self-reporting a degradation trend that has exceeded a manufacturer-defined threshold.

ASCQ 0x12 under ASC 0x5D maps to "Hardware impending failure data error rate too high," meaning the drive's internal read/write error correction is operating at an abnormally high rate; a strong predictor of failure.

The following example events are from a PowerVault ME event history log. Events on the same drive (Enclosure 0, Slot 5) generated a cluster of related entries within seconds of each other. 
  • On PowerVault ME4 to view event history logs in PowerVault Manager, see Administrators guide Viewing event information
  • On PowerVault ME5 or ME52, in PowerVault Manager use the Support panel (Maintenance > Support) and select the tab to view the system event history.

Example of history log event.

B291  2026-05-18 13:44:39  58  INFORMATIONAL
An event was reported by a disk drive.
(disk: channel: 1, ID: 5, SN: 55S0A093F2QL, enclosure: 0, slot: 5)
(Key,Code,Qual,UEC: 0x1, 0x5D, 0x12, 0x0000)
(Recovered Error, hardware impending failure data error rate too high)

What this means:
The drive itself has raised an internal SMART flag. Event code 58 is an informational pass-through; the controller firmware is logging what the drive reported. The sense code 0x01, 0x5D, or 0x12 confirms this is a SMART predictive failure condition related to data error rate.
 

B292  2026-05-18 13:44:39  55  WARNING
A disk drive reported a SMART event.
(disk: channel: 0, ID: 5, SN: , enclosure: 0, slot: 5)
(sense key: Recovered Error(0x01) ASC: 0x5D ASCQ: 0x12
hardware impending failure data error rate too high)

What this means:
Event code 55 is the controller firmware logging the formal SMART warning on the drive.
 

B293  2026-05-18 13:44:39  314  ERROR
There is a problem with a FRU.
(FRU type: Disk, enclosure: 0, slot: 5, device ID: 5,
related event serial number: B292, related event code: 55)

B295  2026-05-18 13:44:39  314  ERROR
There is a problem with a FRU.
(FRU type: Disk, enclosure: 0, slot: 5, device ID: 5,
vendor: TOSHIBA, product ID: MG10SDA400NY, SN: 55S0A093F2QL, version: EP02,
related event serial number: B294, related event code: 55)

What this means:
Event code 314 elevates the SMART warning to a formal ERROR level and identifies the disk as a Field Replaceable Unit (FRU) that requires replacement. The first 314 event (B293) may not yet contain full drive identity. The second 314 event (B295) includes the full drive details; vendor, product ID, serial number, and firmware version; confirming exactly which drive needs attention.

Corrective action

  1. Confirm the physical location of the drive using the enclosure and slot number reported in the events
  2. Gather a support bundle from the array. 
  3. Contact Dell Support or your local support provider to get the drive replaced.
