A drive family name is too broad for this fix. The kernel matches exact identification strings, and unrelated resets still require their own diagnosis.
Which drives the table names
The July WD Green change and two hard-drive entries add the NOLPM quirk for problematic link power management. The released v7.2 table includes a fourth entry added in August:
| Identification string | Quirk |
|---|---|
| WDC WD100EFGX-68CPLN0 | NOLPM |
| WDC WD102KFBX-68M95N0 | NOLPM |
| WDC WD141KFGX-68FH9N0 | NOLPM |
| WD Green 2.5 480GB | NOLPM |
NOLPM disables link power management for the matched device. These entries are not the older special handling limited to a problematic link-speed case, and they do not cover every product sold under the same color branding.
Diagnose without widening the workaround
Start by recording the device’s full model and firmware revision, the running distribution kernel and the timestamps of resets. A marketing label or capacity alone cannot establish a table match. Distribution backports can also matter: a version number by itself does not tell you whether the patch is present.
Keep the original logs before changing settings. Compare errors with idle/wake cycles, but also inspect cable connections and power delivery. Link resets can have more than one cause; finding the drive in this table is not proof that every fault comes from power management.
Globally disabling LPM for all SATA devices broadens the effect beyond this targeted kernel fix. It can change power behavior on unaffected drives and makes the comparison less controlled. Prefer establishing whether the distribution already carries the relevant quirk before adding persistent boot options.
We have not measured energy use or reliability on these drives. No wattage saving, performance gain or guarantee against data loss follows from the table alone. Preserve backups regardless of the workaround; a successful test does not replace them.
September 8: list exact matched models, include the later fourth entry in v7.2, and remove blanket boot-parameter advice and unsupported power estimates.
