The ultimate air-gap, long-term storage tier · LTO format confirmed by Dan · likely mLogic mTape / mDrive Thunderbolt enclosure (mLogic mTape2 LTO-6 appears in 2022 eBay correspondence; Hedge Canister archive-management software referenced) · exact model + PSU spec pending rating-plate photo drop
Estimate · EOD · end of deployment
EOD horizon: ~2040-2045 · tapes archival to ~2055+

Tape drives are the longest-lived tier in the storage stack. Why the EOD is so far out: (a) air-gap duty cycle is low — the drive sits idle 99% of the time, so head wear is minimal; (b) LTO has formal backwards-read of N-2 generations and write of N-1, so a working drive stays usable across two new format launches; (c) the secondary market (eBay, B&H used, post-production studio cast-offs) keeps tape drives and PSUs liquid for 15-20 years past OEM EOL; (d) tape media itself is rated 30-year archival per LTO spec. The current PSU failure is a parts-availability problem, not a unit-EOL problem — far less worrying than the QNAP's firmware-support cliff.

Find a replacement PSU — sourcing in progress

Existing PSU has failed or is missing. Next step: drop a photo of the unit + rating plate + existing PSU label (voltage / amperage / connector / polarity) into the zone below. A background research pass is running on Reddit + general web for replacement PSU intel for the likely candidates (mLogic mDrive Thunderbolt LTO most likely); findings will land in the Sourcing notes section once complete.

Stewardship posture

Every tech record sits at one rung of a containment ladder. As vendor EOL approaches and security updates dry up, the unit steps down the ladder rather than being binarily retired — extending its useful life by isolating risk.

Tier 0 · normalFull network access · vendor updates flowing · routine use
Tier 1 · firewalledNo inbound exposure · still pulls updates · still on internet
Tier 2 · CF Access gatedBehind Cloudflare Access · only authenticated identities reach it · no public ingress
Tier 3 · RAID-only · no internetBound to LAN · no outbound update channel · still serves files locally
Tier 4 · LAN-only · no SMB ingressReachable only from a single workstation · no shared mounts
Tier 5 · air-gappedmDrive lives here · powered down between use · tape inserted only for write/read sessions · physically isolated · ultimate cold tier

Air-gap is the terminal posture — there's no rung below. It's also why the EOD horizon is so long: no firmware to patch, no exposure to defend, no SLA to keep. The drive only needs to power on when called and read tapes the format still supports.

Software ecosystemHedge · Canister — macOS LTFS archive-management tool · prior outreach to canister@hedge.co requesting PSU help · no reply received (Dan, search-confirmed 2026-05-26)

OEM PSU patternmLogic Thunderbolt LTO enclosures typically use an external 12 V DC brick · amperage varies by generation (commonly 5-6 A for LTO-6/7 single drives) · 5.5×2.5 mm center-positive barrel is the most common connector for this class
Replacement avenuesDirect from mLogic (preferred — they sell PSU spares for legacy units · email support@mlogic.com) · eBay used spares (mLogic enclosures appear regularly · search "mLogic mTape PSU" / "mLogic LTO power supply") · Mean Well GST60A12-P1J or similar 12 V 5 A medical-grade brick as a generic substitute once spec is confirmed

A background research pass surfaced Iomega MDHD-series intel — discount that lead; Dan confirmed LTO, so we're firmly in mLogic/Thunderbolt territory rather than consumer USB HDD. The Iomega-MDHD intel is parked as a published report — kept on file in case (a) an actual Iomega MDHD surfaces later in inventory, or (b) the failure profile (12 V brick, 5.5×2.5 barrel) matches another household device. Parked-sketch report → Iomega MDHD PSU intel (2026-05-26).
