External Drive Merge Feasibility Dry Run 2026-05-10 19:00

Summary#

This is a historical dry-run snapshot captured on 2026-05-10 19:00 KST for external-drive merge feasibility. It must not be treated as a current capacity or execution decision without a fresh inventory/rescan.

The dry-run excluded D:\insu_warehouse_data.vhdx and did not scan /home/insu/인수창고/자료 contents. At that snapshot time, the reported drives were: D SZara Healthy ~1.93TB free; E Main1 Healthy ~1.07TB free; F MAIN3 Healthy ~7.20TB free; H Zara1 Healthy ~0.11TB free. Based on those then-current values, MAIN3 -> MAIN1 appeared feasible only after drain/verification, while a blind D/H full merge into MAIN1 was not feasible because MAIN1 had only ~1.07TB free and D/H contained multi-TB data.

Current Validity Warning#

Drive free space, candidate CSVs, and merge feasibility are state-dependent. A later Sagwan review disputes use of this claim as a current decision record and states that capacity/merge feasibility should be rechecked with a fresh inventory. Use this note as dated audit context and safety guidance, not as a live go/no-go.

Current Shallow Catalog Reports#

Generated under E:\_MAIN1_ARCHIVE_MIGRATION\10_drive_inventory\merge_dryrun_20260510_1900: - current_shallow_drive_catalog_summary.csv - current_shallow_same_folder_names_across_drives.csv - current_shallow_same_relative_files_across_drives.csv - current_shallow_latest_300_items_excluding_warehouse_vhd.csv - MAIN1_merge_feasibility_dryrun_20260510_1900.md

The shallow E/F/H depth2 + D top-level catalog found 64 same-folder-name groups across drives and 15 same-relative-file groups. Some timestamps were invalid/suspicious, including year 2100 entries, so timestamp-only latest-wins delete/overwrite was unsafe.

Existing MAIN3 Candidate Set At Snapshot Time#

Existing MAIN3_TO_MAIN1_nonvideo_merge_candidates_20260506_001909.csv had 15,481 files / 755.348GB. Breakdown: archive 195 / 568.858GB, image 8,531 / 102.703GB, other 3,533 / 43.911GB, project_doc 2,057 / 35.025GB, audio 1,165 / 4.852GB. Existing duplicate review had 3,277 rows; 3,271 required hash verification before cleanup and 6 were explicit conflicts.

Decision Preserved From Dry Run#

Do not run automatic latest-by-timestamp merge/delete. Safe path: finish MAIN3 drain, rebuild a fresh MAIN3 inventory, then batch-copy non-video candidates to MAIN1 with temp file + SHA256 source/target verification + manifest, and delete source only after verification. D/H should remain catalog-only or targeted project-folder comparison until MAIN1 has enough free space or a different destination is chosen.

personal_vault/projects/main1-archive-migration/drive-inventory-index.md records the inventory convention that logical drive names such as MAIN1 and MAIN3 matter because drive letters may change.
personal_vault/projects/main1-archive-migration/nonvideo-missing-merge-complete-2026-05-09-1742.md and personal_vault/projects/main1-archive-migration/main3-final-drain-started-2026-05-09-1856.md provide adjacent MAIN3 drain/merge context.
personal_vault/shared/reviews/r_20260510T102904Z_3810d8.md disputes current use of this claim because capacity and merge feasibility are volatile and need latest inventory confirmation.
