# Hardware Validation 004 — Option 1 Complete

## Result

The semantic-merge v5 option-1 run completed successfully on:

- drive: `HL-DT-ST DVD-ROM GDR8050L`
- title: Red Faction II
- media ID: `TQ00501A`

## Output

- sectors: `3820880`
- bytes: `7825162240`
- CRC32: `0babc98e`

The run completed VIDEO-L0, both synthetic filler ranges, the shared game-view
writer, VIDEO-L1, final-size verification, sidecar/resource emission, STOP
UNIT, and eject.

## Redump comparison

The supplied DAT entry for `Red Faction II (USA)` is:

- bytes: `7825162240`
- CRC32: `648a0ce4`
- MD5: `f7a89834924f297f49ba991d350daa63`
- SHA-1: `65b82e08ccadfc4c1318fa3fd8113fd869378496`

Only the byte count matches. The reconstructed image is therefore not
Redump-identical and must not be described as Redump-verified.

The image explicitly contains synthetic zero-filled ranges. Those ranges are a
known reason exact identity cannot be assumed, but the present evidence does
not prove they are the only differing bytes.
