Overall condition

All 720 sectors were recovered, but 1 of them needed more than one attempt. That is the signature of media that is still readable but no longer suitable and the signal is weakening in places.

What we recommend. Your data is complete and we have imaged your disk successfully. Because of the originating condition we recommend retiring this disk and not relying on it for future reads, as sectors that need retries today commonly become unreadable within a few years.

Grade limited: all data was recovered, but some sectors needed more than one attempt.

The disk surface

Each ring is one cylinder, drawn where it sits on the physical disk — cylinder 0 at the outside edge, working inwards. Each block is one sector, placed at the angle at which it actually passed under the head, measured from the index hole. Scattered marks mean ordinary age-related decay. Marks that line up into an arc or a streak mean physical damage to the media.

Detected format

Nothing in a flux capture states the physical format. The identification below is inferred from what the decoder found: cylinder count, sector layout, data rate and measured spindle speed. A 1.2MB drive turns at 360 rpm and everything else at 300, which is what separates the two high-density formats.

Signal timing

A Greaseweazle records when each magnetic transition occurred, never how strong it was, so no amount of processing can report magnetic amplitude. What can be measured is timing: how far each transition landed from where the encoding says it should be. On healthy media the histogram below shows three narrow spikes at two, three and four bit cells. As media ages those spikes broaden and begin to merge.

Retry analysis

Where a sector fails its checksum, the captured flux is decoded again with different phase-locked-loop settings and, where available, a different revolution of the disk. No single tuning wins everywhere: a track whose speed drifted wants a loop that tracks aggressively, while a track with localised dropouts wants one that holds its lock and coasts through. The count below is how many sectors each tuning rescued that earlier ones could not.

Decoder profilePeriod / phaseSectors rescued
Steady lock

Slow period tracking with gentle phase correction. Best all-round result on the calibration set.

0.010 / 0.201
Balanced

Moderate tracking. Handles gradual speed drift across a track.

0.020 / 0.400
Agile

Fast tracking for tracks written on a drive running off-speed.

0.050 / 0.600
Coasting

Near-fixed clock. Rides through dropouts without being dragged off frequency.

0.004 / 0.100
Aggressive

Maximum agility. Occasionally rescues badly warped media at the cost of noise sensitivity.

0.100 / 0.800

Affected sectors

Angle is measured from the index pulse, which is what makes physical damage identifiable: a scratch or a mould ring produces failures clustered at similar angles across many cylinders.

Filesystem integrity

The filesystem was parsed directly from the assembled image without mounting it. The kernel driver exists to make damaged filesystems look usable — it prefers the first FAT silently, skips entries it dislikes and reports none of it — which is precisely the information this section is for.

File inventory and checksums

SHA-256 is computed over each file's recovered contents, truncated to the length recorded in its directory entry. Files marked other than intact contain at least one sector that failed verification, or have a damaged allocation chain.

Method and limitations

What was done

The capture was decoded from raw flux timings. A software phase-locked loop converts the intervals between magnetic transitions into a bit stream; sector address marks are located in that stream and each sector's header and payload verified against its own CRC. Where a checksum failed, the same flux was decoded again with different loop settings and against other captured revolutions before the sector was declared unreadable. No data was re-read from the physical disk at any point in this analysis; every figure here comes from the single capture named above, which is why the same capture can be re-analysed indefinitely without further wear on the media.
