- patch (Pass N) now aborts immediately on transport failure (status=0xFF),
symmetric with the sweep and single-pass mux. Previously a USB-bridge crash
was treated as an ordinary bad sector and the pass hammered the crashed
device sector-by-sector until the per-range watchdog expired. (medium)
- patch AACS recovery reads are now unit-aligned: a mid-unit single-sector
read on an AACS disc was rejected by the decrypting reader (DecryptFailed)
and the sector abandoned without asking the drive. The read is now widened
to the enclosing whole 3-sector unit and the requested window copied out,
leaving all recovery accounting (pos/block_bytes/cursor) untouched so it
cannot desync. Only affected CLI decrypt-to-ISO --multipass re-runs. (low)
- IOCTL_STORAGE_RESET_DEVICE corrected 0x002D1004 -> 0x002DD000 (the old value
decoded to function 0x401 with the access bits cleared, so DeviceIoControl
would fail ERROR_INVALID_FUNCTION instead of resetting). Windows-only. (low)
Adds a transport-failure classification regression test.
A direct disc://→mkv:// single-pass rip drives fill_extents in
skip_errors mode. On a read failure it shrank the batch, retried, and
once bottomed out zero-filled + skipped the unit and continued. A SCSI
transport failure (status=0xFF) is a USB-bridge crash, NOT a skippable
bad sector: the bridge is wedged and every subsequent read fails the
same way. So the loop marched the entire disc at one ~15s bridge-
recovery per probe, producing no MKV — the user-reported 'hundreds of
0x28/0xff warnings, runs forever, Movie.mkv never created'.
Fix: short-circuit to an error on transport failure before any
shrink/skip, even under skip_errors — mirroring the multipass sweep's
transport-failure rule in read_error::handle_read_error. The CLI
surfaces it so the user power-cycles the drive or switches to multipass
recovery. Regression test asserts exactly one read is issued and no skip
is counted (no infinite march).
