# Aaru major bug advisory
Released: 2022.12.22

## Title
Invalid data for retried audio sectors leading to inaccurate images

## Description

During the QA stage for the next release, it was discovered that retry reads of audio sectors were not taking into account the drive offset.

### Affected images
Images created with all Aaru versions before `5.3.2-lts` or `6.0.0-alpha9`, where audio sectors have been retried, are affected.

### Non-affected images
* Images with retries only in data sectors
* Images with no retries at all

## Impact
The content for retried audio sectors is invalid if the image was generated with the affected Aaru versions.

## Affected versions
- Aaru versions before `5.3.2-lts`
- Aaru versions before `6.0.0-alpha9`

## How to identify affected images
- Image contains audio sectors
- **AND**
- Aaru log file contains: `Correctly retried sector NNNN` when `NNNN` is a sector inside a track designated as audio.

## Resolution
New images should be made with version `5.3.2-lts`. Using alpha versions of version 6.0 is not recommended, except for testing purposes.

Images can be resumed with a manually made resume file where all retried sectors are manually marked as `BadBlock` on it. This will require some work but can significantly reduce the time required to generate a proper dump.
