Systems and articles of manufacture for preserving error data on a computing platform that lacks non-volatile storage (e.g., a “diskless” platform) are provided. In response to detecting a platform error (e.g., automatically by hardware, software, or manually by a user when a wait or loop condition is suspected), platform error data may be gathered and temporarily stored in volatile storage accessible on the platform. In order to preserve the platform error data in the event power is lost after the error, the platform error data is transferred to a target system with access to non-volatile storage. Once the target system indicates the platform error data has been stored in non-volatile storage, the volatile storage used to temporarily store the platform error data may be freed-up.
