Repair Errors on the PwrPak7 Internal Memory

The internal memory can become corrupt and inaccessible to the PwrPak7. This can happen if there is a sudden power loss when the PwrPak7 is transferring files from the internal memory. This can also happen if there is improper use of the internal memory when connected to a computer.

The PwrPak7 will attempt to repair any errors found on the internal memory. This may result in files being placed in the Lost and Found folder in the root of the internal memory. In the case of severe errors, the PwrPak7 may not be able to repair the errors and preserve user data. When this occurs, the FILESYSTEMSTATUS log reports an ERROR status for INTERNAL_FLASH and the LOG LED is solid red. There are two ways to recover from this condition.

Use a computer to correct the error

  1. Connect a computer to the TRANSFER port on the PwrPak7

  2. Use computer-based tools to repair the PwrPak7 internal memory.

When using computer-based disk recovery utilities, ensure the internal memory remains formatted as FAT32 with a cluster size of 16 kB after the repair.

Use the PwrPak7 interface to reformat the internal memory

This results in a complete loss of data on the internal memory.

  1. Disconnect the computer from the TRANSFER port on the PwrPak7.

  2. From any COM port on the PwrPak7, check the FILESYSTEMSTATUS log.

  3. Wait until the status of the INTERNAL_FLASH reports ERROR or MOUNTED and the LOG LED is on, but not flashing yellow (refer to Table: LOG (Onboard Storage) LED).

  4. Use the MEDIAFORMAT command to reformat the internal memory.

  5. Check the status of the internal memory in the FILESYSTEMSTATUS log.

    When the INTERNAL_FLASH reports MOUNTED and the LOG LED is solid green, the internal memory is ready for use.
