Why is my File System no longer available (because of Error -71)?
In case the file system on e.g. a "blue memory module" such as the PCD7.R550, R551 or R561 is filled up to the last byte, it may happen that the memory module can no longer be accessed.
After a file system has been filled up completely the files on this module are no longer accessible after the next reboot of the PCD.
- In case of an FTP access to the PCD, the file system on this memory module (e.g. M1_FLASH:/) is no longer visible.
- In case a "Memory Management" FBox is placed in the Fupla program, the error -71 (FS_FILE_SYSTEM_CHECK_ERROR) is indicated.
The reason for this situation is most likely that the whole memory has been used, and there is no more space left for executing a "compression" of the content of the module (see FAQ 101558 for more information regarding the amount of memory available on the file system).
In this case the firmware detects (at start-up of the PCD), that it is no longer possible to correctly manage the flash (e.g. executing a compression) and therefore avoids accessing the memory module with error -71: "Mounted with Errors".
- If the error happened:
In case no relevant data is stored on the module it can be made accessible by a format of the module (which can be executed by the "Memory Management" FBox from the library "File System").
For formatting the card please set up the parameter "Block size: 1024bytes" in the "Memory Management" FBox. (When you set it to "default" the FBox tries to read the block size from the memory card and of course it fails.)
- In case important data is stored on the module, please contact your local sales office.
- In order to avoid this error:
- Do not fill-up the flash memory module to the last byte (but as described in the manual to 80%
if static data is stored, and to 50% if data is regularly written to the flash module.
- Update the firmware to firmware 1.16.27 and later (or 1.10.61 for older systems); these versions avoid
the situation that the flash is filled up to the last byte (which can lead to the error -71).
- This phenomenon can occur on the following systems or modules:
- PCD3.R550, PCD3.R551, PCD3.R561
- PCD7.R550, PCD7.R551, PCD7.R561
- INTFLASH of a PCD3 Compact or a PCD1.M2
PCD7 / Rxxx
PCD3 / Rxxx
PCD1 / M2xx0
