B.5 HD - Possible Errors Concerning Hardisks/CompactFlashs

Problem:

• the router does not recognize the harddisk at all.

Possible Causes:

• the router lacks drivers for the hd-controller - additional drivers for the controller may be needed. Configure OPT_HDDRV in this case.
• BIOS entry for the disk is wrong.
• Controller is defective or switched off.
• wrong disk is configured for the installation
• Controller is not supported by fli4l. Some controllers may need special drivers not included with fli4l

Problem:

• Installation routine stops
• after a remote update of the opt-archive the router refuses to boot
• Error messages occur while partitioning or formatting the harddisk

Possible Causes:

• IDE harddisks can suffer from cables too long or unmatching
• older harddisks may suffer from wrong PIO mode or transfer rate settings in Bios (or controller) eventually being too fast for the disk.
• IDE-Chipset not suitable

Remarks:

• Problems with DMA eventually can be solved by setting LIBATA_NODMA='no'. (The default is 'yes'). This activates DMA with ATA devices.

Problem:

• fli4l doesn't boot from harddisk after the installation

Possible Cause:

• If booting from a CF module fails check if the CF was recognized as LBA or LARGE by the Bios. Correct setting for modules smaller than 512MB is NORMAL or CHS.
• an Adaptec 2940 Controller with an old BIOS is used and extended mapping for harddisks over 1GB is active. Update the Bios of the SCSI controller or switch mapping.
  

  
  By switching the mapping all data on the disk will be lost!
  
  

Problem:

• Windows error message while preparing of a CF-card: Medium in drive (X:) contains no FAT. [Cancel].

Possible Cause:

• The card was removed from the reader too early / without unmounting. Windows did not finish writing and the file system is damaged. Prepare the CompactFlash again at the fli4l via HD-install.
