Possible Cause
• 1394 I/F connection incorrect
• 1394 I/F board defective
• Controller board defective
• USB connection incorrect
• Controller board defective
• HDD is not initialized
• Level data is corrupted
• HDD is defective
• Harness between HDD and board
disconnected, defective
• HDD power connector disconnected
• HDD defective
• Controller board defective
• Execute 5832 001 to format the HDD and
replace the bad sectors. HDD
replacement is recommended because
an HDD unit that generates bad sectors
is probably of poor quality and performs
poorly.
• HDD defective
• Note: If the bad sectors are generated at
the image partition, the bad sector
information is written to NVRAM, and the
next time the HDD is accessed, these
bad sectors will not be accessed for
read/write operation.
• Data transfer did not execute normally
while data was being written to the HDD.
• HDD defective.
