IF THINGS DON’T WORK… 

 
Cold Boot NAS: Turn OFF, LED’s and fan turn off, wait, Turn ON, what happens? 
Can computer connect to NAS via Navigator program? 
 
1) Confirm on Buffalo’s web-site the compatibility of drive(s) you use 
 
2) Confirm DHCP is enabled and active on router 
 
3) Confirm network functions and wired connections 
 
4) Turn off Anti-virus and firewalls 
 
5) Did LSUPDATER program display the NAS IP Address? 
    - Best to use static IP Address on NAS 
 
6) Confirm drives are seated all the way in to the NAS SATA connectors 
    - Hard Drive will have a spin noise and most have activity LED flashing 
    - SSD’s – most have activity LED in housing connector side, difficult to view 
    - Turn off room lighting and look in to NAS to see LED HDD / SSD activity 
 
7) Attach drive to computer 
    - If you used USB connection to CLEAN before, connect via SATA this time 
    - Re-Run CLEAN using DISKPART 
 
8) Attach drive to computer – start Disk Manager 
    - Drive should report as being “Online” 
    - Drive should be un-allocated – no partitions or formatting 
    - Drive should be reporting “not initialized” 
 
9) Will computer initialize, partition and format drive. And, write/read data? 
 
8) What is the NAS status using Navigator program? 
    - If EMERGENCY MODE is active there are two things to do, depending on: 
 

1) 

What NAS Firmware version is Navigator reporting (bottom right) 

 

 

Did the Firmware update report original version number? 

 

 

Check network communications 

 

 

Re-run LSUPDATER 

 

2) 

If Firmware update version is reporting in Navigator correctly,  

 

 

communications work 

 

 

Double check drive compatibility 

 
I can’t think of much else that could cause install / update problems. Trouble 
shooting is beyond the scope of this document and appears to be a hardware 
issue. If you still have issues, call Buffalo Tech Support.
