Diagram and Layout |
LinkStation has five LEDs; “Power LED”, “Function LED”, “Info/Error LED”, “Link/Act LED”and “AC adaptor LED”.
| Power LED |
| Display | Status |
| Solid Blue | The LinkStation is powered ON. |
| Blinking Blue | The LinkStation is starting up or shutting down. |
| LED is OFF | The LinkStation is OFF. |
| Function LED |
| Display | Status |
| Solid Blue | DirectCopy is ready (lights for 1 minute). USB device is dismounted (lights for 5 seconds). Lights during initialization. |
| Blinks Blue | DirectCopy is in use. Note:The function LED (blue) and the info/error LED (orange) blink together if an error occurs during DirectCopy. Please do the following if this happens:
|
| Information LED |
The Info/Error LED blinks orange when there is a message. The message is coded by the pattern of blinking.
| Place of information code | Status | Display example |
| 10s place of information code | The LED illuminates for 1.0 seconds every 0.3 seconds. The number of flashes is the tens place of the error code. |
I23 |
| 1s place of information code | The LED illuminates for 0.5 seconds every 0.3 seconds. The number of flashes is the ones place of the error code. |
| Information code | Descriptions |
| I10 | The internal temperature for the LinkStation may exceed the allowable value. Do not place objects in the area around the LinkStation, or install at a cooler location. |
| I11 | The invalid sectors of the hard drive may reach a dangerous level. Replace the hard drive. |
| I12 | The RAID array is being degraded mode. |
| I13 | The RAID array is being formatted. |
| I14 | The RAID array is being checked. |
| I15 | The error status of the RAID array is being investigated. *Data transfers will be slower than usual until this is complete. |
| I16 | The RAID array is being created. |
| I17 | The RAID array is being resynchronized. *Data transfers will be slower than usual until this is complete . |
| I18 | The RAID array is being reconfigured. *Data transfers will be slower than usual until this is complete. |
| I19 | The RAID array is being erased by filling 0 in the array. |
| I20 | Formatting the hard drive. |
| I21 | Checking the hard drive. |
| I22 | Erasing the data of the hard drive. |
| I25 | Updating the firmware. *Do not turn LinkStation OFF during the update. |
| I26 | Initializing the settings in the Web Admin interface. |
| I27 | Checking a USB hard disk. |
| I28 | Formatting a USB hard disk. |
| I32 | Appears when RAID rebuilding or formatting on the web Admin interface is necessary after replacing the hard drive. Rebuild or format the RAID array in the LinkStation’s Web Admin interface. |
| I46 | Data is being transferred or RAID is being migrated. Do not turn off LinkStation. |
| I47 | Data is being transferred or RAID is being migrated. Do not turn off LinkStation. |
| I52 | A new firmware version has been released. Update the firmware. |
| Error LED |
The info/Error LED blinks red to indicated an error. The error may be identified by the pattern of blinking.
Note: The error may also be viewed from NAS Navigator2.
| Place of error code | Status | Display example |
| 10s place of error code | The LED illuminates for 1.0 seconds every 0.3 seconds. The number of flashes is the tens place of the error code. |
E22 |
| 1s place of error code | The LED illuminates for 0.5 seconds every 0.3 seconds. The number of flashes is the ones place of the error code. |
| Information code | Descriptions |
| E04 | Firmware is failed. Contact Buffalo technical support for assistance. |
| E10 | Operating from UPS battery. The LinkStation will be shut down normally. After the LinkStation shuts down. Ensure the power supplied to the UPS, and if there is no problem, turn on the power for the LinkStation. |
| E11 | Fan Error. The fan is spinning too slowly or has stopped. Move the unit to a cool place with good airflow and no objects blocking the fan. If the LED still turns on, contact Buffalo technical support for assistance. |
| E12 | The system temperature has exceeded the safety value. Check that there are no objects around the LinkStation, or install at a cooler location. |
| E13 | An error occurred in the RAID array. Operation will continue, but in degraded mode. Replace the failed drive indicated by the red LED. After replacement, rebuild the RAID array by following the setup screen after starting the LinkStation. |
| E14 | The RAID cannnot be mounted. Perform disk checking of the RAID array on the web Admin interface of LinkStation. |
| E15 | Hard drive cannot be found. The hard drive is not connected, or maybe failed. Set the hard drive again after shutting down the LinkStation. |
| E16 | Hard drive cannot be found. The hard drive is not connected, or maybe failed. Set the hard drive again after shutting down the LinkStation. |
| E22 | Mounting of the hard drive failed. Format the hard drive. If the error still appears after formatting and restarting, replace the hard drive. If the error still appears, contact Buffalo technical support for assistance. |
| E23 | An error occurred, and the hard drive was removed from the RAID array. Click here to see how to solve it. |
| E30 | An error occurred, so hard drive X was removed from the RAID array. Replace hard drive X. For details, see the separate sheet “Hard Drive Replacement Procedure”. |
Note: When the hard drive is failed, the tab of lower part of the failed hard drive glows red when the front cover is opened.
| Link/Act LED |
| Status | Descriptions |
| Solid green | Linking |
| Blinking green | Accessing |

Joseph Lo's Tech Blog 
Hello Joseph, first of all thanks for your extremely informative blog.
I have followed and used several pages for help with my own buffalo Quad Pro since finding it.
I have just had an error on mine and am wondering if you can help – the red LED is blinking indicating that there is a problem in drive 1
My set up is similar to yours but in reverse – Drive 1 is on its own, then three in raid 5 config.
My question is – if the error is in drive 1, can i simply replace this drive without effecting the 3 in raid?
I was under the impression that this was the case then i read somewhere that the buffalo stores setup information on one of the drives somewhere?
Hi Sebastian, I would believe that your data in the raid 5 array is safe given that you said the problem drive is not part of the array. To be safe, I would suggest you first copy the data off the raid array before proceeding further.
After you have done this, you can just go to the Buffalo interface to remove the problem drive 1 and then put in a new drive. This should not affect your raid array.When you put in a new drive, Buffalo should copy the os back to the new drive but this process is transparent to you.
Good luck!
Ah excellent – I have begun this process just in case but hoped it would be that easy.
Thanks again.
Hello,
got an LS WVL today,
If i power it on the blue LED blinks certain times…
After that the red LED (Error/Info) flashes 7 times…
Tested multiple drives and tested without any drives…
What could it be?
Hi Sammy. Try checking what the error represents from the info I posted on this page. If no avail, perhaps do a hard reset and see. Sorry. Not much help otherwise.
Are you Australia Based? Great reviews Please contact me
Hello

Maybe just need an update to b the firmware. Check what nas navigator says. Hope this helps
