Buffalo Forums

I have had no trouble at all for the past three years with this unit. When my music playback started dropping out, I checked every piece of equipment that I used to play back digitally recorded files. Since I initially had some difficulty in getting the link station updater to update it to 1.7.1, I thought this might be the problem. I did power it down by turning the power switch off. The power indicator light flashed for about a minute and then went out. I waited a couple of minutes and then powered it back up. The power light continued to flash for about 5 minutes and never went solid. I turned the power back off, waited a couple of minutes and powered it back on. This time it flashed for a minute and then went solid.

When I pulled it up on NAS navigator the screen showed me an information ball superimposed on LS-WVL-EM000 and said it was in Emergency mode. The message said to "update the firmware or call tech support". I tried to update the firmware with the following results.

I started the updater with the 1.7.1 firmware, it does two data transfers and installs OK. Does the third 272 MB data transfer successfully but fails during install giving me a code that says.

"LS-WVL-EM000 returns an error (ACP-STATE-FAILURE)  Updating is aborted."

It gives me only the option to cancel. After cancelling it leaves me at the updater panel. I tried to install again with the same result.

I tried to do a forced update, following all the instructions. My concern was that, after making the changes to the .ini file and the updater, I ran the updater.
I got a message saying that if I went any farther it would delete data. I was not certain whether that was firmware data or user data.

So, I need some help getting this straightened out. Please clarify for me whether or not moving forward with a forced update will delete the user data off my hard drives or only the firmware data.

My backup for this NAS is about 6 months behind because of a PC failure and data will be lost if I can't recover this NAS. Please Help!

Use ACP Commander to clear the ACP STAT FAILURE error message (google it!) then update the firmware.

Thanks for the tip. I have read the info on the ACP Commander, but I am unable to find a download location for acp_commander.jar. Can you help with that?

Found and downloaded the ACP Commander. Followed the instructions to remove the /boot file. It appeared to have been removed. Still getting the ACP-STATE FAILURE.

Here is the command line session.
