Thanks for the heads up.

I have just installed this and get a warning that write caching has been disabled as I have HD204UI hard drives. It says to update the drive firmware and then I can re-enable it.

I already did the firmware update to the drives but not sure if it didn't work properly or else this is just a generic message that will warn users with these disks.

Anyone else get this?

Ringo, regarding your HD204UI drives. Did you update them one at a time in another machine/PC with data still on them?

I have the same drives but don't want to lose my data.

Thanks for the info.

Yes they updated from a PC and the data was preserved.

Can i enable write cashing on mine? I wasn't sure what it did so left it. Iv got 2x F4 2TB and 1x F3 2TB. Also can I update the DSM via wifi?

Thanks for response ringo.

Samsung,

Only re enable write caching if you have updated your firmware on the drives.

On occasions with the old version of DSM and old samsung firmware on those drives you could lose data. I guess they have implemented the "enable/disable write cache" feature as a precaution for those on the old drive firmware.

As for over wifi you should be fine, I've updated mine over the internet from work in the past

I should imagine it does a consitency check on the update file before it does it anyway.
If you want to be as safe as possible do it via ethernet.

Will the diskstation not pick up that the new firmware has been installed? I know that the version number didn't change when doing the update so maybe the NAS software won't know either.

Thanks for reply. Iv updated all both my F4's which I think worked. The F3 is just outa the box though. what does write caching do?

R5GTT · 3 Mar 2011 at 13:19

I'm just following this thread on the synology forum.

Looks like others have had the write cache disabled on updated drives too. Some have just re enabled it

Write caching enabled should give you better performance so higher transfer rates.

I'm going to install 3.1 tonight then report back after enabling write caching. My drives are patched I think so hopefully its all good.

R5GTT · 3 Mar 2011 at 13:35

My F4 drives are unpatched and been running with write caching with no problems. I'm not going to chance it any longer though so tonight I'll update the firmware and then do the 3.1 update.

I suspect I've had no problems because I have been using a mirrored RAID and from what I've read most people suffering volume corruption have been using some sort of striped type config. Of course I may have just been lucky!

ringo747 · 3 Mar 2011 at 13:39

I noticed when I go to SMART info I saw I column labelled 'in the past'. I ran a few tests and then it disappeared. Disk status is normal.

Hopefully it will be fine.

neil_g · 3 Mar 2011 at 13:41

dont suppose anyone has a link to the latest hd204ui firmware.. the samsung site isnt too useful..

R5GTT · 3 Mar 2011 at 13:44

I've just looked at my smart info, would be useful if anyone gets a chance could post theirs for comparison. Just did the "normal" smart test and both drives read as "normal"

ringo747 · 3 Mar 2011 at 13:45

The red error was in the Spin_Up_Time field on mine.

nice one ta

Well it said it disabled write cache even though its never been enabled but both my drives are supposedly patched so re enabled it and so far so good. It updated a lot faster than i expected.
