So it seems DS409slim, faked as DS411j, is a bit too slim for DSM v5. So let’s rollback to the official (nearly) supported version.
First thing to do is to decide which DSM v4 to go for. Looking at the Release Notes, 4.2-3211 is the last common firmware version (between 409slim and 411j). Previous version is 4.2-3202
Log in the DS409slim using SSH.
dharma> cp -p /etc.defaults/VERSION /etc.defaults/VERSION.orig
dharma> cp -p /etc/VERSION /etc/VERSION.orig
dharma> cat /etc.defaults/VERSION
dharma> cp -p /etc.defaults/VERSION /etc/VERSION
Download 4.2-3211 firmware for DS411j (http://usdl.synology.com/download/DSM/4.2/3211/DSM_DS411j_3211.pat).
Now, log-in to the DSM Web interface. From the “Control Panel”, go to “Update and Restore”. Click the “Manual DSM Update”. Select the downloaded firmware and click “OK”. Validate the warning message and wait until downgrade is processed. Let the system reboot and get to the DSM 4.2 log-in screen.
In my case, the password was wrecked. So I had to reset the whole syno to be able to log back-in. Once done, you’ll see that the syno is back to DSM 4. From here, you can simply configure your syno back to DS409slim.
# vi /etc.defaults/synoinfo.conf /etc/synoinfo.conf
In my case, I wanted to get as high as possible in the DSM 4 release. So I manually upgraded to DSM 4.3-3827 Update 7. They I modified synoinfo.conf.
No data were lost. And 409slim runs fast again. Great!
My DS409slim is really slow since I faked it as a DS411j and installed DSM v5 on it. An option could be configuration issues. So I decided to reset the whole configuration. But I need to keep all that are stored on the SHR-RAID. It is quite straight forward. But here’s the no-so-short story.

Since I turned my DS409slim into a DS411j, I have access to DSM updates. So tonight, I upgraded from DSM 5.0-4528 Update 1 to 5.1-5004 using the update wizard. So far, everything went OK. On first reboot, I was recommended to keep my DSM up-to-date using automatic upgrade. As I don’t want my NAS to reboot while I’m working on it, I choose to “Download DSM updates but let me choose whether to install them”.
That’s all about it 🙂
Looking at the DiskStation DS414slim, I discovered that DSM was now available in version 5. But it wasn’t available from the DSM 4.2 control panel on my DS409slim. After a few Internet diggings, I learned that it should be possible to install DSM5 on a DS409slim. The main trick is to fake another DS. Looking at CPUs in Synology’s NAS, you can see that DS409slim and DS411j share the same Marvell Kirkwood mv6281 CPU and 16-bit@DDR2 architecture. That’s the trick to be able to use DSM5 on DS409slim.

The other day, my Syno DS409slim started beeping. It turned out that two of the Toshiba MK1059GSM disks had SMART errors. I wanted to get some new but they are not available any more. After looking at my preferred e-shop, I finally went for Hitachi Travelstar 5K1000 (HTS541010A9E680). It is not listed in “What hard drive models are supported by Synology products?” page. But it seems to be working fine ; for a bit more than three weeks now.
Here’s a small summary about replacing the disks on Synology DS409slim using DSM 4.2 and SHR volume.
