TS251 not working anymore

English General
1

My TS-251 suddenly stop working.

Symptoms: not anymore to see on Windows Explorer nor QFile Pro,

Have tried to start without HDD and to clean the RAM without success.

LED for Status and HDD1 are well GREEN

Start procedure goes thorugh 1st black screen (decrompressing Linux, booting the kernel).

Then I reach the 2nd black screen showing “starting” and it stops here.

I have heard about a typical failure mode of this TS25 related to “LPC clock bug”

Do you see other tests to perform to identify the root cause?

Thanks in advance for your help!

LPC death would make the DOM not work (DOM is connected via the LPC bus)

If your NAS goes all the way to ‘booting kernel’, the LPC death seems unlikely.

Firsts things first, What was the disk config (RAID1,0,Spanning JBOD) are there backups (I hope so) and how current are they ?

Hi Dolbyman

Thank you for your prompt answer.

I can only say that I had only one HDD connected so no backup. Does it answer your question ?

I should also maybe mention that the NAS was still working locally in a first step but not anymore remotely.

At that time, the NAS was not anymore to see on Windows Explorer but still available on QFile Pro.

Then I had a look on File Station 5 and the NAS directory was also missing.

I have also checked the SMB configuration : it was 2 or 3.

I then also lost the local access and was not anymore able to reboot.

Do not mix up RAID wih a backup, even with RAID you need a backup.

So you had a single disk, no RAID AND no backup, so what was the plan for the inevitable disk failure ? (a NAS is not magic and prolongs your disk life forever)

Depending how important the data on your NAS is, contact a data recovery specialist to secure the data on your NAS (no, you cannot simply connect the drive to any Windows or Mac computer , they cannot read the drive) As long as the drive still works, chances are good, that the costs are managable. If the drive died, then it will be much much more expensive.

Anything random changes you do to your NAS, could erase the data on it.

Hi Dolbyman

Yes indeed, no RAID and single drive…

This is clearly something I will learn from that !

Do you have any ideas on how to find a data recovery specialist ( in Belgium :flushed_face:).

Other option would be to buy a new NAS SNAP compatible with same HDD in order to plug my current HDD in it for recovery.

Is it realistic?

best regards,

If the OS on the disk has an issue, then a new NAS will also not help.

Europe will have a ton of data rescue specialists, a quick google would help.

Alternatively you can open a ticket with QNAP and explain it to them.

Thank you dolbyman,

I will indeed open a ticket.

Looking on other NAs that could be compatible with TS251: i receive the followig list:

  1. TS‑253A / TS‑253D
  2. TS‑453A / TS‑453D
  3. TS‑451+
  4. TS‑451D
  5. TS‑453Be

Would you have any recommendation on a model?

Regards,

Again, I don’t think it’s the NAS.

best to go with a current model

TS-262
TS-264

Or the 4 bay equivalent

Here is how you open a ticket

(I have removed your non NAS related topic about looking for a belgian recovery company)

Hello,

that are old NAS

The x51+ and the x53Be can have the LPC Death.

The new NAS are the TS-264 or the TS-462/4.

Thanks again dolbyman!

If it is at all of any help, i have the TS-253 pro running still. Almost 2 years ago, i got this same symptom (red flashing, not booting) → LPC issue. Fortunately, it was temporarily solved (need to find the guide again).

While the prediction back then was at most 6 months more life in the device, I’m now close to 2 years in with this fix in place and its still working 100% (i hope i don’t jinx it now…).

But if the worst happens, its nice to know that there are upgrade paths availble that potentially allows you to reuse existing disks at least…

Nobody really knows how long it would take for the signal to degrade further on an individual unit, so not sure where you got the 6 months prediction from

That was something i read on the (old) qnap forums site on this particular subject. Of course, if it is really unknown, I’m happy as i can basically postphone a new hardware upgrade for a little while still (until it becomes unevitable)
