SDR-5100N stuck in boot loop; will boot and operate normal if HD removed.
Are all WD10EURX- drives the same/interchangable, is the number after the hyphen important?
Does anyone have experience or information about drives, or boot issues?
The Samsung website will NOT accept their own model number! (SDR-5100N)
It is less than 7 yrs old!
Any tips would be appreciated.
Mr K L
I learned from WD support that the HD model number after the hyphen are revisions, and should be interchangable. Functionally the same.
[I UPDATED AGAIN BELOW 7-8-19, so ignore these models, see below] WD also recommended the WD Gold or Red HD as current replacement. (compatibility unconfirmed, but sounds like correct advice).
I still hope someone else that has this issue will share what they know or did about it. (eg., HD or MB issue, or both...)
Contacted Wisenet (support for security cameras, -ie. for this item)
Wisenet provided me with compatible HD models:
Western Digital drives:
their model numbers:
These have been tested for compatibility.
Hanwha Group bought Samgung Techwin (Samsung's security camera division).
Wisenet is a brand name of Hanwha Techwin.
(Wisenet has assumed support for Samsung Techwin products)
(Samsung Techwin's bigger sister company, Samsung Electronics, was not part of the takeover, and is apparently still Samsung Electronics)

Unfortunately these models are no longer supported by most Samsung teams. We recommend reaching out to your retailer or service provider for further assistance. I truly apologize for any inconveniences caused.
Thank your for the very quick response!
I am thrilled at the fast answer, from a moderator too.
As much as I want to accept as best answer, I want to leave this open in hopes of a reply from a member that has tried to fix this issue, or has expertise or additional info about these drives in other devices, and drive compatibilities, or if the boot loop usually means the HD or the motherboard SATA controller.
With the drive installed, the POST shows onscreen progress thru 6(?) icons steps, proceeding normally, until the last step, which appears to be mounting the drive, at which time it immediately restarts the boot process from cold start position -blank screen, POST UI appears, and begins loading again...
This is a Samsung SDR-5100N 16 camera DVR, security camera system.
Also, I forgot the leading question about forum and support categories:
"Is 'Smart-Home' the right place for this?"
(Is there even a current Samsung security camera product and/or category [for posts]?)
Thank you for your help!

Samsung_LaUKQmg Sorry for my confusion, are you also having trouble with your DVR? If this is regarding a HDD instead, you would need to create your own thread in our Computers section under Monitors and Memory for assistance.
This is my thread (my question here).
Do you also have a Samsung security camera system?
What model do you have?
I am happy to help you and share what I found out if you have the same thing.
What do you have?
I am a technician, and I unplugged the drive, and it operates normally without the drive installed (power off when taking drive in or out, ground yourself for static and not touch the pins and touch metal ground on unit and HD simultaneously).
Boots normal, gives 'no HD present error' and cameras and menus work normally then.
Take care, and post your question elsewhere, (as your own new post), IF it is not a DVR recorder with a WD drive.
Please let us know what you are talking about!
I will help you if I can. I am here seeking answers myself.

It could also be the format for the hard drive. New hard drives usually come without a partition. If the camera system doesn't see a readable partition on boot, it will try again.
Try plugging it up to a computer. It will probably say "this drive needs to be formatted". Do that, or format it within your OS. And try again. Sorry. Not sure what that system is able to read. I have no idea what type of format, I'm just pretty sure it's not formatted.
Thank you Daniel;
But the drive was original one, installed in the security system.
It crashed and now stuck in a boot loop.
It is either the system motherboard, or the harddrive (or conceivably both).
I don't have any computer that supports this kind of drive, (and the connector).
I was hesitant to try hot-plugging it.
I am trying to remember now if I tried that.
The format menu is accessible on the system only when the HD is unplugged.
It is a motherboard PC connector (CF?), not a cable.
(I think I tried hot-plugging it, IIRC, nothing to loose, and it began boot-loop again...)
Mr K L
I thought you were talking about a replacement. Not the original. If the original crashed, it possibly rendered the partition unrecognizable. And would throw an error when it tried to boot.
You said it boots fine without it. What about this - When you unplug it, turn on the system, let it get to its idle, then plug it in, does the system even scan for it? It might(translate to "it will hopefully") give options to try to fix it itself. Another option would be to take it to geek squad for a format.
Another option, like Cole said above, you might have luck posting in the computer section in the memory sub. If the issue here was the controller, it usually throws something, regardless of a drive being attached or not. I think the issue here is the drive though.
Try things that were mentioned and try to play with it, I'll check the memory forum for any additions there, and keep coming back here in case someone says something that makes me eureka.
Edit: I also tried looking into the system itself, but can find nothing about the HD, only that its 1Tb. But another option that I thought of was customer support. 1-877-213-1222 is allegedly the number for the security camera specialists, but that came from the Samsung website. The numbers get switched up fairly often. If you have an issue, try calling 1800SAMSUNG. They should be able to get you to where you need to be.
Thank you for the help!
I hesitated to write the whole story (in my initial post); I have done that before with bad results (eg.no results) on other forums.
I think people don't read if its too wordy or hard to follow?...
It is a Samsung 16 camera DVR security system; discontinued AFAIK; and now unsupported*.
It uses USB mouse (2 port USB front panel) and the camera monitor on screen UI menus to navigate (along with the camera feeds showing); and no other input method (AFAIK);
and NO master reset button! inside or out, no internal jumpers for setup modes, bios, etc...
Dedicated motherboard and bios. (I believe there was flash bios update provision built-in, via menu).
First condition; as 'arrived';
Boot-loop, resets, blank screen, delay, few moments the splash screen, then POST appears (no cameras show yet IIRC), it goes through 6 Icons a few seconds each, rom tests etc, each get a green checkmark or something.
Last one is the HD labeled Rec, and hits that one instantly kills the system and goes to restart, blank screen, (normal) delay then reboot process, splash screen, etc...
After few voltage and connection tests, (and lots of trying, disconnecting cameras, camera PS, etc); I tried unplugging the HD:
NOW, system boots normal, gets to the Rec last POST step, throws a 'HD not detected' error, and proceeds to finish POST, and put camera views up on monitor!
At this point, the full user UI menu is accessible by mouse, password access, navigate menus, format menu is there (FWIW), etc.
I could find no helpful choices for diagnosis purposes...
Another words, system works normally with HD out, but of course it can't record. And cannot format the HD with the HD disconnected, and cannot get TO the format menu with the HD connected; catch 22.
This does NOT exclude the possibility of a bad SATA controller circuit on the MB...
But I am thinking the HD most suspect.
I can not be sure I tried this (I looked at lots of things that night):
Booted up without HD installed, waited until POST finished, and flagged missing HD error, and then started normal camera operation, and user UI mouse navigation menu.
Then inserted HD; screen goes blank, and boot-loop resumes...
Again, I am not sure I did this, I was hesitant as it can be bad for a HD if it is otherwise OK.
I think I asked owner for permission and did this IIRC. (friend of a friend's system). Not much to loose trying this.
I did lots of tests with blank screens, and with or without cameras, with or without aux camera PS, alternate wall outlets (Samsung tech had me doing a lot of tedious (and unnecessary) tests and run power to another outlets, and another monitor, unplug for 2 min., etc, so I lost track of if I tried the hot-plug HD test.
*the moderator SamsungCole made 2 remarks:
[and thanks again for his/her help]
One was that 'most' Samsung teams no longer support this item ("most" - an odd choice of words, makes me wonder if there is some hope).
The other was directed at the person who hijacked my thread, not me, and instructed him to post in computer memory if his was NOT a DVR, as this thread concerns.
Also, your phone number referral is already in my notes (1-877-213-1222); THANKS!
It is one of MANY leads (mostly bad) given to me by Samsung chat and phone support from Asia.
They are on my to-do list, as were closed for the holidays last week.
1800SAMSUNG was of no help IIRC.
Also, the Samsung (Asain) chat referred (they provided the link) Samsung support pages do NOT accept this model number as a valid number!
I have tried maybe 3 phone calls, and 6 chats now...
Thank You Daniel!
