Dedicated Micros DS2 DVTR DVR Hard Disk Upgrade

This week I’ve had another pair of DVR’s on the bench without Hard Disks (Well, one with dead Hard disks, but that’s neither here nor there). I obviously had a pair of IDE drives knocking round from the DVTX from last month, so a quick reformat with the formatting utility and a download of the firmware zip file (copy the contents of the zip file into the drive when done) showed them both to be fully working once new PSU’s were procured.

I took a chance on some different IDE to SATA adapters this time, after the listing proclaimed their compatability with DVR’s, and to my surprise, they both work fine!

The link is here on eBay and they’re £14 each and they’re made by Avtech, which is a good deal cheaper than the StarTech ones which I can’t find anywhere currently. They arrived very quickly though compared to the others.

So it looks like both DVTX, DVTU and DVTR DS2’s are happy with IDE > SATA adapters.

DVTU and DVTX’s are both happy with Samsung 1TB Drives with 32Mb Cache (eBuyer Quickfind 173804).

DVTR units can cope with a Seagate 500GB Drive with 16Mb Cache (eBuyer QuickFind 272944), but this appears to be the largest they support. You could probably get 1TB of disk out of a pair of them, but I’ll need to confirm that by adding another to my next order.

    Our Digital Sprite2 c: drive failed today. I went and looked into replacing the hard drive and found in the read me file that you have to load the correct software to the unit or it will damage it and only the manufacturer can fix it. When the unit was installed the software version was not documented. Is there anyway to figure out what model it is other then looking at it while it is online?


  • Victor Presher says:

    If I understand your meaning then it does not matter what model number the unit was. I can load any of the three versions on it and it will be ok. The three versions I am referring to are DS2-DTVR, DS2-DVTU and DS2-DVTX.

  • No, you need to load the software for the right unit. The versions of the software vary from unit to unit.
    To work out which is which, open it up and there will be a white sticker on one of the chips that will say DVTR or DVTU or DVTX.
    You can tell a DVTR from a DVTU or DVTX by the BNC input/outputs – if they’re all in a straight line, then it’s a DVTR, if there are 10 BNC’s on the right hand side of the unit, and another set on the left hand side (slightly raised compared to the others) then you have a DVTU or DVTX. Also DVTR’s have hard disks to the left of the main board, DVTU’s and DVTX’s have the hard disks in front of the main board.

    Hi Alex,

    That is very useful information that you have provided. I wondered if you have in your knowlege the codes required to to format a new disk once it has been discovered.
    I have two new 320gb disks after using a third party fat 32 formatter I have inserted them and tried different jumper and cable combinations however the disks are not showing up have you any ideas?

    Many thanks

    Hi Alex,

    Thank you very much for that information. I have copied the firmware on the new disks as well as two smaller spare disks the result is the new disks are not seen at all in after the boot loader completes it’s tests.
    The spare disks however say that it is loading the application from the disk it then stays like that whilst a red led flashes continuesly on the front of the unit have you any ideas?

    Hi Alex,

    The model number is a DS2A DX16C DVTXV165.
    Disk type IDE originally two pairs of Maxtor 160gb replacement IDE 320gb western digital.
    On my previouse post I did not say that I was using an older 80gb maxtor drive that allowed me to get to the application loading message.

    I hope this information is helpful however if you require any further please let me know.

    Mank thanks

    Ive been reading this now I had the flashing red light so changed hard drives for 2 500gb hard drive was 320gb model ds2a. now had it running fine and now every day the red light starts flashing worked fine for 3 days. has a repaired psu as the capacitors had burned out. now i’ve tested hard drives and they are fine. tested the power pack pcu and voltages is good. so was thinking could it be something on the board as the 3 pin chip does get hot really hot and so does the capacitors. i have a cooling system inside. now I cannot keep changing hard drive when software says they are good. can any one help me figure this out thanks .

    Just ran across your blog. I purchased a DS2 off of e-bay yesterday for really cheap. The guy said it was working but we will see.

    I have experience with these at work as a manager but of course we contract out the install and maintenance on them so when they break and they have, we just have the tech come and he generally puts in a spare and sends ours out to be fixed.

    If the one I purchased isn’t functioning or has a bad hard drive for what I paid for it I’m not going to complain. He had it listed for $200 USD. I made a real low ball offer of $30 and he accepted it. So I can put some money into it if need be.

    Great blog and thanks for posting.

    Alex, I just purchased a DS2 DVTR off of an online auction site. I got it for next to nothing.
    When I boot it, it has an IDE test: Failed then the message “Halt at Bootloader”.

    I haven’t done anything to it yet, but does the IDE test failing mean the controller on the motherboard is bad or could it be the hard drive?

    Any help would be appreciated.

    Just a note for anyone that works on these all the time. I’ve replaced around 15 drives on these DM DS2 AD units. I pulled a good drive from a woking unit, cloned it to another new drive (don’t bother formatting the new drive…Acronis sector copies and uses origional drive formatting) …. I used a WD 1 TB blue 64 MB cache (approx $46 US) to clone it to using acronis disk director. It takes a few hours (approx 7) to clone them. The newly cloned drive is now my master. I use the new master to clone to the new WD drives, insert them into DM and just boot. After booting it will format the video area it needs and then run perfect. Use IDE to SATA adapters if you have older IDE DVRs.

    I have a different problem. I have 2 DM DVR’s. I have 25 cameras so I needed two DVR’s. (DVR1 – 16 port – DVR2 9 port)
    I cannot get the 9 camera DVR to work on a phone app called IP Cam Viewer. The TP-Link Router is set up to handle (Virtual Servers page is set up correctly) both DVR’s and the DVR settings are identical (except for DVR1 (16 port) is – port 8236 and DVR2 (9 port) is – port 8238 … The only difference I can see other than the internal IP addresses and the ports is: One DVR is a DVTX and the other is a DVTU. I do not know what the difference is between a DVTX & a DVTU unit. Could that be why one DVR works with the camera app and the other one doesn’t?
    I have a Static IP from Verizon. (for many years now)
    Both DVR’s work perfect both from my LAN & also WAN using Network Viewer
    DVR1 – version 3.1 (169) Net (DVTU) unit
    DVR2 – version 3.1 (169) Net (DVTX) unit
