Replacing an existing hard drive

PC drives can also tend to try to do error correction on the typically glitchy data streams from live TV broadcasts, and some camera streams, which is not needed and typically not done with surveillance and CE drives. :eek: Note the Toshiba drive linked to is one for such video usage.

Uh? Drives that do error correction on the streams from TV broadcasts? What does that even mean?

We can argue whether one drive is better than another in terms of performance, but that's about it, nothing 'really really complicated', I wouldn't make it sound more difficult than it actually is.
We have lots of desktop computers that have been running 24/7 for the past 7 years or so (company policy :shhh: ), hard drives failed? 2 or 3.

Desktop computer drives aren’t writing continuously, that’s why Western Digital (and others) make specific drives for CCTV type applications. There’s not much difference in price, so why suggest a lower spec drive is suitable?

Who suggested anything? OP asked if that drive would be compatible, and I replied "Yes it is".
Then someone jumped in saying that he should be getting advice on other forums, that replacing drives in DVRs is complicated stuff, etc etc.
We can argue whether one drive is more suitable than another, but I repeat: there is nothing complicated in replacing a 3.5" SATA drive.
If you (God forbid!) choose a drive that is not the best of the best, worst thing that can happen is that you will have to replace it in a few years' time when (and if) it fails.

I've seen more 'really really complicated' stuff.

EDIT: you will be surprised to know that 24/7 usage on DVRa is actually less 'demanding' than PC usage, simply because the vast majority of DVR writes are sequential, so there is little movement of the HDD head. On computers, files are stored all over the place, and this requires more mechanical movement causing more stress to the drive.

FWIW devices can be fussy - I replaced the hard disk on my humax PVR a while back, and it required that the disk spin up within a certain time - if it was too slow, it failed to detect it. So only some models of disk were supported.

that

I would buy this drive through Amazon, because you can return it.

If you look at the specs is mentions "Advanced Format (AF) 512e Sector Length". Personally thought it would be a linux format.

Won't the HDD in the current PVR have a manufacturer-specific OS upon it, which the OP won't be able to install?

frugal - thanks a lot for posting the picture here


everywhere and rodders - apologies, the make is Floureon A6808NHS-UK


mole rat - I will basically be keeping the HD footage in case I need it in the future, if I do I will reconnect it to the device and then pull off what I need via USB. Thanks for the advice on looking u pspecific forums, I will search for that.


Rodders - thanks for that, now I know to look for a specific HD. Would this be ok: .ebay.co.uk/itm/Seagate-Skyhawk-1TB-4TB-Surveillance-CCTV-NVR-DVR-3-5-SATA-Hard-Drive/162836804186?epid=2059561241&hash=item25e9d4725a:m:m8CfSLNp-iSACOdLVbgsZ3w:rk:4:pf:0
