M..N 0 Posted December 15, 2014 Hi, I have a Qvis ATL400 DVR and am experiencing a problem with the HDD. The hard drive seems to making noises such as clicking and stuttering. I have a feeling the hdd is failing even though the system reports the HDD status as normal. Now my question is whether replacing the HDD will wipe the CCTV os, or is that stored on a separate drive. Further would it be as simple as popping in a new HDD and formatting it to the correct format. Share this post Link to post Share on other sites

M..N 0 Posted December 16, 2014 Hi. Yes you can just change hard drive out with no loss of OS Replace with new HD and it will format on first reboot Thank you, thats good to hear. Out of curiosity where is the os stored, I opened up the dvr and could on see one HDD, so unless the os is stored on the motherboard itself I'm not sure where else it would be. Further I'm thinking of installing WD Red HDD as these are meant to be used 24/7 would that be compatible with this DVR? Share this post Link to post Share on other sites

TechnicalTony 0 Posted December 17, 2014 If it's an ATL should be a WD green or purple. We use those on all our DVR's now Share this post Link to post Share on other sites
