Springers 0 Posted October 9, 2010 Hi, I have a Ray Sharp H264 1TB DVR and after a power cut i can not get the unit to recognise the hard drive. I have formatted the drive but it still says the hard drive is unformatted. I have tried contacting the manufacturer but all the emails get bounced back. Any help would be greatly apprciated.

sant12345 0 Posted October 10, 2010 i had similar problem some time before from a unit from taiwan. I contacted manufacturers and they resolved this issue. The problem was detecting external device like monitor after abnormal shutdown. ask for latest firmware from supplier or try download from their website.

Springers 0 Posted October 10, 2010 Thanks for the info but all the emails to the manufacturer keep bouncing back and there are no firmware downloads on their site. At a bit of a loss really as with no hard drive in it works fine just won't recognise it when it's installed. Share this post Link to post Share on other sites
tesc_cctvpro 0 Posted October 20, 2010 Have you tried another hard drive?. Hard drives are very sensitive to irregular power issues --- the key is that this occurred after a power cut! Share this post Link to post Share on other sites
singh_city 0 Posted February 12, 2011 Hi I have the same unit its a ray sharp 4 channel h264 dvr with a samsung 1TB hdd. The problem I have is that the hdd keeps coming up unformatted and shows 0hr useable. I have tried it with a 160gb samsung hdd and it seems to work fine, but the other problem is the 1TB hdd seems to format and work fine when connected to a PC. How can I resolve this issue and get it up and running asap. Share this post Link to post Share on other sites
Springers 0 Posted February 12, 2011 Hi. I have had this problem for ages and the way to resolve it is as follows: power the unit off. Remove the psu connector out the back. Turn the unit on with the psu disconnected. Turn it off and replace the psu connector. Turn the unit back on and the HDD should now work. This process clears the flash (I think) and the HDD starts to work. I think the flash gets corrupted during power outages or spikes and stops the unit finding the HDD. Hope this works, let me know how u get on. Cheers Springers Share this post Link to post Share on other sites
SkySystem 0 Posted February 15, 2011 Have you try to factory restore default and try another HDD? Share this post Link to post Share on other sites
