Hi all. Stuck with an issue on 2 Mini NVR's N6200-4E and N6200-8E
Both units have now got the same problems.
After a reboot the mouse cursor is stuck in the top left corner (2)
Usb supplies power to ext HD but doesn't recognize it (2)

I have tried a few searches on here and found a couple of posts similar but no real clues as to the proceess to fix.
Both units still show ALL cameras when connected to a screen but there is no recording happening or menu access (mouse issue)

Some valid pointers would be most appreciated
Thanks Bazzle

Check my last post which I must give credit to at least 2 people in here (alanduy1 & tomcctv):
Bad Board!
Do you have any heat sink inside the unit?
Any fan?

Thanks for the reply.
Sadly I dont think it is an overheating issue.
They stopped working from a cold boot.
Both have the same usb issue.
It leads me to think there is a software or hardware issue as all other camera viewing and network functions work.

I probably need a way to RESET both units to see if the comm link picks up the usb connection .

EDIT:

I have found a similar issue in the Mini DVR Thread so I have cross posted there as well,on page 85...

Reformat Hard Drive?
Your CPU apparently doesn't like what is going on and so your OSD is turning off (freezing: software/memory bad).
A simple remove/reinsert on mouse should indicate if the "mouse was lost". In that case, you need to install a feline to catch it. :mrgreen:
If that is the case, I would recommend installing a Margay; not only will it go after your "mouses", but also rats, scorpions, bats, roaches, etc...

Worst case, your CPU is already fried.

Plug hard drive directly to Windoze® and see if it is recognized.

Have you tried with Hard Drive disconnected???

Every thing works fine other than the usb's. HArd drives (tried a couple all wotk OK away from unit.
The comm to the usb's has been compromised.
The link on the other posts shows a chip that "may" be the culprit. The NVR still works and shows all connected cameras. I just cant record anymore as HD plugs into usb.

Could you post the link with the picture of the chip?
I didn't see it.

USB Hard Drives are very unreliable on Windoze.
Are they formatted to NTFS?

Next to last post down this page .

I dont thinks its a HD issue. Same one(s) work OK on another unit the same.
USB issue seems to be a known one. Mouse not working on USB either, tried 3 known ones that worked before.

Glad you got it working!

I do see the pictures, now - I guess I thought the post had ended at the extra large Ad and didn't scroll past it.

Could you post the numbers on "the chip"?

Really got my curiosity going, now!
:o
