AVTECH and usb external hard disk

[damai7788 0]

Hello All,

I'm using AVTECH KPD 679/67x.

Trying to do direct backup from the usb port of the DVR.

 

If I plug an USB Flash Disk 4 GB into the DVR, the DVR can recognize the UFD and can backup data into the UFD.

 

But when I plug an external USB Hard Disk, either 2.5 inch or 3.5 inch, both external USB is not recognized by the DVR. So I cannot backup data into the external HD.

 

What is the problem?

Anybody success to do direct backup to USB External HDD?

Is there any compatibility problem?

Or related to the file system/FAT32/NTFS?

 

Thanks.

Hi damai,

 

The hdd should be formatted with FAT32. And the hard disk has to be one supported model.
