So...I have a segate backup plus Portable Drive which has not been working since the month of October,2020. It doesn't show up in this pc...even not in the disk management section (but it showed up in disk and drivers, that's why i kept trying). I have tried different ports and cables. But it doesn't work at all...but today i tried disabling the device....and then re-enabling it again...and luckily it showed up on the disk management section too ....as a unallocated disk...i tried to allocate the drive but it wasn't possible... options weren't available...and a red mark is appearing in the section......but when i removed it again then it is gone again from the disk management. (Btw the light is not blinking but i can hear the sound of spinning and some clicking sound). Please help me with this...
