And this thing is advertised for its reliability...
Today upon starting Windows a notification appeared
"Found new hardware: USB Composite Device" and then nothing... (in device manager and disk management as well).
I shut my pc down and made a second attempt after an hour.
This time the notification stated "found disk drive", I went to Disk management to reformat it to NTFS, made it open the drive folder to see what's there (there were some WD programs - autobackup etc.).
Then suddently my Windows restarted and the WD drive shut down on itself, and, again, it's not recognised any more.
I can, of course, repeat the procedure, but I 'd like to know what caused my Windows to restart. Will it happen again, if I continue struggling with this device? Why is Windows recognizing it only from time to time?
