USB disk not always mounted

[giovilux]

Hi,

I'm experiencing strange behaviours with an external USB attached disk.
1. powering on the rpi with the disk attached in library there is a blank page
2.disconnect and re-connect the disk to the usb library now shows that there is an usb source
3.once I can see the usb source I can sometime see only one of the 2 directories in the disk

Thanks
giovanni

one more thing,
once I add something to the queue the library may disappear without any reason

Thanks

Thanks Janui,
the disk has it's own power supplier.
I've done some more tests and I suspect the problem is in the sd card. I've flashed it several times without results.
I've flashed a brand new card and this works in both rpi that I have. I will now get a new cart and try again.

I think the problem is in how the sd card has been flashed.
I reflashed the card removing all partitions from linux, then I initialised it in widows disk utility and eventually fleshed the disk image with rufus.
It works now (cross the fingers).
