Windows 7: USB drives lose full disc sharing permissions after reboot

USB drives lose full disc sharing permissions after reboot

I'm running Win 7/64 Home Premium on my media PC with 7 USB drives, all connected via a powered hub.

Whenever I reboot (warm or cold), the sharing permissions are lost, generally to all, although every so often one of the WD drives will maintain it (the Seagate ones always lose them). I've tried using different ports to no avail. I've changed the properties of the drives so that I am the owner (as an Administrator). That doesn't help either.

I've read that Windows keeps a list of dynamic shares (or something like that) and that this behavior is by design as drives can be disconnected when the PC is not running. Is this true? I never had a problem with Vista, so this is definitely a Win 7 thing.

If anyone has a clue or can point me to a link for help, it would be much appreciated. Thanks.

Hello,

It could be that the devices are being re-labelled and given the incorrect letter when you turn the PC on. Can you try it with just one USB Device plugged in? Do you have the same problem?

Keep a note of what Drive letter is given to what device. Restart and see if any of them change.

Hi, Dave. Thanks but, unfortunately, that's not it. I assign specific drive letters to all my externals in Disc Management. So they always come up the same.

The only time they change is if I run Acronis TI outside of Windows to restore a partition. I guess that's because TI ignores the removable disc drives and assigns the letters sequentially.

Thanks, I appreciate the link, but I already saw that a couple of months ago when I Googled (didn't realize it was from this forum). I believe that's where I got the notion about dynamic share list.

I don't know why Win7 has decided it's better this way; certainly never had any problems in Vista. And, if the drive(s) isn't available upon reboot, why can't it be treated like a disconnected network drive that's mapped. I'm also surprised I haven't come across more complaints/frustration about this. Ah well ...

Thanks anyway. I'm glad I found this forum.
