How remove write protection from usb drive

#1
An external USB-connected HDD is write-protected after reformatting. How do I remove the write-protection?

I tried a tip I found on several sites where the suggested solution is to set the
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies
value to zero, but that didn't do it.

Any suggestions?

I'd first try the drive in another machine and with a different connecting lead to exclude the pc and the lead as possible causes.

Already did that but thanks Pat.

Yep, DiskPart did it. Thanks bassfisher, yet again.

I'll quote myself from elsewhere on the forum and say how sweet it is to belong to a community like this and get friendly, informed, knowledgeable answers to ones little queries. Love it.

When using the registry hack, you need to make sure you change the value on all "ControlSet" values, so if there is a ControlSet01, 02, etc, you need to change it on those as well and then reboot.

Yeah well, the funny thing is that before I got rid of the write-protection by way of DiskPart as per your suggestion, the StorageDevicePolicies value was set to zero...anyway the drive is OK on that count now.
