I'm running Windows 7 Home Premium SP1 64 bit on an Intel HP Pavilion dv6. I have a PNY 16 GB USB drive that is now useless because it has somehow become "read only". Did this happen with bitlocker? I did not knowingly run bitlocker, and when I type it in the serch bar it doesn't find it, so my version may not even have bitlocker?
I've read all the other similar questions and tried what they said. So far I have added: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies registry key and the DWORD WriteProtect with a value of 0 and rebooted. I have set permissions to full control for this disk, I have used DISKPART to Clear the readonly Attribute, then rebooted but nothing has worked. When I use DISKPART to list the attributes for this disk, it says:
Current Read-Only State : YES
Read-Only : NO
So I guess the Read-Only attribute was cleared, but it is still in a read-only state. How do I change the state? How do I prevent this from happening again?
Someone said they took the disk offline and then back online and that cleared the read-only state, but when I tried to take it offline, I get a virtual disk service error: "The operation is not supported on removble media."
Any help would be greatly appreciated.
