Years ago, when floppy discs were the norm, I was used to having to flip the write protect switch (or cover over the notch on older discs) but I was a little surprised today when I couldn’t write to my USB removable hard drive because Windows 7 told me that the media was write protected. I tried adjusting the properties on folders but the actual disk was showing as write protected – very strange.
I still don’t know why this occurred but this was the disk that I use to keep personal items separate from work on my company-supplied notebook, which runs BeCrypt DiskProtect – and I suspect DiskProtect may be part of the issue. Nevertheless, I did find an apparant solution, courtesy of a post at Windows Seven Forums that refers to a post on the T3chworks site.
diskpart.exe from an elevated command prompt (
cmd.exe), I was able to issue a few commands to remove the readonly attribute on the media and write files to it again:
select volume volumenumber
attributes disk clear readonly
Only time will tell if this is a permanent fix (the post also talks of modifying a registry entry at HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\StorageDevicePolicies\WriteProtect but that’s not present on my system) but I’ve never seen this before, and it seems to have done the trick for the time being.
