Sandisk Cruzer Blade 8Gb not recognized when creating bootable disk

Another update and another clue as to the cause of the issue.

The Sandisk flash drives that can be ‘seen’ by the ISO burning tools are seen as being “Removable” in Disk Manager. The drive that doesn’t work in the ISO burning tools appears in Disk Manager as “Basic”, in other words, it’s not seen as a removable drive.

I tried deleting the partition and recreating it through Disk Manager but that didn’t make any difference.

So now the queston becomes:

How do I change the bit set on the Sandisk Cruzer Blade such that it can be recognised as a removable drive?

Thanks in advance.
