To my surprise when attempting to reformat a ADFS HardDrive !HForm 2.56 October ROOL release failed to do anything reporting an Error 'SWI not known at Line 110' I tried a backup copy with exactly same result. Anybody else tried this? I haven't had to format a H/D for years! However, reverting to the older version 2.54 - that worked perfectly! Is this an side effect of (Flashed in) RO 5.14 a hidden bug revealed? I find 5.14 to be absolutely excellent in every other way, the week I have been using it.
