We use a PA-200 in one of our offices (we also use firewalls by other vendors :) ) and got a notice regarding a "device replacement program" initiated by Palo Alto Networks for some PA-200 with a problematic HD.
Based on Indeni Insight data, it seems that less than 1% of devices out there are PA-200. Not sure what percentage are actually affected by the issue (not all PA-200's are).

Anyone affected by this?
