X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sun, 07 Jun 2009 09:43:42 -0000 Hello list, Can anyone please recommend to me a program that will stress-test a disk? If it matters, two are connected by firewire, another via usb. Filesystem is ufs. I think I have a disk that might be about to fail, but it only sometimes errors when under stress. I need to see if it was a fluke or to really make it fail, so that I can get rid of it. thanks -- John
