Hi I am having a problem right now with the files that they are saved on (They are stored in a Superdisk) and my drive is messed from what I have read there is an allignment problem with superdisks and in any event I am currently unable to get at the files (to even see how far back I do go) I have ordered there allignement disk but have not recieved it yet (also have not been billed which is not a good sign) I will give it another week or so before I call Imation and find out what is up with the order. as soon as I can access the files I will email you what I have. I am sorry for the convoluted answer to this but as I have found out all backup methods have there own inherent problems.
