iPad — the first glitch

April 14, 2010 By JimK 5 Comments

I took my new iPad to a meeting yesterday. An issue came up that made me want to look at an attachment to an old email. I whipped out the iPad and found the right folder, but the e-mail wasn’t there. In fact, I could find none of my old emails. When I got home,… [Read More]

I formatted the drive as an 8 GB single partition, created the top level directories, and set Vice Versa to work backing up the server on line files. After about two days, all the data had been transferred,… [Read More]
