On my XP box I have used Keriver to image for several years. Always worked flawlessly. Got me a Win7 box. LOVE that OS now. Tried Keriver on it. It flubbed restore. Screwed up the whole system drive, MBR to boot -- er, NOT to boot. Smelly cyberfart. Had to get my tech to fix it. Sent Keriver up the river. Bah! Imaging is a key factor in enabling my minimalist security set-up. So I began a 2-week intensive search for replacement imager. Using Shadow Defender, I tried Acronis, Macrium, R-drive Image, AOMEI, Drive Snapshot (only app where support didn't answer my queries), & O&O. It was fun but tiring doing all these trials. The main factors I was seeking were: 1- an imager that walks me through everything with crystal-clear wizards & check boxes. Hopefully NO blanks or boxes requiring me to fill them in. GOAL: I never have to read their instructions or help files. To wit: I was seeking an imager designed by Phd's for execution by 5th graders. 2- an imager that does NOT offer a lot of tweaks, options, skins, eyecandy, & utilities not directly related to imaging. 3- an imager whose support team replies quickly & clearly with minimal technical jargon & acronyms. The one that best met my goals in Shadow Defender mode was AOMEI. So I ran it live today (not in ShadowDefender's protected mode) -- used it to create booter, WinPE & AOMEI on my 2tb external hard drive. Used it to image disk 0 onto the external hard drive. Then booted to the external hard drive, said a prayer, & did a restore to drive 0 on my sweet Dell laptop. I hated to do that because that laptop is running sooo smooth & does everything I want it to do. But I HAD to know if AOMEI could be relied on, so I rolled the dice & did a restore. Shazam! It is perfectamente for my needs! Your mileage may differ.
