I've been using the Win 7 RC for quite a while now, and really have enjoyed it. Ordered a couple copies of the Windows 7 Home Premium Upgrade for my wife and I. Got her PC all updated no hitch. Unfortunately, I've been fighting the process on my system all night long. It's just been one thing after another. Apparently the Upgrade disk will tell you your CD-Key is invalid if you don't already have Windows XP or Windows Vista installed before you 'upgrade'. Anyhow, I finally got everything sorted out. However, I'm extremely frustrated right now by something Windows 7 did without my approval. In order to get Windows to boot properly, I had to disconnect my additional SATA drives so the boot record would write properly, and therefore Windows would load after install. Apparently, Win 7 decided however to take over the lone IDE hard drive I had not disconnected. Unfortunately for me, it took that drive which was LITERALLY FULL of videos and family photos and other stuff I had used it to store, and created a partition in it. Yeah, Win 7 decided apparently to destroy all of that data to create a 100MB partition so it can have it's own "Recovery" data in case I have a problem later. What the heck is with this?! I've literally lost hundreds of photos, videos, and other data that absolutely CANNOT be replaced. This WAS my backup drive to keep all these files safe until I reinstalled Windows 7, and now Microsoft has destroyed all my data. As it sits now, this drive has two partitions. One of which is 100MB (Recovery) and one is 189GB (Unallocated and has no drive letter, and Windows won't let me assign one). I read something elsewhere which indicated that Windows seems to mess up the zoning of data on the drive when it does this, and that a simple format might actually destroy the boot record on this drive. Is there ANY possible way to recover any of the lost data?!?
