Windows 7 New hard drive installed with windows 7.... recovery drive full

Probably the first thing I would do is give Dell a call and question them as to what's going on. Can you screen shot the disk management console so we can see exactly what you're talking about (see attachment). I'm firstly kinda suprised that the Dell Recovery Partition is getting Drive D as a partition assignment, since I would have generally assumed that your DVD/CD player would have that letter. Can you examine the contents of the recovery patition, do you see files that you have saved on there, usually these partitions are a fixed size and are often nearly full by default, since they are only suppose to contain the recovery image and some files to support the restore process executeable. Let us know

Here are the screen shots

Wow, looks like your suspicions are correct. I would definitely contact Dell and see if they can explain, what's going on, since the programs directory and the Windows directory, show a last modified date of the 25th, I can't say for sure if the guy who installed your new hard drive put them there or if they are a product of some recent use. What's on the C:\ drive what do the dates look like on there, are the dates more in keeping with recent activity. When you install a new program can you see the install path and does it reflect an install aimed at the C or D drive?
