Partition sizes: Misreported and changing sizes (two separate issues)

OS: Win 7 Ultimate x64 SP1
AMD Athlon 64 x2
3 GB RAM

In another thread I wrote about how I managed to wipe out my hard drive while using a disk utility that told me my partition sizes were reported incorrectly. (Screen shot below)

I told the program to go ahead and "correct the error" which immediately killed everything. I did manage to recover my data partition and then did a fresh reinstall of Windows. However, I still get that "error message." It's not just Partition Doctor that reports it, Partition Master 8 also gives the same error.

So the question of the day is, why am I getting this error?

Next question is about changing partition sizes. I've used Partition Master for years to resize partitions but now not only am I getting these strange error messages but the software reports that it isn't compatible with Win 7. So what can I use to resize partitions. Symantec has no new versions of Partition Master.

I have C: and E: on one drive. C: is too big and E: is too small. In the past, I would have used Partiton Master to take the extra space from C: and give it to E: but can't do that now. Windows Disk Management tool will shrink C: but not give the space to E:

So the second question is, "What can I use to fiddle with my partition sizes without having to back up E:, delete it, resize C: and then recreate E: at the new size?

Personally, I'd recommend Partition Wizard as it is far more flexible and functional than Windows 7's disk management utility.

You need to download the PW ISO and burn it to a blank disc then boot into it to partition your hard drive.

When you're done just boot back into Windows.
