Win7 deletes non-drive partitions created by XP?

I am upgrading an old Asus M2NE from XP SP2 to Win7 Pro. I currently have 6 SATA2 drives on the old MB:

SATA1: SSD Sata2 (C drive)
SATA2-6: all seagate barracuda's in different sizes.

I also have an external JBOD NAS box with 2 more barracuda platters and a couple of old 500GB Seagate USB drives.

The plan is to replace the old SSD (128GB) with a new WD Black Caviar 1TB and use this as the new C drive with a clean install of Win7 Pro.

While I was browsing online I saw a wikipedia page about migrating to Win7 that said something about certain types of drive partitions created under XP that could be "delete without warning" when you migrate to Win7.

Of course I did not bookmark the page and now cannot find it again. This has me a bit freaked out since I have about 8TB of data, most of which is not backed up. I'm a JBOD fan and when a drive starts acting flaky, I buy a replacement and transfer everything over. Sounds goofy, but I rarely lose data.

When I've added a new drive under XP, I usually format at as a single primary partition. The only exception is that one of the barracuda's on the MB is a 3TB drive, and to get XP to recognize it I had to use Seagate's partition tool.

Has anyone heard of any conditions that would cause Win7 to delete a partition on a non-boot drive that was created by XP SP2?

Thanks for any help,

-Dan

type diskmgmt.msc in to run. you will see your drive then reformat it/partition it to what you want. This is one of the awkward things about 7 and up. May or may not need to be formatted into NTFS as fat 32 only supports file sizes around 1gb.

OK. Maybe I was not clear. I have a bunch of drives that I formatted under XP. I think they are all NTFS. They contain about 8TB of data that I currently cannot backup. I am trying to KEEP the drives and data when I switch over to Win7, and NOT reformat the drives and LOSE the data.
