Windows 7 Corrupts Floppy Disk

I have purchased and installed Win7 on a New (2 months old) PC that has a New floppy drive. The first time I used the drive I inserted a disk and opened it up to see what was on it. Explorer showed files and allowed me to open one for viewing. I then deleted all files from the disk and attempted to copy other files to the disk at which time I got a device not readable/disk not formatted. I attempted to format the disk numerous times with no luck. I used another PC (WinXP) to check/format the disk and again put the disk into the Win7 PC and opened it - showed disk empty (Good). I then copied some files to the disk, they did copy this time, then closed all windows and reopened explorer to the F. Drv again at which time I could See and Open the files. HERE'S WHERE THINGS GET FUNKY. I close explorer window, remove the disk and reinstalled the disk, open explorer to F. Drv and now the disk is EMPTY. When I try to again copy files to the disk I get the disk not formatted - but it will not format the disk and keeps giving a bad media message (I've tried 15 disks). I figured it was the drive (HW) even though it's new so I obtained another New drive and it did the same thing. I changed cables 3 times (one cable is new) - NO CHANGE. I tried an old but good drive - NO CHANGE.

Each time I try to read a floppy disk and then try to read the same disk on my WinXP PC I'm told the disk is not formatted/corrupted file system. The disk(s) are good and work as advertised in the XP machine but not with Win7. Kicker - my USB floppy drive works very well with Win7 and no issues.
