HFS+ USB HDD backup device indows 7

Have two different external hard drives and wondering if either/both are suitable as Back Up and Restore Devices For Windows 7..

1) I have a Western Digital 750GB passport usb portable hard drive.
It is formatted HFS+ with MacDrive...

*1A) Possible/definite issues using as Back Up Device when need to restore/repair, ect on Windows 7?
1B) Will be installing windows 7 on second PC soon. Can HFS+ drive be used to Install windows 7 Image/clone (from Laptop) on new fresh Hard Drive?
---
2) Second external is a network device (not quite a NAS?, but connected to Ethernet LAN port on my router) it is a Segate GoFlex Network Version...

2A) Are there issues with using external network HDD as a back up device?
2B) Possible/Likely issues accessing network device if using to restore back up on crashed/damaged or fresh Windows 7 OS and/or program/user data
*** meaning will network attached drives not even be accessible if windows is screwed up or during install on fresh HDD?

Not priority, but if anyone knows off top of head...
Segate goflex network external drive has a usb connection port on back...
I know segate sells 'usb adapters/cable KIT' for some stupid cost.
*Can I connect the external drive to my pc with a normal USB cable?
If so, what type of ends exactly? (ie Male to micro/"B", whatever?)?

Thanks again everybody for support!

I'll try to answer part of your questions. Windows will not install from a HSF+. As far as I know it has to be FAT or NFTS. Mac can read NFTS but not write to it, but windows cannot read HSF+.
As far as the Network drive. ASFIK, it depends on which version of windows 7 you get. Home premium will not back up to a network. Professional and Ultimate will. Home Premium will back up to USB or eSATA. As far as the adapter for the Seagate GoFlex, check Amazon, they sell them much cheaper than Seagate.

Thank you sir! Hey, I dig your signature graphic - that's sweet!
