No, if I recall the details correctly, a disk formatted NTFS in NT SP3 or later could not be read by by NT until you upgraded to at least SP3.

I could be remembering wrong, but I spent several hours trying to understand what went wrong and why I could suddenly no longer read the disk & worried that I'd just lost several years of data. Ironically this disk also had the service pack installers on it. The whole point was to do an offline install+patch.

After I finally got the disk to be read, I did some experimenting and realized Microsoft did something screwy in SP3 to NTFS. Disks formatted *before* installing SP3 were fine - could be read pre and post SP3. Disks formatted on/after SP3 could not be read by a pre-sp3 system.

I've personally run into this and have spent hours asking myself w.t.f.? I can't read this NTFS disk after a reinstall (but before applying service packs)?
