Paragon reports Invalid file system and disc not seen by windows 7

[pgsibson]

Hi
In rebuilding my system I have inadvertently caused a fault. I have a separate internal hard drive that contains logical partitions for data and photographs. somehow in rearranging things I now have a disc that if connected causes windows 7 not to boot and if not connected windows boots normally.
Examining the drive with Paragon recovery media shows the disc and the extended partition and the three logical partitions. The logical partitions are shown with partition id of 0x07 which I think is NTFS, fine but the file system is marked as invalid. I cannot attempt to do anything with the individual partitions, all greyed, out and I am afraid to allow Paragon to fix any BCD or other partition info in case I make it worse.

Has anybody had any experience of this and a fix?
Regards

I am using the recovery software so cannot grab and keep a screenshot

HI
This drive is a 3Tb WD green drive and the Paragon software is 2010, I think, I am not at home at the moment to check.

Hi

You need a later version of Paragon to work with 3Tb drives.
Was the drive supported by the motherboard or did you need to run the WD install utility to set the drive up first time.
3TB drives present all sorts of challenges, it helps if the motherboard bios supports 3tb drives and the OS as well if either don't there could be a problem.
Is the drive in the Bios detected as 2.74TB or about 800gb ?
Have you updated the Service packs on windows 7 ?
Are you running Paragon from windows , Linux boot version or windows PE boot version ?

Thanks

Just a friendly note.
This is a home built, Right? You are using a very large HDD, a 3 TB drive. As you know, problems people have using such large drives with Window 7 have been widely documented. A lot.
Here are my personal observations.
1. The OP could abandon the large drive and net the system up and running with a smaller drive. Most likely the performance would be as good, or even better.
2. The OP could partition the drive as a smaller drive and forget about  using the extra space. Again, the performance would be about the same.

Just  my observations.
