If the GZ-HD7 hard drive is Fat32, than that will explain the 3.5-4GB limit clips it creates (which is a pain!), and if it can be formatted to NTFS, than I expect the recording time can be larger?

I tried searching and couldnt find my answers, dont give me a hard time if its out there. Thanks!
The GZ-HD7 has a HDD format in FAT32.
The file size limit is 4Gb. If a recorded sequence is longer than 4Gb (= one shot of more than 18 minutes in Full HD or in HDV compatible mode), the first file is closed and a new one is created.
Note that there's no 'clever' thing regarding the closing of the GOP or the synchronization of the sound at the cut point between the 2 files: if you need to edit on PC a full complete sequence without having problem of image and/or sound at the cut point, the better way is to merge the 2 or more files in 1 full file with a dedicated software (or with DOS command: COPY /B FILE1 + FILE2 FULLFILE).

It's not possible to format the disk in NTFS: the firmware of the GZ-HD7 has no 'driver' to work with this format (that would require some extra royalties...).

The disk has a special tree of directories: don't format it from a PC. Instead, make a 'bit for bit ' copy on a bigger disk on PC (see 'Ghost' tool).

I don't know the physical interface type used by the GZ-HD7, but a 1.8" HDD with a higher capacity in the same type of interface could be surely put in place (and surely too, the JVC warranty would be lost...). Format the new 1.8" HDD in FAT32, copy the content of the removed HDD into it, or better, move back the 'bit to bit' image on the new disk, expand the partition size to the full capacity of the new HDD with a Disk tool software.

Some recent stats show that the actual SDD (without any moving part) have the same, or even worst, failure rate than the HDD. So that's not a good idea for the moment.
But in some months, when the SDD technology will be improved on the failure side, and when the price will drop too, it will become a good solution to replace the internal HDD by a SDD module.

Until this future date, the only advantage to use a SDD instead of the factory HDD, is to break the altitude limit: a HDD is limited to 10000f/3000m (yes, you must not use a HDD camera if you are fan of skydiving...).
