Filesystem for a Time Capsule

By RAW format I really meant just a bitmap, without compression.

Makes more sense to use a jpg and include documentation
on the compression in a plain text file in a separate file.

A BMP only has a short header followed by normally 3 bytes per pixel.

No compression is important.

Nope, all you need to do is document the compression.

Agreed, camera 'RAW' covers an enourmous range of non standards.

Yeah, you should have said BMP.

No, not Apple Time Machine, but an actual time capsule.
I have been asked to put together an external USB hard drive; format it
and put a bunch of pictures, videos - you name it on there.
It, along with other trinkets will be sealed in a container and buried.
At first I was thinking ext4 since it is non proprietary. Or ext2 for
the same reason and the fact it is non-journaling.
NTFS? Maybe but I don't know what form M$ will be in circa 2110.
Fat16/32 - out of the question since some files will be bigger than 4GB.
What about fat64/exFAT? Is there a utility to format a *hard drive* to
fat64?
I'm not even considering Apple's HFS+.

Since most of us (myself included) won't be around when this thing is
opened this is more of a thought exercise than actual task.

I suggest that no 100 year old drive will spin due to hardened or
oxidized bearing lube and heads bonding to platters. I have some 10 year
old IDE drives that need a bit of help to get spinning, I use the old
"flip" trick.

100 year old capacitors are another likely failure point, they dry out
over time.

If you want the future users to have fun playing then go ahead and use
any hardware & format you wish. If you really want to save the
information, print it on non-acid paper. Braille might also survive
well, in that case they will be able to read it even if our sun has shut
down.

Its unlikely to be none and easily fixed by using a
non hard drive anyway, in addition to the hard drive.

and heads bonding to platters.

That doesnt happen with modern drives that dont let the heads land on the platters anymore.

Doesnt meant that that will happen with all modern drives.

They dont all have electros and even electros dont dry out over time when not used.

And even if they do dry out, that doesnt necessarily stop the drive working.

Not viable for video.

Braille might also survive well,

Not viable for video or photos.

Fraid not.
