By all means, install ext4 to new disk, and we'll investigate old ones
when you can.
I need to see output of "mount -v whateveryoudo" on the external reiser
disk, and "dmesg" NEW output when you do that. Then output of "mount
-v", and try to write a file, with dmesg output.
We need to see facts, not your interpretation of them, so that we can
add eyes over your shoulder.

I realise that BtrFS can, when individually mounted on partitions, shrink and grow
like ReiserFS, but that's not the way it was designed. certainly Ext4 isn't a
real B-Tree file system like ReiserFS & BtrFS. lets face it, Ext4 still harks
back to the original V6/V7 file system where you pre-allocated a certain number of
indeed in i-node space on the drive partition at MKFS time and that was that.
Yes the Ext4 space allocation and management might be more efficient because it is
B-tree managed, but it doesn't have the "unbound" aspect of ReiserFS, BtrFS
couple of other of the REAL B-Tree file systems.
The other thing I don't like about Ext4 (and that goes for other file systems too)
are all the MKFS and mount time options. A file system should be 'general purpose
unless otherwise clearly stated.
Now I'll grant you that some types of storage can be specific.
The "MyMovies" tree should be like that, all big files.
But photos? The problem there is that while the RAW and other image files ARE
large the 'sidecar' or edit log files are not, they are just text file.
Talking of text files, there's also 'book', be they Guttenberg or e-books.
variable in size but not too large.
Yes, all of these can be categorized and isolated on the overall FS and the
underlying FS optimized', whatever that my mean. But perhaps that's not really
relevant with a good B-Tree FS. Which Ext4 is NOT.
Why is it not? Well read the man page.

Really: BtrFS is a massive step in the direction of the old IBM 1960s model file
systems and OS support.
