Terabyte and TeraStation

When talking about storage capacity, the correct term is Terabyte, with a single R. The incorrect form Terrabyte has to have something with ground and soil, as in terra firma.

Along the same tune, the Buffalo product is called TeraStation, meaning a "station where terabyte stops", not Terrastation (which could probably mean a spaceport or subway station, or some other ground facility).

This is specifically annoying when folks in data recovery mix up these two. They are, like, supposed to know better.

NTFS Deduplication

If you use NTFS Deduplication feature on Windows 8 Server (Windows 2012 build 8400), the deduplicated data is not recoverable by regular NTFS recovery software. If there are two copies of the same file on the disk, and the file gets deduplicated, neither of the copies is recoverable with traditional approach.

All the existsing data recovery software working with NTFS will need an upgrade to be able to recover deduplicated files.

Actually, deduplication makes filesystem more fragile.

For a regular file to be recoverable, you need to find its inode and intact file data.

To recover two identical regular files, you need either of the "inode + file data" pairs. Note that file data comes in two copies.

To recover two identical deduplicated file, you need a long list of items all in good condition
