mystery HDD recovery partition

[Zacthejam]

Hello,
i have a toshiba satellite running windows 7,
my internal hard drive has two partitions,
WINDOWS (C
and
DATA (D
the data partition is 250gb large and it is empty and the only thing in it is a hdd recovery
thing.

What is it for , do i need it , can i delete it?
Thanks

No, don't delete anything.
If your machine crashes, you will need this to do a restore.
