quick question about partition

my computer i use a 74gb sata for my os.
i store all my company stuff on a 300gb usb maxtor.
i deleted the partion on the usb by mistake durring a windows insall on the 74gb. the 300gb never had a os installed. just formated ntfs for storage, so im worried that i wont be able to recover it myself.

whats the best program i could purchase to recover it? any thoughts?
thanks sooo much.. this hard drive has been down for a few days and its really messing things up for me

I think "recovermyfiles" software is best choice because it cheap but best performance stable and easy use . you can try free version.

did you format the drive with your files on it>?!

after i deleted the partition i just unhooked it. never formated anything
