The short answer is a 'yes' - when a file is deleted from a hard-drive, the data is still there, only the path is removed. The computer assumes that the space is now empty, so can write over the supposed empty space.
Data is stored on the hard disc. The more memory hard disc has the more data can be stored.
Windows is installed in a separate section of the hard disc and will not affect your existing data. As with any major changes to a hard disc it is advisable to have a back up copy of your hard disc on an external disc before starting the installation.
The hard disk is a device which attached in a CPU where data , program ,and folder are being stored .
the right place on the hard disk has to be found, then the read/write head must be placed there, then the sector (a small part of the hard disk) is read or written, if it's read, the data is moved into the memory, maybe by the DMA (Direct Memory Access) Controller. Is it's a write operation, the data must first be given to the Hard Disc Controller.
Personal preference - either form is acceptable !
They store digital information in a relativly permenent form. Some hard drives called 'Hard Disc Drives' store data magnetically on a metal disc. Newer hard drives called 'Solid State Drives' store data electronically on flash memory.
The data is permanently moved to a specific location on your hard drive where it is placed back in cue to be overwritten by a new data.
It stores data magnetically in a manner that the computer can access relatively fast.

Hard data recovery is generally needed when a PC hard disc has failed. In this instance it is usually impossible to repair the disc and it will need to be replaced so the data recovery will focus on getting whatever data can be found on the current system by whatever means possible, assuming that it hasn't been backed up elsewhere.
First one needs to identify the problem before one can determine how to repair it. If one only needs to recover data from a broken hard disc drive, there are many programs and tools online for data recovery from broken drives.
I also found out that I have to preform clean install to have 64-bit version of Windows 7 because I have 32-bit version of XP. Can I install it on one hard disc without loosing my data on another hard disc. Is this clean installation going to delete data from one hard disc where I want to install it or is it going to delete data from both hard disc including one I don't plan to install Windows on?
