Will running a HDD as slave drive corrupt its OS??

Will running a HDD as slave drive corrupt its OS??

I have two hard disks, same capacity, brand, etc. They are both installed with Windows 7 Professional.

If I run one as the master hard disk (ie I'm using the OS on it) while the other as a slave hard disk (ie its OS isn't being used and I can see the Reserve System volume that I normally won't be able to) for storing media files, will the OS installed in the slave hard disk get corrupted if:

(a) you simply have it as the slave drive and turn the PC on
(b) the OS in the master hard disk gets corrupted, eg registry keys get corrupted or deleted by accident
(c) there is a power failure and the OS in the master hard disk gets corrupted
{d} the main hard disk hangs while in use and you have to shut the PC down improperly

None of the above. Your hard drive should be fine.

The exception is D. If you have to shut down improperly, no matter what configuration the drive is in, you risk data loss if it is being written to.

If I am writing a file to the slave drive, does data loss only happen to that file that is being written to? Or does it occur hdd-wide in the slave drive and randomly affects other files?

On the other hand, if I am writing a file in the master drive in the sense that I am copying a file from the Slave Drive to the Master Drive, will any file in the slave drive become corrupted?
