Whoa whoa... hold on. I use a Synology DiskStation and I quite frankly don't see how it's even possible for their software to modify your Mac's internal drive. Their software simply manages their devices via a web browser, and the firmware is actually applied by the device itself to its own drives. What makes you think your Mac's drive was modified? Are you not able to boot off it?

thank you for your questions Lifeisabeach. I am new when it comes to using apple products. I have only had the imac for less than 3 months and wanted to attach the best when it came to back-up devices etc. I take responsibility for aborting/cancelling the synology install 30 minutes into the installation. The 'status' light on the Disk station was blinking orange/amber and in my lack of knowledge, I cancelled. shortly after that, there was a LION OS 10.8 update which i did. after that, whenever i placed the synology disk in, it kept asking me for a file path which i can never find without opening some other file.
I noticed the Macintosh HD (in Finder) had that it was modified and the date and time i aborted the synology installation is the same date and time of the modification. it also bears an earlier date-the one upon which I received the imac- i wanted to restore the imac HD to the earlier date, but have learnt through this post and the helpful responses, that unless i had a backup, this would not be possible. I did not back up as I was attaching synology to be my back-up. So now I am opting to re-install the OS X DVD that came with the imac and start from scratch with synology as well.
I hope this made it clear. Now that I know you are a synology fan as well....how long does it take for it to do the inital setup? I have a ds212j with one 3tb HD in it.
Also, from my posting above, which of the following 3 DVDs do I use to re-install? Application install DVD; MAC OS X Install DVD and MAC OS X Install Disc 2
Also, will I lose my Microsoft 2011 and my pages applications? I want to reinstall the OS without losing my applications.
