So my ever-untrusting dad bought a pre-built for our company, installed with OS and everything, just before Xmas. During the hols, a guy came and installed financial software, together with networking. He didn't install anything on the pc in question, just on another pc which he networked... By that time I still hadn't seen anything. Now yesterday I went to work after the hols break - in a quick glimpse I noted that very weirdly that on the new pc the HDD was Drive G and XP was installed there. There were also 3 or 4 virtual drives installed, for what purpose I don't know (and am very curious about). I mean in the 'My Computer' there is Floppy Disk A (there's no floppy drive but I can disable that from the bios if it bothers me), then there's the HDD Drive G, the 'real' ODD I don't remember the letter and a further 3 or 4 more virtual ODD drives... I just can't understand wtf got installed on this pc... I realised all this because I went to work, plugged in my pendrive and got zilch, and did some checking out. I went to Disk manager from the Device manager and saw that my pendrive was being read as Drive C. So I went back in 'My Computer' and also noted that the Network Drive was also Drive C. I realised that there must be some conflict even though I'm not well versed in networking...(I mean the networked drive is C on the parent pc but I don't understand a heck as to whether it has to appear as C on the receiving pc or not?) however I assumed that changing the USB drive letter would do the trick... Now I didn't want to meddle with the Network Drive otherwise I might not be able to work at all from the pc, moreso since dad just bought this pc before xmas, moreso since I didn't create the network myself and even moreso since my dad's abroad and I know that if something that I personally do happens to go wrong there'd be the third world war over here... Notwithstanding, I renamed the Pendrive C drive to drive M, praying that if the network got a problem I'd hopefully solve it by re-naming as it had been previously or calling the tech who installed the financial software on the other pc and created the network in the first place. But *whew* all worked fine. Nonetheless I put myself in the shoes of a person who normally wouldn't be doing this kind of stuff... so I renamed the Pendrive back to Drive C and called the place where dad bought the pc from and played naive. Me: Hello, we just bought a pc from you and it can't read my pendrive even though I've tried both 2 front ports and 2 back ports. Him: Did you try another pendrive. Me: Yes. Him: Did you try same pendrive in another pc? Me: Yes. Him: Wow that looks bad. Me: hmmmm Him: It's best you bring the pc over, we might need to change the motherboard Me: Listen, I called because I assumed there was something simple which I might be overlooking... Him: I can try giving you instructions on the phone but I'm sure it'd be very difficult for you to understand what I'm saying... Me: Well, can't we just try at least? Him: OK take a printer, webcam, whatever and stick it into USB so we see if it works. Me: I don't have anything here... Him: C'mon don't you chat and webcam at work? Me: *makes a silly lol* no honestly I got plenty of usb stuff at home... Pause... Me: I'll bring stuff from home and check it tomorrow then? Him: Go into disk management (control panel, device manager, storage etc etc) Do you see your pendrive there? Me: Yup, it's Drive C. Loooong pause..... Him: That can't be. Look again. Me: I have the monitor in front of my eyes, Pendrive is Drive C and XP Pro is on drive G. Him: That's impossible. Me: Hmmm, shall I take a screenshot? (I was itching to tell him I wasn't blind or anything but thought against it...) Him: That's bad. Verrry bad. Very bad of the guy who installed your XP, installed the financial software, done the networking stuff and mucked all this up. You have to bring the pc back here for a re-install. Me: Uhhh, we bought the pc from your company already installed with the OS... ahem? *** very long pause *** Him: The OS can never be installed on a drive which isn't called drive C. It will create problems. Some tech of our company made a mistake in naming the HDD Drive G, I admit that and we'll correct the issue free of charge in this case. Sure your pc might work fine for now, but you might install programs on it and find they don't work because they assume that the OS is on Drive C. Me: OK, I'll speak with the other directors of the company (which is the professional form of saying 'dad' ) and be contacting you on this manner. Now what I would like to know - Is it really that important for the OS to be installed on Drive C or is this guy just creating a storm out of a teacup? I'm nearly persuaded that he's genuine, after all he doesn't want to charge any money... but on the other hand he's just an employee so he still gets paid whether he charges money or not... However for our work to go missing a computer it's just not practical, unless what this tech is saying really is so problematic. So, if there's no problem at all I'd just leave stuff as it is and rename the USB back to Drive M. So - what are your views on this?
