I'm in a country/city with no Apple Store to speak of, and plan on being here for quite some time. Having experienced a combination of the "Flashing Question-Mark Folder" and "No Entry Sign" utterly out of the blue yesterday, I proceeded to run the litany of boots and start-ups recommended throughout the net with nothing to show for it. The hard disc was completely unreadable, disc utility etc. would not work at all. Having given up hope I proceeded to take the computer in to the only known official reseller (www.istore.am), and they determined that the the unreadability of the hard drive stemmed from a faulty internal connecting cable. They have offered to replace it for $86. I've checked this piece of hardware out online, and have found that it costs about $50 on ifixit -- presumably prior to shipping. Am hoping/would appreciate it if someone can advise me on whether this seemingly inflated cost is utterly unreasonable or, more or less, my best bet.
