Hi Mike,
My reply was merely a reaction to your response to Mogget's post which I felt, at the time, was a little unnecessary. However, if it turns out that I have misunderstood then, of course, I apologise to you unreservedly.
It seems to me at least that my experience has been mirrored by others who have contributed to this thread. I cannot say whether our drives are at the route of the problem. My customized laptop was built by Dell (Alienware M18xR1) and the internal drive is of the Blu-Ray variety. I have had it for nearly two years now and thus far the laptop and drive have delivered faultless performance. The only disks this drive has had difficulty with have been from the GenX Scotland series. Apart from 'Scotland Central' I forget which of the others were also affected. However this recent experience reminded me of similar behaviour during previous installations and invariably it was the first disk of each installation that was the problem.
The reason I decided on this particular laptop was Alienware's past reputation for building high spec cutting edge products. My assumption is that they would use high grade components. Whether this policy has changed since Dell purchased the brand name I cannot say but I would hope not.
Anyway, it's still early days. We don't yet know how many will experience problems.
I'm surprised to hear you say that Microsoft have not been updating XP for a while. I have always preferred to apply updates manually and confess I haven't done so for a few weeks. My understanding is that support for XP continues until April 2014, so surely they are obliged to continue with the provision of updates until then.
Again, I'm sorry if I have got the wrong end of the stick and, quite evidently, caused you some irritation in the process. At this stage I'm not certain any of us really know what is at the root of this particular issue. I can only hope it's just a few who have been affected. As ever, time will tell.
Of course I should acknowledge how valuable your input has been. Thank you! We're it not for your timely help, guidance and provision of figures it is quite likely that I would be returning the disks for replacement.
Regards,
Mike
