I think I already know the answer but thought I'd make sure.
My system came equipped with the RAID0 configuration and I would prefer to have RAID1 enabled instead for the added reliability. Certainly willing to sacrifice the 500GB for the added piece of mind.
A couple weekends ago I disabled/broke and then re-enabled the RAID0 in an attempt to resolve the random system shutdowns, etc. As I was doing that I noticed that there was no option for RAID1, just RAID0. So I suspect that the Intel Matrix Storage controller card I have installed only supports RAID0?
No posts from me since several weeks now... I had the same RAID/HDD related issue but my XPS420 was running quite ok, until this week. Almost 4 weeks without any problem...
I'm trying to determine what could have been the key factor (as, obviously, forums posts regarding Hard Disks replaced are not so optimistic...).
I'm still with exactly the same hardware (no HDD changed) so, basically, I'm focusing on software :
As written above, I had 4 weeks without any glitches on the Storage Raid sub-system. I have been announcing on this post the fact that, following Dell's advice, I installed Service Pack 1 RC1 on my Vista. Then, few days later, SP1 RC1 Refresh...
But beginning of this week, I had to re-install from scratch my Vista. Somewhat time-consuming process so, basically, I had to do it over several evenings... (OS, Drivers, Applications, Personal data,...)
I had 4 weeks without crash... But during the day I left my XPS420 running, with Vista installed BUT without any Service Pack 1,... It crashed!!
Now, I once again re-installed SP1 (so called SP1 RC1 Refresh 2, supposingly the Final one, downloaded with official WU process anyway). That was 2 days ago. No crash since then.
Rather difficult to have any firm conclusion here... But from my personal experience, I tend to believe SP1 is contributing to stabilize the RAID issue seen on XPS420...
What is your own experience on this one ?
