Hi
It's been a while since i've listed anything on this brilliant forum due to the fact that with people like Brink/ Shawn giving you infomation regarding a problem you've got, you suddenly don't have that problem anymore!
So, as this goes against my usual grain, in the space of just 4 days I have had 2 crcdisk.sys boot errors, which have resulted in 2 complete rebuilds - not a happy bunny, I can tell you.
I'm running an ASUS P5N32-E SLI that's fully flashed to latest BIOS and have happily run it with a Q6600, 4 gig RAM and Vista x64 Ultimate on SATA RAID0 for the last 18 months and had no problems whatsoever. However, on Monday I put the computer to sleep instead of shutting down, so just pressed the "off" button and went to bed - big mistake! Next morning, defaults have been loaded at POST, it wouldn't boot and going through safe mode showed the dreaded "crcdisk.sys" stopping place in the boot list, so tried and tried to no avail and then spent 12 hours reloading, updating and installing right up to SP2.
Woke up this morning, switched on and suddenly the POST screen flashes up and it says that defaults have been loaded for some reason and lo and behold! we're off again with "crcdisk.sys" error and once again, it's taken another 10/ 12 hours to get back to a semblence of order.
My question is this: is there ANY workaround when faced with the crcdisk.sys error? Bearing in mind I run a SATA RAID set-up, so the problem does appear to be the loss or corruption of the Nvidia SATA RAID boot drivers. Surely someone must have worked out a way of salvaging their operating system rather than doing a rebuild? I have tried repair but that doesn't work, even if you wait for 3 hours for it to end its cycle, nor does the memory check do anything of value.
Have searched Google but nothing's come of that, so i'm hoping one of you guys with the big brains can sort this out.
By the way, sorry if in wrong topic/ section.
Many thanks
