For several years I have been happily running a 3-disk RAID5 using Intel Matrix Storage Manager on my office Dell Precision T3500 under Windows 7-64 bit. In May the Microsoft upgrade tool migrated it to Windows 10 (unprompted), and a few weeks later I noticed that the Intel matrix storage console was no longer available, so I can no longer monitor the status of individual disks other than via the BIOS Ctrl-I facility. I can't roll back to Windows 7 because Microsoft has deleted the windows.old data (which I now understand happens after a month).
Last week a disk failure occurred (array degraded notice during startup, slow computer, Error ocurred message by one of the disks), so I have replaced one of the 3 hard drives (WD black 1TB), expecting it to be rebuilt into the array as occurs under Windows 7. This doesn't seem to happen, despite a successful message when the new disk is recognised saying the disk will now be rebuilt in the operating system.
What actually happens is a BSOD immediately after the drive change (I have had two BSODs so far, UNEXPECTED_STORE_EXCEPTION and KERNEL_DATA_INPAGE_ERROR). After an error report/reboot all appears fine but the drive never gets rebuilt and on subsequent reboots shows up as an Unknown Disk in the BIOS utility.
Device manager reports my RAID controller (Intel(R) ICH8R/ICH9R/ICH10R/DO/PCH SATA RAID Controller) is on version 8.9.2.1002 from August 2009. I am unsure whether newer versions (I see it is now called Intel RST) will be compatible with my hardware and am nervous to try in case I end up with a brick. I can't find any advice from Intel. Dell won't help because it's an old system. Microsoft, whose fault this is, said they would get back to me within 2 days but their latest response doesn't fill me with confidence ("Sure, I will look for all the possible solution to get this issue fix and I will email it to you once I found any good solution.").
So my immediate question is:
How can I get my replacement disk recognised and rebuilt into the array?
