Windows 7: Windows 7 does not see my disks

24 Oct 2010   #1

Windows 7 Pro (64-bit)
Windows 7 does not see my disks

I just installed Windows 7 Pro (64-Bit) and it doesn't show all of my disk drives.
My disks (there are 7) are attached via two RAID controllers an Intel ESB2 enbedded controller and am AMCC 3ware 9550SXU-16ML. The Intel controller has one RAID 10 drive (This is my C drive and Windows see it okay). The AMCC 3ware controller has six logical disks, a RAID 5, a RAID 1, a RAID 0, and three single disks. For some reason Windows only see the RAID 0 drive.

When I go into Device Manager, under Disk drives it displays five 'AMCC 9550SXU-16ML SCSI Disk Devices', all with a status of 'working properly'. They all have the same driver, v6.1.7600.16385 (win7_rtm.090713-1255) from Microsoft. If I try to install the latest AMCC 3ware driver, Windows tells my that the installed driver is newer.

I also went to the AMCC 3ware management software and verified that all six logical drives are recognized and working properly.

Does anyone have an idea as to what is going on, and how to fix it?

BTW, this system was running Windows XP Pro (32-bit) before I installed Windows 7. On the XP system all seven drives were working find.
