I am trying to upgrade my HP a1719n from Vista SP2 to Windows 7 Home Premium (using the upgrade DVD) without having to do a clean install. Before the installation starts I get this message. The following issues are preventing Windows from upgrading. Cancel the upgrade, complete each task, and then restart the upgrade to continue. Windows needs to be restarted so necessary changes to system files can be made before continuing.For these items, make the following changes: Install updated drivers for the following devices. Open Control Panel and search for "update device drivers". Disk drives: Compaq SCSI Drive Array I have gone to the only disk drive in Devices and tried to upgrade the driver for the only disk drive listed as well as the storage controllers and it say I have the newest ones. I have tried deleting the driver and re-booting and it still does not work. I have upgraded the BIOS and still nothing. I have searched all the devices in Device Manager and cannot find anything resembling Compaq SCSI Drive Array. I have used Microsoft and HP Update as well as the forums on those sites. I have tried switching from RAID to IDE to ACHI in BIOS and still nothing. Any suggestions? Thanks.
