Why can't my target computer find any accessbile disk drive?

I have a problem to enable data logging for my Simulink Real-Time model. At startup, the target computer shows the error: no accessible disk found. It has a SATA drive with 5 partitions, of which 2 are of FAT32 format. The error message only appears once. What is the reason that the partitions are not being recognised?
I can add that I'm using an RS-232 connection and booting from a USB drive (Secondary IDE and Graphics mode enabled). Maybe it's also useful to say that the disk driver makes the hard disk appear as SCSI (under Windows).
Thanks in advance

This will occur if the Simulink Real-Time kernel cannot detect the partition created by a third part program. The documentation provides an example of how to format and partition a disk for use as a hard drive on the Simulink Real-Time target machine:

Ok. Unfortunately creating a partition this way didn't solve the problem

I know that this post is very old, but just in case it helps anyone...
If the drive appears as SCSI in Windows, its likely a RAID controller and the Target OS doesn't have a diver for it. If you access the BIOS settings at boot-up look for any options mentioning RAID and try to disable them, on some motherboards this may also mean that you need to use a different SATA port for the drive so keep that in mind while troubleshooting.
