Dear Experts,
OS: WinEC7 , Platform: freescale i.mx53 custom board, 512MB RAM.
i.mx53 has SATA interface directly.
My sata storage is 200GB size. I divide it to 4 partitions.
Each partition is about 2~8 GB size, FAT32.
When I connect SATA storage to platfrom through USB interface,
WinEC7 can recognize 4 partitions.
But when I connect SATA storage to platfrom through SATA interface,
WinEC7 can only recognize 2 partitions at most.
I can see 4 partitions in Control panel/Storage Manager/ATA Hard Disk Drive.
But only 2 partitions be mounted. Partition 3 and 4 can't be mounted.
Here is the registry section.
