I have 8 SATA ports on my motherboard. 6 are provided by the main SB chip of the chipset (intel) and 2 are provided by a chip that gigabyte re-branded as their own.
So I have one 750 GB disk on one port and that has a 40 GB linux mint partition and 650 GB NTFS partition of data. I have another 400 GB NTFS disk that works fine too. Problems start when I try to connect a third 320 GB NTFS disk (that only contains data). The disk is not recognised "hot plugging" it. rebooting caused some interaction on boot up but then neither the 320 or the 400 GB NTFS disks were recognised....
So I removed the 320 GB again and rebooted and the 400 GB disk came back (and the 650 GB on the main disk is always visible).
So what the hell is going on ? is it the NTFS file systems causing a problem ? I don't mind changing to FAT32 but can't use linux file systems for data disks because I use them interchangeably on windows systems.
