I hate to help necro a year old thread BUT.
1. The original posters problem was never fixed. When he says the USB drives are showing up as internal drives, how is disabling USB a solution at all????
2. I have the same issue and have tried several things to no avail.
I have a 24 bay RAID setup plus 2 onboard ASRock SATA ports that are enabled. By my math that should be 26 ports.
If I have 12 drives plugged in (10 on the RAID, 2 on the ASRock SATA ports), I plug in the USB drive and it comes up as the port 21 internal drive.
I've plugged in 21 hard drives, and it fills slots 1-21. When I plug in a USB drive then, it comes up as drive 22, still showing as an internal hard drive.
I intend to use the USB drive for the Key Manager, which doesn't allow you to save to any drive except a USB drive.
With the original config, the USB drives work perfect, but all the additional hard drives beyond 12 show up as eSata:
Set as 24 ports with esata enabled, the USB Drives show up as internal drives, and cannot be selected for the encryption manager:
Set as 26 ports with esata disabled and 6 USB ports, same problem with the USB drives:
So I thought, possibly I need to set it to only 20 disks so that the 21st disk would come up as a USB Drive, but even set as only 20 internal disks, the thumb drive comes up as an internal disk 21.
Anyone else run into this or have a solution?
Thanks in advance.
Edit: I've also tried kicking it all the way up to 32 ports, but the system just goes into a reboot and prompts to re-install Synology.
Also just tried doing another edit at only 28 drives with the same thing rebooting and asking to re-install synology.
Notes about the system:
I'm using Xpenology with Jun's Mod 1.02-alpha, a Lsi Sas 9201-16I and an Intel Port expander. All of the drives are seen fine, it's just the USB drives that I'm having a problem with.
