hello, world\n
so I decided to try two HW technology advancements in one go.
I have a brand new shiny 1TB USB3.0 external disk, that when plugged
to an USB2(two!) reports
da5 at umass-sim2 bus 2 scbus6 target 0 lun 0
da5: <ST1000LM 024 HN-M101MBB 0000> Fixed Direct Access SCSI-2 device
da5: 40.000MB/s transfers
da5: 953869MB (244190646 4096 byte sectors: 255H 63S/T 15200C)
and
# diskinfo -v da5
da5
4096 # sectorsize
1000204886016 # mediasize in bytes (931G)
244190646 # mediasize in sectors
0 # stripesize
0 # stripeoffset
15200 # Cylinders according to firmware.
255 # Heads according to firmware.
63 # Sectors according to firmware.
00A123456789 # Disk ident.
(The vendor, Jmicron, has put an NTFS on it, with a disk manual as a pdf file.
Strangely, I cannot mount it with
# ll /dev/da5*
crw-r----- 1 root operator 0, 236 May 31 15:05 /dev/da5
crw-r----- 1 root operator 0, 237 May 31 15:05 /dev/da5s1
# mount -t ntfs -o ro /dev/da5s1 /mnt
mount_ntfs: /dev/da5s1: Invalid argument
)
When I plug it to one of the two USB3.0 ports (using the xhci driver), I
don't get device nodes in /dev created for it, but instead an ever
growing list of
ugen4.2: <Jmicron Corp.> at usbus4
umass2: <Jmicron Corp. Usb production, class 0/0, rev 2.10/1.00, addr 1> on usbus4
ugen4.2: <Jmicron Corp.> at usbus4 (disconnected)
umass2: at uhub4, port 4, addr 1 (disconnected)
The USB3.0 ports otherwise work fine with a 16BG USB3.0 Stick. Windows 7
can use the disk as well on the USB3.0 port, which makes me look for
things I have missed. For example, my kernel config is stripped down
quite a bit, so it might be that my custom kernel does not have all the
necessary drivers built in or kldloaded. Do I need "device ada"? What is
the magic needed to hook up 4k secotr drives via USB3.0?
Regards,
Jens
