Where do I found the usb-hdd ?

[yabbah]

Hi out there, I just plug in an 2TB sata-hdd through an usb2sata cable, worked flawless in both windows and mac.
But on my linux-machine I cant even find the drive.

It should be named /dev/sdX ?

I got /dev/sda to /dev/sdh, and thats my internal drives, nothing more. Is usb-hdds somewhere else?

Please help!

Hello and Welcome.
I'm not much familiar with USB2sata but we'll give this a shot. Open a terminal window and issue these commands with sudo or su -, depending on your setup.

fdisk -l

This should tell us what your disc partitions look like. Notice that's a lowercase L and not a 1.

mount

This will tell us what is already mounted, where it's mounted at and other useful info.
Post your output here using the forum code tags, please.

All those disks is already in use.

The new disk should be /dev/sdi, this output is from dmesg:

Initializing USB Mass Storage driver...
scsi8 : SCSI emulation for USB Mass Storage devices
usb-storage: device found at 2

Any ideas?

Does the device exist in /sys?

ls -ld /sys/block/sd*

Do the block devices exist?

ls -l /dev/sdi /dev/sdi1

If not, you can always make them:

mknod /dev/sdi b 8 128
mknod /dev/sdi1 b 8 129

So yes, it exists. But:

[root@yabbah dev]# fdisk /dev/sdi

Could not read /dev/sdi
[root@yabbah dev]#

:/

[atreyu]

what does lsusb report - any info on that drive? you might need to install usbutils first.

It seems to find the usb2sata anyhow.

What's your kernel version/distro?

Also see here - maybe power the drive up first, then plug in the USB cable.

[yabbah]

his kernel is 2.6.18, and dist is ClearOS (a router/nas dist).

I already tried power it first, then plug in the sata-cable. No difference. :P

[atreyu]

pretty old kernel. can you boot a current Live Linux CD and see if that makes a diff?
