mounting external hard drives

Moebius · 06-17-2004, 04:49 AM

I have three external hard drives and an iPod. One of the external hard drives and the iPod are firewire, the others are USB2.0. I think I have all the correct things compiled into my kernal, but I don't see any /dev/sda1... in fact when I do a ls /dev I don't see anything about sda.

What should I do?

Thanks.

whenever I connect a new device like that, I always run dmesg to see how the system reacts to it.
If its a usb device I'll usually try something like dmesg |grep usb.

Look for a program called usbview.

It will list what's connected.

This should help tell you how the kernel sees the device (ie.. what type of drivers you'll need)

I gather that usbview simply displays info from

/proc/bus/usb/devices
/proc/bus/usb/drivers
/sbin/lsusb

dmesg gave me some good info:

USB view also gave me some good info. It found my USB mass storage devices, but I'm not sure how to mount them now.

Code:

And the other one looks pretty much the same.

And what about firewire?

Thanks for the help, let me know where I should go from here.

OK, I figured it out. It was because I hadn't compiled SCSI support into my kernel. I didn't know SCSI had anything to do with USB, but I guess it does.

Thanks for the help guys.
