WD EIDE hard drive not showing up.

Asked by Blaise

I have a new WD Scorpio 250 gb 2.5 inch hard drive mounted in an external enclosure that Ubuntu won't detect for some reason. It doesn't show up in Computer, or when I type fdisk -l. It showed up when it was unformatted as USB Drive (or the like) It is formatted for NTFS (Out of necessity) any ideas, it could be a jumper problem, the light doesn't flash at all when it is set to default (no jumper) master I am not sure what it is set as now it looked promising when the light turned on. I know it is not the drive, It works fine on Windows. Any Ideas?

Thanks
Blaise

SO it was previously linked through a USB link but you have now inserted it into the machine on the IDE controller?
Do you see anything on screen at boot up to show that it has been recognised by the BIOS?

If not, then no operating system will be able to do anything with it.
That's the first thing to check and is the most likely issue.

Sorry, I guess I didn't word it right, It is in an external hard drive enclousure. I also tried it on DSL (DamnSmallLinux),I doesn't show up on fdisk on there either, could it be a generic Linux incompadibilty? The enclosure is actually a "Media Player" that takes a laptop hard drive, it is supposed to show up as a Mass Strorage Device but maybe Linux isn't seeing it. What is the Linux equlivant of Device Manager, so I can see if it is just ignoring it do to lack of drivers? Thanks

In a terminal window, type

lsusb

That will show you what the drive is being detected as.

Also, worth watching as you plug it in is a terminal window showing

tail -f /var/log/messages

Alright here is the relevant line from lsusb
"Bus 004 Device 003: ID 04b4:6830 Cypress Semiconductor Corp. USB-2.0 IDE Adapter"

And from tail:

So it appears as if it is crashing for some reason, right? Could it be that it is a Western Digital EIDE drive? As I said it works under windows so I think the enclosure supports EIDE.

Thanks for the help.

Wow I officially feel stupid, it needed an external power cord, all better, thanks for the help.
