USB 2.0 External hard disk not recognised

[Rajesh]

Archived from groups: comp.sys.ibm.pc.hardware.storage (More info?)

I have bought Seagate 160GB internal hard drive (Ultra ATA/100, 3.5
inch drive). Now I want to use this as external hard disk. I am already
having 5.25" enclosure and I have tried connecting it. The new harddisk
is recognised but issue is I am not able to see this hard disk
anywhere.
When I double click the "add remove hardware" I find
USB Mass storage device. and if I click on display device components, I
find disk drive under that.

In computer management, Disk management, I dont find this drive.

Under device manager, disk drive, I find a box without any name.

Does anybody knows whats the issue with this drive and how to correct
this problem ?.

Note: It is recognised if i use it as internal hard disk.

Maybe a master/slave jumper issue? I have not had problems with drives
jumpered either way, but maybe your enclosure is more picky.

But there is only one connection...
Why there will be a issue with master/slave, if I use it as a external
hard disk ?.
I do have another external hard disk from from western digital and it
works without any issues..

Thank you very much..
That solved the problem...I never knew there is a switch behind to make
it master..it was in the cable mode...

I see you got it fixed, cool. The jumper issue isn't quite the same as with
internally used drives. The only reason you would set a jumper one way or
another in a USB enclosure is to make the drive compatible with the USB
enclosure. Glad it helped!

Oh yes it is.

Which is no different for internally used drives.
The drive needs to have an address and that is what the M/S/CS jumper(s) do(es).

What I meant is, you could have 10 USB drives all set to be master. From
Rajesh's response to my suggestion it sounded like he didn't understand why
there is an issue if the drive is in a USB enclosure as USB has no master
slave issues, its just USB. While it is true USB has no master slave
issues, the USB-ATA interface might have some requirements of the drive.

So you can with drives internally, provided that you have enough channels.

Yes, he appeared to say that the IDE device doesn't need a device ID
if it is an only device.

> as USB has no master slave issues, its just USB.

That's assuming that there can be only one device per USB connector.
I don't think that that's true.

> While it is true USB has no master slave issues,

Neither has IDE.

The same as the 'normal' IDE interface.
It may be different for the bridge *firmware*, dependent on whether it
supports 1 or 2 devices and/or whether it self configurates or needs a
specific ID to work with.

Hi.. try doing this

Verify your enclosure if it's USB1.1 compatible, else you're doomed!
Change jumper setting to Slave,
update your BIOS.
