How to jumper (external) USB hard discs? Jumpering S-ATA hard discs on master or slave?

[Timo Price]

Assume I mount another USB IDE-hard disc to my current system.
How should I jumper this hard disc?

Say thes external USB hard disc is NOT an IDE hard disc but an S-ATA hard disc.
Is it important for them as well on how to jumper it: To master or slave or cable select?
Or are terms of "master" and "slave" only important in the IDE world?

SATA drives don't have master/slave jumpers, they are one drive per
controller connection.

None of the SATA drives I've worked with have any jumpers.

None of the SATA drives I've worked with have any jumpers.

The jumpers wouldn't be for Master/Slave/Single as there is only one
device per connector

Correct, Master/Slave are only for the IDE world (PATA). SATA drives
don't have jumpers and don't need any physical setups.
Be sure you have a controller and connectors for SATA if you go for a
SATA drive. You might need a PCI card to use SATA if your mobo doesn't
already have the connectors.
Also, XP has SATA drivers but ... not all SATA drives are created
equal and sometimes they will require installing their own drivers. No
idea whether that's good bad or indifferent but I dislike things that
need extra drivers when XP can handle it. My SATA drives do work very
well and I love the non-mess their cables create inside the case.

Cheers,

If you buy one that's already in an enclosure, then you won't have to do
anything other than plug it in.

You don't. USB has a different bus architecture. The system will
see it as a SCSI disk (or similar) and that bus has allways supported
more than two devices.

Say thes external USB hard disc is NOT an IDE hard disc but an S-ATA
hard disc.

It is an USB HDD. The computer does not see the disk interface.

master or slave or cable select? Or are terms of "master" and

They matter in the SATA world as well (only everybody is a master
there), but this is USB and the question is not relevant.

Normally you jumper an IDE drive master for a USB external enclosure.

There is no master/slave/CS with SATA drives.

Only possible with IDE, yes.

And yes, a SATA drive has more future, you can use it internally later if you upgrade the PC etc.

A sata drive has no master/slave jumper, it may have a jumper to force a
sata 2 drive to use sata 1, depending on age/make

 

[Ed Light]

To answer part of your question, if you're putting a SATA drive in a USB
enclosure that only supports the older, slow SATA standard then you may
need to put a jumper on the drive to slow it down to that. I forgot the
name of the standard -- maybe SATA 1.1? 1.5?

Master. In the case of a Western Digital ide hard drive, master alone
(master). As opposed to master w/slave.

Your PC is "talking" to the interface chip on the external hard drive box,
not directly to the onboard hard drive. The jumpering configuration is
important to that chip, not the PC.

No such animal on SATA drives. Some SATA drives have a slowdown jumper.
The 2 that I have a slow-down jumper from SATA2 to SATA1.

That, and cable select (CS). Western Digital has 2 master jumper
configurations. Master, and master w/slave.

SATA disks don't have M/S/CS jumpers. Each is a master on its own channel.

How you jumper IDE disks in external USB cases depends on both the case and
the drive. For example, I find that some WD drives are listed as properly
being jumpered as Master for a case, but only work if *no* jumpers are
installed.

Once the drive is in the case and is recognised properly, jumpering ceases
to be an issue.

I usually plug them cable select, but I have experienced it working with
pluged as Master or Single drive. I have not tried plugging as slave.

To date, I've found no external USB/1394 case that does not require an
onboard ide drive jumpered electrically as master.

There is no difference between the "master" setting, and no jumper(s)
installed on Western Digital ide hard drives. This is also called "master
alone" in some circles. There is a difference between that, and the master
w/slave jumper setting on Western Digital ide hard drives. Yes, I've also
used the funky 9 and 10 pin configurations on some older Western Digital ide
hard drives.

There no master on a SATA serial line.
