“Master with non-ATA compatible slave”

This enables the use of a Seagate HDD with an SSD in a G3 Blue & White.
Which leads to same application in early G4s and possibly the Quicksilvers?
AND it may depend upon the age of the HDD - compared w/ newer Seagates?


Stumbled onto and tested this just yesterday.

Some Seagate drives [tested here so far, with a Barracuda 7200.7, 7200.8 and an ATA IV]
offer the option of a FIFTH kind of jumper setting - “Master with non-ATA compatible slave”.
And while this is not noted on the Seagates just mentioned above… it works with them.




Normally, accustomed to this graphic on Seagate HDDs:



Until I found this on the bottom of a drive salvaged from an IBM PC.
*Of course it’s sorta “flopped” / being on the bottom of that HDD.



Two jumpers first hinted at here with another HDD:
From: http://macos9lives.com/smforum/index.php/topic,6127.msg46280.html#msg46280
                            *That’s a Seagate on the bottom.


*Thanks once again to Petros90 and his incessantly stubborn G3 B&W.

Possibilities?

Let’s say you’ve a B&W G3 or an early G4 (*w/ hopefully a Seagate HDD)
…just chock full of software or files that you’d really not care to remove
or erase AND you want to upgrade / add an SSD.

Instead of having to copy it all over to the new SSD, it can still reside
within your machine along with the newly added SSD.
*If not a Seagate… maybe clone to one?

OR - you may wish to have a (Seagate) with this capability:
   “Master with non-ATA compatible slave”
- as a backup or for backup-bootable “maintenance” tasks.





Further Testing:

Setup was a necessity here with the G3 B&W and an AGP 450 MHz.
And likely, other “early G4s? (Didn’t test in a Digital Audio machine.)
But it works in the Quicksilvers too.

However, it wasn’t completely necessary in the Quicksilver.

Also was tested in a Quicksilver (with B board) as above… BUT with a
Western Digital HDD. This test did require booting from an installer disc
in order to first “define" / choose either the Western Digital OR the Inland
SSD as Startup Disk. The Western Digital was defined as Master and the
Bribge still had no jumper. After installation in the QS, zapped the PRAM
at Startup - and then both disks mounted upon reboot.

NO “two jumpers” required on the Western Digital.
(In the Quicksilver... but DieHard may need confirm this.)

AND thanks DieHard for the most concise clarification below.

Great find !  You are awesome After thinking about it, during the last Quick Silver hell, I had a feeling that it was an un-documented setting on the Seagate Baracuda 7200.7

So just to clarify...

All Segate Baracuda drives tested so far (7200.x) have the setting "Master w/non-ATA compatible slave" even though the pictured jumper settings may not list this as an option.  Again, this setting is absolutely critical to get an SSD and a mechanical drive working correctly on the same IDE cable in a B&W G3 and in a QS G4 using a "Bribge" IDE to SATA adapter and possibly some other brands. This critical setting is achieved by jumping the (2) sets of pins (5,6,7,8) that are closest to the IDE Cable connector.

This is just a repeat of what FBz explained, but I paraphrased for future documentation, if one wants a short explanation.

As I have spent many hours on this exact scenario, using (2) drives with cheap SATA to IDE adapters and this info. will save your sanity.  There are many combinations of jumper settings that yield a G3/G4 tower that does not boot, or take 2 to 3 minutes to time out and then boot.

Last note: If you intend to use one large SSD drive, then this discussion is a mute point.  The "master" setting on the cheap IDE to SATA adapters work awesome in single drive setups, both mechanical or SSD.

So it can explains why my mSATA SSD does not work with my old hdd in my Yikes!
I will have to check the jumpers on the hdd

Thanks !!!

Hope you have a Seagate HD on the bottom.
Reportedly the only drives capable of the double-jumper!

An IBM Deskstar might be a good option for a bottom drive.  There are a lot of different jumper settings available.  I have a bribge adapter now so I'll try it out.

My IBM/Hitachi Deskstar was a no-go.  I tried every configuration and the results were either the Deskstar not being seen or neither drive being seen.

Model # of the drive is : IC35L040AVER07-0

seriously: forget this generation of HDs, they are terribly loud and slow.

you will be really happy with anything ~2006 or newer, quiet and almost 3 times faster. (f.e. maxtor diamondmax 160gb+)

or use your SATA adapter.
