Solved Quantum HD Jumper Settings

January 18, 2016 at 12:57:24
Specs: Windows, N/A
I need to get files off an old Quantum HD - 8.4AT P/N LAO8O11 Rev 01-A. The plan is to use USB Transfer Case (Currently being used successfully with another old HD). I thought I had the Jumpers figured for the 8.4 AT but evidently not, as I haven't been able to access it yet, and I believe the HD is good. The Label on the HD gives Jumper Settings details as follows:

.. DS Master
.. CS Cable Select
.. PK Park

This detail covers 6 pins, whereas the HD has 8 jumper pins positioned to the left of the Power Input socket. . Apart from that it doesn't say whether the information is to be read from left to right or right to left? Can someone please clarify. Thank you.

A google trawl using the string/search words:

Quantum HD -8.4AT jumper settings

brings up a lot about those drives (quite an olde drive...). And there are numerous versions of them. This is one such link:

It shows the layout etc. of the pins and jumper positions clearly.

and this:

and there are many more...

This string in a Google trawl:

Quantum HD - 8.4 jumper settings

brings this up:

Incidentally one would not expect to have a jumper with 8pin holes on an 8pin socket? Possibly 4 or 6 yes; but not 8... If the jumper had 8 pins and the socket likewise... then no way the jumper would allow assorted configurations?

Many thanks for your very detailed response. This connection provided the solution: You are evidently much better at trawling the WEB than I, as I tried that before posting the query, but found nothing helpful. Your help is much appreciated.

There was key bit that likely confused Google...

Using "all" of this - Quantum HD - 8.4AT P/N LAO8O11 Rev 01-A.

Google got really lost/konphused...

So I broke it into bits and tried a few combinations...

And using:

Quantum HD - 8.4AT Rev 01-A.

as the search term/string also produced the above results, if one browsed more than one page of responses. It seemed that including P/N in any trawl got Google really lost...

Usually the jumper settings for USB enclosures call for master alone, or NO jumpers at all.

Much thanks, NO jumpers at all was the Go!

Thanks. It is clear that there is something to be learned everyday when it comes to trawling information off the WEB. Entering different search combination alternatives never occurred to me.

Using Google is something of a black art, but lots of practice sure helps.

Always keep in mind that all Google can find is words - it knows nothing. Use words or phrases that you think other folk might use.

If you keep getting hits which are littered with something popular then add a space at the end of the search string then a minus to exclude it. So, for example, if you wanted to search for chickens but exclude eggs the search string would be chickens -eggs

Also note that "after" you have searched for something you can choose how far it looks back in time. Click "Search tools" at the top, then look at the drop down under "Any time". These can avoid a history lesson and the more results you get the more you lose focus.

There are a lot more...

Always pop back and let us know the outcome - thanks

Hi Seeker,

would appreciate details of the USB enclosure you (or anyone else) are using as I have a similar requirement of reading old hdd's both 5.25" and 3.5".

Thanks - Mike

I have one these for an olde (relatively speaking) 3.5 drive SATA; works fine and has a decent cooling system to

Icy Dock Blizzard 3.5-inch Enclosure for SATA External Hard Drive

I bought mine from and presumably it's around on other Amazon sites too?

If not wishing to use the drive as regular/"permanent" usb drive, perhaps consider a usb adapter kit; or a dock. However "some" docks don't like "some" WD drives and possibly one or two Samsung too..

Mike, I have the same adapter I am linking below. Works on any IDE or SATA device.
