Maxtor 300GB Bios detection SOLVED!
Applies to all Maxtor DiamontMax & MaXline SATA drives! (Mine is 300 GB, 7200 rpm, 16 MB Cache SATA on Gigabyte 7N400 Pro 2 rev. 2)
Many people including me, can not recognize this drives or their motherboards are recognizing them hard, and mainly have problems with detecting them when cold boot.
All this drives have feature calld "Staggered Spin-up Detection". This feature is for servers &/or more than 2 drives to power up one by one, this makes the power supply's work esier when turning on such a system. This also makes it possible to run machines with multiple HDD's with lower power supplyes. They are cheaper also. Anyway this feature must bi off (Disabled) on PC's, or when there are one or two HDD's on the system.
By the SATA specifications the SATA HDD power cable is with 4 pins on the PSU side & 15 pins on the HDD side. By this specifications, Pin 11 is reserved (not used), and should be grounded or pulled low.
These series of Maxtor SATA HDD's are using this pin 11 for turning that feature on & off. When it is on, the HDD is waiting for more initializations more time that any standard Sata controller, Bios & motherboard will wait. So when it is off, the HDD acts like normal PC SATA drive.
Because this pin 11 is reserved for future use by SATA specifications, many SATA power cable manifacturers leave this pin going nowhere instead of grounding it (because it is not supposed to be used), but in our case it automatically enables the feature. So this drives auto sense if pin 11 is connected to power, not connected or grounded.
IMPORTANT: If Pin 11 is not connected or connected to power supply, that means that "Staggered Spin-up Detection" is enabled, & your HDD will NOT be recognized or not recognized all the time by the bios!
SOLUTION: Pull ot the power cable from the PSU & the HDD, and count 11th Pin, start counting from the side with the adge. Ground this pin to your case for example (to some screw)

Hope it helps everyone, sorry for the long POST & for my english, remember... I'am Bulgarian

Cheers and welcome to Short-Media
Great discovery mate.
Here is the text from the original post in case it disapears also
Anyway, the general process involves
1. Unzipping the files to a boot floppy
2. Boot to floppy
3. At the A prompt type g.bat
4. Dont touch it until it says it's finished.
Finally once again.. DONT DO THIS IF YOU ARE ON A RAID CONTROLLER!!!! I could not get it to recognize the drives on the NVidia or the SiL, my guess is, if you can use the Powermax Util you are fine, if not DONT RISK IT...
Good luck.. This finally does really once and for all fix the issue....
One final note, if you guys and Gals can cross post this on any other Forums you frequent we might finally get this issue put to bed once and for all.
After reading "staggerd-spin-detection-pin11.pdf" document your solution
looks ok. But i am still wondering how is it possible to connect pin 11 to
the case?? On one side there are 4 wires connected to power supply,
i guess they should be left alone. It is easy to locate pin 11 on the other side,
but pins are so small that i dont see realy much chance to connect wire
from outside on it. Also don't imagine connecting power cable on disk with
outside wire being sticked on pin 11 at the same time???
Can you add any pictures how you did it?
Did anybody get any information if there exist cables that already have
pin 11 grounded?
looks Djvga doesn't apear here much lately, but have found him on
another forum where (it looks) people are having same (or at least
similar) problems:
http://www.techspot.com/vb/archive/index/t-18228-p-2.html
Meanwhile i got answer from Maxtor support:
1. they are confirming what djvga said about Staggered Spin-up Detection':
"Your enquiry has been responded by one of the senior consultant. According to
his reference 'delayed detection' can't be disabled with jumper, it can only be
disabled if pin 11 is low or grounded.' "
but
2. "Maxtor does not support such amendment and you will need to speak to 3rd
vendor of this issue."
I realy wonder what did they think when applying new feature on disk and
not thinking how is possible to enable-disable it on 'real life'.
Thanks for the reply btw.
1. Install hard drive into computer and apply leads etc. and enable the SATA on the mobo with the jumpers.
2. Go to this link (Maxtor website) and download MaxBlast 4 and run it. It will want a formatted floppy disc to install itself onto so have one at the ready
3. Stick it in the floppy drive and reboot. Follow the on screen command prompts and unless you want a clean install of windows on the new drive make sure you choose to make the new drive added storage or extra storage. Be careful and read the on screen prompts properly.
4. When this is complete click Finish and hit Ctrl + Alt + Del to reboot.
5. When you get into Windows let the wizard look for drivers.
I didn't need to earth or pull pin 11 down I don't know if that's because of the power lead I'm using (one from Maplins) or if it's not neccesary with the MaxBlast 4 but it works :P
The main problem with using Pin 11 is that your typical SATA power connector from the power supply, whether you're using a 4-15 pin adaptor or native power supply connector, grounds pin 11 when you put the connector on. The only time this is not the case is if the drive is connected to a custom SATA backplane interface connector.
I found that I had to put my SATA controllers in native SATA mode or RAID mode, instead of IDE mode, through the BIOS in order for these drives to be properly detected, regardless of whether the staggered start option is enabled.
That done, I saw a white paper about Pin 11 on Maxtor's site that referred to drive activity signal in a table at the end of the document. Only their SATA II drives, such as the DiamondMax 10 and Maxline III, have this feature. Yippee!
Okay, now I had to find a way to isolate Pin 11 from being grounded by the power supply connector...here's where the surgery comes in...and it's not for the timid.
You have to cut through the Pin behind the connector (really not that hard if you have a really small pair of wire cutters) and then solder a wire to the pin on the drive-side of the cut. I then connected that wire to the negative side of an LED, whose positive side goes to +5v through a 90 ohm, 1/8 watt current-limiting resistor.
That's all there is to it!
Have fun!

Perhaps because the person in question wasn't aware of the proper use of this Forum's reply editor.
You're welcome, Spinner. Just modified 8 more drives this morning. When you've done it before, each drive modification takes less than 5 minutes, provided you have the wire attachment ready to solder to the isolated Pin 11.
Evidently, this business with the grounding of Pin 11 to provide staggered spin-up of the drive does not seem to have much to do with the drive's recognition by the BIOS. I've set up three RAID arrays with the 6B300S0 Maxtor drives, using both the Sil and ICH6 controllers on the ASUS P5AD2-E system board, and all the drives are recognised by the BIOS, even though Pin 11 is not grounded (due to its use for LED activity signal).
I think for the BIOS to recognise the drives, the controller to which you attach your SATA drives must be set for native SATA mode, not IDE mode. Usually, setting the controller to anything but regular IDE mode will place it in native SATA mode.
Hope this helps!

not a single problem with any of them.
holy crap- why do u need so much?
All 500gb ibm death stars ! (When I asked what drive)
The 5 250's were in a raid 5.. as a test box.
