P35 Platinum and WD Hard Disks unrecognised on cold boot

Hi,
I am having a problem with my WD drives on my P35 Platinum motherboard. Simply, if I power down my PC neither drive is recognised when I boot up again. Usually I have to open the PC, reseat the SATA cables (this may be a red herring) and then when restarted the drives are recognised again.
A simple restart from within Windows (warm boot) works every time.
I would have suspected a cabling connection problem, except that I have tried other cables and also the fact that it is both drives every time, rather than one, other or both randomly.
I have seen other people having problems with the spin-up time of WD drives and have disabled quick booting in the BIOS, but this has not helped much. I have also verified that the RAID Mode is set to IDE, as I am not using any RAID features.
The disks themselves are plugged into SATA3 & SATA4, whilst my Pioneer DVD Writer is plugged into SATA5.
I have the latest BIOS installed but cannot remember the version number off the top of the head, my full hardware spec is in my sig and the 160GB drive is my system disk.
Does anyone have any other suggestions that I could try?
Apart from this issue my PC works flawlessly.
Regards,
Charles

CoolerMaster 700W REAL POWER PRO MODULAR PSU (RS-700-ASAA-A1)
I would suggest not to use a CoolerMaster REAL POWER PSU for your P35 Platinum. There are known compatibility issues with these devices:

not being able to power on with the Cooler Master Real Power Pro 750w PSU. After I push the power button, it will light up for a second and the fans will spin, but it just doesn't power up. I am able to power it on with some generic 500w PSU and my girlfriend's Silverstone 850w PSU, but it always fails to power up when I plug the Cooler Master PSU in.

System powers on for a split second, then powers off. System will boot with another power supply, just not this one.

Just FYI though, it appears (by some comments on Newegg.com) that there is some compatibility issue between my CoolerMaster Real Power Pro 750W and the P35 Neo2-FR motherboard. The power supply worked fine by itself, and the motherboard ended up working fine with a different power supply (Antec Neopower 650 Blue).

We had the same (ground) issues with Real Power Pro 550W, 650W and 750W.
In fact all of them are based on the same "hardware"

They suspect a ground issue, but also have been reported several 12V rail "abnormal behaviours".

My home folder and my Hard disk icon have dissapeared from my mac. How do I get them back?

Try a restart. If the problem is the same, try deleting the com.apple.finder.plist.
Either hold down the option key while using the Finder “Go To Folder” command
and select your user Library in your home folder or use the Finder “Go To Folder” command and enter ~/Library/Preferences/com.apple.finder.plist. Move the .plist to your desktop.
Relaunch Finder (command - option - esc) and test. If it works okay, delete the plist from the desktop.
If the same, return the .plist to where you got them from, overwriting the newer ones.
If you prefer to make your user library permanently visible, use the Terminal command found below.
Show User Library
You might want to bookmark the command. I had to use it again after I installed 10.8.4. I have also been informed that if you drag the user library to Finder it will remain visible.

Hi Jon,
I saw something similar on SPARC when people used s2 (entire disk on non EFI disks) as ASM devices. The workaround we use is to create a new partition, and start it at cylinder 1. This protects the disk label from being overwritten by ASM.

Thank you very much for the early information.
This forum works really fine.

What is the difference between P35 Platinum and P35 Neo2 FIR?

What is the difference between P35 Platinum and P35 Neo2 FIR?
P35 Platinum
P35 Neo2 FIR
BIOS is identical?

The P35 Neo2 is FIR is actually listed as P35 Neo2 FR/FIR. It is what you could call a "modular mainboard". Even if it has the same PCB as the P35 Platinum mainboard, it doesn't necessarily mean, that it will always come with the same features.
If you look at the mainboard manual you will find that the ICH9R-Chipset and Firewire are mentioned as optional features. That means you will be able to purchase versions of this mainboard that will only have an ICH9 chipset and therefore won't support RAID or that don't have a firewire interface.
The abbreviation F,I and R have the following meaning:
F...Gigabit LAN
I... Firewire
R...RAID
In case you decide to buy the P35 Neo2 mainboard, pay close attention to the feature list. Even if the board is listed as FIR by a specific dealer, make sure it really comes with firewire and an ICH9R-chipset. If someone decides to sell the board with the full name that appears on the MSI Support Site (FR/FIR) he might be actually trying to sell a P35 Neo2-F trying to get a better price.

Does OS X throttle hard disk performance on the boot drive?

Does OS X throttle hard disk performance on the boot drive?
I was upgrading my boot drive on a Mac Pro (1,1) from the original Seagate 7200.9 250gb drive to a new Western Digital Caviar Black model 1tb drive.
What surprised me was that disk benchmarking tools (both AJ System Test and Xbench) showed that the new drive had a 30% decrease in speed tests (primarily writes) when actually serving as the boot drive. Put back in the original drive, and while not as extreme as the new drive, it also shows slower write speeds while serving as the boot drive vs serving as an extra internal drive.
In Xbench, the writes are both sequential and random unchached writes, AJ System test is less descriptive, but the write speeds on the new drive are painfully slow to watch.
Hardware-wise, I'd think this new WD
Is there something in the OS that impacts this? Is it something that can be tuned or tweaked? I feel like I'm not getting the most bang for my buck on the new drive (or the old for that matter).
That said, the new drive reads more than twice as fast as the old, and I can feel the difference significantly on boot up (login screen appears faster) and all my startup items load up much faster after logging in.

R C-R wrote:
Keep in mind that benchmarks don't really mean much unless test conditions are the same for each test. Benchmark each drive used as the boot drive & you get a relative comparison of their performance as a boot drive.
Which was really all I was after in the first place, and more as a curiosity than anything else, but it was just too unreal to see the drive lose half its read/write speed just because it was the boot drive. I'd expect, and accept, some relative drop in performance, but there seems like there was something wrong.
My problem gets stranger at this point. I was about to give up on using this drive, it was actually painfully slow to use and I'd gone back to my original drive. I thought I'd give it one more chance as part of some external drive enclosure stuff I was doing.
I put the drive back in Bay 1 on my Mac Pro, and it took forever to boot up, and when I ran benchmarks on it, they were only 5-10% of what I'd seen as a scratch drive, yes, that's 5% total. I actually got a score of 5.04 on Xbench. As a scratch drive, the thing gets in the 90's, and as boot drive it was getting 40s to 50s.
Anyways, after avoiding temptation to throw the thing against the wall, I tried putting it into an eSATA external dock, and booted from it. I am typing this from that boot session right now. The system booted up lightening fast, and benchmarks in Xbench are comparable to when it's a scratch drive, and AJA System Test just showed read/write speeds of 98 MB/s. This is what I would expect.
So now my issue appears to be that my Mac Pro, for some reason, is throttling, make that strangling, this particular hard drive when it is placed in Bay 1 and used as a boot drive. Some kind of hardware issue on the internal SATA bus? Incompatibility with this drive and Mac Pros? It's gonna take some more research or testing I guess.
Very frustrating. Reminiscent of my days with Beige Boxes running WindowsXP; certainly not the "it just works" experience I've grown to love since switching a few years ago.
I'll post back when I find out more.
Thanks again for the followup, and interestingly, I didn't get an email notification of an update to the thread. Odd.

How to rename the "Windows" hard disk icon in the boot options screen

I have been able to rename the "Recovery HD" hard disk icon in the boot options screen by finding its mount mount and running
sudo bless --folder "/Volumes/Recovery HD" -label "Mac Recovery". When I do this for the Windows object, it is not renamed, even when the Windows partition that it represents is formatted FAT32.

Update 2013-05-08 sudo bless --folder "/Volumes/Win OS" -label "Win OS" fails with "Could not write scale 1 bitmap label file". "Win OS" is the name of the Windows folder in Finder.

Hard disk not detected during booting or also it does not show in boot menu.

hard disk not detected during booting or also it does not show in boot menu please tell

you may have a failed hard drive or bad cables, i would check first to see if the hard drive is powering on. if it doesn't try a different power connection, and if it still doesn't start spinning i would say that it is bad and get a new hard drive. If
it does start spinning and just isn't being recognized, try a different sata port if you have the option or a different sata cable all together.

P35 Platinum and Patriot Memory DDR2 PC6400

Hello,
I've tried to adjust RAM Timings, RAM Voltage and RAM frequency manually on my P35 Platinum with BIOS 1.4. I had a reboot loop at CAS 4 so I've tried to put at 1000 MHZ ratio 2:3 after a clear CMOS. It's working.
Now my Patriot Memory is working at CAS 5 ratio 2:3 2,2V and 1000 MHz.
Should I carry on my "quest" to CAS 4 or are these settings good enough? I'm quite lost.....What should I have to do?
Does Patriot Memory owners experienced the same issue? Why can't they be set to CAS 4?
One more thing: After the Post, the Marvell Bios loads but find no hard disk on adapter 1. With Bios 1.1, there was no problem. Do you have any explanations?
Thanks

Hello Spikape,
please list full system specs and provide more information about the specific model/type of Patriot Memory you are using.

I had a reboot loop at CAS 4
Can you try to be more specific about this? Was it an on-->off-->on-->boot cycle or did your system reboot multiple times?

P35 Platinum and NX8800GTS

I have both motherboard and graphic card from MSI (oh yeah ):
- Graphic card : NX8800GTS T2D640OE
- Motherboard : P35 Platinum (MS-7345 v1.x)
And I have question about power connectors on board of graphic card and motherboard. On motherboard there is power connector sweetly called JPWR1, described in manual as "JPWR1 12V power connector is used to provide power to the PCIEX16 graphics card".
But on graphic card is already power connector. I can plug in specific cable that divides in two normal power connectors to connect to power supply.
It is safe to plug in all three connectors to power supply? (one to JPWR1 on motherboard, two to graph card through this special cable)
It is even neccessary to plug in all connectors?

Maybe I will buy another hard drive in future, but nothing more.
I punched your component list into the eXtreme Power Supply Calculator v2.5. Only the Pro-Version (not free) shows the amperages on the different rails (+12V, +5V, +3,3V). The overall wattage if a PSU doesn't really really mean anything without the amperage values.
Anyways, I selected "High End Desktop Mainboard", "2 SATA drives" in the component list, added three 120mm fans, three USB devices and one additional PCI card. I also set CPU Utilization (TDP) to 100%.
The result is:
Quote
373W
+12V: 23A
+5V: 13.4A
3.3V: 9A
On the bottom the is footnote to the option called "Electrolytic capacitor aging" that says:
Quote
When used heavily or over an extended period of time (1+ years) a power supply will slowly lose some of its initial wattage capacity. We recommend you add 10-20% if you plan to keep your PSU for more than 1 year, or 20-30% for 24/7 usage and 1+ years.
When I enter 15% the calculation adds up to:
Quote
429W
+12V: 26.5A
+5V: 15.4A
3.3V: 10.4A
Finally, I overclocked your CPU to 4GHz / VCore 1.4V:
Quote
481W
+12V: 30.8A
+5V: 15.4A
3.3V: 10.4A
I don't know how accurate these calculations are. In any case, they should give you an idea of your systems power consumption. When I choose PSUs I always make sure I have a headroom of about 30% in the +12V-amperages. So if I was you I would get a PSU with about 36-40A maximum amperage on the +12V-Rail, depending if I plan to overclock the CPU or not.
Many users in this forum will recommend choosing a Single +12V-rail PSU. One of the reason is you won't have to worry about problems due to inbalanced power loads or wasted power resources.
If you plan to get a PSU with two +12V-rails, make sure that the maximum amperage on each rail is at least 18-20A. Maximum combined amperage on +12V should not be less than 36-40A.

K8N Neo2 Platinum MB + SATA Hard Disks

Hi,
I would like to use some additional disk in my PC and therefore buy SATA disks.
The OS is WIN XP Pro and I want to keep my IDE configuration which is:
C:\ = IDE hard disk Primary Master
E:\ = IDE hard disk Prmary Slave
D:\ = DVD Secondary Master
F:\ = IDE hard disk secondary slave
and to this I want to add just as data storage SATA 300GB hard disks (¿ up to 4 ? is that possible ?)
regards Rainer

I am not familiar with K8N Neo2-F so consult your manual to confirm my answers to your questions:
1- "Is this also the case for the SATA connectors on the K8N Neo2-F ??" Highly likely since your motherboard is a stripped down version of the Neo2 Platinum.
2- "And do SATA 1&2 require different drivers than 3&4?" For normal SATA operation these SATA drives are respectively contol by your NF3 chipset and you Realtek chipset. When you install or update your Nvidia & Realtek driver package you install all that is required to run normal SATA operation. Should you decide to use a RAID configuration with your SATA drive then another RAID specific driver would have to be installed at system level.
3- "Also, is there a significant increase in performance when going from PATA to SATA on this series of mobos?" My answer does not take into account RAPTOR HDs which are in a super class of their own. Medium to High end latest PATA & first generation SATA HDs in the 7200 RPM class are promoted by their OEM as having respective top transfer speeds of 133 and 150 MB/s. Comparing my Seagate 120 gigs PATA HD to my other two Seagate 200 gigs SATA HDs is not very scientific since they are not all 200 Gigs. Therefore use discretion interpreting results.
a. PATA - Peak transfer = low eighties ; Steady Transfer = high sixties
b. SATA - Peak transfer = mid nineties ; Steady Transfer = low eighties
It has ben a while since I did these PATA/SATA test so I am working from memory only. One thing that however sticks in my mind is that the delta between my PATA & SATA drives, for peak and steady performance, was very close to 12 MB/s in favor of first generation SATA. Could this be possibly related to (150-133), I do not know for sure.
SATA II generation are now coming to market. These new generation SATA II drives will most likely widen the performance gap between them and older SATA I or PATA drive.
Take good care,

WRT610N New Firmware Upgrade and USB Hard disk not working

Hi, I've just upgraded the new firmware, everything seems fine but now my USB Hard disk is not recognizable unless i restart the router. I have a Seagate FreeAgent 500Gigs, and it worked perfectly with the previous firmware. Just wondering if its just me or anyone else has the same problem.
Thanks
I forgot to add that afterawhile the hard disk isnt recognizable again and i have to reset it to get it working

The same thing is happening to me... After the HDD goes to sleep, when you goto access it again you can hear it spin up but you still can't access it at all.

10.2.8 installation and external hard disk does not show on desktop

I just reinstalled OS X 10.2 (by erasing the hard disk during installation) and upgraded with the Combo pack to 10.2.8 . This is an iMac G4 1GHz with a 17-inch display. I tried connecting a Western Digital MyBook with 500Gb through both the USB port and through FireWire. In both cases the hard drive does not appear on the desktop BUT does appear in the Disk Utility program and in the System Information window. Finder, therefore, doesn't display the drive. The MyBook drive is formatted to Windows FAT 32. Before I reinstalled OS X 10.2.8, this machine was running 10.3.9 and the drive did appear (I'm still searching for the 10.3 disk).
Is this an issue with OS X 10.2.8? Given the drive is detected by the System Information section and by the Disk Utility, is there a way of forcing Finder to display it (and allow access)?

Sometimes I have found that I have to turn of the ext. hd and then reconnect the firewire cables. there is a cylinder that is an inch away from one of the firewire plugs, which should be connected toward the tower and the other firewire plug toward the ext. hd. have patience, sometimes it will show up. also a restart maybe...
