"Negotiated Link Speed" question to make informed decision on upgrading my hard drive
This is my first post on any help forum I've made in a while as I have usually found answers if I looked hard enough. I am glad I caught and investigated this detail before buying anything that may not improve. What I really want to do is top my macbook out. I'll try to provide as much useful info I can and appreciate what clear insight anyone has for me.
While comparing the specs of my current hard-drive to the SSD ones, I couldn't help but notice these line items:
Link Speed: 3 Gigabit
Negotiated Link Speed: 1.5 Gigabit
While I spent a great deal of time researching similar concerns I could not find the answers that I needed, or made any sense. I'm going to include the hardware specs of my system to make this easier for anyone who is more knowledgeable about what is causing the 1.5 limit. My current stock hard drive is a Seagate Momentus 5400.6 SATA.
Serial-ATA:
NVidia MCP79 AHCI:
Vendor: NVidia
Product: MCP79 AHCI
* Link Speed: 3 Gigabit
* Negotiated Link Speed: 1.5 Gigabit
Description: AHCI Version 1.20 Supported
Hardware Overview:
Model Name: MacBook Pro
Model Identifier: MacBookPro5,4
Processor Name: Intel Core 2 Duo
Processor Speed: 2.53 GHz
Number of Processors: 1
Total Number of Cores: 2
L2 Cache: 3 MB
Memory: 8 GB
Bus Speed: 1.07 GHz
Boot ROM Version: MBP53.00AC.B03
SMC Version (system): 1.49f2
All I am looking to do is top out my system hardware wise. I already maxed the RAM and was interested in getting an SSD. Before I do....I need to know why the 'negotiated link speed' is not reading 3gb as well, and if it's something I can correct. If I upgrade to a 6gb SSL and the value still reads 1.5 I'll have wasted my money. Thanks all.
I looked in as many sources as I could find, and didn't see any 'published' link speed for my macbook. I am led to believe that it is 3gb based on the system report. Since my 5400rpm drive cannot physically achieve much less than 1gbs, if what your saying is true (which is sounds to me that you know what you're talking about).
With this understanding, even if a 7200rpm drive can't saturated the 1.5gb, and even if my Macbook data *may* not be able to exceed 3, would it be logical to say that an SSD would gives me 3x the speed if I upgrade? I'm just looking to get the most out of my computer with the current processor and the 8gb of RAM. If it makes the music software, opening/closing programs, reboot, start-up, shutdown and things like that more noticeably 'snappier'. I can be comfortable with the investment.
"The bottleneck is the drive's best-case transfer rate."
I would like to know how to go about determining this. I also need to know if I have to limit my choices to an SSD based on the recommended upgrades for my specific computer:
http://eshop.macsales.com/MyOWC/Upgrades.cfm?&model=353&type=Internal+Drive&sort =pop
or if I can get a discounted one such as this:
http://www.microcenter.com/single_product_results.phtml?product_id=0364781
Speed and compatibility. Before I upgraded to this macbook from my PC, I was chasing incompatibility issues all over the place and got to spend less than 10% of my time actually working on music/video production. If only I had know then what I know now….but that's why I gotta do my homework before buying everything these days

Negotiated Link Speed on MacBook Pro mid-2009 with Kingston SSDNow v300
Hi,
I have a mid-2009 MacBook Pro (13") with Kingston SSDNow v300 SSD drive with Mavericks OS X installed.
I've noticed from different forums that many users have the same problem that I have: SSD drive's Negotiated Link Speed is only 1,5 Gbps, although MacBook Pro mid-2009 should support 3 Gbps speed.
My system has EFI 1.7 firmware update (MBP55.00AC.B03) installed in and System Info says that 3 Gbps Link Speed should be possible:
NVidia MCP79 AHCI:
Vendor: NVidia
Product: MCP79 AHCI
Link Speed: 3 Gigabit
Negotiated Link Speed: 1.5 Gigabit
Physical Interconnect: SATA
Description: AHCI Version 1.20 Supported
Many users have tried to reset NVRAM and SMC and I have also done these steps, but with not any improvement.
Some users have mentioned that MacBook Pro mid-2009 has a poor SATA ACHI chipset (NVidia MCP79) and SATA III SSD drives won't work on SATA II speed unless SSD drive is forced to work on SATA II speed by firmware update or by some tweaking tool. Is there this kind of tool available for Kingston SSDNow v300?
One user says that he got 3 Gbps Negotiated Link Speed on Mountain Lion, but after installing Mavericks, speed dropped to 1,5 Gbps (https://discussions.apple.com/message/23549859#23549859).
So, is there any way to get Negotiated Link Speed to work on 3 Gbps on Kingston SSDNow v300 with MacBook Pro mid-2009 (for example by installing an older version of Mac OS X) or do I have to buy a new SSD drive from another manufacturer to get 3 Gbps Negotiated Link Speed to work on my machine?
If the last option (to buy a new SSD drive) is the only option, would it be wise to look for an older model, a SATA II drive, (maybe OCZ Vertex 2) to get 3 Gbps speed?
Thanks!Hi
I was just as frustated as you after installing the Kingston v300. I mean it's a solidly built drive with the reliability of kingston (I've been using their RAM for years and years in my desktop PC without problems). Unfortunately, for a the last 3 months I had it in my 2009 unibody white macbook, it was stuck at link speed 1.5.
I've been searching in forums since then without any solution. Even the update for bios is not available for my model.
I just tried the SMC reset after reading the blog.
http://thenextweb.com/lifehacks/2010/12/04/how-when-why-to-reset-the-pram-smc-on -your-mac/#!w3XEY
On reboot, everything seemed faster, so I checked the negotiated link speed and it was at 3 instead of 1.5! Yay! Then I checked the disk transfer speed on Blackmagic Disk speed test and it roughly doubled from 138 to 260MB/s. Now, I'm not going to shutdown or restart...
I hope this post is useful for people like me stuck at 1.5 Gbps speed. Good luck -
My hard drive was replaced last week on my macbook pro. The geek squad from Best Buy backed up all my information prior to replacing the hard drive. They reinstalled everything on the new hard drive including iTunes. When I opened I tunes, i had some but not all my songs listed. All my playlists and purchases were missing. I attempted to sync my iPod so my playlist and information would be reinstalled but iTunes does not recognize the iPod to allow it to sync.

Hello, I need help to retrieve deleted information to partition an external hard drive. What should I do?
I'm not about the question, and giving you the right answer requires me to ask a few more questions.
Do you want to retrieve deleted information for future usage, or to completely delete a partition? The latter is straightforward: simply erase the partition. The former is more complicated: it's very difficult, even using available commercial software, to recover deleted information. If the data is important, you may want to contact a professional like DriveSavers. It won't be cheap. -
How can I force Time Machine to make a complete backup of my Hard Drive. I just installed a new external drive for Backup since my previous one failed. Now when I back up, Time Machine only backs up my data folder and the Users folder.
When I start a backup. Time Machine says "Oldest Backup: None; Latest Backup: None", so it seems like it should do a complete backup, but it only does a partial.Hi I'd like to jump in here. Your app showed me this:
Time Machine:
Skip System Files: NO
Mobile backups: OFF
Auto backup: YES
Volumes being backed up:
Macintosh HD: Disk size: 749.3 GB Disk used: 453.81 GB
Destinations:
Plastic Wrapper [Local] (Last used)
Total size: 999.86 GB
Total number of backups: 64
Oldest backup: 2013-07-24 23:25:11 +0000
Last backup: 2013-11-17 01:40:47 +0000
Size of backup disk: Too small
Backup size 999.86 GB < (Disk used 453.81 GB X 3)
Time Machine details may not be accurate.
All volumes being backed up may not be listed.
/sbin excluded from backup!
/usr excluded from backup!
/System excluded from backup!
/bin excluded from backup!
/private excluded from backup!
/Library excluded from backup!
/Applications excluded from backup!
Aside from the size of my backup drive, which I will increase at some point, I'd really like to have time machine backing up all system folders, especially Applications. How to I reset this hidden exclusions?
Thanks,

How can I make a backup to an external hard drive from iPhoto if it won't open?
how can I make a backup to an external hard drive from iPhoto if it won't open? I just wan't to make a backup to my pictures not my entire computer so how does Time Machine work on that?
you could also clone the drive or volume, or just some of the user folders. look for carbon copy cloner, then enable the "use checksum to insure file integrity."
you can have multiple iPhoto Library catalogues in different locations.
Continue to use TimeMachine and make sure it has 350% or more capacity than your system and data. -
I want to upgrade my Hard Drive to 1TB and more.
What is the maximun Hard Drive I can install for a MacBook Pro 2009
Yesterday, I tried a SEAGATE SSHD but my screen was always a showing a QUESTION MARK (?). It's not the cable because when I put back the old original version, everything works...Any sugestion of brabnding or procédure to upgrade my hard drive?The largest 2.5" dia SATA drives available are 2 TB in capacity.
Have you tried the Seagate SSHD connected externally to the MBP via USB? The drive itself may be faulty.
Ciao.
Here is a good place to start looking for a replacement drive:

My macbook pro is still under warranty. I have just put it into Mac 1 to be repaired because I had the folder with the dreaded Question mark on it....new hard drive. I was told that if I wanted my data retrieved, I would have to pay $445 p/h. Ahh!!! Shouldn't that be covered by warranty?
My newest Mac just did the same "folder of death" dance. It's too late for you now, but you might consider a passport backup drive.You can get 2&3 T-bytes now fairly reasonably priced. A given with computers is they will crash, just a question of how bad and when, so you can be prepared for the next time.

Mac Pro not auto-negotiating link speed correctly
We have found that none of our Mac Pros are auto-negotiating their network link speed correctly while running 10.4.10. This happens while booted into the production OS as well as netbooted to a 10.4.10 NetBoot image. The network card can be forced to negotiate at higher speeds either through the command-line or System Preferences but it will not do it on its own. We have gigabit to every desktop and imaging at the default 10 Mbit is horrible! Any help would be appreciated!
There is a kext that is the culprit:
/System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/AppleIntel82 54XEthernet.kext
In 10.4.9 it's version is 1.1.7a3, in 10.4.10 it is 1.1.8a2, in 10.4.11 it is 1.1.8a6
That doesn't matter much really, but that's the details.
1. Get the 10.4.9 Intel Combo Updater
2. Get OpenUp or Pacifist
3. Open the DMG
4. Show contents on the PKG
5. Copy out the pax.gz file to the desktop
6. un-Gzip the pax, and open that up (with Pacifist or OpenUp)
7. Get the old kext
8. Copy it into your /System/Library/Extentions
Now, the permission on the kext need to be changed to root:wheel or if you in Finder system:wheel
Also, you should either delete the kernel caches or:
sudo touch /System/Library/Extensions
this changes the date stamp on the directory and OS X will recreate the kernel caches...
And yes, the 10.4.11 seed update corrects this.
Also bonus Log files! These have been "prettied up" for readability, but you'll see, 10.4.10's driver is just spitting out Zer0s so the network switch/hub has no choice but to say "O K... I ' l l s p e a k s l o w e r t h e n..."
10.4.9:
Auto-Neg Advertise Reg (04d) = 0xde1,
Link Partner Ability Reg (05d) = 0xc5e1,
Gig Advertise Reg (09d) = 0xe00,
Gig Link Partner Ability Reg (10d) = 0x7800
10.4.10:
Auto-Neg Advertise Reg (04d) = 0xde1,
Link Partner Ability Reg (05d) = 0x0,
Gig Advertise Reg (09d) = 0xe00,
Gig Link Partner Ability Reg (10d) = 0x0
(Much Prettier)
10.4.11(seed):
Auto-Negotiation Advertisement Register (04d) = 0xde1
Auto-Negotiation Link Partner Ability Register (05d) = 0xc5e1
Auto-Negotiation Gigabit Advertisement Register (09d) = 0xe00
Auto-Negotiation Gigabit Link Partner Ability Register (10d) = 0x7800
PHY Specific Status Register (17d) = 0xaf48
If this info from 10.4.11 is NDA well bite me, I think people should know it'll be fixed in the future, right? -
Speed up iMac mid 2010: more RAM or bigger hard drive?
My mid 2010 21.5" iMac is getting really slow. granted it only has 4GB of RAM and 500GB of hard drive with barely 10GB left.
So the simple question: do I add more RAM or get a new hard drive to speed up this old baby?tyron1980 wrote:
He has a lot of files so the author should transfer some of his files to an external HD. Its his prerogative choice if he make some sacrifices in order to have bigger space. Once he has enough free space then he can apply doing partition.
I'll try again.
How will making a 2nd partition help this problem, and why would it be needed otherwise.
Here's the answer.
IT WON'T, and there is no advantage to multiple partitions withut specific need for them (multiple OS's for example)
To the OP, please ignore posts from tyron1980 -
Speed up early 2009 macbook5,2 by switching mechanical hard drive to SSD
I am running Mavericks on an early 2009 Macbook5,2 4gb RAM CPU@2ghz Intel core 2 duo. It is running at an unacceptably slow speed. Network performance is very hopeless too. I am wondering if switching mechanical hard disk to a SSD would revive this macbook enough to keep it for a few more years. Please advise if this approach has a chance to improve its performance adequately. If yes, what steps to follow to migrate software on my existing hard drive to SSD?
Your Macbook has a SATA bus.
1. This is what I recommend. Some drives which are SATA 2/3 compliant do not support SATA 1. http://www.amazon.com/Samsung-Electronics-2-5-Inch-SATA_6_0_gb-MZ-7PD512BW/dp/B0 09NB8WTI/ref=sr_1_3?ie=UTF8&qid=1405128604&sr=8-3&keywords=samsung+840+pro
I have used this in SATA 1 systems without any issues (the OCZ Vector is an example of problems with SATA 1).
2. Replacing the drive can be done using these steps - https://www.ifixit.com/Guide/MacBook+Core+2+Duo+Hard+Drive+Replacement/514
3. I suggest you use an external drive and make a Time Machine Backup of your MB, before you make any changes. If you have a Time Capsule, it can help as well (otherwise see if you can find a USB/FW external drive for backup).
4. Once you have a good backup, replace the drive using steps in 2. Take the old drive from the MB and put it in an external SATA enclosure (preferably one that has both USB and Firewire), so it becomes your external boot disk. If you do not want a SATA enclosure, you can also consider a FW only enclosure.
5. You can now boot from the external disk. Restore the TM backup in step 3 to the internal SSD. You will have to format the internal SSD (because it is usually unformatted). FW connectivity will allow you to daisy-chain the TM backup and your external boot drive. The restore also makes your internal drive bootable. All your applications/settings/accounts/passwords will also be preserved this way. You are essentially restoring everything from the old drive to the new drive.
If you need help regarding TM, let me know. -

Hi when I started my intel based imac this morning all I am getting is a folder with question mark in the middle flashing,I have external hard drive with backup,but when run disc utilities it does not show my mac hard drive.hope someone can help.(it's running mountain lion, well it was)
Try starting up your Mac while holding down the Option key. That should prompt the Startup Manager window where you can select the startup disk then click Restart.
The question mark folder indicates your Mac cannot find a system folder to boot from.
A flashing question mark appears when you start your Mac -
How do I make the photos on my external hard drive appear in the iPhoto screen
I recently had my hard drive "wiped" at the Apple store to speed it up. In the process I lost a lot which I am now restoring. Prior to the wipe the photos stored in my EHD appeared in the iPhoto screen by default. I have lost that and don't know how to restore it
Thanx for any help
poppiAre they in an iPhoto Library?
Hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Choose Library'
If not: import them.

Question with installing operating system to my new hard drive
I just ordered a new hard drive for my macbook. I've had no problems finding how to take out the old one and install the new one into my computer, but I can't seem to find information on how to install osx onto the my computer again. Is it as simple as putting in the osx disks or are there others steps that need to be taken for the macbook to recognize my new hard drive?
Drive Preparation and OS X Installation
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
7. Quit DU after formatting has completed. Install OS X.
8. Restore your files from your backup or put your old drive into an external enclosure so you can restore from your old drive.
