X230 upgrading HDD to SSD -- side rails???

Hi all,
Just got my x230 today, and was planning on replacing the HDD with a Samsung 840pro.
However looking at the manuals from Lenovo, it appears that the HDD has rubber rails and the solid state drive is supposed to have spacers.
Do I need to get the SSD-type spacers, or can I just use the rubber rails that are currently in the laptop?
If I do need them, how do I get them?  I can't seem to find them on the accessories list.
@Lenovo: any official word on this?
Solved!

Thanks Bill.
For the sake of future upgraders who might share my worries ...
Yes, they fit just fine and the machine is running great.

  • Upgrade HDD to SSD (Do i need to re-install?)

    I just bought an SSD (Samsung 470 series is the one thats best with MBP right?) and i want to replace it with the stock HDD that came with my 2011 MBP 13".
    What if i upgrade RAM from 4GB to 8GB and transfer from HDD to SSD by carbon copy cloner. Do i need to re-install Lion then?
    Is TRIM automatically enabled if i transfer from HDD to SSD?

    Upgrading the RAM is fine by itself. Just know you only have two slots, and thus need matching pairs of 4GB modules to increase the RAM from 4GB to 8GB. If you have $900, OtherWorld Computing has 16GB of RAM (two 8GB modules) for sale. (no compensation)
    Use the online Crucial checker and MacTracker to make sure your getting the correct specs of the RAM (and the amount of modules) before purchasing.
    What you need to do is use the free to use (donations accepted) Carbon Copy Cloner on the HDD while it's still in the machine, clone to a external powered drive and hold option to boot from it, test it out that it works.
    Then make the HDD to SSD switch and option boot from the clone again, format the SSD HFS+ Journaled and use CCC to clone it onto the SSD.
    OtherWorld Computing and iFixit has videos, pictures, instructions and tools needed.
    When you clone, it clones the OS X partition only, not both your OS X partition and the Lion Recovery Partition, which in your case is unnecessary to have if you have a "hold option" bootable clone. (should keep two at times)
    If you need to download Lion installer again, simply use MacAppStore and hold option and click on Purchases, either in Lion or Snow Leopard and then make a couple of " hold c" bootable DVD's from these instructions.
    http://www.eggfreckles.net/notes/burning-a-lion-boot-disc/
    These DVD's made from these instructions contain the full OS X Lion, not a Recovery Lion disk or the Lion Recovery Partition which Apple provides a download for and requires a lengthily Internet connection to download Lion before it's installed.
    Far as setting the TRIM, I don't know about that. Hopefully someone else will answer.
    If not ask Dave (Bmer) over here:
    http://macosg.com/
    He replaced his hard drive with a OCZ Vertex, the fastest SSD's on the planet and also his Superdrive with a 7,200 RPM 750GB drive for storage (note: you can't boot from a Lion/Snow/Windows DVD from a external optical drive) so he would know best what to do.
    Also OCZ just came out with a 480 gb or so very fast SSD, the Vertex 3 series, just as fast as the smaller SSD's but with more storage capacity, so that would be worth checking into. (smaller SSD's are faster, larger older ones are just a bit faster than a regular hard drive)
    Also check out your Mac model's SATA number using the fre MacTracker and System Profiler, this way you can by the right SSD for the price and know your bus speed limitation accessing the SSD.
    Good luck.

  • Steps in upgrading HDD to SSD on Macbook Pro 13 Mid 2009

    I need help in upgrading the RAM and Storage in my MacBook Pro 13" Mid 2009. I have bought 8GB Memory and 512 GB SSD from Crucial.com. I have watched a lot of Youtube Videos on how to install them but I am afraid I am still missing some things I need to do.
    I have created a back up on an external drive and have been updating it regularly. I have also created a back up on Time Machine (I think I did).
    Is there anything else I need to do? How about the OSX? Do I need to create a back up for it? Or is it part of the back up I have on an external drive?
    Please help! Thank you.

    " I have also created a back up on Time Machine (I think I did)."
    Check this out:
    http://macintoshhowto.com/repair/back-up-computer.html
    Once you think you've done it correctly restart and hold down the option key or go to "System Preferences" under the Apple and look at "Startup Disk".
    That will tell which Disks are bootable.
    Now about that Crucial drive:
    http://forum.crucial.com/t5/Crucial-SSDs/512GB-M4-and-2009-Macbook-Pro/td-p/7805 6
    It's not clear to me that this issue was resolved. The last post goes nowhere!
    I always use OWC:

    Just did two including this MacBook Pro early 2011 13" and a 2012 Mini. Total no-brainer! The way I like it.

  • W530 HDD/SSD detailed RAIL/TRAY info request

    My apologies as this may appear to be beating a dead horse.  However, I have called Tech support twice, Boulder IBM parts twice, and Lenovo Inside Sales twice.  Sales & this site were the most helpful. 
    I'm posting this as there seems to be some data/info missing as to what some of the parts are comprised of and their specs.  I need this data so I can order the final upgrade parts from either IBM, newmodeus, or ?.  I'm also hoping this thread will help other people who are in the same boat as I am which is ordering parts prior to receiving the PC.
    I'm attempting to do what appears to be the standard W530 main drive bay 500GB 7200 rpm HDD move to a 12.7mm Ultrabay and then insertion of a SSD into the main drive bay.  I will be inserting a OCZ 9.3mm Vertex 4 256GB SSD in the main drive bay.
    From the forums, the Lenovo web site, sales, and IBM parts I've attained the following info.
    A) It appears that the main drive bay will hold up to a 9.5mm drive.
    B) The W530 could ship with either a 7mm or a 9.5mm 500GB 7200 RPM HDD.
    * What's relevant with this is there must be two different rail options shipped from IBM, 7mm & 9mm rails to fill the main drive bay. *
    C) Lenovo P/N 0A65623 = the proper 12.7mm Ultrabay adapter for the W530 due to the larger notebook form factor.
    D) From Sales, there are 2 sets of rails available/recommended for the 12.7mm Bay:
          IBM P/N 04W1640 = COVER (Rubber Rails for a HDD)
          IBM P/N 04W1641 = SSD SPACER (Hard Spacer Rails for a SSD)
          * Concerned that these may not fit the Bay properly or be the correct parts. *
    E) From Sales, IBM P/N 41V9756 = RUBBER SHEET FRU (Rubber Rails for SSD or HDD in the Main Drive Bay)
    * Are these rubber rails for a 7mm or a 9.5mm drive natively? Does this kit contain a caddy tray? *
    F) newmodeus Model TP-60 = a metal caddy tray, 4 mounting screws, and two rubber rails. The rubber rails are supposedly the same as IBM P/N 41V9756.  Website link below:
    http://www.newmodeus.com/shop/index.php?main_page=product_info&cPath=2_7&products_id=218
    I've read the threads and have seen where people shim and cut the rubber rails depending on the drive size.  No offense intended but I want to install the correct and perfectly sized config.
    I'd like to buy genuine parts so I'm really trying hard to make use of the above IBM parts.  The questions below will help me decide on what my SSD mounting config should consist of.
    Unfortunately, I can't seem to find the following info anywhere.
    1) Do any of the IBM rail kits listed above in D & E come with a caddy tray & screws?
    The newmodeus TP-60 does so I am concerned a tray and screws are needed for a proper tight/secure fit.
    2) Do either of the stock Lenovo 500GB 7200 RPM HDD drives ship installed with a caddy tray, screws, and rubber rail config in the main drive bay?  If no, what is the config?
    3) Is the intended Lenovo design, to always use a caddy tray and rails?
    4) Has anyone purchased a W530 with a SSD in the main drive bay and if yes, did it have a caddy tray attach for use with its rails?
    5) if a SSD was initially purchased, did it ship with just the hard SSD SPACER rails and no tray?
    6) If someone has purchased the IBM rail kits, do all three of the kits have the same outside height dimensions?
    7) Does anyone have these dimension(s)?
    8) Has anyone taken their stock 500GB 7200 RPM HHD and rails/potential caddy tray out of the main drive bay and just plopped it into the 12.7mm Bay?
    9) If yes to question 8, is it a perfect tight/snug fit without any gaps, space, or room to jar loose?
    * Concern here that the 12.7mm Bay is bigger and the locking mechanism on the bay will not provide a tight fit. *
    Sorry for all the questions and the above novel.  If it were easy, we'd either be monkeys or paying Lenovo for the integrated parts.  
    Hoping I can just port the existing HDD/rails/tray over to the Bay.  Then it's a matter of how my SSD should be mounted in the  inside of the main drive bay.
    ANY help, to any of the above comments or questions would be greatly appreciated!!
    This has been really frustrating not being able to discover the config.  It seems like it should be really simple... How big are both bay demensions, what are the outside dimensions of the rails, what is the inside config of the rails in terms of drive size dimensions, and are we supposed to use caddy trays all the time with every drive or just a HDD or none at all...  I was REALLY expecting tech support to know this.  Instead, I had to teach them...  They said the PC was new...  
    I'm expecting the PC this week along with the SSD and some RAM.  I'd like to have they correct rail and caddy tray, if needed, here and ready to go.  Need to get this puppy staged and ready to go so I can hit the ground running.
    Cheers & Thanks!

    Thanks harrisb!
    Your solution makes sense.  I found the newmodeus bay after my bundled purchase of the W530, the 12.7mm Bay and the MiniDock.  Also found this forum after the transaction.  It's a shame but it really seems like the Lenovo Bay is making this more difficult than it should be due to the lack of info.
    Unfortunately, UPS is delivering my Lenovo Bay and Dock today.  The SSD and RAM has also shipped and is due to arrive this week as is the W530.
    The only thing that hasn't been purchased is the SSD and HDD mounting gear.
    With this info what would you or anyone else do at this point?
    Would purchasing the newmodeus TP-60 Tray, Screws, and rails work with the SSD in the Main Drive bay?
    Would the HDD and it's default rails/tray fit perfectly/securely in the 12.7mm Bay?
    Would the kit that comes on the HDD still work on the SSD in the Main Drive and then use the newmodeus TP-60 kit on the HDD in the Bay?
    There's also the IBM parts?  Just concerned they don't come with the tray or screws.  And, they won't fit securely in the main drive or bay.
    Really appreciate the speedy reply!!  
    P.S. Got the OCZ due to the great IOPS specs.

  • I have a hdd from late 2009 that I upgraded from leopard to snow leopard to lion to mountain lion.  I want to upgrade the hdd to ssd.  Do I need to buy a new copy of mountain lion to install on the ssd?  If not, then what is the procedure to transfer?

    I have a hdd from a late 2009 mbp.  I upgraded from leopard to snow leopard to lion to mountain lion.  Now I want to upgrade to a ssd.  Do I need to purchase a new copy of mountain lion to go on my new ssd? If I don't, then what is the procedure to transfer mountain lion with my 4 user accounts onto the new ssd from the hdd?
    I'm confused on if I can use the recovery hd on a thumb drive to install mountain lion on my ssd.  Will it be pheasible with so many OS X upgrades?  And then how do I get my user accounts onto the ssd from the hdd.  Do I use migration assistant?  Do I need to make a time machine backup first?  Should I use something called Carbon Clone or something like that?
    Thanks for reading

    If you have a cable that connects and external HDD to the MBP, it will do.  If it is something like this, an  enclosure will not be needed for the swap:
    An enclosure allows you to use your old HDD for storage or backup purposes.  The cable will not. 
    Here are instructions as to how the swap can be performed using DISK UTITY.  Substitute You cable for the enclosure in same:
    INSTALLING A NEW HDD IN A MBP
    1. Make certain that you have backed up all of your important data.
    2. You will need a HDD enclosure.  One with a USB connection will do.  A 9 pin Firewire is better.
    3. Install your new drive in the enclosure and connect it to your MBP.
    4. Open DISK UTILITY>ERASE.  From the left hand column drag the new drive into the 'Name' field.  Make sure that the format is 'Mac OS Extended (Journaled)'.  Click on the 'Erase' button.
    5. Click on the 'Restore' button (on top).  Drag the old drive into the 'Source' field and the new drive into the 'Destination'  field.  Click on the 'Restore' button on the bottom right hand corner.
      Depending upon the amount of data you are transferring, this may take a couple hours or more.  A Firewire will speed up the transfer.  This will result in both drives having identical information on them.
    6. After the data transfer has completed, you may swap the drives.  Start the MBP and you have finished the installation.  The initial boot may take a bit longer than you are accustomed to, but that is normal.
    7. When you are satisfied that the new hard drive if functioning properly, you can erase the old drive and use it for any needs that you may have.
    If there is any confusion on your part, post back.
    Ciao.

    Turn the Mac on (or reboot it) and press command-option-R as soon as you hear the startup chime. Hold the keys down until you see a globe, then release. When the Recovery Menu appears you choose Disk Utility and format the SSD for use in a Mac (Erase>Set Format to MacOS Extended (Journaled), then exit Disk Utility and choose Install OSX
    You will need to be connected to the Internet and your Mac should detect your network and ask for a password automatically when Recovery Starts.

    Where do you live? Country only, please. I have heard that HP Service Centers will perform memory and SSD upgrades on these "closed" systems but I am not sure where all of them are located or what they would charge. You should be able to find a competent local computer shop to do it. It does put the warranty in jeopardy but the warranty will not be revoked if the job is done properly, without damage to the laptop.

    At the same time please can I upgrade the RAM to 16 GB DDR3L? which is the Maximun RAM Upgradable?
    Best regards

    Hi, Christian:
    Yes, if you replace the hard drive or memory, the warranty will be voided as neither component is a DIY (do it yourself) project.
    Please see the service manual at the link below, chapter 6 for the authorized service center removal and replacement procedures for those components.

  • IdeaPad Flex 14 HDD to SSD upgrade

    Hi!
    I have the Lenovo IdeaPad 14 (US version) with a hybrid drive Seagate SSHD Thin (500GB HDD + 8GB SSD). I want to upgrade to an SSD and dual-boot with Ubuntu 14.04. My main issues are the following:
        - Is the HDD user replaceble? Would I be voiding my warranty if I open my laptop?
        - Can I use the mSATA and SATA to put two drives and dual-boot between them? Would the BIOS/UEFI allow me to do so? (I haven't previously worked with mSATA drive and I don't know how they are recognised by the motherboard or how they appear in device manager)
        - How do I safely transfer my Windows 8.1 installation from the old SSHD to the new SSD in order to keep my files/settings and most importantly my Windows license?
        - While I'm at it, why not upgrade the RAM as well. So does the laptop have one or two slots for RAM as I couldn't find any specs/service manual online?
        - Where do I find a service manual in order to know how to properly disassemble the laptop?
    If anybody knows the answer to any of these, please write/post a link here. It will be much appreciated!
    Thank you!

    Once the screws are removed under the angular feet the back comes of the laptop.
    Glad you've been able to have the confidence to get the back of the laptop. I guess you thought what I thought, the base inards will fit anything from 13.3" to 15.6 using little more than different length ribbon connectors. Fitting it in a 11.6" device may be possible although the hard drive may have to SSD.
    I find it hard to believe you need to remove 24 screws to remove the HDD, and 24 to go back afterwards. Had a play with Ubuntu 14.04 using VMWare player myself, although for some stupid reason it didn't prompt for a user and password during the install leaving me only able to use the guest account to log in. I clearly need 8GB of RAM and an SSD to make a smoother VM experience of Ubuntu and another VM install to save my settings.
    Certainly worth taking the back off to have a look.

  • Should I upgrade RAM or HDD to SSD on my Mac mini mid 2010?

    Hello,
    I have a mid 2010 Mac mini with 2GB of RAM. My apps like E-Mail, Safari, Google Chrome and others are starting slow and sometimes running slow. Should I upgrade RAM to 4GB or 8GB or replace my 320GB HDD to SSD?
    Thank you yor help, DZetko

    You are running a Core 2 Duo. Even a duck has paddling limitations. You are running Mountain Lion on a 2GB machine and it is starved for RAM. The performance is gravitational.
    Upgrade your machine via the preceding MacSales link to matching 4GB modules for 8GB. I believe you will be astonished at the improvement. Make certain that you have used Disk Utility to verify/repair your system preferences, and then verify the boot drive while in Disk Utility.
    In your login directory (~) go into the Library/Caches folder, select everything in it and move to Trash. Don't bother to empty the Trash just yet. Shutdown your mini.
    Now, power on your mini. At the chime, press and hold the shift key until you see a grey horizontal progress bar. At the login window, press and hold the shift key again as you press the right-arrow icon to login. Release the shift key when the Finder menu bar appears. You are now in Safe Boot Mode. Empty the Trash. Reboot normally.
    This just did a series of house-cleaning steps for you. It removed and/or rebuilt system cache files, including the Fonts cache. It also rebuilt the database governing the open with ... menu. So, if you had any duplication in there, they are repaired. Safe Boot Mode also does a low-level inspection of your boot drive. You should see some additional performance improvement. I do a Safe Boot Mode about once a month as routine maintenance.
    With the improvements I have suggested and preceding pointers, you should have a 2010 Mac mini working as well as it can with Mountain Lion and a SATA II hard drive.

  • New Model: HP Envy 15t Upgrade HD to SSD or mSATA SSD?

    Hello Everyone,
    I have been reading several threads on upgrading the HDD to SSD and it seems like everyone has been successful in doing so.  My question is, is there a benefit to upgrade the HDD to a SSD or to just add in mSATA SSD?  I currently have a networked drive that holds most of my data such as music, pictures, and videos so I do not believe I need more capacity on my hard drive.  With that being said, I planned on buying a 256/240GB SSD drive, it is just a matter of which one do I purchase? a regular SSD or mSATA SSD?  Thoughts?  Comments?  Concerns?

    on a side note:  I have the new Envy 15t...I really wished they would have changed the model name to something completely different since the prefix is the same as their old model...stupid....

    Get a regular 2.5 inch SATA SSD. Very slightly slower than an mSSD but still way faster than anything else. Trying to configure the mSSD as boot drive is a huge hassle. 

  • Changing HDD to SSD, what are the options?

    hi, guys, new to the forum, I just bought a thinkpad x130e during an on sale event at one of the local retailer, pretty excited, since i like the rugged design.
    I am looking at an upgrade from 320G HDD to a 128G SSD... but i don't have any windows 7 installation disc handy, so what are the options for me to install the operating system (windows 7).
    I don't know if there is a way to transfer the whole system from HDD to SSD? will there be any trick to perform? or simply i just have to purchase new copy of windows?
    cos i noticed i do have a windows7 pro product key at the bottom of my thinkpad, i kinda don't want to waste the money.
    please help..
    Solved!
    Go to Solution.

    You don't need to purchase another copy of Win7. You will need
    1. SSD. This must be 7mm thick, not the more common 9.5mm thick.
    2. USB enclosure for your HDD,
    3. Software to "clone" the contents of your HDD to your SSD. Acronis True Image is a well-regarded package that does this. There are also some free utilities that can do this, however, I'm not familiar with them.
    Procedure:
    1. Move the HDD to the external enclosure.
    2. Put the SSD in the X130e.
    3. Reboot from the HDD. (You'll need to interrupt boot with Blue ThinkVantage button to specify.)
    4. Install Acronis (or equivalent.)
    5. Perform disk clone operation. You will need to tell the software how you want to resize partitions since you're going to a smaller disk.
    6. Reboot from SSD.

  • Cloning Hdd to SSD boot drive and what happens with Music/Logic Plugins

    Hi, my computer is a mid-2012 Mac Pro 12 Core
    It's a great computer but I'm considering upgrading my main boot drive (WD Caviar Black 1TB HDD) to a 1tB Samsung EVO 840 SSD drive (I'm using a sonnet tempo PCI card to mount an SSD that holds audio at the moment and will add another SSD for the boot drive I'm referring to) so I just had a question - if I clone the HDD to the new SSD, what happens with things like licenses for my audio plugins, such as Native Instruments Komplete, programs by IKMultemedia. programs that use an ILOK such as Steven Slate Plugins and also, WAVES plugins?  Will this info all carry across to the new SSD drive or do you think I'll need to reauthorise some things?  I have all the serials etc so this shouldn't be an issue, but just wondered.
    Any help would be appreciated as it feels like quite a big step in that it's my main system drive!
    Thanks in advance

    CCC is excellent. If it doesn't work then sure, just always have a safety net of your system that is untouched.
    Also, after a clean install, CLONE it!
    And then use Setup Assistant. Migration Assistant.
    Clone of the system can go on sparse disk images too so you don't have to partition (should have at least one though) and you can have clone from different stages and versions: 10.9.4, without Setup Assistant, migrated, full loaded with all your apps. Multiple versions.
    CCC is designed to make a working bootable copy of a system so you can move the system to another boot device like hdd and SSDs without the worry.
    But I think we were talking about a system that did not see a clean install of Mountain Lion or Mavericks so it is over due for one!

    Super thanks If you don't mind losing OneKey feature you can just buy an ssd similar to this which I think includes a cloning software which you will use to transfer your OS to the ssd. In general all ssd nowadays already have trim integrated and enabled.
