Does SSD Trim work at disk or partition level?

Trim is enabled on my MacBook Pro (About this Mac etc), but the HD has a Bootcamp partition on it.
My belief is that the Bootcamp partition is not being trimmed...is this right? (Would love to be wrong)
As I understand it Trim in Windows 7 can only be enabled in AHCI mode and enabling AHCI seems difficult. Has anyone done it and got Trim working on a Bootcamp partition.

<br>No. On the 101 page "30 Clear Page(s) Cache     Clear Cache for all Items on Pages (PageID,PageID,PageID)" is the last process. But we do some db logging in db (IP, user logged).

<br>
<br>I see on forum that there are many points on that. We are receiving only that error. Shouldn't be after that some ORA...like:

  • The startup disk does not have enough space to be partitioned

    I have a custom upgraded Mac Mini (from 1.6 Core Duo to 2.33 Core 2 Duo & 64GB SSD - a fast little machine!) Under Leopard 10.6.6 & could create a BootCamp partition. Now after a reformat & upgrade to 10.6.7, BootCamp reports, "The startup disk does not have enough space to be partitioned". BootCamp says it needs 10 GB free space. The Finder says there is 23.4 GB available.
    Has anyone else run across this?

    Backup. Format. Restore.
    Windows 7 needs 40GB+
    HFS needs 20GB/20% free space to function.
    64GB is fine -- but just one OS, not two. 
    you might squeeze OS X into 30GB if you move and trim a lot.
    Windows 7 SP1 32-bit - the updates take 9GB of space (temp) on top of 20-25GB plus you'll need to disable page, hibernation, not install programs, and leaves little for TRIM and Garbage Collection.
    When Windows gets too low, you can be blocked from login or runnng.

  • Can a use a partitioned external hard drive to create a disk image? I tried, doesn't seem to work using disk manager.

    Can a use a partitioned external hard drive to create a disk image? I tried, doesn't seem to work using disk manager.

    OK, it's very bad computing to use a backup disk for anything but a backup. The reason being is if/when the HD crashes you will have lost not only all your backup but the data files. While I commend you for wanting redundant backup, you really need separate EHDs for doing so. Format each EHD using Disk Utility to Mac OS Extended (Journaled) using the GUID parttition. When you connect, OS X will ask if you want to use that drive as a Time Machine backup drive, select yes and then let it backup. On the second EHD format the same way however do not use TM as a backup, this time I'd suggest an app such as SuperDuper or Carbon Copy Cloner to make a clone of the internal HD. Leave both EHDs connected and TM will backup new or changed files automatically on a hourly basis. The clone you will need to set to backup on the schedule you want. For example I have my SuperDuper EHD set to backup only changed or updated files at 2AM every day.
    The advantage of a clone is that if the computers internal HD crashes you can boot from a clone and continue working, TM will not do that but it's great for keeping an archive of all files. So if you want a version of a file from many months ago, TM will help you locate and restore it.

  • I'm getting this error with bootcamp "The startup disk does not have enough space to be partitioned"

    Here's the story...
    I had a dual boot configuration on my mac with Mac OS X Lion and Windows XP (made with bootcamp).
    I decided to reinstall windows.
    I deleted the windows partition using BootCamp.
    Tried to recreate the Windows partition with Boot Camp and got: "The startup disk does not have enough space to be partitioned  You must have at least 10 GB of free space available"
    After reading several posts on this forum I decided to defrag the hard drive and try again. 
    The defrag did not work and I'm still getting the error, I have 22 gb of free space on my drive.
    Any suggestions?
    Also, I tried repair disk and repair permissions
    Hmm, my external harddrive says on the box "OS X 10.5.8 or higher (32-bit kernel only)"  Could the 32-bit requirement be an issue? Is lion 64-bit?

    Boot Camp must be able to allocate a contiguous block of space on the drive. If it cannot find 10 GBs of contiguous space, then you cannot create the Windows partition.
    You will have to backup your OS X partition to an external drive, boot from the external drive, use Disk Utility to repartition and reformat your hard drive back to a single volume, then restore your backup to the internal hard drive.
    Get an empty external hard drive and clone your internal drive to the external one.
    Boot from the external hard drive.
    Erase the internal hard drive.
    Restore the external clone to the internal hard drive.
    Clone the internal drive to the external drive
    Open Disk Utility from the Utilities folder.
    Select the destination volume from the left side list.
    Click on the Restore tab in the DU main window.
    Check the box labeled Erase destination.
    Select the destination volume from the left side list and drag it to the Destination entry field.
    Select the source volume from the left side list and drag it to the Source entry field.
    Double-check you got it right, then click on the Restore button.
    Destination means the external backup drive. Source means the internal startup drive.
    Restart the computer and after the chime press and hold down the OPTION key until the boot manager appears.  Select the icon for the external drive and click on the downward pointing arrow button.
    After startup do the following:
    Erase internal hard drive
    Open Disk Utility in your Utilities folder.
    After DU loads select your internal 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.
    Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.  Do not quit Disk Utility.
    Restore the clone to the internal hard drive
    Select the destination volume from the left side list.
    Click on the Restore tab in the DU main window.
    Check the box labeled Erase destination.
    Select the destination volume from the left side list and drag it to the Destination entry field.
    Select the source volume from the left side list and drag it to the Source entry field.
    Double-check you got it right, then click on the Restore button.
    Destination means the internal hard drive. Source means the external startup drive.
    Note that the Source and Destination drives are swapped for this last procedure.

  • Disk does not contain a Windows XP-compatible partition

    Hi,
    I've just received my new Mac Pro and I tried to install boot camp, in boot camp assistant everything seems all right, i choose the main this, choose a partition of 31Gb to boot camp it creates well to, as to insert the WINXPSP2 CD, and then restart.
    When I'm on the screen to choose the partition to install winxp, i choose the right one that Boot Camp have created, but then this screen appears.
    "To install Windows XP on the partition you selected, Setup must write some startup files to the following disk:
    238473 MB Disk 0 at Id 1 on Bus 0 on atapi [MBR]
    However, this disk does not contain a Windows xp-compatible partition.
    To continue installing Windows XP, return to the partition selection screen and create a Windows XP-compatible partition on the disk above. If there is no free space on the disk, delete an existing partition, and then create a new one.
    To return to the partition selection screen, press ENTER."
    Any one have any ideas?! I tried to find some info in this forum and google but i didn't find any answers.
    Regards to everyone.
    Marco

    Why not just create a 2nd drive and leave your OS X boot drive well enough alone - makes life easier.
    Format as MBR and one or more partitions as MSDOS and boot from XP again.
    Might want to try erasing your current partition (still MSDOS/FAT) and try again.

  • "The startup disk does not have enough space to be partitioned?" WHY!??

    I"m trying to intall windows 7 on my Macbook air  OS X 10.6. When i enter bootCam i get this error "The startup disk does not have enough space to be partitioned" . It says I need 10GBs of free space, even though I have 500GBs of free space on my drive external hardriver.
    I did my research, and a lot of people are saying to use idefrag and defrag the hardrive, which i did. I also verifed disk permissions and repaired disk permission and all the other stuff.
    What should i do? Apple hass the shittiest service. I spend $1100 bucks for something and i don't even get support without paying? to me, that's BS. so if anyone could help i would greatly appreciate it.

    Thanks Bob.

  • "Start-up disk does not have enough space to be partitioned"??

    Hi there, I hope someone can help.
    I've been using bootcamp for a couple of years but recently it has started to play up so I decided to reinstall a fresh. I went into OSX and ran "boot camp assistant" and deleted the partition and start again. For some reason when I try to go though "bootcamp assistant" to set up windows xp again I get an error saying "Start-up disk does not have enough space to be partitioned - You must have 10g of space available" But I check my space available I have 23.5gb free. It's driving me nuts! :/
    Cheers, Mark

    It's possible that your drive is sufficiently fragmented that Boot Camp Assistant cannot allocate enough contiguous space to set up the partition. It's also possible that it's simple a directory issue. I would start with repairing the hard drive:
    Repair the Hard Drive
    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. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then quit DU and return to the installer. Now restart normally.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    After restarting per the above try using Boot Camp Assistant to allocate a partition. If it still complains then you will need to defragment the drive. You can do that as follows:
    A. Clone using Restore Option of Disk Utility
    1. Open Disk Utility from the Utilities folder.
    2. Select the destination volume from the left side list.
    3. Click on the Restore tab in the DU main window.
    4.Check the box labeled Erase destination.
    5. Select the destination volume from the left side list and drag it to the Destination entry field.
    6. Select the source volume from the left side list and drag it to the Source entry field.
    7. Double-check you got it right, then click on the Restore button.
    Destination means the external backup drive.
    Source means the internal startup drive.
    B. Boot from the clone.
    Restart the computer. After the chime press and hold down the OPTION key until the boot manager screen appears. Select the icon for the external drive and click on the large downward pointing arrow button.
    C. Use Disk Utility to erase the internal hard drive.
    D. Restore the clone to the internal hard drive.
    1. Open Disk Utility from the Utilities folder.
    2. Select the destination volume from the left side list.
    3. Click on the Restore tab in the DU main window.
    4.Check the box labeled Erase destination.
    5. Select the destination volume from the left side list and drag it to the Destination entry field.
    6. Select the source volume from the left side list and drag it to the Source entry field.
    7. Double-check you got it right, then click on the Restore button.
    Destination means the internal drive.
    Source means the external drive.
    *Note that the Destination and Source drives are reversed when you restore the clone from when you made the clone.*

  • Cannot get brand new hard drive to work. Disk utility states operation not supported when I try to erase or partition?

    Without any success, I cannot get my hard drive to work in disk utilities. I am able to see the disk in the upper left hand column, but when trying to initiliaze the software always reads operation not supported. Any ideas?

    You probably have too new a hard disk.  Contact the hard disk manufacturer and ask what jumper setting is needed to drop to 1.5 Gbps SATA speed.
    Either that, or return the disk, and go to http://www.macsales.com/
    They can be sure to equip you with a proper hard disk.
    Note formatting is key as well:

  • SSD always disappearing and unable to partition/format

    Hello,
    i recently bought a Samsung 840 EVO 500GB for my 27" iMac 2011. It worked great at first, installed OS X, then used Bootcamp for installing Windows 7. But when i used the Windows installation to format the BOOTCAMP partition, the SSD suddenly disappeared. Booting OS X didn`t work either after that.
    I`m quite desperate right now, i`m unable to partition/format/analyse or repair the SSD. When i boot up my iMac the SSD is listed in disk utility. But as soon as i try anything, the tool freezes for about 30sec and answers with an error. Then the drive disappeares and won`t show up again until i reboot my iMac. I have tried using different computers (Mac, Windows, Linux) and several tools, but i get the same behaviour over and over again.
    Right now i`m suspecting a defective drive, but i`m still hoping for a quick fix. Anyone experienced something like that?

    Yes of course
    Read and Write speed are about 500-520 MB/s. Both on OS X and Windows. Btw. my iMac has the 250GB version and my PC got the 500GB version installed (for games). TRIM is enabled.
    It`s quite a fast drive. At work, i`m using a MacBook Pro Retina, and the speed of that flash drive tops at about 350 MB/s.

  • SSD Trim and recovery software

    I have a crucial MX100 512G ssd and I know the windows 10 SSD optimize tool is SSD trim. However, after I ran the SSD optimization showing 100% trimmed, I noticed the trim didn't work because I could still recover my deleted files via data recovery software ( such as disk drill and others). Does it mean TRIM function will not wipe the block unless I do secure erase on the SSD, and people can still recover their deleted files even the SSD has TRIM function?  I thought if SSD has TRIM, deleted data could not be recovered. ( I even left the computer idle over night, and I could still recover the files I deleted). 

    dummykid, have you checked files integrity after the recovery? That is, for example, if you have recovered .jpg file with a photo were the photo viewable?
    The main function of TRIM is not to make data unrecoverable. Making data unrecoverable is a side effect of TRIM, one could say. 
    When a file is deleted from the drive the space it used to occupy should be TRIMmed and usually it occurs very fast. Recovery tools however, can still usually find the file with its name and attributes (size). This is because some data about old/deleted files can still be left in MFT (master file table) area.
    When you delete data from the drive TRIM sends information to the SSD controller to help it clear the corresponding NAND parts. But I belive that the MFT works the same way with or without TRIM, that is it still stores some data related to deleted files, like name and size. But it is file content you really want to recover, not the file name and attributes only. Recovery tool will find the name and attributes of the file and it will recreate that file with the data taken from the drive, but the data itself can be completely different from the original or even empty. Check that out!
    On my SSD I can 'recover' many photos (.jpg files) but they are unreadable, some of them have some random data and some have no data inside.

  • Hardware: SSD drives and scratch disks

    Hi,
    I am building a new system for Photoshop. Two quick questions:
    1. I note in Adobe's system reqs it says Photoshop cannot be installed on flash-based storage devices. Does this include SSDs? Is there a genuine problem here (i.e. if my application drive is an SSD the PS won't work)?
    2. I have not previously had a so-called "scratch" disk so I don't really know what it is or whether I need one, or more than one. What's the general advice here? - separate drive to the PS application drive? also separate to the Windows drive? How big? Will an SSD be a good choice for a scratch drive?
    Thanks in advance,
    Alastair

    G'day,
    In answer to your query SSDs work fine to install cs4 on bar the following I'm having.
    I've built a new system using ssds.and is working fine bar one problem
    Specs of the system is
    I7 920 cpu, Asus P6t se mb, 12gb ram, 128gb ssd, 64gb ssd, 4gb raid 1+0 array onboard, nvidia geforcegtx260. I use the 128gb ssd as the os and programs drive. The raid is the data drive. All works brilliantly except when I set the 64gb ssd as the scratch disk the following happens
    "Could not open a scratch file because the file is locked.  Use the 'Properties' command in the Windows Explorer to unlock the file."
    I hit OK and get this error -
    "Could not initialize Photoshop because the file is locked. Use the 'Properties' command in the Windows Explorer to unlock the file."
    Pressing ok then shuts the program and I need to reset cs4 prefernces and then it all works fine. OS is Win7 64 bit.
    Now I have just got to try and fix this problem Anyone got suggestions?
    Cheers
    Onslow
    Hmm, seems to have stopped doing this now after resetting the scratch to the ssd and then rebooting. All is now fine and wonderfully quick.

  • I am running OS X Yosemite on my four year old MacBook Pro which has become progressively slower and is loaded with applications I no longer use. I plan to start afresh by formatting a new 1TB SSD as a boot disk and reinstalling Lightroom 5 and PhotoShop

    I am running OS X Yosemite on my four year old MacBook Pro which has become progressively slower and is loaded with applications I no longer use. I plan to start afresh by formatting a new 1TB SSD as a boot disk and reinstalling Lightroom 5 and PhotoShop CC.
    Is there a list of the files and/or folders that contain Settings and Preferences which can be copied from the old system to the new?

    with your cc apps you should try to use the sync feature.  that's never worked consistently for me, but when it does work, it's helpful.
    there are preference folders and presets and settings that you could copy but you're better off installing fresh because a common problem for people with adobe program issues is a settings issue.

  • Help needed.. Changed HD, 'broken' DVD reader, working recovery disks.. how to?

    Hello all, hope someone can help me here. I have a Toshiba Satellite p300-19f, win vista 32 in dotation. 
    Long story short, the computer has served me well for roughly 3 years now. All at a sudden, on startup when on windows charging page (with win logo and green counter going up), it started freezing. 
    I tried recovering last working win configuration, I tried recovering precedent backup points, at times I solved until the problem randomly showed up again (same identical problem), so ultimately I formatted and re-installed fresh vanilla version from recovery partition succesfully. Problem went away, until it came back. (all of this in 1 month time span)
    It worked ok for a couple weeks, and started giving the same problem again. Ultimately I figured out (I immagine) that the hard drive must have some problems, as this freezing on windows startup (immediately distinguishable as the cpu stops working / the light in front stops twinkling) occured basically randomly, regardless of software installed in the pc, or time since last format.
    I decided to change the hard drive, but obviously have the problem of the new operating system. My dvd burner is broken, or at least does not work reliably. I got an external sony burner and through the toshiba disk creator applet made the recovery disks (2 DVDs) successfully.
    I changed the hard drive, tried to reboot and reistall using in laptop dvd, when it gets to copy the first big file it gives a CRC error, an aborts the whole thing (sending me to a prompt of commands though.. where I copied the whole content of the DVDs on the just made HDDrecovery folder in v: through the recognized usb external burner, but the computer failed to recognize on later startups).So I tried to boot it up with the recovery disks in the external burner (bios DOES support USB boot), the disks are read, the toshiba applet for recovery is started, and as soon as it gets to the dos-like windows it freezes on "check for medium in drive".
    I have the recovery disks, I have a half working dvd reader in the pc that gives errors when copying the big files and aborts installation. I have an external dvd reader that is recognized at boot, starts the installation, but fails to find "the medium"...
    I hope I have explained my problem more or less.. what can I do (apart from buying a new working dvd reader for the computer) ?
    If there are specific info I need to give on hardware/software, please let me know.
    Thanks,

  • Does Boot Camp work with Fusion Drive

    After having Boot Camp fail this morning while partitioning the drive, and now having to erase and restore my entire hard drive, 500GB worth of crap, I am wondering -- does Boot Camp work with the fusion drive?  My new iMac has one of these things, and I am wondering if that is maybe the reason it did not work.
    Thanks

    While that is true the actual performance available depends on how much resources you have, and how much is made available to Windows. (Win 7 in BC on my iMac gets a 5.9, in a VM it gets a 4.8) all the reduction is in the graphics performance. Disk performance in the VM is faster. I have 16GB or Ram, the VM gets 8 of that when it is running.
    If games are to played a VM is useless.

  • Planning to get New 27" Does Boot camp work with the 1T and 3T Fusions Drives

    I am planning to get a NEW 27" IMAC [if they ever come out] and use Parallels Desktop® 8 or Bootcamp for Gamming.
    Going with:
    27" 3.4GHz quad-core Intel core I7 with 8MB L3 cache
    8GB Ram - Upgrade to 32GB 1600MHz DDR3 from Crucial or OWC
    3TB 7200rpm Fusion Drive
    NVIDIA GeForce GTX 680MX Graphic processor with 2GB of GDDR5 memory
    AppleCare Protection Plan
    Samsung SE-506AB Slim Portable Blu-ray Writer =+$89.
    I work with Photoshop, some Video and Play World of Warcraft.
    Planning to do Gaming on the PC Side with using Bootcamp or Parallels Desktop® 8.
    As you see I was planning to get the 3TB 7200rpm Fusion Drive.
    But I don't know if it would work with Bootcamp.
    Not sure if a separate Volume need to be made for the PC side?
    If a 768 SSD would work?
    Or do I have to go with Regular hard drive?

    Hello,
    Kind of funny, the 3 TB isn;tsupported for BootCamp!?
    Frequently Asked Questions
    Do I need to configure Fusion Drive?
    When ordered with a Fusion Drive, your iMac or Mac mini is pre-configured.
    Can external USB, FireWire, or Thunderbolt hard drives be added to Fusion Drive?
    An external drive cannot be used as part of a Fusion Drive volume. Fusion Drive is designed to work with an internal hard disk drive and internal flash storage.
    Can I add a partition to the hard disk with Fusion Drive?
    Using Disk Utility, you can add one partition to the hard disk on Fusion Drive. Once you add the partition, the "plus" symbol in Disk Utility to add additional partitions will be grayed out. You cannot partition the Flash storage.
    If I create a hard disk partition is it part of Fusion Drive?
    The additional partition is not part of Fusion Drive. The new partition is a separate volume that is physically located on the hard disk drive.
    Can I add a Windows partition?
    You can create one additional partition on the hard disk with Fusion Drive. You can create either a Mac OS X partition or a Windows partition.
    If creating a Windows partition, use Boot Camp Assistant to create it, not Disk Utility. From the Go menu, choose Utilities. Then, double-click Boot Camp Assistant and follow the onscreen instructions. For more information on Boot Camp see the Boot Camp support page.
    Note: Boot Camp Assistant is not supported at this time on 3TB hard drive configurations.
