Trim (SSD) in 10.6.7 - ? and what happens to the SSD if not?

Am I up to date in assuming that there is no way to know when 10.6.7 will be released or whether it'll allow for using the trim function on SSDs (for all, not bizarrely just for new MacBooks)? And, second question, if 10.7 will indeed provide this function for all who's hardware permits it (like all MacPro, I guess)—what will happen to an SSD when in use for, say, 4 months without trimming? Will it degrade irreversibly, or will the use of that trim function then set it to the state it would have been in when trimming for 4 months constantly?
thanks a lot

There are a number of users, and threads, about using SSDs.
TRIM is an OS level feature.
OWC switched to Sand Force and the SF controllers have their own background garbage collection. I haven't seen much about the newest SF-2000s yet.
Allow for over provisioning (when I formatted a couple SSDs, Disk Utility seem to 'map' 5GB or 10%, not sure which, so maybe it sets aside some). I just would get a drive that has extra space.
You'll find Wikipedia has excellent articles on SSD, TRIM, write amplification and more. And Diskeeper blog has an article on the inner workings of SSD.

No it won't be irreversible if there is some. Just keep a backup clone though. And keep SSD to just OS and apps, or if using for scratch, but use a standard mechanical drive for all your data and other purposes.

There is a whole section devoted to SSD (70% down the page)

The rest deals in speculation. Old axiom, we'll know when it gets there, not until.

  • My mac disk is full and i cant transfer files from Mac to USB. saying the format is not good, how can i change the format and what happened to the files i have on USB?

    my mac disk is full and i cant transfer files from Mac to USB. saying the format is not good, how can i change the format and what happened to the files i have on USB?

    Once something similar happened to me. The external drives I had set up for FCP to use for some reason were not mounted, and FCP put all its render files on the main drive and I couldn't find them anywhere.
    Go to applications, and control-click (and hold down) on your FCP icon; you should get a pop up menu that says "show package contents". Select that, select the "contents" folder, then the "mac OS" folder. See if your quicktime file is in there, or if you've got render files in the "render" folder or audio render files in the "audio render" folder that don't belong there.
    That's where FCP sticks stuff when your documents FCP project folders are not available or when external drives you've selected aren't available.

  • Running latest version on OS X and mail.  What happened to the icon labeled "not junk?"  Is there any way to brink it back?

    Running latest version on OS X and mail.  What happened to the icon labeled "not junk?"  Is there any way to bring it back?  Thanks in advance!

    Make sure your Junk Mail settings are properly set up, right now neither of those messages are marked as Junk Mail.  When Mail identifies an item as Junk Mail or you manually do, it will add the text "Mail thinks this message is Junk Mail" or "You marked this message as Junk Mail" to the message.  Right now this just looks like regular SPAM that you might get that hasn't been properly identified as Junk Mail or when Junk Mail Filtering is no enabled.  Remember Mail needs to learn what is and is not Junk Mail over time, so if you have recently reset your mail settings through a reinstall or the like, it may still be learning.
    1.  Do you have a Junk folder (system created) as one of your mailboxes?  If there is none, it means that Junk Mail filtering is not enabled or has been enabled but the system has yet to identify any mail as Junk.
    2.  If you do have a Junk folder, try dragging a piece of mail into the folder to see if the banner I am referring to appears.  It should.  You should be able to unmark the mail and drag it it back in your inbox.
    3.  If you manually mark the mail as Junk, does it move into the Junk folder and have the banner I am referring to?  It should.
    4.  If any of the above is not happening, first check your mail settings using the guides below:
    Mail (Yosemite): Reduce junk mail in your inbox
    Mail (Yosemite): If junk mail filters aren’t working correctly
    If all seems correct and it's still not working right, try rebuilding your mailbox:
    Mail (Yosemite): Rebuild mailboxes
    If none of these help you, please post back and we'll try something else.  Oh, and clear out your Previous Recipients window of any unwanted email addresses.  Anything listed in there is usually ignored by the Junk Mail filters.

    I have the same problem on the latest iTunes software and Windows 7. My window is maximzed and I do not see any tab for photos. Seems related to a recent update (IOS7?) as this was there - at least before the very big change to the interface.

  • How do I enable some scripts to run in some programs/websites and what happened to the status bar of my Mozilla Firefox 4?

    Well, first of all, I was tying to create a web-based computer game in Notepad in H.T.M.L., C++, and JavaScript codes. But when I tried to open the completed product, Firefox only came up with a blank page. What do I do with this? And also, I unwittingly removed the "Status Bar" on the bottom side of my browser(the one that always says "Transferring data from/to..."), and when I tried to bring it back up, I couldn't because I don't know how, since I'm new to Mozilla Firefox 4. If you could help me with these problems, Then I would greatly appreciate it.

    You can install the Status-4-Evar extension to regain some functionality from previous Firefox versions that was lost with the removal of the Status bar.
    Open the Customize window via "View > Toolbars > Customize" or via "Firefox > Options > Toolbar Layout" after you have installed the Status-4-Evar extension and drag the items (Status Text, Progress Meter, Download Status) upon the Add-ons Bar (View > Toolbars > [X] Add-on Bar)<br />
    Also check the Options of Status-4-Evar in Firefox (or Tools) > Add-ons

  • Can't get a decent background to work, and what happened to the 9+ hours visibility on cal?

    So, I use my ipad strictly for school.  The new iOS7 has made it extremely difficult to select my own background and get it into view.  I want to take a picture of my weekly schedule and make it my background, but the iOS7 is insisting on scaling my image.  iOS7 has decided that I need to be slightly zoomed in to use my picture.  Why can't I use the ipad screenshot of my schedule as my background? 
    Plus, isn't work from 8 to 5? Or at least 9 hours counting an hour lunch?  If so, and assuming that people use their calendars to be productive, why is iCal now showing only 8.5 hours and forces you to scroll down to see the afternoon?  Apple, you're claiming you rethought this wonderchild, but instead you've lost practicality! Please stop trying to look like an android tablet and be smarter than your competitors!

    The problem lies with the structure of the data table in 'index2.html' and the way that Spry utilises that data.
    The following shows the first three rows of the table
    <tr>
      <th>Case name</th>
      <th>State</th>
      <th>Region</th>
      <th>Incident type</th>
      <th>Settlement date</th>
      <th></th>
    </tr>
    <tr>
      <td>Allen Owen</td>
      <td>Florida</td>
      <td>Southeast</td>
      <td>Oil Spill</td>
      <td>11/1/2014</td>
      <td><div class="arrow"></div></td>
    </tr>
    <tr>
      <td colspan="6" align="left" valign="top"><img src="ship-2.png" alt="Ship photo" />
        <h4>Additional information</h4>
        <ul>
          <li><a href="#">Case documents</a></li>
          <li><a href="#">More information link 1</a></li>
          <li><a href="#">More information link 2</a></li>
        </ul></td>
    </tr>
    Spry will regard the first row as a header row, thus no problem.
    The second and third rows will be used as data rows, but their structure is not the same. Hence this will confuse Spry and the data will be incorrectly reflected.
    The following are the rows in the Spry Region table
    <tr>
      <th spry:sort="Case_name">Case_name</th>
      <th spry:sort="State">State</th>
      <th spry:sort="Region">Region</th>
      <th spry:sort="Incident_type">Incident_type</th>
      <th spry:sort="Settlement_date">Settlement_date</th>
      <th></th>
    </tr>
    <tr spry:repeat="ds1">
      <td>{Case_name}</td>
      <td></td>
      <td></td>
      <td>{Incident_type}</td>
      <td></td>
      <td><div class="arrow"></div></td>
    </tr>
    Here we have got the header row, thus no problem, but the repeated is going to be a problem. This will repeat the data collected from the data table in 'index2.html', data that we know that Spry has had a problem with.
    In other words, the two widgets will not co-operate with each other. A table structure is too restrictive.
    You may like to have a look at using Spry's Sliding Panel or using an Accordion instead of using a table.

  • Backing up External drives to Time Machine - what happens if the drives are not connected at the same time?

    I have 2 x 1 TB drive that I use interchangeably. 1 holds Video and the other Photos. I only have 1 connected when I'm working (using Premiere or Lightroom). I have a 2 TB NAS for making redundant copy of the other 2 drives.So far I've been doing the copying manually.
    I'm considering of using Time Machine to make proper backup sets (though I'm always only interested in the latest set). I know that I can set Time Machine to backup to Nas over the network and include any external drives connected to the mac at the time.
    The questions now are:
    Will Time Machine fails if it can't find any of the external drives?
    Does Time Machine handle backing up the external drives one at a time - only when it's connected - without thinking the files on the "missing" (or disconnected) volume had been deleted?
    Thanks

  • What happened to the youtube app and why does my ipod keep crashing?

    I updated my ipod touch 4g to iOS 6.0 and what happened to the youtube app? And why does my ipod keep on crashing when ever I go to the app store? Now i can never buy anything!!! or watch youtube videos and I'm always on youtube!!!!!!!!

    As has been very well publicized in the news and all over the internet and forums, youtube is not part of ios 6.  Google it.
    You can get the app from the app store if you like.
    Have you tried the basics from the manual to stop the crashing?

  • What happens to the open item in bsid table when it is cleared

    hi experts,
                   i have a doubt about open and cleared items of accounting documents. as we know open items of customers are stored in bsid and cleared ones in bsad. For suupose, an open item is closed ina particular period then what happened to the entry in bsid and bsad table. an entry regarding is stored in bsad (cleared),and what happens to the entry in bsid, still it will be there or removed from it.

    Hi,
    When ever we clear the document(Complete payment) that document will be moved to BSAD table. Other wise it will remain in BSID.
    If u are making partial payment then all the partial payment documents along with original document will be stored in BSID till u made the complete payment for that invoice.
    Assumption is u have to give all partial payment documents made for particular invoice item while u are making complete payment in F-28 transaction. So that these partail payment documents will also be cleared while making complete payment and moved to BSAD table.
    This trasaction can be used for both partial and complete payments.
    Irrespective of complete or partial payments made all the documents will remain stored in BKPF and BSEG tables.
    BSID and BSAD are index tables to address performance issues with BKPF and BSEG tables.
    So all open and cleared documents will be there in BKPF and BSEG tables.
    All cleared documents will be there in BSAD table.
    Alll open documents will be there in BSID table.
    Hope it is clear.
    Thanks,
    Vinod.

  • What happens when the CC trial ends? What happens when offline?

    I need Lightroom to work offline on my laptop. What happens if I need to sign in to CC when there is no interned connection and what happens when the CC trial ends on both my laptop and desktop?

    Thanks for answering. I have the standalone version of Lightroom 6 on my Windows 7 64 bit desktop. A number of times when have tried to open the program, the Adobe Application Manager has popped up requiring me to sign in even though I had not knowingly signed out. Lightroom will not launch unless I am signed in. Frequently when Lightroom launches, I see a "Server Busy" message telling me to "switch to the other program" without telling me which program to switch to. I have pinned the AAM to my notification area and have unchecked the "Show OS Notifications box" to see if the "Server Busy" message goes away. So far everything seems to be okay
    Again, thanks for answering me

  • What happens when the iphone app won't open on iphone 4?

    what happens when the phone does not open and automatically shuts down the phone?

    Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new).  Try each of these in order until the issue is resolved.

    I had two fans replaced in 2012 on my 2006 MacBook Pro were around £10 each with labor at £20. I don't know that these prices are still viable, but it may give you an estimate.
