Drive Became Slow All Of A Sudden

I have an Intel iMac core 2 duo with 1 gig of ram. Attached to a USB port on the back of the computer is a Western Digital Mybook USB 2.0 USB hard drive (250 gig).
The drive has always performed as expected, but about a month ago the write speed to the drive dropped down to a very slow speed. Today it took over an hour to transfer 6 gigs from my main drive to the USB drive. It has not always been this way. Reading from the drive to another drive is still fast.
In the System Profiler it indicates that the drive is USB 2.0 (indicates speed that is 2.0).
I have no idea why writing to the drive has become so slow. My first thought was fragmentation, but in that case reading from the drive would be slow too (probably slower). Also, I took a look and fragmentation is not bad on the drive.
I went to the Western Digital website and did a search but nothing revelant came up.
Anyboy have an idea what might be causing this and how I can fix it?
Thanks,
Tommy

New topic: Drive became dead all of a sudden.
The drive took a crap today and I think there was blood in the stool.
Fortunately I think it is the enclosure (usb controller probably although I am no expert in such matters). The drive spins up ok and sounds normal as it goes through it's pre-mount deal. Then it just sits. The machine under both OS X and windows knows something is connected but can go no further. For all that I know it might just be because a cable is in the port. Actually Disk Utility identifys the drive but can't even run a verification on it. No data is passing. Considering my previous problem I am keeping my fingers crossed that it is the enclosure and not the drive.
That said, does anybody know for certain if these MYBook drives are IDE or SATA? I am going to try other things first of course, but if exhausted I will be buying a new enclosure.
This might be a blessing in disguise as the enery saver "features" of the drive were always a source of frustration for me. I like energy saving devices, but the way this drive went about it was just headache after headache.
Thanks,
Tommy

Thanks Grant for your insight - I might have improved a little bit on my speed at times yet still very slow overall. I am posting my latest EtreCheck report for any insight anyone may be able to offer. I'd also like to ask what the most financially resourceful way to get an inspection of my Macbook would be - I'm fed up .
Thanks again,
Kory

It became ULTRASLOW all of a sudden.I have not used even half of storage or disk space because I use it basically for internet surfing and doing my school work.Any help will be much appreciated.Thanks.

Hello t@singh
Check out the article below for your MacBook Pro running slow and slowing your productivity. Check Activity Monitor to see if your RAM is being used up and also check the hard drive using Disk Utility.

Photoshop incredibly slow all of a sudden! useless :(

i am running CS3 on a mac pro dual quad core. 8GB ram. i have 150 GB free disk space, and a whole second 250 gig hard drive as well.
all of a sudden yesterday, photoshop takes an eternity to load up (a few minutes) and to open even a small 300k image it takes several minutes and i get a beachball.
saving takes forever as well.
my hard drives i checked and ran utilities. no help there. no other application is having troubles.
i then deleted my prefs folder. no help.
reinstalled. no help.
any suggestions? it's so slow i just can't even use it anymore.
insane!

Cocktail is an inexpensive little utility which will do the regular maintenance tasks such as running the Cron Scripts and cleaning out caches etc. at the click of a button. It can do a number of other useful things (including making invisible files visible and letting you choose the format in which to save Screen shots).

Onyx, which is free, is reputed to be similar but I don't know how well it compares with Cocktail because I have never used it.
But you definitely need one of them.

This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem.
If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
Below are instructions to run a UNIX shell script, a type of program. All it does is to gather information about the state of your computer. That information goes nowhere unless you choose to share it on this page. However, you should be cautious about running a program at the instance of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them.
Here's a summary of what you need to do: Copy a line of text from this web page into the window of another application. Wait about a minute. Then paste some other text, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in your browser, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign ($) or a percent sign (%). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important.
If you're not logged in as an administrator, you won't be prompted for your password. The test will still run. It just won't do anything that requires administrator rights.
The test may take up to a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. There is no indication of progress until it's done. Wait for the line "[Process completed]" to appear in the Terminal window. If you don't see that line within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report your results. No harm will be done.
When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
When you post the results, you might see the message, "You have included content in your post that is not permitted."

Time Machine backup painfully slow all of a sudden

For some reason my time machine backups have become painfully slow for some reason. They were fine earlier today, then IIRC I booted windows, then booted back into OSX to run a backup. Despite there being only 1 or two changes (files added to the system) time machine began "preparing backup" by going through all the files on my HDD! Now, it is backing up, but at the rate of about 5 Kb/s!
Something is wrong. I've tried deleting the progress file in the backup folder and "resetting" TM by deselecting the backup drive and selecting it again. Nothing worked. Why would TM be so slow all of a sudden?
Has anyone any ideas?

That is a bit suspicious, but not necessarily wrong. Something caused it to think about 16 GB had been changed (it adds 20% for the "padding" in the message).
How are you running Windoze? Is it on a separate partition? If you're running it via virtualization software, with the vm file on an OSX disk but excluded from TM, that's a possible explanation.
105384 files in only 7.2mb? I doubt it...something seems fishy
Those counts are nearly always very high, and sometimes crazy high. There's some indication it's counting all the metadata, extended attributes, etc., as separate files.
If in doubt, boot up from your Install disc and do a +*Repair Disk+* on your boot volume. Then reboot normally and run another backup. That should trigger a "deep traversal," where TM will compare everything on your system with it's backups, to be sure it's got everything it should.

My mac is running vert slow all of a sudden

I reinstalled 10.7.4 last month with a clean install today my mac mini is very slow all of a sudden. I have made no changes and have not installed any software since the clean install. When I click on anything the mouse cursor becomes the rainbow circle for 1.m16 seconds (sorry tried to give you guys exact info but i only measured it once:)
What i tried up to now:
I tried to boot the mac with cmd r and reinstall. However the moment it connects to the internet the mothing happens i let it run for 2.5 hours and the blue bar did not even give me 1% (my internet on my mac air has no problems.
I checked disk utility and checked disk permissions and repair disk. both no problems
I ran activity monitor and here is the info.

My Moms Desktop is running slow all of a sudden...?

My mother is really upset about her Desktop being slow all of a sudden. But her computer had updated something automatically earlier in the day when I was on. I'm not sure what it was exactly. She also said it was working earlier today as well once I left, and then after that she signed off. Once she logged back in it was way slower than normal. Even when I logged in before she got home tonight it took about 5-10 mintues just to startup from logging onto it. She called the Century Link company to tmake sure it wasn't her internet or anything but the guy just hung up on her while he was asking her a lot of questions that she had already done. And we tried re-starting it, and she said she tried to reboot it but the computer didn't even bring up the restore page because it's really slow. And then after that we finally got to restore the computer it still is running really slow. Is there any other way we can fix this?

If the issue began as the result of an update, then use Windows system restore to put the PC back in the state it was in before the update was performed. Choose a system checkpoint dated just before the update.
You have not stated which operating system is installed. that always helps. Gp into thee Control Panel; and click on Programs and features. In the left side of the window select view installed updates to see what was installed and the specific date. Note the date and then go into System restore. Chose the system checkpoint with the same date as the update and then committ to the system restore point. When the PC is restarted it should return to its formerly percieved speed, if the update was indeed the issue. Afterwards turn off automatic updates and set Windows update to check for updates but let me choose whether to download and install them . Take control of the updates that your PC receives. Don't let the operating system do that for you automatically.

Dresser DXD digital pressure transducer driver became slow with upgrade to 2010

Hello Forum,
I have been using Dresser DXD digital pressure transducer drivers with LabVIEW 2009 without any problems. Recently I upgraded LabVIEW to 2010 and I noticed that data acquisition using the driver became slow and it returns a warning "Dresser DXD default setup is not supported". The warning code is 1073479936. I could not locate this code in the shared folder under the NI installation folder. Do you know what could be the problem with the driver and how I can fix it.
Many thanks in advance,
Zacharia
Solved!

Hello forum,
I could solve the problem with slow data acquisition by using a simpler serial read-write VI.
Thanks as always for the attention

My macbook pro became very slow all of a sudden?

I just bought a used macbook pro early 2012. It was all restored and nice when I got it. It has worked perfectly for about a week and then I don't know why, but all of a sudden it became very slow in every aspect; Booting, opening apps, even surfing on the web became slower and laggy. It also seems like it has a battery problem when it is in standby. Because it uses a lot of power. Actually so much that it might go dead just by standing for a few hours. Is there anything I can do?

In regards to the battery situation, try a SMC reset:
http://support.apple.com/kb/HT3964
Is there a change?
When you got the MBP, was Mavericks the installed OSX? What you may have to do is boot the MBP with the OPTION+COMMAND+R keys. This will connect you to the Apple servers and allow you to erase the HDD and install the original OSX that the MBP came with. This sets up the MBP to your Apple ID and will permit you to install any appropriate updates accordingly. You may then download and install Mavericks from the App Store.
Ciao.

Macbook PRO 2009 running extremely slow all of a sudden

Hello, I have been encountering recent problems regarding my macbook pro 15" from 2009. All of a sudden it became extremely slow and spinning beach ball every time I click something. It used to be very fast it's as if something happened over night. I have already tried re formatting the whole computer and installed a new os x. I verified the hard drive that it's okay and I have already reset the pram. Would love some help please and thank you. Specs for my laptop are: 2.8GHz Intel core 2 duo, 500GB HD, 8GB Ram and it's from 2009. No recent applications were installed.

Hello, I have been encountering recent problems regarding my macbook pro 15" from 2009. All of a sudden it became extremely slow and spinning beach ball every time I click something. It used to be very fast it's as if something happened over night. I have already tried re formatting the whole computer and installed a new os x. I verified the hard drive that it's okay and I have already reset the pram. Would love some help please and thank you.

Airport Extreme Airdisk's REALLY SLOW all of a sudden

I have my media hard drive connected via USB to my Airport Extreme. It serves all the media for my iTunes libraries etc. It's been working flawlessly for months, but now all of a sudden, it's cripplingly slow.
I've been trying to transfer one 800mb video file all night and it keeps saying "21 hours" and only transfers a few kb every minute or two.
I've restarted my Airport Extreme, disconnected and reconnected the USB HD and restarted the ADSL modem the AE connects to the internet through. I've also tried a variety of different files.
No difference.
Any thoughts? I know I could completely reset my AE, but if a restart won't fix it, then I doubt a reset will.

chirhodesign, any update on the situation?
i'm helping my friend overseas with this exact same problem. she just bought a new hdd and as a shared network drive via airport extreme it's EXTREMELY SLOW, maybe around 100kbps transfer rate. we're pulling our hair out trying to troubleshoot this.
does anybody have a possible solution?

IMac running extremely slow all of a sudden

I have a 1st generation Intel iMac (24", late 2006), which ran fine for three years but all of a sudden slowed to a crawl about a month ago. I upgraded to 3GB of RAM, but didn't see any improvement; I've run the disk utility app on the system install disk and didn't get any problems; I don't see anything in the Activity Monitor that's hogging CPU usage (although iTunes uses about 7% while playing music and 20% while playing video - considerably higher when it loads a new track into RAM); and I have 70GB free on a 300GB hard disk. I realize that this is just scratching the surface, so what else should I be looking at? For what it's worth, yes I have an HP printer, but the drivers don't seem to take up that much CPU time; and I'm still on 10.4.11, so maybe it's just time to upgrade to Snow Leopard; but either way I've been on this system (and with this printer) for a long time, and I don't understand why this would happen all of a sudden...
Thanks!

HI,
70GB free disk space could be at least part of the problem for the disk slowing down.
Try Freeing space on your Mac OS X startup disk
Check the startup disk for errors that may need repairing.
Insert your install disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
*(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)*
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your start up disk and click Restart
While you have the Disk Utility window open, look at the bottom of the window. Where you see Capacity and Available. *Make sure there is always 10% to 15% free disk space*
If you cannot boot from your install disc, try booting in Safe Mode
How to Force Background Maintenance
One way to free up disk space...
Open Console. Select system.log then from the Menu Bar click Reveal in Finder then move that log file to the Trash. These logs can take up as much as a GB.

CS4 Really slow all of a sudden!

I am really struggling to work at any reasonable speed with InDesign CS4. It has been fine ever since I got it, but all of a sudden it is crawling along and it is driving me mad. I have tried using fast display, but not good.
I am running a Mac with OSX 10.5.6, Dual 2.66 Intel, and 11 gig of RAM.
Any ideas as to why InDesign is running slow? Everything else seems to be running fine.
Thanks
Mat

Thanks for the suggestions, they sort of have an affect, but, it all starts going pear shaped after about an hour or so.
I have switched off the preflight, colours panel and the auto correct for spelling which seem to make it last that bit longer before it starts to drag its heels, but I am finding that I am basically having to quit a couple of times a day, and also having to restart more often than I like.
To be honest, I am finding it to be a little unstable, is anybody else? The same with photoshop too...
