My usb drive won't connect to my macbook anymore.

It says:
MAC OS X can't repair the disk:
you can still open or copy files on the disk, but you can't save changes to files on the disk. Back up the disk and reformat it as soon as you can.
How would i go about?

Follow the second part of the advice your Mac gave you. Since you can still copy files, I would advise you to back up the data on it and put the data onto something else, maybe another USB drive or external hard drive. Data storage is quite cheap.
To back up your data, buy a new USB drive that's the same size (or larger) than the one you've got at the moment. Then just plug the old USB drive and the new USB drive in (If you have 2 USB drives) and copy the files over by dragging them.

My usb cord won't connect to my macbook air

Whenever I plug my phone into the USB cord and then into the Macbook Air, it won't connect! The phone vibrates and I can't sync music or photos!
We replaced the Macbook and this is still happening, then we replaced the USB cord with one that we bought at our local Apple store. '
Any advice?

As I said that indicates the cable that you used between the iPod and computer is bad

Help! External drive won't connect after Yosemite 10.10.2 update

I ran the Yosemite 10.10.2 update on my 2013 MacBook Air today, and now I cannot connect to my external Western Digital hard drive. At times, the drive won't connect or show up at all, but at other times, I get a warning that the computer cannot read or repair it. Help! It worked this morning and all of my photos are on there. I know other people have had similar issues, but I haven't found anything resembling a solution. (And yes, I have restarted everything, tried different cords, etc.) Does anyone have any suggestions?
Thank you!

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

My iPhone 5 won't connect to my macbook pro retina over bluetooth?

My iPhone 5 won't connect to my macbook pro retina over bluetooth?

Ah, sure it actually won't. I have the same problem, and I contacted Apple Support. They told me that there is an incompatability between the iphone 5 and MacBook Pro Retina such that Bluetooth pairing is not possible.
The Support Agent actually had the audacity to tell me this was part of the design of the OS on the MacBook Pro, like Windows people saying, "That's not a bug. It's a feature!!"
Personally, I think this is insane. While I was trying to tether the iphone to the MacBook Pro retina for an internet connection, there are other reasons related to file transfers for which one would want to pair the iphone 5 with the MacBook Pro retina.
I am hoping this "feature" is fixed in iOS 7, and/or in some dot release of Mac OS 10.8.
By the way, the personal hotspot feature on my Verizon iphone 5 works great either via a wifi or USB connection. There are occaisions, however, when one would 1) not have a USB cable, and/or 2) have another wifi relationship between the phone and a network that one would not want to have to "forget" in order for it not to connect to that wifi network. The Macbook will not find the iphone as a wifi hotspot if the iphone is connected to wifi in the first place. At least mine won't.

My A'Extreme sometimes won't connect to my MacBook Pro even if I have a green light on the device . I can unplug the ethernet cable and reconnect and it will work fine. all diagnostics say there is nothing wrong. Any ideas ?

This is more about your modem then anything. Sometimes you'll need to unplug and plug back in your modem. Consider it a glitch from the ISP or just the modem in general.
when I need to turn something off then on I try the modem first. This when I'm not doing any ware and tare to the device.

Time Capsule external USB drive won't reconnect remotely over Back To My Mac

I'm running a Mac Mini at work, connected via ethernet to an enterprise network (I have no idea what routers they are using, or how they are set up).
At home, I have a MBP laptop and a Time Capsule (hardwired to cable modem) with an external USB drive attached.
All 3 machines (Mac Mini, MBP, TC via Airport Utility) have Back To My Mac switched on.
I can access the external USB drive on my home TC from my work Mac Mini....until the Mini falls asleep. When I wake it back up, the connection back to the TC fails. However....after restarting the Mini, the connection works again.
My first thought was that the corporate network / firewall / etc was causing the problem - not leaving correct ports open, or someting to that effect. However, I realised that if that were the case, restarting the Mini shouldn't help, but it does.
Does anyone have any idea how sleeping breaks being able to access a TC's external drive remotely over BTMM?
The Mac Mini is a 2.3GHz Core i5 with 8GB RAM and plenty of HD space.
The MBP is a 15" late 2013 retina, 2.6 GHz Core i7, 16 GB RAM, also plenty of HD space.
The TC is a 2 TB 4th generation model.
Thanks!

Sorry that did not work. This works well for me using Lacie drives, but I haven't tried Iomega.
Have you checked Iomega's site to see if any software/firmware updates available?
Also noticed during a quick search that a number of users are reporting mounting problems with Iomega. Not sure if this applies to you or not.

Apple mobile device USB Driver won't install (Code 37) on my 7th Generation iPod Nano

As a result, iTunes won't detect my iPod. But the iPod will charge when I plug it in to my comp, and there is an iPod folder in "My Computer". But after installing iTunes, it no longer says “connected” on the iPod (even though it still charges it). And, in Device manager, there is a yellow exclamation mark that appears in the DVD/CD-ROM drive directly after installing iTunes – there is also a yellow mark next to “Apple mobile device USB Driver” when my iPod is plugged in. For both, it says “Code 37.” I know how to fix the DVD/CD-ROM drive problem (by deleting the filters) but the Apple driver still won't install after that. I've tried troubling shooting this. I uninstalled and reinstalled the drivers, but it hasn't made a difference. And I've uninstalled and reinstalled iTunes multiple times, too, and every time I reinstall iTunes the same thing happens: my iPod no longer says “connected on the screen,” and the DVD/CD-ROM drive gets code 37 again. Also, I tried different USB cables/ports.
Any help of suggestions would be greatly appreciated. And I think I've already read a lot of troubleshooting guides on this site, but haven't had any success so far.

Sorry, I'm confused. What do you mean by “leaving all other USB devices disconnected”? Does that include my mouse, keyboard, etc? And does that mean I uninstall those things in the device manager?

My USB drive won't show up on my MacBook Pro (2012 non retina)

Okay, so I have 2 Macs. 2012 MacBook Pro, and a PPC iMac G4. I want to load music onto my USB drive, but it dosen't show up on my MacBook Pro. My iMac can read the USB without a problem, but the MacBook Pro will not. Iv'e made sure to check off everything in Finder Preferences, and also reveal everything in the Finder Side Bar, but still nothing will happen. I even tried looking for it in Disk Utility, and still nothing. Please Help.

Check that the data cable is securely inserted at both ends.
Try a different cable.
If you're connecting the drive through a hub, connect it directly to a built-in port on the Mac.
If you're connecting it directly, try a different port.
Disconnect all other devices on the bus, or as many as possible.
Test the drive with another Mac. Test another drive with this Mac.
If the drive is bus-powered, but has an AC adapter, connect the adapter.
Boot into Recovery and launch Disk Utility. Is the drive recognized?
If the drive doesn't work under any of the above conditions, and if another drive does work with the same Mac, then the drive has failed. You may be able to salvage the mechanism by removing it from the enclosure and installing it in another one, or in a drive dock.

External USB drive won't mount after 10.9.5 upgrade

Is anyone else reporting the following issue? Immediately after installing OS X update 10.9.5 (13F34) on 09/18, my external USB drive (IOMega 1GB OS X Extended FS) used for Time Machine would no longer mount and isn't recognized.

I have reinstalled the combined 10.9.5 OS upgrade, and verified that the drive works when connected to my other MB Pro (mid-2012 running Yosemite beta 3). There is no third party software that I'm aware of in use for this drive, as it's only for Time Machine backups.
Thanks

Is the drive's icon on the desktop (perhaps behind another icon, which is possible if Finder > View > Cleanup is enabled)?
If not, is the box Finder > Preferences > General > External Disks checked?
Is the drive listed in every Finder window's sidebar?
If not, is the box Finder > Preferences > Sidebar > External Disks checked?
Are Time Machine backups to the drive happening on schedule?
If not, does the drive appear in System Preferences > Time Machine > Select Disk?
Can you open /Volumes/Mac-Mini 2/Backups.backupdb using Finder > Go > Go to Folder...?
Does the drive appear in Disk Utility? Is it (or can it be) mounted there?
Have you tried to plug it in to a USB port on the Mini (not a hub) or into a different USB port on the Mini?
Have you tried this: shut down; unplug the drive; boot the Mac; after you have logged in and the Finder is done populating the desktop and menu bar, plug the drive in?

My iPhone 3GS won't connect to my MacBook Pro via USB.

When I try to connect my iPhone 3GS to my MacBook Pro, there's no sign from either end that they're connected (the device won't show up in iTunes, and it also won't charge).
I've tried the same computer, with the same cable, and a different iPhone, which works fine. I've tried a different computer as well, and the phone won't connect with that one either. When I use the same cable to charge the phone, plugging it in, it charges fine, but it doesn't whenever I plug the USB into a computer. I've tried to go through all settings that may apply, but nothing seems strange, unless I'm overlooking something? The iPhone has fairly recently been fixed (the button didn't work), and I don't think I've tried syncing it since - could it have something to do with that?
I'd be very grateful for any suggestions.

Try restoring via iTunes. I really think it's time for an upgrade. You should really consider an iPhone 4 AT LEAST since they aren't so expensive used. If you check on Craigslist, you can find one for $100. The Retina Display part is so much better than standard resolution on the 3GS and below's screen.

E4200 - Plug in external USB drive & lose network connection

Hi - I have the Linksys E4200 [version 1] and my wireless network is set up and configured. I'm browsing with no issues. Within Linksys setup, FTP & UPnP are enabled. I have a 500GB Toshiba external USB [2.0] hard drive [E05A050DAU2XM]. When I connect it to the E4200 the data light on the modem goes off within 10-20 seconds & I lose network connection. I've tried leaving the drive plugged in and rebooting either/both the cable modem and the router but network connection is not restored until I disconnect the drive & power cycle the router. Not sure what is happening. The modem is a Cisco DPC3010 DOCSIS 3.0. I should also say that this was happening with, I believe, firmware version 1.0.01. I updated to Ver.1.0.06 (build 3) & the issue is still occurring. Thanks so much for anyone who could lend their advice!

It maybe a drive size problem that maybe the problem and not compatible. If a smaller size drive works and the larger does not. then this could be the issue. I don't recommend any drives over 500Gb to 1Tb on the USB. The larger the drives are the more problematic the issues can be and should a drive become full, the longer processing of the information will be come and USB is not the best performance for handling large file xfers and should not be used like dedicated NAS.Some routers are just not compatible with large size USB drives. If you need a large size drive for files and streaming, a dedicated NAS device would be suggested and prefered over USB drives.

USB drive kills wireless connection?

I have a MacBook Pro Late 2008 2.4ghz running OS X 10.6.4. When I plug in my LaCie portable HD via USB, it almost always kills the wireless connection. The LaCie is bus powered, and the connection is via a single USB port.
The LaCie works fine. I never have a problem with it. But it not only has a tendency to disconnect my wireless connection (to a Linksys wrt-54g), but it prevents my MBP from reconnecting. The airport icon will keep searching, and pop up the wireless connection window, but when I try re-connecting to my wireless network with WAP password, it'll fail to connect. When I eject the usb drive, wireless will work fine again.
This doesn't happen every time, but it's fairless consistent. Any ideas on what the problem is and how to fix it?

Obviously, this isn't supposed to happen. Try resetting your computer's PRAM. If that doesn't do the trick, reset your computer's SMC.
If that doesn't do the trick, it could be a software issue. You can search Apple's download website for the correct Combo Updater for your OS (10.5.8 for Leopard, 10.6.4 for Snow Leopard).
If that doesn't do it, I would take the machine to an Apple Store or an Apple-Authorized Service Provider and have it looked at.
Good luck!

My usb drive won't connect to my macbook anymore.
