After I installed Lion, my MacBook Pro can no longer detect my external hard drives or my USB flash drives. What should I do?

And me -- My Mac at work running Snow Leopard reads the drive normally. My home Mac (on Lion) can't even find it....
Yet another Leo let-down.....

Apple Portables: Troubleshooting the slot load optical disc drive

Since installing Maverick my MacBook Air is no longer showing my external Hard drive, which I connect via USB.

I know the external hard drive is working and the USB port works also.
I have seen lots of complicated answers on here but nothing I can understand.
Any help appriciated.

The WD hard drive itself is probably fine, the enclosure has likely failed. WD externals are notorius for cheap enclosures failing. Try a different cable first. You can take the drive out and install it in a better enclosure, like one from OWC.

HT1338 the Macbook Pro would not even detect the external monitor.

My Macbook pro will not connect to an external monitor after moving it. It has been running on this same monitor for 8 months. I switched to a new Desk last night, after hooking it up, the Macbook Pro would not even detect the external monitor. It was only showing the Macs monitor in Display. It did not even have where you could "Detect Display" available. Is there an update that I may have missed. I have tested all the Monitor connections with another laptop they all work.

finally I would like to know if my computer falls under

If nothing displays but you hear normal startup sounds, then it's possible this is a video issue, and you should take it to an Apple store or AASP.

How to backup MacBook Pro without AirPort Time Capsule or External hard drive

How to backup MacBook Pro without AirPort Time Capsule or External hard drive

This is crude but if you need a work around, just plug the USB drive directly into the iMac.. copy the files to it.. then plug it into the TC.
You also do not need to use the TC as an intermediary between your iMac and MBP.. just turn on sharing in the computer.. so you can directly copy files from one to the other.. Macs have public access directory preconfigured for each user account.
As far as mounting the TC..
In finder use Go, Connect to server.. and type.
AFP://TCname or TCipaddress
Where TCname is the actual name of the TC.. I strongly recommend you follow SMB network rules.. ie if your TC has a name like
Fred Blog's Time Capsule 2445566.
It is too long.. it has spaces and it has non-alphanumeric characters.
Shorten it to FredTC
No spaces no characters that are NOT alphanumeric.
TCIPaddress is simply the standard IP.
You can also use CIFS://TCname which according to the article forces the connection back to SMB1 rather than SMB2 which as usual is broken.
But I would definitely use AFP if possible. I cannot understand the decision to move to SMB as standard.

The monitor of my MacBook Pro suddenly became all black, I tried to reset but it did not work, what should I do? Why does this happen?

I advise to reply to the one you want to reply to.
You have had good information here. I will not repeat that here.
I would like to add:
you have incompatible software: start in SafeMode, read Woodmeister and see if it is free of issues.
Akamai is crap software needed or not, Huawei the same.
It is very possible that the keygenerator you used for generating a key for some softwares has infected your mac.
The non-regular software with the false key(s) are not compatible probably or generate malware. Luckily you can not update them automatically because the keygenerator blocked the software for contacting the developer... I propose to consider getting rid of those softwares by really good uninstalling.
You have a beautiful mac, don't degenerate it with crapped software. There are alternatives for expensive software, for example Adobe Photoshop has a free alternative (with a less beautiful interface) in GIMP. And so on.

iTunes > preferences > advanced.
point iTunes media folder location to the external
on the same tab, ensure the copy files ... when adding option is checkmarked
okay out of preferences
highlight the content to be moved (i.e. the movies) in iTunes and right-click
select consolidate files from the pop-up menu
wait for the process to finish
when done, you may delete the original files from your boot drive. you may also want to point iTunes media folder location back to your local iTunes folder.

no. airport express does not support the airdisk feature. you'd need an airport extreme (or time capsule) for that.

TimeMachine Confused: Can no longer access my external hard disk

Suddenly this morning after 3 days of use time machine can no longer access my external USB 2.0 disk. It states failed to access disk. Although I can access the disk fine via the finder. In the preferences I try to reselect the disk but its not listed. I tried rebooting and it still can't see my usb disk, although again the finder can access it fine.
HELP!

The same thing had happened to me with my new USB2 drive. I found [this fix|http://gizmodo.com/gadgets/apple/leopard-disk-utility-format-issue-screws-w ith-time-machine-but-theres-an-easy-fix-316573.php] on another thread and it worked for me (so far).
Before the fix, Disk Utility showed my USB drive partition as Mac OS Extended (Journaled), but it showed the volume still as FAT32.
I certainly don't know if this was the problem, but my drive would only randomly work with TM or the Finder. After the fix, at least for the last 12 hours, the drive has worked correctly with both.

The Imovie instaled in my MacBook Pro can't imported iMovie for iOS

Hello,
I've been trying to open an IMovie in my MacBook Pro that I transferred from my IPad through ITunes. However I receive the following message from the IMovie: This version of iMovie cannot import Trailers created in iMovie for iOS. I have IMovie 11 installed and it has all current updates.
Any help will be appreciated,
Thanks,

Can no longer access my external hard drive

My husband I and switched to a Mac after using Windows machines for years. We have a Free Agent external hard drive to store ALL of our music files and, most importantly, our photos. When we first got the Mac, we plugged in the FreeAgent and it worked fine (obviously, I couldn't write to it, only read the files, but that was basically fine). In the last few days, I realized I can't access the drive at all, no icon, nothing under Computer, no ability in iTunes or iPhoto, nothing. I unplugged its and powered both the Mac and the FreeAgent down, and then reconnected everything and that did not help. Any thoughts or suggestions? It would break my heart to lose my photos. I have a lot of them backed up on removable media, but I take a lot of pictures and stand to lose hundreds.
This is a possible duplicate post, so please bear with me. Our Mac was purchased at the end of May 2012, but we have not upgraded to Mountain Lion. As the Genius in the store put it the night we bought the computer: it's better we learn our way around the system as it is now without all the extra bells and whistles.

Thank you so much for your response. I tried your steps this evening...both of them, and still don't find the FreeAgent drive. I don't have my Windows laptop here at home, but will bring it over so that I can connect the external drive and make sure that there's still DATA on the darn thing. If all the files are still there and can be accessed through a Windows machine, then I guess all is not lost. I'll have to look into purchasing a new external drive to work with the Mac now.
I apologize for the lack of info on my system. I am brand new to Mac - as stated, we only purchased our first-ever Mac back at the end of May and then I almost immediately started a new job, so I haven't really had time to get to know the ins-and-outs of the system. For instance, I don't know where to look to get OS info..all I can tell you is that the machine is 4 months old and I haven't installed Mountain Lion yet. I don't have a boatload of apps installed either - pretty much what came with the computer with the additon of MS Office for the Mac, which I needed for work and school.
The external hard drive was initially used with Windows machines, so when it WAS working with the Mac, I wasn't able to write to it, but the files were all there. Because there are days at a time now where I don't come near the computer, I can't say when the FreeAgent stopped working with the Mac.
Thanks for your help, and if you have any other suggestions, I'd be very appreciative.
