MacBook Pro :: Doesn't Recognize External Harddrive

Mar 6, 2012

my mac book pro is not recognizing my WD 500 GB external hardrive. I checked and double checked to make sure the external was mac compatible before I bought : and it was. It also is not recongizing an WD external hardrive I borrowed from a co-worker.  Here is what I have done and checked so far. 

- I checked to see if the externals worked on other Mac Pros( just to double check mac compatibility)-  they showed up on on 4 different Mac books.

- I checked to see if  there was something wrong my usb ports. So I incerted my 4 GB flash drive in the USB port, and then my co-workers 4GB  Flashdrive-  My computer recognized both the devices.

-  My computer was very full ( that is why I bought a bigger hardrive to back up my files) so  I thought  maybe there just wasnted even enough free space for my computer to recongize the devices. So I freed up 70GB of hardrive space on my mac book. - still nothing.

- I also checked to make sure  I had the suggested software updates to run the drive, before I bought it.

MacBook Pro :: Doesn't Recognize External HD And Bluetooth Unavailable?

Oct 19, 2009

so just like the title says I'm having some trouble as I did a recent upgrade to snow leopard and I have been beach balling a lot. I read that I should do a fresh install and heres where I ran into problems. My external HD is not appearing in finder. It used to work just fine before and it works fine on all of my roommates macs. I tried rebooting to see if it would fix the problem and all that happened was it made my bluetooth module say it was unavailable. Anyone have any ideas on what to do?

MacBook :: Laptop Doesn't Recognize External Keyboard And Mouse

Mar 21, 2012

When my laptop stopped recognizing my external keyboard and mouse I searched the discussions and found an answer that has worked, but only temporarily. It was to do a PRAM reset 3 times and when I do this the keyboard and mouse work fine. But when I disconnect the mouse and keyboard and then later reconnect it will not recognize them. I have repeated the PRAM reset 3 times each time this has happened (4 times) and they work fine but then there is always a problem when I disconnect and reconnect.

IMac (Intel) :: Migration Assistant Doesn't Recognize Time Machine On External HDD

Sep 1, 2014

Using Migration Assistant, I'm trying to transfer back-up files (whole system) from my Western Digital, External HDD to a new-to-me iMac which I've just purchased used. The External HDD has all my files (hopefully!) from my recently stolen iMac. As you can imagine, the circumstances are a bit unexpected and unsettling.

I've followed Apple's instructions for using MA with an external drive, but get hung up like others before me when it comes time for my new (used) computer to locate the disc from which to transfer the files. I've read the replies to others who have posted with similar difficulties using Snow Leopard, but resolving the issue seems to be just out of reach.  

Original computer is now unavailable (stolen); it last ran on Snow Leopard, 10.6.3 to 6.8.New computer is used, and also runs on 10.6.8.Both computers are iMac 2009, tho slightly different versions, if that has any bearing on things.I created a temporary account on my new-to-me computer to make the data transfer, so that there wouldn't be an accounts conflict, as others have suggested.Western Digital External HDD, "My Book, Studio Edition," 1TB. I'm using the FireWire 800 port on the iMac. If I need to erase the hard drive on my "new" computer, I'll need a little instruction and hand-holding on that one.

Hardware :: Won't Recognize My Simpletech Harddrive

Jun 24, 2008

So today, i got a warning message from time machine saying it's past 10 days blah blah, so i plugged it my external harddrive to back up my stuff. At first, it recognized it and i thought it was backing up since i saw that logo turning counterclockwise.

Then when it stopped turning, i just close the lid of my MBP (btw running leopard) to eat dinner. When i came back and opened the lid, it says "improper removal of blah blah" but it was still plugged in. so i unplugged it.

Later, i saw that the exclamation mark is still there inside the time machine logo, so i plugged the hd back in but now nothing shows up.

i have a simpletech hard drive running MBP leopard, the latest.

MacBook :: External Harddrive Shows Up With A Red Minus Sign?

Sep 6, 2009

Problem: I have a half-terabyte external harddrive by western digital. It's been working for about a year now, no problems ever. it's basically halfway filled with movies and music and stuff; however, recently, it's not being recognized by my macbook. It uses a mini USB to USB cable. I switched the cables and it still didn't come up.

When I plug it into the AC it lights up and looks like its searching to 'talk' with my macbook. It has always done this, then the light would become solid and it would show up on my desktop. I tried it on different computers as well and it still doesn't actually show up. All the computers I've tried notify me that a drive has been connected, but not recognized. I really really need it to be recognized or else I lost A LOT of information.

I went to upload a file to Mediafire, and when it redirected me to Finder, my hard drive was the default folder to pick the files from. However, it had a red minus sign on it and I have no clue what that means.

OS X Technologies :: MYSql Doesn't Start After Restoring Harddrive From TM Backup?

Jun 11, 2012

Macbook Pro running Lion V 10.7.4 .After a hard drive failure this weekend, I restored frm my most recent backup.Unfortunately this did not include svn, host file changes and some other fairly easy to correct things.The one that has been giving me trouble for the last 8 hours is mysql. I have gone through and removed mysql (multiple times) and did fresh installs. Each time I was getting the error: 

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (38) 

Even after changing my /etc/my.cnf file to point to var/lib/mysql/mysql.sock I would get these errors.  

Are there multiple locations where mysql points to /tmp/mysql.sock?  

I am at a loss of what to do. I have uninstalled reeinstalled. Tried many different solutions all to reeive the same error.

MacBook Pro :: It Doesn't Recognize Password

Apr 10, 2012

my GF and a glass of Wine. Cat hits wine and wine hits MBP. The Mac shut off instantly, we acted pretty quick and mopped up and turned upside down. I then took back off and over the course of the next 5 days I have stripped it down completely including the Key board and cleaned as best as I could. I've put it all back together and it starts up, a reassuring tone rings out, then apple sign appears with a loading bar beneath, this takes a while then it reaches the Lion log in page.It still recognizes me, or rather my name as the user but refuses my password which I know is correct.The keyboard isn't backlit but keys are typing something (can't see characters, just dots). Screen brightness works.No back light on keys although this may be normal at this point, not sure.

MacBook Pro :: Intel HD 4000 Doesn't Recognize RAM In Mid 2012

Jul 1, 2012

My shiny new Macbook Pro has already had a logicboard (Mac-ish for motherboard) replaced due to this. Games (tested Battlefield Bad Company 2 and GTA IV) crash within a few minutes with the screen freezing and showing random colors as the sound starts stuttering and the only solution is to do a hard restart - see image below. GTA IV tells me that it only recognizes 60 MB VRAM so I guess that the problem is with the graphic card not being able to use the computers onbard RAM (8 GB Corsair Vengeance). The RAM doesn't fail any tests and the computer works like a charm in OSX for days on end, even with heavy Lightroom/Photoshop use. Drivers are up to date.

MacBook Pro :: Doesn't Recognize Portable Hard Drive Anymore

Jun 21, 2014

To provide some background on my issue, my portable hard drive format was NTFS, and I wished for it to be FAT-32.  I was trying to transfer some files over from my Windows computer to my Mac, however it wouldn't work due to the formatting.  To change the formatting, I used some third-party software and started the conversion (without formatting the drive so that I could keep all my files) however mid way through the process, my stupid laptop entered sleep mode and stopped everything.   

When I tried to re-plug the hard drive in my Mac, it didn't show up in the finder, but the Disk Utility did find it.  The model I have is the iStorage DiskGenie portable hard drive.

May 30, 2009

So i bought this new 500GB external HD but whenever i tried to put my files in it from my mac it wont allow me and say, "This item could not be moved because [harddrive] cannot be modified." however if i connect it to my windows it works fine.

P.S just one stupid question, why would a 500GB HD has less capacity such as 470 or so; and sometimes 8GB USB will only have 7.5 G etc.
