MBP doesn't recognize my portable hard drive anymore

Hello!
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.

I would really appreciate any help.
Thanks

What if there was no backup of the data? (It had about 130GB on there/750GB)
That was a bad decision, you may have lost the data.
If you want to try to recover it you will need some data recovery software, and you need to stop using the drive at once. Don't use it until you have recovery software.
What 3rd party software did you use to mess your drive up, maybe a warning to others?

My MBP won't recognize my external hard drive

I have an external hard drive that used to work just fine on my MBP, but now it won't recognize it. When I plug it in (USB), the green light turns on the hard drive, but nothing happens on my MBP. Maybe it is recognizing but not letting me know? I did check disk utility but it's not there either.

Drives "unmounted" sometimes suffer volume structure damage or similar. Sometimes it's correctable without re-formatting the drive, but not always. Depending on whether or not it contains stuff you want to keep, I'd think you have two choices:
1. If you don't mind losing what's on it: Reformat the drive (which will erase the contents), using Disk Utility, or just accept the "initialize" option you are offered.
2. If you want to try to retain the drive's contents, you'll have to try to repair the disk by whatever means available to you. Disk Utility (which is part of the OS, so you own it already), DiskWarrior, and TechTool Pro may be able to detect the drive. If so, try to Repair Disk, Repair Volume Structure, etc. If the disk can't be recognized, you'll probably have to resort to the previous method.
But if this doesn't work, wait for more advice before doing anything rash, as others may think of things I didn't.

Imac doesn't recognize my external hard drive--all of a sudden

i've been using a LaCie external hard drive as my timemachine back up for several years without incident. a few days ago i unplugged the lacie and when i plugged it back in, imac could no longer recognize it. when i go to time machine and try to"select disc" it tells me there is none to select. when i go to system prefs disc utility i can see the lacie icon in the left column, but when i click on it i just get the spinning beachball forever, and have to force quit. any thoughts?

Your HD might be corrupted, try going to spotlight, look up "Disk Utility" select your external and verify disk, there might be some errors on the disk, if so, then click repair disk, try that and get back to us.

MacBook Air doesn't recognize its own hard drive.

Hey, so I have a MacBook Air that I purchased in 2012 and last night, I was going to download the new update for my iPhone, but before I did, iTunes mentioned something about transferring new purchases. The only thing close enough to consider as such were two new apps I downloaded for free. However, after I synced my iPhone and was about to start the update, it froze. So I restarted it and when I did a blank screen with a flashing question mark showed up. It did that foray hour or two and then I got to the Mac OS X Utilities screen with the four options to restore my computer. I couldn't use any of these though because my computer didn't recognize its hard drive. Planning to take it in for help but would love to hear any suggestions. Thanks!

It sounds like your SSD (Solid State Drive) has failed, mine did the same thing two weeks ago. There has been a problem with the 2012 MBA SSDs and many people have the same issue. If you take it to Apple, they should be able to sort it out.

Time Machine doesn't recognize my external hard drive

My external hard drive is no longer recognized by my iMac. I have had this problem before and had to repartition the drive. There is not a drive that is available when I go into Time Machine preferences. Any ideas?

If you completely repartitioned the external hard drive, you may need to Erase & Reformat each Partition on the drive now in order for them to be recognized. You can do that in Disk Utility.

MacBook Pro Laptop doesn't recognize new internal hard drive

I have a mid-2009 MacBook Pro laptop. Recently I started getting the flashing question mark in the file folder issue. It could not locate my hard drive. I tried all the basic troubleshooting steps which did not work. So, I then replaced the hard drive and the SATA cable. I restarted it with my Snow Leopard installation disk, but the hard drive still will not show up in Disk Utilities or when I try to restart and am given the option to choose a different drive. It also does not show up when I try to do an installation. Please help!

I'd suggest double checking the new SATA cable connections just to make sure they're on correctly. If you have an external housing you can put the drive in there and see if Disk Utility sees it. That will at least verify the drive is good.

My new iMac doesn't recognize my external hard drive

I've been using a Seagate external hard drive to back-up everything from my old laptop. I just got a new iMac and plugged it in (via USB) and it's not recognizing it. I can't find it in the Mac system. I'm not super computer savy but on other iMacs I've used when I've plugged in something external (iPhone, camera card, thumb drive) it pops up right away.
Any help you can give me would be much appreciated. THANK YOU!

So what is the APPLE HDD?
Here is a screenshot of my devices on my iMac:
The top entry is the internal hard drive and "iMac ML" is the one and only partition on it which is by default normally "Macintosh HD" - I renamed it (except the hidden recovery).
Can you post a screenshot of yours?

Mac doesn't recognize Seagate external hard drive

I've been using a Seagate Free Agent Go Flex external hard drive to back up as Time Machine. Today, I plugged in the hard drive and my mac didn't see it in Finder. I could see it in disk utility. I ran verify and that failed and told me to repair the volume. I ran repair and it failed and gave me the following message, "Disk Utility Stopped repairing Free Agent Go Flex Mac OS Extended Format. Disk Utility can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files." Since I can't see the disk in Finder, how can get the files off the external drive? Has anyone else had experience with this?
Thanks!

Well, it's either erase it/them, or trry stronger Disk Repair Utilities...
You must repair the HD, if Disk Utility or fsck should fail to repair it, your best bet is DiskWarrior from Alsoft, you'll need the CD to boot from if you don't have another boot drive...

Your best bet is DiskWarrior, you need the CD/DVD though.

Why won't my computer recognize my external hard drive anymore?

I have an external hard drive I was using all morning. This afternoon, the hard drive isn't showing up on my desktop. It does show up in my system profiler under usb. When I go to disk utility to repair it, it isn't there. Please help!!!

No. Any other external drive I plug in works. This particular one, I was using the morning before it disappeared. I know the drive works with this computer I have been using it with this computer for months with no problems. It shows up in the system profiler (image 1), but not in disk utility (image 2) or on my desktop (image 3)

IMAC doesn't recognize lacie external hard drive

Friends,
I have an imac 2013 3TB fusion drive running Mavericks. I have a lacie external quadra drive USB 3.0. When I turn on the drive, the computer does not recognize it. However, if I restart the computer, it then will recognize the drive. Why is this? Is there a preference or something I can change?
Thanks!
Steve

My Macbook Pro doesn't recognize my external hard drive

I had my external HD attached to my MBpro when I attempted to empty trash. The trash window showed it emptying thousand upon thousands of files (way more than was in the bin) and had a negative sign in front of the number of items being deleted. I canceled the emptying, but now the computer won't recognize the HD. It appears in Disk utility but not in desktop or sidebar. What happened and how do I fix it?

In Disk Utility, try using the Mount button in the top menu.
Disconnect the external drive, turn it off, wait about 1 minute, reconnect, and turn it back on. While waiting, restart the computer.

New shuffle & portable hard drive

I'm currently managing a family of 3 IPods on 1 computer and have our music files stored on a portable hard drive. We are trying to add a 4th IPod, which is a shuffle and for some reason when the new IPod is synced, my computer will not recognize the portable hard drive so we cannot fill the new IPod with music. If the new IPod is not connected, then the computer finds the portable drive with no issue (the other IPods work fine). I know to go to advanced settings and change the musice storage location on the new IPod to the portable hard drive but I can't select that drive when the new IPod is connected so they never get synced together. Any suggestions?

Get an externally powered USB hub... shuffle is power hungry. Apparently your USB controller doesn't provide enough power.

MacBook pro does not recognize my WD external hard drive anymore

I use TIme Machine on my WD external hard drive. Everything was working great up until about a month ago. My MacBook Pro does not recognize my external hard drive anymore...I have done nothing differently than usual. I did search in previous discussions and tried rebooting both the hard drive and the computer.
The USB port is fine as it does recognize another external hard drive and also pen drives....Please help! I haven't backed up in a month and need to figure out how to get this to work soon. Should I call WD?

Does the WD drive show in Disk Utility?
Many times, a USB port simply cannot provide the power a hard drive needs. It is not uncommon for any electric motor to draw more power as it ages. A drive that worked before can stop working when it gets older because age has made it tak more power than any USB port can supply. There are a couple of cheap things to try:
1) A "Y" USB cable---two plugs go to the computer and one to hte drive, giving a power boost.
1 Meter USB 2.0 A to 5 Pin Mini B Cable - Auxiliary USB "Y" Power Design for external hard drives.
2) a POWERED USB hub. That takes the power delivery burden off the USB port so it can deal with data.
WD bare drives are fine but their enclosures are not very Mac-friendly. One thing that has reported helping is to get rid of the proprietary formating that WD puts on their drives. If you don't have to share the drive with a Windows computer, use Disk Utility to erase and reformat the drive to Macintosh Extended Journaled.

Windows 7 did not recognize my Seagate Portable Hard Drive

Hello,
On my Toshiba laptop, Windows Vista recognizes easily my Seagate Portable Hard Drive STBU1000102. But my HP Laptop (with Windows 7) cannot recognize my Seagate External Hard Drive. Normaly the model STBU1000102 should work on Mac and PC. I went on Computer
Management of windows. On vista, the disk appears correctly but on windows 7 (Universal Serial Bus controllers), the icon of USB appears with a yellow mark. When I tried to install it on windows 7, the driver is found but I received the message "Access
is denied".
Could you help me ?

Hello,
I thank you for your help. But up to now the problem is not solved.
I forgot to add that I have in Device Manager the following message :
The drivers for this device are not installed. (Code 28)
I made a search on the Internet about the message "Code 28". I tried the tests proposed. No solution.
But I learnt that one of the cause of "code 28" is a wrong driver.
Then I doubt now about my understanding of this message of Seagate about the device :
This software allows you to mount the NTFS partition on a GoFlex drive as read and write (NTFS would normally be read only in MacOS), so the drive can be used to drag and drop files
between a computer running MacOS and one running Windows. This image file includes an uninstall file that was not included with some early drives.
And even Amazon writes :
Install the pre-loaded NTFS driver for Mac and use the drive interchangeably between PC and Mac computers without reformatting
Does that mean that the driver of this device has to be installed on MAC OS ?

I just purchased a new computer and want to synch my iPod. My music (including iTunes purchases and my personal CD rips) is located on a WD portable hard drive. What do I do to synch my iPod and have it recognize the music on the WD drive ?

I just purchased a new Toshiba laptop with Windows 7 Home Premium (Service Pack 1) OS. I own an iPod Classic that has always been synched with my old laptop. All my music (including iTunes purchases and personal music CD rips) is on a WD portable hard drive. What are the steps to take to synch my existing iPod with my new laptop and get all the music ?

Import the music on the external HD into iTunes. If you don't want iTunes to make a new copy of each track that is stored in your iTunes Media folder on your PC's internal HD, make sure the Copy files to iTunes Media folder when adding to library option is NOT ticked from under the Advanced tab of iTunes Preferences. Just remember that if you go this route, you'll always need to have your external HD plugged in before you start up iTunes.
