What to do? coudn't open my toshiba external hard drive that I can open before

I have a Toshiba external hard drive that I've been using without any problems before I upgraded my OS to Mavericks...Now I couldn't find the drive anymore but it seems that my mac detects it but it just is not opening it anymore...couldn't find it in my finder window....Anyone who knows how to fix this? Thanks.

Have you reset power on both the Mac and hard drive?
From time to time, during sleep/wake cycles, my network attached drive wouldn't show up in my Fiinder. When I would click to Connection, they would come up grayed out. Cycling power on the Mac didn't really help much. But cycling power on the hard drive unit did.

I have a Toshiba external hard drive that i used to back up my Windows 7 HP -- I want to transfer files to my new Mac and it won't accept. Help?

I have a Toshiba external hard drive that I used to back up my Windows 7 HP -- I am not able to get the files off of it (pictures) onto the Mac. I am NOT a very technical person. IS there a simple easy way to explain and do this -- OR a simple way to just say it is not possible?

If you connect the external hard drive to your Mac does it show up in the Finder? If so, do the files you are trying to transfer show up? What happens when you try to move them over?
What kind of Mac are you using and what operating system does it have running on it?
Let us know, we'll keep helping you.
Best of luck.

I'm not sure if my iPhoto library is being backed up by Time Machine. I am backing up to a LaCie external hard drive. I can open photos that are in folders but not those that are in iPhoto.

Do a restore from Time Machine. That will tell you.

What is the best priced External Hard Drive, that I can reboot from, for the MacBook Pro?

I have a MacBook Pro with 10.9.4. I am looking for a 3T External Hard Drive that I can boot from if my system goes south, that I can afford. Any recommendations?
Mike

Don't know the best priced, but the external drives I like best are the OWC, http://www.macsales.com Mercury Elite Pro quad-interface drives. I have four of the 2 TB drives for my MacBook Pro and iMac and they are terrific. OWC is a Mac specialist supplier with the best guarantees and service you will find.

How to set up a Toshiba external hard drive on my Macbook Pro?

Hi there,
I just bought a Toshiba external hard drive that says on the package it is compatible with Macs. I plugged it in, installed the Pogoplug PC for Mac (no idea what this is) and Tuxera NTFS for Mac (it was in the "Mac Driver" folder). Now what? Is my data now automatically going onto the hard drive? Do I need to install anything else? This seems too easy! What am I missing here?
Thanks!

New hard drives out of box should be formatted for your Mac
go to DISK UTILITY and verify what it says your HD is formatted as under the "ERASE" tab
HFS+ above is the "mac format"
Format (erase) it in "mac osx Extended journaled"
AFTER THIS YOU CAN DRAG AND DROP FILES AS YOU LIKE
To show HD on desktop
go into FINDER at top then PREFERENCES then GENERAL tab
then check "hard disks" and "external disks"
There is no such thing as a MAC or PC hard drive,.....they can all be formatted as you wish for either PC or Mac (or both)
FORMAT TYPES
FAT32 (File Allocation Table)
Read/Write FAT32 from both native Windows and native Mac OS X.
Maximum file size: 4GB.
Maximum volume size: 2TB
You can use this format if you share the drive between Mac OS X and Windows computers and have no files larger than 4GB.
NTFS (Windows NT File System)
Read/Write NTFS from native Windows.
Read only NTFS from native Mac OS X
To Read/Write/Format NTFS from Mac OS X, here are some alternatives:
For Mac OS X 10.4 or later (32 or 64-bit), install Paragon (approx $20) (Best Choice for Lion)
Native NTFS support can be enabled in Snow Leopard and Lion, but is not advisable, due to instability.
AirPort Extreme (802.11n) and Time Capsule do not support NTFS
Maximum file size: 16 TB
Maximum volume size: 256TB
You can use this format if you routinely share a drive with multiple Windows systems.
HFS+ ((((MAC FORMAT)))) (Hierarchical File System, a.k.a. Mac OS Extended (Journaled) Don't use case-sensitive)
Read/Write HFS+ from native Mac OS X
Required for Time Machine or Carbon Copy Cloner or SuperDuper! backups of Mac internal hard drive.
To Read HFS+ (but not Write) from Windows, Install HFSExplorer
Maximum file size: 8EiB
Maximum volume size: 8EiB
You can use this format if you only use the drive with Mac OS X, or use it for backups of your Mac OS X internal drive, or if you only share it with one Windows PC (with MacDrive installed on the PC)
EXFAT (FAT64)
Supported in Mac OS X only in 10.6.5 or later.
Not all Windows versions support exFAT.
exFAT (Extended File Allocation Table)
AirPort Extreme (802.11n) and Time Capsule do not support exFAT
Maximum file size: 16 EiB
Maximum volume size: 64 ZiB
You can use this format if it is supported by all computers with which you intend to share the drive. See "disadvantages" for details.

Maverick wont recognize my toshiba external hard drive. Any idea?

Maverick wont recognize my toshiba external hard drive. Two days ago, before attaining Maverick (what a mistaaake), it recognized the external. Now it only recognizes other external hard drives, but not my toshiba. All my music is locked away
Thanks for your time...

Once I press mount it says:
The disk "TOSHIBA EXT" could not be mounted.
Try running First Aid on the disk and then retry mounting.
I have a very valuble music collection on this. I got it around a week ago and it hasn't been acting the same since Maverick. I'm just hoping the problem IS maverick here. But it must be.... Because Maverick won't even recognize my brookstone mini projector. I really appreciate the help, what should I do from here?

HT1338 I bought my macbook pro november 2011 and I still cannot use my toshiba external hard drive. what updates do i need to get?

I don't know my operating system. I bought it in nov of 2011. I am trying to axcess a toshiba external hard drive. what new update do I need to get?

You can find out your current system version by select About This Mac from the Apple menu. To make sure it is updated, select Software Update from the Apple menu. A Mac from Nov. 2011 is probably running "Lion," and the latest version of Lion is Mac OS X 10.7.4.
But that should not affect the connection of an external hard drive. There are no special updates for connecting standard external drives.
Does the external Toshiba drive connect by USB port? Is it the smaller type that gets power from the port (no conection except for the one cable), or is it larger (with its own power supply)?

Why is my Toshiba external hard drive not being recognized by my new Mac?

So: When I moved from Colombia I packed my stuff in an external hard drive, that was at the end of last year, Today I got my new MacBook Pro and I can't transfer my stuff because it doesn't even pop up anywhere. I read some other people's post and no: It doesn't appear in any of the two places people say it should appear (or I am not seeing it) whenever it doesn't automatically appears in desktop.
Funny story: It appears that my Mac's hard drive is a toshiba, the same brand as my 1tb external hard drive.
Suggestions?

I'm having the exact same problem... I have my Toshiba 1TB Hard Drive which I formatted to FAT32 so I was able to watch films on my PS3 off of it and recently got a MacBook Pro 13" i7 8GB RAM 750GB HDD, which is unable to read it (and I'm experiencing the same White Light when used with a PC and PS3 - which is when it works, and Blue Light when it is plugged into my MacBook and unable to open).
I've tried to follow as many instructions as possible that I've found on the internet but nothing seems to work - it won't even appear in Disk Utility, I don't know what to do. All I need to know is whether this a problem that can be fixed or not - otherwise I'll just get a new Hard Drive.

How do I get my MacBook Pro to recognize my Toshiba external hard drive?

How do I get my MacBook Pro to recognize my Toshiba external hard drive? I'm working on transferring my music from our home computer to my new laptop and I already got all my music onto the hard drive but now, when I plug it into my MacBook Pro, it doesn't recognize it. There isn't an icon that pops up and nothing happens at all. The blue light on the hard drive that indicates that it knows it is plugged into something comes up but that's about it. Someone told me I might have to "format" it but I don't know what that means and I don't know how to do it. I just want to get my music from the hard drive to my laptop so please help!

I don't know about your first question... I went to finder, preferences, then general but I didn't see anything for the hard drive.
Huh, in the Finder menu, Preferences, you will see this:
Nope, disk utility cannot see it. I've tried unplugging it and plugging it back in but it still won't recognize it.puter that's a Mac...
If DU cannot see it then the preferences is just an academic exercise.
If this is a USB drive then as mentioned above you may need a powered USB hub since there may not be enough power from the USB to run the drive. What else do you have plugged into the USB ports? If there's some stuff you can unplug it then do it and see if your drive mounts.
What do you mean from a Windows machine? It's a Toshiba hard drive and I put my music on it from my home computer that's a Mac...
Which is all I wanted to know, i.e., whether the drive came from a Winows machine. So it's been formatted and created on a mac. Therefore it should mount on this other mac machine. So it most likely is a power problem.

I have an external hard drive that I have been using for years. All of a sudden my mac will not recognize the external as a "save as" device location. But the external does show up on my desktop and I can open it to drag and drop items. Help.

Hi,
Check Finder>Preferences>Sidebar, is it checked there to show external drives?

IPhoto library on external hard drive will no longer open

I'm hoping that someone will be able to point me to a simple solution to my problem...
I'm running iPhoto 9.6 on a MacBook Pro (Retina, 13 inch, mid-2014). The OS is Yosemite 10.10.1. Because the flash storage is only 250GB I have my main iPhoto library (146GB) on a partition of an external 1TB Lacie Rugged drive. The external hard drive also has partitions for Time Machine Backup and SuperDuper Bootable Clone. I have a separate, much smaller iPhoto library on the MBP which contains recent photos.
Yesterday I failed to reconnect my MacBook Pro to the power source when I put it back on my desk. The result was that the battery went below 5% and the MBP turned itself off and also ejected the external hard drive (some time after I reconnected the power cable there were dialog boxes on my screen informing me that each of the three partitions had been ejected incorrectly). I waited until the MBP was fully charged before I tried to open my 'main' iPhoto library on the external hard drive. I received a message that the library would have to be upgraded to work with the computer (very odd, because it had already been upgraded last October when I upgraded from Mavericks to Yosemite and has been working without any real problem ever since then).
After some hours when the only message on the screen was 'Rebuiding Thumbnail Caches' I pressed Cmd+Option+Esc I saw that iPhoto was 'Paused' - that message subsequently changed to 'Not Responding'. I 'Force Quit' iPhoto but the iPhoto library will not open at all from the external drive.
As a test I quit iPhoto and re-started using the Option key and chose to open the iPhoto library which is on the internal drive and it opened without any problem.
I recall that it used to be possible to fix this sort of thing (perhaps not) by trashing the com.apple.iPhoto.plist file, however, I don't seem to be able to find it :-(
I'm really at a loss as to how I should approach this problem and I would be very grateful for any suggestions that can be offered.
Cheers
Tricia

Further update ....
I downloaded and installed iPhoto Library Manager and then chose Library - Rebuild Library. Unfortunately, when it had finished the result was 0 images in any file or folder. I checked the log (which is incredibly long) but here's the beginning of it which seems to indicate that the problem is that an essential file is missing -

After this each entry has a dialog that basically says the image file is missing from /Volumes/Pictures/iPhoto Library.
As mentioned in an earlier post I do have another iPhoto Library on my 2008 MacBook.
Can someone advise the best way to proceed? I'm thinking that I should erase the partition of my external hard drive that is called Pictures and then connect the external hard drive to my 2008 MacBook and simply drag and drop the iPhoto Library to the Pictures partition. IIRC, that's the way I moved the iPhoto Library last October when I bought my new MacBook Pro which didn't have enough storage for me to be able to store my iPhoto Library on the MBP. I could then reconnect the external hard drive to my MBP and the iPhoto Library should reappear, shouldn't it?
Looking forward to more input ...

My Toshiba external hard drive is no longer being recognised by my Macbook Air - solution?

My Toshiba external hard drive is no longer being recognised by my Macbook Air. The light on the hard drive is on, but it won't appear on my computer's desktop or anywhere else. How can I fix this?

Hi rivraff,
If you are having issues mounting an external hard drive volume, you may want to see if it shows up and/or can be repaired in Disk Utility; you may find the following article helpful:

Adobe CS5 programs have trouble opening folders on external hard drives under 10.10.2

Just upgraded 2 mac's to 10.10.2. One is a late 2013 Mac Pro, the other is a lot-of-the line, BTO iMac 5K. (Processors and Ram are not an issue)
Both InDesign and Illustrator (CS5) are having difficulty opening folders on external hard drives. Mac Pro is connected to a 5GB LaCie d2 via thunderbolt cable, while the 5K is connected to a 2TB WD my book studio for Mac via FW800 with an apple branded Thunderbolt adapter. Both are formatted Mac OS Extended (Journaled)
Using the File>open command then drilling down to the selected folder on the Hard Disk drive, the finder sits blank with the spinning beach ball going.
Other local folders open up quickly and populate file lists with no problems.
Some folders on the external drive can be accessed through the File>open finder dialogue however they are folders that contain fewer sub-folders and files.
Update while typing this...
Both Folders that were giving us problems contained a shortcut. Hiding that shortcut inside anouther local folder seems to have cleared up the trick. This is a short term work around and I am wondering if Apple is aware of this issue or if others have found the same problem as I have and if this work around fixes their issues?

How long have you been running 10.9?
In my case the external drives go to sleep and have to wake up. Not much to do with Mavericks, just hardware sleeping to save energy. Note that 10.9 is much more energy aware and may put things to sleep more often. That may be a fair trade off

i tried transferring my iphoto library from my old macbook onto my new macbook pro (via external hard drive), but when i open the new iphoto, it seems to have transferred ALL images ever used on my old macbook. so i tried to just delete all those images so i could try a different approach to transferring, but the new iphoto won't let me do anything and every time i try to delete anything it crashes (since the image amount is so high). please help!!
MacBook Pro, OS X Mountain Lion (10.8.2), iphoto '11, version 9.4.2

To move an iPhoto Library to a new machine:
Link the two Macs together: there are several ways to do this: Wireless Network,Firewire Target Disk Mode, Ethernet, or even just copy the Library to an external HD and then on to the new machine...
But however you do choose to link the two machines...
Simply copy the iPhoto Library from the Pictures Folder on the old Machine to the Pictures Folder on the new Machine.
Then launch iPhoto. That's it.
This moves photos, events, albums, books, keywords, slideshows and everything else.
