Seagate 1T backup plus for Mac won't mount

I have a seagate 1T backup plus for mac which suddenly will not mount. I have done the disk utility disk repair and it says the volume appears to be OK. What do I do next?

likely a dead SATA bridge card.
see here:
Your dead external hard drive is likely fine! Great hope for your 'faulty' external HD
verify on another Mac first however
"backup plus" by the way is just a name, and designates nothing special about this HD

I just bought and backed up my computer and time machine with a "Seagate BackUp Plus for Mac". Now my time machine is empty. Panicked. can anyone help?

I just bought and backed up my computer and time machine with a "Seagate BackUp Plus for Mac". Now my time machine is empty. Panicked. can anyone help?

Lets start over...
Please restart the network.. shut down everything..
Restart in order.. modem.. router.. if different to TC.. or TC.. client devices.. wait 2min between each startup.
If the TC does not show up on the computer, in finder.. then we need more info.. what OS are you running?
Does the TC show up in Airport utility? Are you running wireless or ethernet?
If you still have issues.. plug the TC directly into the computer by ethernet.
Do a full factory reset of the TC.. and see if it now shows up.
Please tell us exactly what model TC it is and how old.. the A1xxx model number from the base will help if you don't know.
You take a screen shot of the TC opened in finder.
eg..
My TC is named Tardis4.. click on it.. and then open the data folder.. on this one called Tardisdata.
Then take a screen shot of it so we can see what the problem is.. screenshot.. with area selection.. control + shift + 4 .. the picture goes into the desktop.. and then you click the picture icon in the posting web page controls and select the picture.

Options for Seagate Backup Plus for Mac/Windows

I have a new Mac-mini (my first Mac since my original Mac 128), and just got a 3TB Seagate Backup Plus. It's so new, I haven't even read up on Time Macine though I assume that's the way to go.
I originally had in mind partitioning the Seagate with one HFS+ for the Mac and one NTFS for my Windows laptop (Win7) and old Windows desktop (XP). The latter is mainly for storing files in a place where it will be convenient to use them on the Mac. But with all the threads about partition and other errors, I'm wondering if that's not so wise.
The obvious alternatives are leave the drive as NTFS and find something other than Time Machine for backing up the Mac - or format it as HFS+, use TM to backup the Mac, and install HFS+ drivers at least on my laptop.
I usually like to try and research these sorts of questions directly, but with the learning curve moving to the Mac, and all sorts of other things, it would take me to next year to find my ideal solution. So for now, I'm just looking for suggestions on a backup strategy for the Mac that would, in addition to backups, leave space for manually archiving Mac files as well as exploiting the spare space on the external drive for some Windows purposes. (Not much videos, mostly photos, finances, and eventually my main reason for getting the Mac, ios development.)
Thanks for any suggestions.
Gary

Western Digital My Passport For Mac Won't Mount

Hello everyone,
I always try to find related articles prior to posting, but I haven't found anything quite like my situation listed. I have a "My Passport For Mac" that I recently reformatted on my Mac to use as a time machine (using 10.10.2). Prior to reformatting, it worked fine. I have it encrypted so any time I'd plug it in & it would request my password. All was great. I reformatted it & then used it to back up my Mac. However, days later, when I go to plug it in, the hard drive won't mount. A lot of folks with a similar situation are at least reporting that it's showing up in Disk Utility. However, mine is completely absent. I've tried it on multiple computers (including a PC). It's not showing up anywhere. But the disk is on & spinning. Does anyone have any idea what's going on? I'm stumped on this one. I'm not worried about recovering any data from this as it's just a Time Machine backup. I'd just like to get it to mount to my Mac again!
Any help would be greatly appreciated!
Thanks!

Historically, the problem has been that many USB-powered drives can't get enough power from a USB port after they begin to age. The Passport is bus-powered, getting all its power from a USB port. Not the best solution for a desktop computer.
To get such a drive going again, you need one of two workabouts:
1) a powered USB hub (has its own power supply to make up the shortfall) that goes between the external drive and the computer.
2) use a "Y" USB cable to get power from two USB ports simultaneously (such as http://eshop.macsales.com/item/OWC/USB2AYMBPB/)
Also, WD uses an odd proprietary formatting scheme that is of itself a problem area. WD makes very good bare drives but the enclosures into which they put them to make an external drive are not very good and not particually Mac-Friendly. The formatting makes them harder to use.
Once you get the files you need off the external, consider erasing and reformating it to Mac Extended Journaled using Disk Utility. That often makes the drive more reliable without having to revert to USB hubs or special cables. It gets rid of the proprietary formatting that seem to contribute to the problems.
I have three external drives. All have WD bare drives inside but none are in WD encosures. By far the best enclosures for Mac external drives are those from OWC:
http://eshop.macsales.com/shop/firewire/1394/USB/EliteAL/eSATA_FW800_FW400_USB
I have two of the desktop model shown and one of its portable version for my MacBook Pro. All three have given me superb service and zero problems.

WD My Passport for Mac won't mount on my Mac Pro

My 1TB external hard drive is less than six months old and was working fine; now won't mount on my Mac. I don't remember disconnecting it without ejecting it but I do think I got a message about needing to eject before disconnecting. I checked in the forum for a possible solution and tried connecting it to a PC laptop; I could see it to eject it but it didn't show up anywhere else. I am not a computer expert! How can I access my files? I have a Mac Pro, Mac OS X ver. 10.6.8.

I bought a Seagate Backup Plus (Windows & Mac) but the specs don't mention FireWire 800...is this only with the Mac-only Backup Plus?

I bought a Seagate Backup Plus (Windows & Mac) external hard drive. The specs don't mention "FireWire 800"...should I return it for the Mac-only and does that have a FireWire 800 update that I saw mentioned on the Seagate site for Backup Plus?

Seagate Backup Plus only comes with a USB 3.0 connection, not FireWire. To use it with FireWire 800, you have to buy a FireWire cable for the external disk. Select "Accessories" > http://www.seagate.com/external-hard-drives/portable-hard-drives/standard/backup -plus/?sku=STAE102

Acrobat Pro 9 for mac won't launch, reloaded from disk when hard drive needed to be replace. It's in applications folder but there is an X on the Acrobat Reinstall icon. What should I do.

Hi Janice,
What version of Mac OS are you using?
Adobe does not recommend migrating the software from one disk to the other.
Please run the setup file for Acrobat and reinstall the software. You might want to delete the existing version of Acrobat installed before reinstalling it.

Apple physically replaced the HD on my Imac. I backed up everything on a Seagate Go Flex Desk for Mac external drive for Mac. I went through the motions to restore my Iphoto Library back to my computer. Can't find them!!!!!

Apple replaced my hard drive on my Imac. I'm lucky I backed up everything on a Seagate Go Flex Desk for Mac external drive via Time Machine . I followed directions in order to restore my iphoto library , but I can't seem to find it on my computer. Are the files locked?

No reason to assume they are locked. The library will be restored to the location it was backed up from, unless you specified somewhere else. Have you looked in your Pictures Folder?

Video won't run. telling me to update flash player. click on update for mac won't load?

video won't run, telling me to update flash player, click on update for mac won't update. do i need to load flash player and is it ok for mac?

Yes, it's fine for your Mac ...
Most sites such as YouTube require the Flash plugin.
Flash isn't a player per se, but a plugin.
Sometimes uninstalling the current plugin then reinstalling new can help.
Troubleshoot Flash Player | Mac OS
Make sure and uninstall the old plugin first then restart your Mac.
If you use Safari to view videos, from the Safari menu bar click Safari > Empty Cache
Now try a video.

Re: Online Backup Services for Mac?

pc users have online backup services such as carbonite to choose from. Is there an equivalent backup service for Macs?
My pc friend says he pays $50/year for his online service which makes more sense than having an external drive next to your computer. Good when your hard drive craps out, yes, but not so good if both get damaged due to fire, water, etc. or disappear due to theft.

There are a few, but I have only been experimenting with .Mac so far (which mostly for the other features). You can do a search for : online backup for mac : and several show up. I have heard good things from others about Mozy. Note the file transfer for any online service will be limited by your network bandwidth and availability.
Others may have specific recommendations.

Elements 8 for Mac won't launch

I just installed this program and it won't launch when double click the icon. This is a brand new laptop so the sys are current. Any ideas?

Barbara,
Thanks for the help, but I'm embarrassed to say that my problem was the fact I was double clicking on the icon instead of single clicking. I've only had this machine a couple weeks and old habits are hard to break.

Then I would do this. Uninstall it (there's a link to the uninstaller in the PSE 8 application folder), and then create a new admin user (system preferences>accounts), log into that user and run the install from there. Be sure to repair permissions afterwards. If all is well in the new account you can log back into your existing account and delete the new one.

Hi Patrick,
Can you please mention the version of Adobe Acrobat that you are using and on what OS version. Also mention whether this problem has started recently and was running fine earlier or is it a fresh install and has never worked for you.
Have you tried uninstalling and reinstalling the product after you started facing this issue.

My Mac won't mount my external HDD after installing Lion - What can I do?

My Mac won't mount my external HDD after installing Lion - What can I do?
HDD: Verbatim 3.5'' External HDD eSATA & USB 2.0 #48802
I can not find it in Disc Utilities - so I can not repair it.
I also haven't found any Driver for the HDD to do an update.
My Mac is running on the most recent updates of OS Lion.
The HDD worked before. It contains my former Time-Mashine Backups. I would like to use this drive again. It isn't very old yet.
It would be much appreciated if anyone could help.
Cheers,
Yves

OK, try restarting in Safe Mode and if that doesn't work try resetting the SMC and PRAM.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Hi Judy,
I find Optical Drives short lived, especially on Macs, but have you tried a CD Cleaner Disc?
One other fix in 10.4.x...
First, Safe Boot , (holding Shift key down at bootup), use Disk Utility from there to Repair Permissions, test if things work OK in Safe Mode.
Then move these files to the Desktop...
/Users/YourUserName/Library/Preferences/com.apple.finder.plist
/Users/YourUserName/Library/Preferences/com.apple.systempreferences.plist
/Users/YourUserName/Library/Preferences/com.apple.desktop.plist
/Users/YourUserName/Library/Preferences/com.apple.recentitems.plist
Reboot & test.
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.
