Why is is that makers of PC hardware think they can also write PC software?
Case in point, a Seagate GoFlex 3TB hard drive I recently bought. I got this one because I needed a large external hard drive urgently, and this was the only 3TB one in the shop.
Unfortunately, once I'd installed the accompanying software on my Mac the problems started.
- Time Machine backups froze every 50GB or so (which is really annoying when you've 1.5 TB to back up)
- Finder crashed hard every few hours
Both these things required a reboot.
It turns out there's a known problem with Seagate's software - see for example here.
- Go to your Applications Folder and locate the Seagate Diagnostics application. Delete it by moving it to the Trash. Finder will ask you for your password. Provide your password and the app will be placed into Trash Can.
- Go to hard drive and open it. Go to the Library Folder and open it. Go to the Application Support Folder and open it. Locate a folder called Seagate. Delete the Seagate folder by moving it to the Trash Can. If OS X asks for your password, provide it. The folder will be placed into Trash Can.
- Close the Application Support Folder. Go to the LaunchAgents Folder and open it. Locate the com.seagate.SeagateStorageGauge.plist file and delete it. Again, OS X may ask you for your password.
- Close the Application Support Folder and then the Library Folder. Open the System Folder, then open the Library Folder. Locate the Extensions Folder and open it. Locate the Segate Storage Driver.kext and delete it. OS X will ask for your password again. Close all folders. - Reboot your Mac.
Frankly, installing a kernel extension to show some extra lights on a peripheral stinks of bad practice.
I'd advise anyone not to buy a Seagate drive, but if you do - don't install any Seagate provided software on your Mac
