Since upgrading to OS X as few weeks ago I cannot connect my external hard drive (Maxtor 320GB). Error message "Disk Not Ejected Properly" - so I can no longer backup using Time Machine. Found loads of posts on the web for this but nothing clear to resolve. Last post I read was referring to "spotlight" ??
Can anyone advise - note: I'm fairly new to MAC's!!
Mac mini, OS X Yosemite (10.10.3)
Does the USB port read/write other external HDs?
Try another USB port and cable.
Try resetting the SMC and NVRAM/PRAM

Which make and model (USB, FireWire, portable, desktop and so on) is your Maxtor external hard drive...?
Most times that problem is caused a bad cable or a weak cable connection, but it could also be caused by a failing hard drive or a failed control chip in the enclosure itself.
What I would probably do is get another good quality external hard drive to start a new set of TM backups on. Then go back and try to sort out the problem(s) with the old backup drive.
Maxtor Basics Portable Storage (PN-9KM2DG-500). Probably 4-5 years old. Had been used as a backup drive for a PC. I had (about 1 year ago) re-formatted and started to backup via TM with no problems. Then I upgrade to the latest version of OS X.......
When the Maxtor cables are connected (to switch no the drive) the HD disk is temporarily displayed on the desktop. Temporarily I can see backup files. Temporarily the TM backup starts. I guess it could be the leads (cables).
...I've just changed the cable....... Seems to be connecting and backing up. A easy fix but thanks for the suggestion.
External drive now not connecting
