5tb hard drive for MAC and PC

SteveButabi 322 82 March 18, 2016 at 06:21 PM
I bought a 5tb WD drive a little while ago and Im trying to format and partition it to work on my macbook and pc. But I cannot get it to work on the Macbook. I have tried partitioning it all to 1 partition and breaking up into 2tb, 2tb, 1tb but still wont work. I formatted it Exfat also but still no dice. Anyone have any advice?

You format individual partitions not the entire drive. I suspect it has to do with the settings/software you're using to partition the drive. For partitions >2tb you need to use GPT.

You could try partitioning / formatting the drive on the mac using disk utility. It may force you to format as HFS+ but you can reformat on the pc. Be careful, it's actually possible for gpt and mbr partition tables to exist simultaneously on the same drive which can cause some big problems**. I recommend you delete all partitions via windows first. Also note some versions of windows won't automatically mount exfat unless you change some settings.

**could have been apple partition map and not gpt.

I cant get the mac to see the hard drive at all anymore. I have unpartitioned the drive and the mac still wont see it. I also tried NTFS with 1 volume (5tb) and the mac wont see it either.

Try formatting/partitioning it using disk utility on the mac. Go to the "Go" menu and choose utilities.

If I go into Disk Utility it only shows my internal SSD drive. Not the External. I have seen it in there in the past but I havent been able to get it to show up in a long time.

If the drive doesn't show in disk utility see if it shows in system profiler. If it doesn't show there it's not going to work on your mac.

Is it USB powered or does it have an external power supply?
