Windows 10: Hard drive only showing 4gb of unallocated storage when its 4TB?

I took out a 4TB hard drive out of my imac from 2013 that had Linux on it. I plugged it into my pc and its only has 3.86GB of unlocated storage. so i tried to use some software to find any hidden portion but it showed nothing. is there any way to clear my hard drive. I have used the hard drive recently so i know its working.

4TB hard drive not getting all space available

Hey guys,

I have a 4TB hard drive that used to be plugged in to an old PC that only read it as being 2TB, now it's on a newer computer, but it will still not show as 4TB, it doesn't let me resize/expand it in Disk Management, I deleted all the partitions in it, but it shows as 2 unallocated space instead of 1.

What can I do so it recognizes it as 1x4TB hard drive?

Thanks.

 

Hard Drive Storage

I have a 500Gb Hard Drive, running Windows 10 Pro version 1909. My c drive is nearly full, I have checked every area on the pc and nothing adds up to the 486Gb I'm supposed to have available. I have gone to Settings > System > Storage - it shows that 401Gb
is being taken up by Apps and features but when I click on this and show the list of installed apps with their sizes, I have added up the entire list and it comes to 25Gb total. It doesn't show what's eating up the rest of the 400Gb of space. I have deleted
everything I can and have only been able to free up 11Gb so far so my c drive is still showing red. At this point is the only other step to reload the pc, or does anyone have any suggestions as to what it might be and how to fix?

Thanks,

Heather

 

New 4TB Hard Drive Read As 1.6TB

The 4TB drive only shows 1.6TB, there always are two reasons for that:

1.The 4TB hard drive has been initialized to a wrong partition table. If you find a formatted hard drive not showing full capacity, which is mainly because you format the
4TB hard drive to MBR partition table. As we all know, MBR partition table cannot address to the space that exceeds 2TB. As a result, to use a full capacity of a hard drive that is larger than 2TB, you need to initialize it to GPT partition table
via
an MBR to GPT converter.

2.The 4TB external hard drive does not connect correctly. Some portable hard drive and USB hard drive are designed to connect a PC via a USB port. If you install the USB hard drive to your computer, the hard drive capacity detecting may
become an issue. An accepted explanation is the controller board of USB hard drive breaks the 2TB limitation, yet Windows internal device controller does not. Therefore, you need to additional hardware to make the installed USB/portable hard drive showing
full capacity. In that case, all you need to do is connecting the 4TB USB hard drive via USB port.
