However whenever I boot into a Linux Distro and when I connect my external Hard Drive and I am able to see both my external hard drives, what could be the reason for Windows not showing me my 2nd External 2 TB Hard Drive?

This question came from our site for system and network administrators.

Do you just not see an expected drive letter? Do both drives appear underneath "Disk Management" under "Computer Management"? – ziesemer Dec 26 '11 at 1:32
Both the drives appear beneath computer management, this issue is not restricted my PC its the same on my friends PC. – Pratik Dec 26 '11 at 1:51
I have both External's from WD, so when I connect there is this virtual disc drive that it mounts to install its software, I get both, one for each external, but not my HDD. – Pratik Dec 26 '11 at 1:53
If you connect only the 2nd drive, is it then visible to Windows? – Harry Johnston Dec 26 '11 at 3:37
No it's not if I connect both of them I can see one but not the other, but if I connect both of them individually by not connecting the other both of them are recognised by windows. – Pratik Dec 27 '11 at 4:22

As both drives appear under Computer Management, you should just need to right-click the one that isn't yet assigned a drive letter, then select "Change Drive Letter and Paths", then "Add..." - and assign it a drive letter.

Thanks, I'll try that. – Pratik Dec 26 '11 at 2:04

What filesystem and partitiontable is on the drive? if it does not show under windows, but does under linux this is a good sign for a non ntfs or fat drive, or even one with a special partition table not recognized by windows.

you can check the partition table type table with parted under linux

 parted /dev/sdx print

choose your drives id here (not partition id).

the filesystems are not 100% correct, but their type should also give you a clue.

They both are on NTFS that's not a problem, because if I disconnect the hdd which windows recognises and reconnect the one which wasn't detected by windows I can see my HDD show up again. – Pratik Dec 27 '11 at 4:20
