I've plugged an external hard disk on my computers. The device has been detected, but isn't shown on explorer. It is the same situation on both windows 7 and windows 10.
Detected / installed because it was shown in control panel > Devices and Printers. Also because I've found it using the list disk
command line and it should be the Disk 1
:
Microsoft DiskPart version 10.0.10586
Copyright (C) 1999-2013 Microsoft Corporation.
On computer: TOSHIBA-MINCONG
DISKPART> list disk
Disk ### Status Size Free Dyn Gpt
-------- ------------- ------- ------- --- ---
Disk 0 Online 238 GB 0 B *
Disk 1 Online 465 GB 127 MB *
Unrecognized because it seems that the Partition 2
has unknown file system type. So it cannot be recognized by windows.
DISKPART> select disk 1
Disk 1 is now the selected disk.
DISKPART> list partition
Partition ### Type Size Offset
------------- ---------------- ------- -------
Partition 1 System 200 MB 20 KB
Partition 2 Unknown 465 GB 200 MB
Can somebody help me to resolve this problem without clean the data in the hard disk ?
Update
I tested the hard disk format type on OSX. And its type Apple_HFS
as you can see at /dev/disk2
.
Air-de-xx:~ xx$ diskutil list

diskmgmt.msc
look like?diskmgmt.msc
. It is restricted by a strategy. I need to call an administrator to do it. Let's give up this question and move on if you don't mind. @BenN
