Mac-formatted USB drive not recognized as Mac OS Extended with Parallels 10/Windows 8.1

Mac-formatted USB drive not recognized as Mac OS Extended with Parallels 10/Windows 8.1

I formatted a USB thumb drive on MacMini 1 as Mac OS Extended (Journaled)

Plugged formatted USB thumb drive into MacMini 2 running Parallels 10 / Windows 8.1

Windows asks if I want to format drive.

How do I get MacMini 2 OS X [10.10] to recognize USB drive with Parallels/Windows running?

It is a different format than Windows (which is why Windows asks). There should be a setting in Parallels to manage removable devices in the Windows guest machine. Turn off USB in the Windows Guest setup and then MAC should own the USB drive.

If you want to use it in Windows, you will have to format it using exFat, Fat32 or ntfs. Fat32 has a max filesize limit of 4GB, so that file-system is rather limited. If your MAC OS can read and write to ntfs, I'd use that. Older MAC OS's couldn't use ntfs without 3rd party software, newer versions though might be able to use it.

Newer version can read NTFS, but you'll need to enable write or buy 3rd party software to write to NTFS.

Windows can read and write Mac HFS+ partitions with 3rd party software.  There is no way to read it by default.

My goal is to get MacMini 2 OS X [10.10] to recognize [read/write] external USB drive, formatted as Mac OS Extended (Journaled), drive as a Mac formmated drive with Parallels/Windows running.

The issue is the USB drive is currently formatted as Mac OS Extended (Journaled), is recognized [and can be used to read/write] by MacMini 1 & 2 OS X. I do *not* want to use this USB drive with any version of Windows.

In Parallels 10 there is option to have external drive connected to Mac when installed. This does not work.

When I plug Mac formatted USB drive into MacMini OS X with Parallels 10 & Windows 8.1 running, it appears  to be recognized as a Windows device and asks if I want to format drive - I assume as Windows format as it is already formatted for Mac OS X.

Again, I want to use this USB drive to read/write Mac OS X files, with Parallels 10/Windows 8.1 running *not* Windows 8.1 files.  Hope all this is clear...

Doing so - 'Eject' in windows 8.1 - does not allow USB drive to be recognized in Mac OS X.

Here is a Parallels Knowledgebase Article that deals with disabling the USB device in the guest machine.

See if this helps. It should. I keep removable devices disabled in VMware unless I want them.

You need to install HFS+ utilities on the Windows partition to read the drive in Parallels when you do it that way.  It just passes the USB device through.  It does not convert HFS+ into NTFS for Windows to read.  It's also not a share.  It's just the USB device.  If you didn't install HFS+ utilities, then you won't be able to read HFS+ disks.

You should create it as a share from your Mac and connect to the share if you want to keep your drive formatted as HFS+.  NTFS is a more widely used file format, so I keep my external disks as NTFS for my Macs and they show up just fine in Parallels.

Parallels normally starts off by asking you what to do with the USB device when you first use it.  You must have, at some point, told parallels that you wanted it connected to Windows.  Follow the instructions on the link that John Hurst provided and, in step 3 choose Connect it to my Mac.

The USB drive was initially formatted as FAT32 (maybe NTFS?) when used with Windows 7 PC. When I first connected drive to Mac OS X running Parallels 10/Windows 8.1, I realized formatting was wrong, so I reformatted to Mac OS Extended (Journaled) on another Mac OS X only.

Then I reconnected to Mac2 running Parallels 10/Windows 8.1 - here the problems started as above. I knew about the Parallels article http://kb.parallels.com/ca/111725 and how Parallels would ask for disposition. However, the current setup only recognizes USB drive as Windows formatted.

However, I have other options: use USB drive from networked Mac and research Parallels KB.
