virtualbox.org

I have a seagate 250gb hard drive and virtualbox can't seem to detect it... everytime I plug in the external into my mac (yes, I have a mac don't complain about it) it shows up as grey and I can't access it.
I tried other methods such as unmounting the external and then letting virtualbox detect it but it then gives me an error message and I have to forcefully stop the virtual machine.
Any insight on this?

By the way, I have two partitions on my external hard drive, one is empty; theres nothing on it. this is the partition that I'd like to put stuff on... the other has files and other random crap on it (and no I'm not willing to combine those two partitons because i don't have enough space on my hdd to put it all)

Thanks y'all!

Did you try a USB filter, specific for the device or empty?

Partitioning software has had support to grow partitions for a long time. You can remove one partition and enlarge the other without data loss.

I install the guest additions for virtualbox plus the usb filter. None of those worked. I'm pretty sure its because that virtualbox detects the external as one large partition rather than two separate ones that I'm getting this problem.
So how can I combine two partitions without losing data?

Use a partitioning software for your host. This has nothing to with VBOX.

No, VB just sees a storage device. It doesn't care if it has one partition, no partitions at all or 100 partitions. It's still one device.

Guest Additions won't help, they do nothing with USB. Installing the ExtPack on the Host however might help, since you'll be able to use USB2 on the Guest. But do you actually see the device disappear from the Host when you try to attach it to the Guest?

Actually, I can't attach it at all. It appears as grey and it doesn't disappear either. I tried unmounting it from the host and then letting the guest detect it, but it gave me an error message

Ok, in the TS you said you have a Mac, your profile states the OS is 'other', which OS is it exactly? You may want to search this forum for other users that have issues with their OS and USB, you may find a solution.

I forgot to update my profile. I used to use linux...
I just got this mac like a couple of weeks ago.
By the way, my partitions are exFat. Should I change them to NTFS?
Can virtualbox detect exFat?

VB doesn't care about the file system. For your Host now, add your user in the vboxusers group, as noted in the User Manual and VirtualBox FAQ.

Actually, I got it to detect the external with windows 7 from bootcamp so I'm good for now
Got portable windows 8 on my external now

Ok... I answered too early.
I thought I was gonna get windows 8 portable, but... when installing virtualbox keeps on crashing
apparently I only used 2gb ram and its can't do anything on windows 7 32bit so, I've got two choices:
1. get windows 7 64bit, burn it to a disk and upgrade from 32bit
2. find out how to let virtualbox on mac detect my external

I'll go with the second option for now as windows 7 64bit downloads.
And I'm back where I'm started *sigh*

whoops. sorry for double posting. I'm really mad right now so I didn't notice

So, with Linux, did you put your user in the group?

Never mind.... I got it working on another forum and windows 64 bit is finished downloading
