Target disk mode, mac to pc, missing drivers?

684 35 February 13, 2018 at 11:54 AM
I don't work with macs and this has been eating up my entire day. We are trying to use the target disk mode to plug a macbook pro into a windows pc to access the drive over usb. I have been able to get into target disk mode (it's just hold down T) but the windows pc shows it doesn't have drivers for the hardware. This isn't an issue reading the mac format, I have software for that. The issue is windows 10 seems to not have the driver to load the hardware in the first place. There isn't a lot of info online about going from mac to pc but some people have said they do it. I thought I had seen someone say I needed the SD card reader driver from bootcamp to make it work. I found that and got it installed but no change. Does anyone have any experience with target disk mode to a windows pc?

Apple uses different file systems which windows doesn't support.

To do this you'd need to buy http://www.mediafour.com/software/macdrive/

Differences in the file systems could still cause issues. If you just want a backup of the machine in target disk mode you can do that with other disk imaging software, but you won't be able to access the lies easily on a pc.

Apple supports SMB/CIFS, boot the mac and plug an ethernet cable between the computers change network settings as required.

Why were you putting it in target disk mode in the first place?

I am well aware that a Windows pc can not normally read a Mac hdd and already stated I have software for that. The issue is the hardware being recognized as a hdd in the first place. Until that happens it won't matter if I can read the content or not.

The system's drive is chips on a motherboard so I can't pull the drive and clone it like I normally would. We are trying to get a copy for forensic reasons. I can't boot it up and log in without altering it.

You can boot to diagnostics or macOS recovery (I forget which, but I'm thinking recovery) and actually launch disk utility (it's in the menus at the top) and image the drive to a usb drive.

If you have access to another Mac, you could also use disk utility on that machine to create in image of the drive of the machine in target disk mode.

Does target disk mode actually work over USB? I know it works over Firewire and Thunderbolt but i'm not sure about USB...
It would have to be USB-C on both computers if USB was going to work.

The only issue is I don't have any usb C devices I could back up to from the Mac. I'll have to see what I can come up with. Thanks.

I know older macs only support TDM over thunderbolt and firewire.

I think you're going to have to use macOS recovery & disk utility or another mac.

Disk utility worked perfectly. Well except for when it said it couldn't format my external hdd because there wasn't enough free space. But anyway I got the image and we can read it just fine on a pc. Thanks for your help.

Glad it worked. I probably would have imaged to a dmg file rather than a partition but it doesn't really matter.

It was a dmg file. First it said it didn't have permission to write to my external hdd. I assume because it was ntfs. I told it to format the drive to exfat and it gave me the nonsense error about not having enough space. I did the format from a different pc and then it wrote the dmg just fine.
