Hello,
I am doing a data recovery on someones's Mac hard drive. My intention is to recover the data and transfer it onto their external hard drive. The external hard drive has 1TB of storage. However, when I go to plug it into my Windows 7 Home Premium computer, it won't show up. It does however show up under disk management as an uninitialized disk. I did initialize it after seeing this, but then it shows that it is unpartitioned. I don't want to partition it, because the person already has data on it and it will be erased if I do. Is there a way to use the external hard drive without losing the data on it?

I'm not sure if initialization would remove the Mac format. Your best bet now would be to go to a Mac store and explain what happened. The only other alternative is to find someone with a working Mac, put the hard drive in question in an enclosure and try to mount it on a the Mac.

Fast one

You can't read a Mac hard drive on a PC without special software. The Mac uses HFS file system while the PC is NTFS. Here is a url for one software package:http://www.paragon-software.com/home/hfs-windows/
The better solution would be to use another Mac. There are lots of utilities to do what you want.

Just to clarify, we are talking about the external hard drive, right? The hard drive that needs the data recovery is an internal hard drive. The hard drive in question is the external one. If I already initialized it on my Windows pc, would that have deleted anything off of the external hard drive?

NO matter what you do, DO NOT format, initialized it. By partition it you change the drive ability to read in MAC.

You can use r-studio.com to copy the data to a new HDD

Good luck

I went to someone that had a mac and was able to find the external drive and its data on it. The internal drive was beyond saving. Thanks for the advice.
