Greetings all! I have a dead 10 year old mac that I need to transport data from. OSX 10.7 to Windows 10 64bit. This is my first attempt to do this across operating systems. The hard disk drives in question are 2 500GB drives with SATA data and power connections. I'm curious to see what techniques you might have used. I'm planning on dumping all data onto a working MacBook then transferring it to an external drive. External drive to PC. Easy right?

My concerns:
1)Any formatting issues I should be aware of?
2)Any hardware I should avoid?

Anything I'm missing? Please let me know.

Please and thank you everyone!!

OS X uses HFS+, and can read NTFS (Windows) but can't write to it.
Windows uses NTFS, but can't read nor write HFS+.

So to use an external drive to share files between OS X and Windows, format it as exFAT. It shouldn't matter which OS you use to format it, but I've heard it works better if you format it under Windows. Do a trial run copying some small files first to make sure it's accessible on both OSes, before you spend several hours copying 1 TB of data.

If you want to plug the Mac drives directly into the Windows computer, you'll need a Windows program which can read HFS+. HFSExplorer can do this (read only).

Paragon had a HFS+ driver which could read/write HFS+ on Windows 8.1 and earlier. I'm not sure if it works on Windows 10. Also, an earlier version of this driver had a serious bug which could randomly corrupt your entire HFS+ volume when writing files to it. So I'd use it only to read files.

The other option is to connect the old drives to the Macbook, plug the Macbook into your LAN, and copy the files to a Windows shared folder over the LAN. This is the most straightforward way to do it, but I don't like it because OS X writes a bunch of .DS_Store files everywhere. HFS+ supports more file metadata than NTFS, and OS X's way of preserving this extra metadata on Windows shares is to store it in these .DS_Store files.
