Question: I have both  windows 8 and OS X Mountain Lion . Can I backup both of them at the same time on it?
Document: MAC/PC: I have the 3TB model and have filled it up half-way with videos and music. It works flawlessly on both Mac OS X Lion and Windows 7. Although it doesn't have a USB port, you can transfer files using a direct connection between your computer and the drive via Ethernet (>10mb/s) or wireless (~2mb/s).
Great product, works like a charm by backing up my files on both MAC (OS X Lion & TimeMachine) and Windows (XP SP3.) Not only can I access all of my files (pics, music, videos, docs, files) from my &#34;smartphone&#34; - S3, I can even access them on my &#34;smartTV.&#34;- Samsung UNES8000TV  .
I purchased this product to back up 3 of our laptops and 1 desktop. My computers consist of a Vista machine and Windows 7 32 bit and 64 bit machines and a Mac OS X Lion. I have had zero problems with the My Book Live 2TB unit. The only problems I ran into were IP address conflicts on my network, which was an easy fix, and my router had timed out on me for some reason preventing the first Mac OS X Lion back up to complete.
Otherwise great specs & it is a great network drive. Backed up 1st Win7 laptop using SmartWare fine but 2d one never completed initial data set correctly. I bought it specifically for TimeMachine backup w/OS X 10.8 on a late model MacBook Pro. WiFi backup was extremely slow (over 4 days for 250GB) and then got Verification Error messages after 15-20 days. Switched to Ethernet & initial backup went much faster but never got more than 28 days before it errored out again & required new backup.
Don't buy this product. First off, this product has been the bane of my existence since I received it. Not only did I have many problems getting it to work, it is incredibly slow and takes at least 2 weeks if not more to back up about 200 GB. Moreover, I think there are problems with compatibility with the new Mountain Lion OS on Macbook Pro.
I'm using this device as a backup drive for my Mac (via Time Machine) and also for its data sharing capability.After installation, I setup the share with my desired credentials. All good. I tried to use Time Machine, but Apple had modified the protocol used in MacOS Mountain Lion; no problem - I updated the devices firmware via its web interface, and the device then worked for Time Machine.I have been using the device for a couple of weeks.
I got this to use as a backup drive for my Macbook Air (OSX Lion). After the firmware updates that enable you to use this with this OS, time machine worked for a few weeks. But suddently, I got the message: "Time Machine completed a verification of your backups. To improve reliability, Time Machine must create a new backup for you. Click Start New Backup to create a new backup. This will remove your existing backup history. This could take several hours.
I used this to backup my macs with mountain lion and everything went smooth, it works perfectly and barely takes up any space.
It has never dropped from the network. Both Windows 7 and Mac OS X easily discover and use it.Other people have reported problems in the Amazon reviews, but I haven't experienced any. Perhaps the earlier firmware versions had problems.The only downside is that some non-technical users may have trouble configuring this device; it's a little bit involved, and required the user to be able to setup shares and credentials through a web interface.
This drive works very well with 32 bit Windows Vista and OS X but it crashed my 64 bit Windows Vista laptop. I'm still trying to fix it. If you need a cloud drive for storage, it works great on 32 bit computers. Stay away if have a 64 bit Windows OS.
Answer: Yes you just have to make sure that the drive is in the proper format, FAT32 is the format that will allow you to read a nd write on both OS's that you have.
