The Real Abed

HDD's are cheap as dirt. And online backup sites work on Windows too. Either option is going to run you such a small amount of money it's crazy not to do it. You really need to get a backup because your drive is going to die. That message is usually a sign of the early stages of death. But not always. You can still use the drive, but you may going to have corruption as time goes on. Then again, it might just be a fluke. Who knows exactly how these things happen.Because I work mostly in a Windows environment and because HDDs are still relatively expensive, I've been slow on the uptake with making back ups. (Dedicating a drive strictly to HFS a new thing to me). Of course the time I finally decide to do it, the drive is out of reach. Figures!
I'm glad I have an old bootable Snow Leopard clone lying around, but now I'm having trouble with my old Mountain Lion dmg that I saved - it's failing to verify some pkg files. What a pain. lol
I just hope that, since I was able to format (and write zeros) to my hard drive, it means that the drive is healthy and I won't have to write it off. After formatting the drive, Disk Utility returned no errors when I tried to verify/repair it, but it'd be nice if there was something like chkdsk in Windows that surfaces the specifics of the drive. I don't even know if I have bad sectors on it or some other defect.
I have a family plan on CrashPlan which lets me have 10 computers with however many drives I want from each. With that plan, which is still pretty damn cheap, you could backup both your Mac and your Windows files AND download them to either machine from anywhere. CP has paid for itself for me. The iOS and Android apps are amazingly useful too as you can download any file your computer has backed up from anywhere. Useful for many file types like images and any video iOS can play out of the box.
Basically, you should easily be able to afford an online backup plan really.
Are your Windows and Mac computers the same machine or different machines? Because CP also lets you backup easily to another machine no matter what its format is. So basically on your Windows machine you could have a drive with NTFS or FAT or whatever and if I'm not mistaken, CP will be able to handle all the saving and storing of the files so you don't have to worry about OS X being unable to save to NTFS. This is actually a FREE feature of the program. I'd definitely check that out at least as it's free for local backing up. You only need to pay if you use their online feature. This would let you not have to dedicate a drive to HFS.
If they're the same machine, I'd still look into online backing up. Definitely recommended.
