I have a WD 500gb portable hard drive (My Passport series) that I bought about a year and a half ago. It's served me pretty well for the most part, but this past week I started getting cyclic redundancy errors when I tried to download to it. This was only happening for some downloads and not others, so after a little googling, I figured that I probably had some bad sectors and I would need to reformat it. So last night, I backed up the important stuff and started a full format. I should probably mention that I'm using Windows 7, but on an older laptop that doesn't really do anything fast.

I left it for a couple of hours last night, but it wasn't really moving and I thought it might have frozen, since like I said, my laptop is pretty slow. I canceled the format, pulled out the drive and reconnected it, and tried again, leaving it overnight this time. I kept an eye on the bar for a bit before bed, and it moved up to maybe around 5% (no actual percentage shown) in the first hour or two, so I left it on and went to sleep. When I checked it this afternoon (12+ hours later), it had barely gone up overnight, if at all. So I cancelled, disconnected, and retried.

That was about 5 hours ago. Once again, it moved up to around 5% in the first couple of hours, but as far as I can tell, it hasn't moved at all since then. Am I being impatient? Did I screw things up by stopping the format before? Should I just break down and buy a new external, or is there any way I can salvage this one?

Any help or advice would be appreciated!

Edit for specs: Laptop is Sony Vaio, model # PCG7L1L. Can't find an exact model number on the drive, but it's an older model WD Passport, 500gb, USB 2.

My feeling always in these situation is that it just isn't worth it. You could try the Data LifeGuard tools from Western Digital support, and a zero-fill may be successful. But once a drive has started throwing CRC errors, it isn't going to get any better, and that means you can't trust the drive to remain reliable in the future.

Thanks. I think I'm going to try the zero-fill for now, but I'll start shopping around for a new drive. I've been wanting more space anyway. Oh my poor wallet...
