I doubt updating the BIOS would help (if the drive was working properly in Windows 8.1 previously), but it's probably worth a shot, just so you could rule it out. If there's a problem it could manifest in different ways, including very short interruptions (which may be enough to disrupt a drive access in progress, causing the error message, then regaining the operating speed quickly enough so as not to trigger a disconnection/reconnection from/to the system). The easiest way to try and confirm is to try and listen for it spinning down and up. That pop-up about Windows discovering the drive does sound like it could have spun down then back up again, which would be indicative of some kind of hardware problem. Would updating the BIOS have any effect? I have a ASUS Maximus Hero VII. I may just go ahead and buy a replacement drive. I did have a temporary pop up from Windows showing that it had just discovered the drive. Check that the External disks option is enabled. There’s a simple fix for this: Open a Finder window.

In that case you could possible try removing the side panel from the case and listening for the hard drive spinning down/up around the time when the error(s) show up in the logs. a motor or power problem), which is causing it to spin down and the system is throwing an error because it was trying to access it. a computer with a smaller hard drive, and had to work off of an external hard drive.

Select unmountable external hard drive and click 'Next' button to scan all lost data. When this happens, the drive can leave behind a 'ghost' folder in the /Volumes directory, even though the drive is no longer mounted. Look in the column on the left to see if the hard drive appears there. This issue is typically caused by a drive that didn't cleanly unmount (for example, due to a power outage, the drive disconnected without ejecting). You could try going into your power management settings and setting the hard drive never to power down, as a diagnostic measure.Īlternatively it's possible that the drive is failing (e.g. Step 1: Recover lost data from external hard drive that was accidentally unplugged on Mac. Find Disk Utility by opening Spotlight (cmd+Space-bar) and start typing Disk Utility, press enter to open the program. My first thought is that perhaps some bug in the power management of Windows is causing the drive to power down while some service or application is attempting to access it.
