Each works with other types of peripherals and other external hard drives. I've tried both USB ports, neither seems to work. Brought it over to the MBP, and it still will not recognize. But it worked and is recognized by the iMac.
I formatted the drive on the iMac to use the recommended Apple system (journaled), although for some reason it made me partition it into two. The iMac recognized the drive immediately, and prompted to use as a Time Machine. I did some research and it sounds like others have had a similar problem recently, so on a whim I brought it over to my old iMac, which is still running Snow Leopard. This morning, it still wouldn't read on the MBP. I spent last night reformatting on the PC, and it shows as a blank drive on my ThinkPad. It does not appear in Disk Utility or in System Profiler. However, whenever I connect to my MBP, the drive just makes a spinning noise and gives no indication of being read by the machine. The drive works fine, and I've run numerous diagnostics when connected to an old ThinkPad. It has a capacity of 750GB, and I would like to use as a Time Machine for backing up. The drive is an ioSafe "rugged portable", which runs off USB (and doens't plug into the wall). My new Macbook Pro (late 2011, running Lion) won't recognize my external hard drive. As well as check out a simple walkthrough over on MacWorlds website on formatting a Mac boot disk.Looking for some advice.

They must be reformatted to Mac OS X Extended (Journaled) disk using a GUID Partition Table. WARNING! This process will ERASE the USB thumb drive, so you can't have anything on it!įor El Capitan the command line would be as follows, where MyVolume is the name of your USB disk: sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia -volume /Volumes/MyVolume -applicationpath /Applications/Install\ OS\ X\ El\ Capitan.appĪlso note that FAT formatted drives will NOT work as a Mac OS boot disk. Use the createinstallmedia command in Terminal to create the bootable installer.Open the Terminal (which is in the Utilities folder of your Applications folder.).Mount your USB flash drive, or external drive with a 8GB or larger partition.Quit the installer if it opens automatically after downloading. Download the OS X installer from the Mac App Store.As long as you have that, here are the basics: You will need a running Mac system and a blank USB Thumb drive (at least 8GB in size). You need to create a boot installer disk to setup a new disk as an internal boot disk for a Mac. If they are indeed unformatted, how the heck am I supposed to format them when Disk Utility can't see them at all? I don't have an external drive available, but I suppose I can wrangle one with some shenanigans. Is it possible that these drives are shipped raw and totally unformatted (first was Seagate STBD1000100, SATA III, second is Western Digital WDBMYH0010BNC-NRSN, SATA II)?

I was thinking that these drives just needed to be formatted, even though both indicated they were Mac compatible, which I presume means pre formatted in FAT so both Mac and PC could read them. So I got a new drive, same capacity, different brand and same result: I don't see the drive in Disk Utility at all, no matter how I boot. Bad drive right out of the box, yeah? Rare, but it happens. What's more, I repeated all of these steps on a different Macbook, and the results were the same there - drive not seen. Booting from Internet Recovery is the same. In DU, I can see the thumb drive, but I can't see the new hard drive at all. I popped the bottom case, discharged any static, undid the screws on the drive bracket, pulled the old drive and installed the new drive.Īfter putting the Macbook back together, I booted from a USB thumb drive and launched disk utility.

I have a 13.3" mid-2012 2.5 GHz Macbook Pro and wanted to upgrade the internal HDD from the factory standard 500GB capacity to a 1TB.
