I have a toshiba ext hard drive. I have data on it and I've never had a problem. Yesterday I moved my computer from one room to another. When I plugged the ext. back in, it doesn't show up on the desktop or in disc utility. My other two ext. drives show up like normal. The data shows up on my husbands and sons PCs but not on my mac... my husband formatted it to exFat but it still won't show up on my Mac... any suggestions on how to fix this?
I have tried different USB ports. The cable is not a standard USB on one end and a smaller version on the other. It has a USB on one end and a long thin connector to the hard drive. There is no external power adapter. It only has the USB cable. I can feel the disk running when it is plugged into my Mac. The indicator light is on too.
I never used the Boot Camp set. I'm fairly new to Mac. Before this iMac i had a Mac Mini. I didn't use the migration assistant either because I didn't have anything to migrate.
When I moved the system I shut it down then unplugged everything. If I'm removing something (thumb drive or even iPod) I always eject first. This time since I had shut down the system I didn't eject the drives first.
I believe it was Fat32 initially. ExFat was done after the mac failed to show the drive. After I tried a few times (switching USB ports and such) we decided to try to format it to exfat (since hubby's pc doesn't to FAT32) and see if that would work. I'm beginning to think a new drive would be less painful.
Well, the good news is that your OS X version meets the minimum requirement to access exFAT drives (minimum of 10.6.5).
As the drive was formatted recently, I assume there is nothing on it. Is that correct?
If so, I would suggest going to a Windows box simply removing all partitions (pretty much wipe the drive) and then trying again with the Mac.
Honestly, I am baffled by the Mac not detecting the drive being connected at all, but it is readable/useable by the other PCs. Especially since you said this happenss on all USB ports.
BTW, do you have a powered USB hub attached to your Mac? If so, try connecting the drive to it. Just as a thought, you aren't plugging the HDD into the USB ports on your keyboard are you? If so, plug directly into the Mac.
A powered USB hub is used to provide additional USB ports to systems. You can add 4-8 additional ports while only using one USB port on your computer. A powered HUB has its own power supply to provide power to devices.
How many other USB devices are connected to your Mac? Have you tried with only the minimum stuff (keyboard, mouse, dreaded HDD in question) attached?
Sorry it took me so long to reply... groceries... I don't know why people here think I should feed them. Sheesh.
There are a total of three small externals (including the difficult one) and the occasional iPod or nook or thumb drive plugged in. The externals are always plugged in but the other stuff only gets plugged in when I need to add stuff to them.
I did try just plugging in this toshiba only, unplugging all other devices. That didn't do it either. My husband said something about formatting this Toshiba in FAT32. I think he found a way to do it on his PC. We'll give that a try to see what we come up with.
