I have a Macbook Pro 2017 here, the issue is the external HDD has those stupid Micro USB Type B, USB Type A connectors. So I went and got a Micro USB Type B > USB C cable. I connected the drive formated as exFAT, the drive has power and is operational though it is not detecting the drive.

I tried terminal diskutil list and it does not show the drive>
Also in system report it shows nothing connected to the Thunderbolt ports.

Anyone have any ideas here? This is why I hardly work on macs witht their inane system specs.

Do you mean Mini USB like the pic below? If so, that drive is ancient and slow USB 2.0. I wouldn't use that drive except to save data from it. Most portable drives of that age will have issues. Why didn't you just try with a USBC-USBA adapter or hub?

What was the status before you looked at it? Did you try to plug it into another computer.

Another thing. Open terminal with out the drive plugged in. At CLI type in pwd. That tells you what directory you are working in. Then type in ls -Al /dev > dev01.txt. That is a list of all devices it sees in dev01.txt. Plug in the drive, wait 10 seconds, then type in ls -Al /dev > dev02.txt. you open them side by side to see if there is any differences. If it's being "seen" you'll see new entries in dev02.txt.
 
It is a drive that a client has

It is a WD Drive that the client purchased, it looks to me that the cable does not power the drive enough. As it does actually power on, light on etc though does not detect on windows or mac. Can someone reccomend a specific working cable or way about to do this?

I plugged it into mac no detection plugged into PC with the Mini B- USB A Cable detected.

"No such file or directory"
 
Gave up incompatible drive. so will have to grab the receipt from customer negotiate with store to see what I can do, nothing most likely. I normally purchase the drives myself though was busy and advised the client to get one and not being specific. My bad sigh.
 
I did advise the customer to tell the store that it was for mac, one of those chain stores here he went to called "The Good Guys".
The sales person stated yea fine with mac systems..hmmm. So am taking the hit and going to order a drive via my supplier very annoying though.
 
So the USB-C to USB-B cable you bought didn't work?

And it didn't work on a Mac or a PC?

The USB-C to USB-A adapter and the original cable worked?

So, the summary is that you picked up a defective USB-C to USB-B cable?

I'm curious as I usually keep a couple USB-C to USB-B cables just for this purpose and have used them on Macs and PCs and never had a problem.
 
Well in the end I purchased an adaptor for the purpose, always shy of them though this one worked fine.

USB-C TO Friggen USB-A Adaptor

I've bought quite a few of these simply because USB-C is becoming the default on most laptops and there's still an awful lot of USB-A equipment out there. Never had a single issue with them, either.


and an even better deal:


These adapters are not "rocket science."

I've been buying 5 packs of these, no adapter involved, straight USB-C to USB-B. For hard drives I like to minimize connections. They've all worked fine.
 
No has a USB MICRO B > A
OK. I have never seen a USB external hard drive that comes with that connector. This might be what happened in that store the customer went to:

CUSTOMER: I need an external hard drive for a Mac.
SALESMAN: All the external hard disc drives have USB-A connectors, so you'll need a different cable [thinking the Mac only has USB-C]. Here's the cable you need for a Mac [idiot salesman gets the wrong cable off the shelf, doesn't check the connectors].
CUSTOMER: [swaps the cable in the drive box with the one supposedly needed before handing to frase]

USB 3.0 Micro-B sockets (on all portable HDDs made in the last 15 years) will accommodate the smaller USB 2.0 Micro-B plugs for backwards compatibility. Either the Mac doesn't support USB 2.0 conveyed by that cable, or it's a charge-only cable.

Only external SSDs include a USB-C cable for use on newer Macs to my knowledge, but they are obviously more expensive drives.

In hindsight it would have been better to instruct the customer to get any portable HDD, it's only the format that might be different on Mac-specific ones. And I haven't seen any Mac-specific ones in recent years, ones that mention Mac compatibility include an NTFS driver for Macs that installs automatically.
Even better, buy 1 or 2 external drives in stock when you seem them cheap and mark them up to full price when you sell.

Why take the hit when it's the Good Guys salesman's fault?
