I have an external SSD I back my MacBook photos up to and today my iPad quit recognizing it and when I plug it into my Mac the screen flashes hot pink, the track pad stops responding and the Mac restarts, any ideas?

It is possible the ssd or the enclosure’s controller has died. Do you have a Windows or Linux (best option for this kind of diagnosis) computer handy to test? I think the Mac is experiencing a kernel panic.

An electrical short is also a possibility. I’d take it apart and test the ssd in another enclosure.

I have a windows machine at work, it makes a noise when I plug the hard drive in but it doesn’t show up in file explorer. Maybe the format of the drive?

Does its USB device show up in the Hardware Device control panel?
My sense is that, given the behavior, the drive controller is gone. I have never seen a corrupted drive create the behavior you noted for iPad and Mac.

I have never seen a Mac respond with a pink screen/restart when plugging in any kind of drive, since 1987.

Not saying it can't happen.

Is this repeatable?
Does it happen EVERY time?

If so, there might be an internal short or failure in the drive.

It shouldn't make ANY noise if it's an SSD.....🤔
Or do you mean the OS pings?

On Windows, it's normal for the OS to chime when it connects to a USB device. if the SSD is formatted with an Apple format Windows can't mount the drive partition even though it connected to the hardware successfully.

I suggest then you connect the SSD to a Windows machine and if it chimes then launch Disk Management (right-click on the Start icon on the toolbar and select it from the menu). If Disk Management pops up a windows saying you need to initialize the drive that indicates that the hardware connected successfully. If you initialize the SSD at that point it will wipe all the data. If you do, you can then use Disk Management to reformat the drive to exFAT and test it on a Mac again.

Yes, every time.

OP:

Does the drive have a detachable USB cable?
If so, have you tried changing the cable?

Does the drive work/not work on any OTHER Mac?

This worked and I was able to copy my data to the drive. Weird.

Might still be worthwhile to run diagnostics. I’d use smartmontools on mac through homebrew but if OP is not a terminal friendly user then some sort of gui SMART tool can be used.

Forgot to say thanks for the suggestion.

Any suggestion on a GUI diagnostic tool?
