Problem with external hard drive disconnects & trackpad
Hello,
I recently bought a new MacBook Air Apple M1 Chip computer and a SanDisk Extreme Pro 1TB SSD external hard drive, which I'd like to use to store my photo library externally, as well as some other files.
At first, both seemed to work just fine. But with repeated use, I've run into two very irritating problems.
- The SSD drive disconnects randomly, for reasons that aren't clear to me. At first I thought the USB-C cable SanDisk had provided was faulty so I replaced it with an Anker one, but the problem has persisted. Sometimes it disconnects after a couple minutes, sometimes much longer. At first I thought it was happening when I accidentally nudged the cable or SSD, but sometimes it happens when I'm nowhere near the computer. Sometimes it happens when the drive isn't doing anything, sometimes it happens when the Photo library is open or I'm copying over files.
- My Macbook's trackpad also behaves erratically at times - it won't stop working, but it will suddenly become sluggish; and the multi-finger gestures (scrolling, showing all windows, etc.) stop functioning.
The thing is that the two problems seem connected. Often - not always - the SSD disconnect and the trackpad issues appear at the same time, although I can't tell which one might be triggering the other.
I brought the MacBook into an Apple Store, where they ran a full set of tests and rebooted, but found no hardware issues. I'm starting to think the SSD itself has a problem (maybe with the USB-C port?), even though I ran First Aid on it several times and found nothing, it also seems to work fine, without disconnects, on other computers.
Has anyone else run into similar issues and have any advice? Is it even possible for an SSD (that doesn't have an external power source) to somehow interfere with the trackpad, or am I just reading into the two problems too much? I'm thinking of returning the SSD to SanDisk, but wanted to ask around first to see if I'm missing something.
Thank you very much in advance !
