Lenovo 64 TB USB Stick will not mount after formatting.

Ok, I just checked that link and I can almost assure you that what is being presented is not accurate.

Currently, it would be rare to find any USB flash drives in excess of 8TB. With today's prices, even if a 64TB drive was available, it would be very costly to say the least. Definitely much higher than the 18 pounds listed on the eBay page.

Let's see if we can find what the actual storage capacity of this flash drive is. To do so, we need to use a few commands in the Terminal app on your Mac.

1. First, we need to identify the drive. With it connected to your Mac, enter: diskutil list external, and then, press enter.
2. Note the disk# listed in the results of that command.
3. Now type: diskutil info disk#, where disk# is what you found in the first step, and then, press enter.
4. Enter exit, and then, press enter to close the Terminal.
5. Please post back your results.

Yes, you done it correctly.

I have to be honest. I will need to digest this for a bit. I have never come across a 67 TB flash drive. The partitioning does indicate that it is formatted for exFAT as you mentioned.

My suggestion would be to erase it with the following command in the Terminal:

• diskutil eraseDisk exFAT "NewVolume" /dev/disk2, where NewVolume can be anything you want.

However, I suspect that this will still not be a solution, and my reasoning is as follows:

• As of 2025, the highest commercially available USB flash drives typically max out at 2TB (e.g., Kingston DataTraveler Max, SanDisk Ultra 2TB).
• SSDs can go much higher, but even enterprise-grade NVMe SSDs max out at around 60TB (e.g., Nimbus Data ExaDrive, which is an SSD, not a flash drive).
• A 67TB flash drive would require NAND flash memory with an extreme density that does not exist in consumer devices today.

All in all, I still think you have been led astray. I suggest that you visit the Lenovo site to see what flash drives they actually sell. If they do not sell 67 TB drives, you should return this drive and get a full refund.

A 64TB USB stick is highly unusual and likely either a fake or a drive that is incorrectly reporting its capacity. Most consumer USB sticks do not exceed a few terabytes at best. If you obtained this from an unknown or non-reputable seller, there is a high chance it is misrepresenting its storage capacity. Could you please provide us with a link to this stick so we know exactly which one you are referring to?

Did you mean to say 64GB instead?

I sort of had the same problem with a new Lenovo 2TB stick: it won't format as APFS: it gave an error: see screenshots:

Using "MacOS Extended" format did work however, and mouted; it took a very long time to do the formatting, so I don't think it's very good quality... very cheap though, €60 if I remember well... quality has its price, as is shown once again ;-) Hope this helped a tiny bit,

Yes, I have had a look at Kingston for instance. Probably best to go to their website though - anything on eBay might be a counterfeit product.

Yes, going with the manufacturer first is typically a safe bet. Next would be a reliable vendor. The last place would be places like eBay. There is a reason why they are advertised so cheaply.

P.s. I didn't really know what Cloud providers used these days. I assumed it was both tried and tested but above the performance of what I could buy at my local or online retailer.

Not necessarily. FWIW, I have been using Synology NAS's for years. My current one, a DS916+ (came out in 2016) is still going strong. It is a four-bay HDD unit that also had the option to add an external eight-drive bay. It currently is loaded with four WD 4 TB Red Plus drives. I have it configured for both file storage and for Time Machine backups.

I already mentioned a couple of 2 TB flash drive for you to consider: Kingston and SanDisk.

One thing to keep in mind. Flash drives are mainly designed for convenience, not reliability. By that I mean, you shouldn't use them for long term storage. If your work is critical to you, I suggest that you employ a Network Attached Storage (NAS) device. (Two excellent players in this field are Synology and QNAP.) These have multiple functions, not just for file storage, but come in much greater capacities. Most also use HDDs, but some newer models also support SSDs. HDDs are still much cheaper per TB, and are the "golden standard" for storage. Why do you think major Cloud storage providers have HDD-based servers for this purpose?
