USB not showing up since today

I have an SanDisk USB (Gen 3 I think), now I am using the Apple to USB A Camera Adapter. I have been using it, but didn’t transfer any files. It was NTFS. It shows the USB. Now it doesn’t even show it. It just says “The attached accessory requires too much power”. I re-formatted in FAT32 and exFAT and even UDF, the issues still exists. It doesn’t even appear in NTFS again. I tried different angles but no. For anyone wondering, yes it has 2 partitions since I have a Ventoy USB (a software that can have more than 1 multiple ISO for Windows, Linux, etc on USB and it requires you to have 2 paritions (1 for storing ISOs and 1 for firmware) and it can basically support copying / viewing any file)

iPad, iPadOS 17

As the iPad has limited power capabilities, dependent upon the Storage Device, an external power source is often required. For HDD or SSD, connected via USB, an external power source is almost certainly required.


If your iPad has a Lightning port, you will require an Apple Lightning to USB 3 Camera Adapter - this Adapter having both a USB3 Type-A port to connect USB accessories or storage, and a Lightning connector to which you must connect your Power Adapter:

If you have one of the newer iPad Pro models, with a USB-C connector, you may need to utilise a powered USB hub (i.e., it has its own source of power) - connecting both the iPad Pro and the storage device to ports on the hub.

To be recognised by iPadOS, the attached USB storage device must be formatted to FAT, FAT32, exFAT, APFS or HFS+ with a single partition. Microsoft NTFS is not supported by iPadOS.

Bro it was appearing when I first formatted it in exFAT, after plugging it back in (my charging went low so I came back after a time) after that it just prompted “The attached accessory requires too much power.” It showed NTFS too and it doesn’t now, both FAT32 and exFAT worked but after re-trying, re-formatting, even just transferred a few files. I even did a fresh format from Windows and not Ventoy, this time it didn’t have 2 partitions but still didn’t appear in the 4 formats (exFAT, FAT32, NTFS, UDF) With all partition style MBR and GPT, it simple doesn’t work
