iphone 15 pro max 512GB does not recognize my external SSD by Seagate Firecuda 2TB. The drive has a usb C connector. It works fine with the ipad mini and my macbook air. The disk is formated to Exfat using mac os 14.0.
iPhone 15 Pro Max
I’m having the same issue with Sandisk extreme Pro 2tb.
I fought with this for weeks on my iPhone 16 Pro. I even went and bought a fancy new USB-C cable from the Apple store (which didn't help) because none of my existing USB-C and thunderbolt cables were allowing my Sandisk Extreme Pro 4TB to work. Sometimes the drive would be available, but at USB2 speeds. Most times it just wouldn't show up at all.
Someone else early in this thread had the answer, though. The iPhone USB-C port doesn't provide enough wattage to reliably power many external storage devices. Connecting the storage through a powered USB3 hub fixed all my problems. Now the external storage shows up all the time, and runs lightning fast. Any of my thunderbolt or USB 3.2 wires work just fine. I can record ProRes 4k120 for over an hour with zero problems.
Hi yoosuf86,
what cable are you using ?
I’ve tried three different cables, thunderbolt 4 but they don’t work.
thank you.
regards
Thank you for your reply. I have ordered a USB4/240W/8k/13cm cable, and it will be shipped next week. I hope it will work well with my many 2TB SSDs on my iPhone Pro Max 15. Thank you anyway.
Hello yoosuf86, I tested my new 240W/8K/USB4 cable with Gen3 4TB and 2TB SSDs. Unfortunately, it is not working correctly. May I ask which SSD and cable you are using? Thank you.
i too am having the same issue, i have tried multiple cables and refuse to buy anymore, they are all having the same issues.

Hi yoosuf86,
Unfortunately, no chance to find this cable in Europe.
Actually, I have always the same issue with all the cable ordered.
Iam done with it …
Hi Enalife.
yes I understand. And again you cannot completely rely on my experience, as we all know a software update can screw up things.
Thank you! I will check it.
Is your SSD partitioned?
But what about when the Iphone 15 pro max doesn't detect the Sandisk SSD 1 T HD or appears, it doesn't ask for a password even with accessories enabled???
This is the same for me the phone will not recognise the external drive it is greyed out and I can’t chose it when wanting to transfer
I’m having the same issue with a WD Black SN850. From a bit of research it appears to be a problem with gen4 pcie devices. Hopefully they fix this.
The drive never shows on iPhone to select it to enter password
After having the same exact issues as OP and the many others on here, I tried Apple brand USB-C to USB Adapter. ($19.99 USD) FIXED SOLVED Hope this helps.
