I'm having issues with My mobile Seagate 5TB external HDD. I used it on My Xbox for a while before upgrading, now I want to connect to My router but for some reason there was multiple partitions. I formatted the hdd but now there is 3 unallocated partitions, what did I do wrong? 1 of them doesn't give Me the option to make it into a "new simple volume" and when I try to with the other 2 unallocated volumes on the hdd, it gives Me an error about not having enough space. What? It's the only HDD that gives Me problems with My router (ASUS AC66U) and I've even tried reformatting on the router itself. When doing a health scan on My router, it also gives Me an error about not being able to allocate memory. What do I do? I want it to have 1 formatted volume but I'm running into problems with allocation, I really hope I don't have to pay for some program to get it back to normal. Thanks in advance for any help.
