I'm trying to figure out how to restore my USB drive to its original state because I remember it having several hidden partitions that managed data transfer. These partitions were labeled something like "security" or "buffer," but I can't find any information on them now. After using the drive as a boot device, it now shows up as a single partition, and after trying to restore it with diskpart, it fails during larger file transfers. Any tips or resources on how to get those hidden partitions back would really help!

Restoring those hidden partitions might not fix the issues you're experiencing. Can you clarify what you mean by "reasonably sized data transfer"? What file sizes are you trying to write? Also, what specific USB drive are you working with? If it's just a budget flash drive, be aware they aren't very durable and might fail if used heavily. Check what format your drive is; is it exFAT, NTFS, or FAT32? If it's an external HDD or SSD, consider using CrystalDiskInfo to check for errors.
It's worth noting that most USB drives are formatted as a single partition when you buy them. If you were seeing multiple partitions, that might have been a temporary setup created for specific use. You could be mistaken about the hidden partitions actually existing. Did you check all drives with Disk Management before making any changes?
I'm actually pretty sure I saw those partitions before. I've checked with Disk Management before I used them. It's frustrating to see these issues now.
I usually run into problems transferring files between 50MB to 2GB in size, trying to move larger files like 1-50GB. I've had issues with a Sandisk 64GB flash drive and a 1TB USB drive, which were both used as boot drives. They worked fine until I consolidated the partitions, and now they can't handle larger transfers without failing.
