I recently reinstalled Windows on my PC because it was running really slow, and now my 2TB SSD is only showing 1.8TB of storage. I'm currently using Windows 11 on a Samsung SSD, and I even noticed a random 100MB disk appearing. What could be causing this discrepancy in storage?

Yeah, it can seem misleading. Windows is just presenting the size in binary, which is why you're seeing that lower number. Your SSD is showing the correct amount based on the binary measurement. It’s not actually an error or loss of space.
Honestly, don’t blame Windows too much! Most of the confusion just comes from how storage sizes are marketed versus how they’re actually calculated. The random 100MB disk you see might be a recovery partition or something similar. It’s pretty common!
There’s a common reason for this! When manufacturers advertise storage, they use decimal counts (where 1TB = 1000GB), while Windows measures in binary (where 1TiB = 1024GiB). So essentially, a 2TB drive will usually show up as about 1.81TiB in Windows, which can be confusing.
