Recently I’ve bought ECO 128GB USB drive and noticed it has total capacity of only 114GB unlike other flash drives and cards of 128GB I own that have 119GB since 128GB=119GiB because 128 000 000 000 bytes / 1024^3 equals 119GiB. Can I somehow unlock missing 5GB of disk space or this is false advertising by SanDisk?
Probably due to cluster alignment and/or space reserved for clusters that go bad.
A lot of clusters must go bad to take 5GB of space.
Over 5 yrs it can happen.
When you run Windows’ DiskPart what does it show for the drive?
Hard to believe…
The same issue is shown on video below, so I am not the only one lucky having SanDisk ECO with capacity reduced by 5GB.

Some space might be reserved for system files or performance purposes. You can check for unallocated space in Disk Management, but it’s normal for some space to be reserved. It’s not false advertising, just how storage is handled.
In Disk Management there is no unallocated space.
And YES it is false advertising when you advertise drive has 128 GB then you explain that during conversion from decimal to binary capacity drops to 119 GB and then you drop capacity by next 5 GB.
Some storage space is reserved for system files or performance needs. Check Disk Management for unallocated space, but a reserved amount is normal and not false advertising—just part of storage management.
Some storage space is reserved for system files or performance optimization. You can check Disk Management for any unallocated space, but it’s normal to have a portion reserved—it’s part of how storage management works, not false advertising.
