Marketplace '2 TB' stick
The capacity test proves the stick really holds 29 GB within minutes, with a report that wins the refund.

USB Lab
Counterfeit detection, surface scan, benchmark, verified secure erase and formatting for USB and SD media.
The problem
Rufus checks bad blocks but has no map and no counterfeit sizing. H2testw is slow, single-threaded and from 2008. Windows refuses FAT32 above 32 GB.
Features
- Capacity test that recognises dropped-write and address-wrap controllers
- Read-only surface scan narrowed to 64 KiB with latency statistics
- Live GPU block map, p50/p99 benchmark
- FAT32 of any size by our own verified formatter
- Partition table snapshot before every destructive action
Who it is for
Photographer
Camera cards before a wedding
Surface-scans every SD card the night before and retires the one with slow regions.
Maker
Car stereo and 3D printer media
Formats a 128 GB card as FAT32 because the device refuses exFAT and Windows refuses to format it.
Benefits
- Never trust a fake 1 TB stick again
- Know a card is failing before it loses the photos
- Format for any device, including FAT32 at 256 GB
Built to be trusted
- Windows disk never listed
- Drive letter must be typed for destructive actions
- Device loss detected and reported, keep-awake while running
Good to know
Shipped. SD card speed-class detection reads the CSD register only through readers that pass it through.
