【Data Erased】SanDisk 512GB + 32GB x 3 piece set

Thank you for viewing.
This set, including a large-capacity card, is being offered due to PC parts consolidation.

[Important: Product Reliability and Data Erasure]
Prior to listing, this product has undergone the following operational checks and maintenance using specialized knowledge. You can use it with confidence.
Actual Capacity Recognition Check: Using the fdisk command in a PVE Ubuntu virtual environment, we have confirmed that all cards physically recognize their advertised capacities (512GB/32GB). We guarantee these are not capacity-falsified products.
Complete Data Erasure: Using the dd command, we have completed a zero-overwrite erasure (complete wipe) by writing 0 to all sectors. Unlike a normal quick format, there is no need to worry about previous data being recovered, making it safe for privacy.
Full Area Write Test: We have confirmed that writing completes without errors to the end of the device, and there are no abnormalities such as bad sectors.
