我最近在 USB 驱动器上运行了f3write
、f3read
和f3probe
测试。驱动器的大小是合法的,但 中显示了一些损坏的扇区f3read
:
Data OK: 7.49 GB (15697680 sectors)
Data LOST: 124.00 KB (248 sectors)
Corrupted: 124.00 KB (248 sectors)
Slightly changed: 0.00 Byte (0 sectors)
Overwritten: 0.00 Byte (0 sectors)
运行f3probe
显示驱动器的正确大小:
Device geometry:
*Usable* size: 7.50 GB (15728640 blocks)
Announced size: 7.50 GB (15728640 blocks)
Module: 8.00 GB (2^33 Bytes)
Approximate cache size: 0.00 Byte (0 blocks), need-reset=no
Physical block size: 512.00 Byte (2^9 Bytes)
我认为任何坏扇区都意味着要将此驱动器退还给卖家,对吗?还是所有 USB 都有一定数量的坏扇区?
