I have some kind of 8 Gb Feiya Technology Corp. Flash Drive
, which is stopped working - it is seen by the system, but I can not write any info there. I tried to use some of Transcend recovery tool and in result now it is seen as 16 Gb Transcend drive. My primary system is OSX, but I can use Windows also to test/repair it.
The first question is how to restore it is correct size? Looks like I can use TestDisk to change drive geometry, but what should be correct number of cylinders, heads, sectors and sector size? Now it shows
Disk /dev/rdisk1 - 15 GB / 14 GiB - 31108608 sectors, sector size=512
