--- Comment #4 from Damjan Jovanovic <[email protected]> --- newfs_msdos: 65503 clusters too few clusters for FAT32, need 65525 ---snip--- 593 if (cls < mincls(fat)) { 594 warnx("%u clusters too few clusters for FAT%u, need %u", cls, fat, 595 mincls(fat)); 596 goto done; 597 } ---snip--- so cls=65503, fat=32, mincls(fat)=65525. ---snip--- 71 #define MINCLS12 1U /* minimum FAT12 clusters */ 72 #define MINCLS16 0xff5U /* minimum FAT16 clusters */ 73 #define MINCLS32 0xfff5U /* minimum FAT32 clusters */ 74 #define MAXCLS12 0xff4U /* maximum FAT12 clusters */ 75 #define MAXCLS16 0xfff4U /* maximum FAT16 clusters */ 76 #define MAXCLS32 0xffffff4U /* maximum FAT32 clusters */ 77 78 #define mincls(fat) ((fat) == 12 ? MINCLS12 : \ 79 (fat) == 16 ? MINCLS16 : \ 80 MINCLS32) ---snip--- Note how these form consecutive non-overlapping ranges: 0x1 - 0xff4|0xff5 - 0xfff4|0xfff5 - 0xffffff4 FAT12 | FAT16 | FAT32 So the wrong kind of FAT was chosen for that number of clusters, it should have used FAT16, and when FAT16 is manually forced, it works. -- You are receiving this mail because: You are the assignee for the bug.
