Hi, it's risky to guess CHS geometry from the MBR, because partitions don't necessarily end at cylinder boundaries.
Using CHS internally means to use int13 calls to read/write sectors using CHS values (which Linux does not do). For those the only values that make sense and are safe are the ones compatible with the BIOS, irrespective of what is in the boot sector or MBR! The only reason why CHS is used at all internally for BIOSes that also support LBA is for compatibility with older device drivers (think of cache) that only know about CHS. If all is well, your pendrive's boot sector(s) use the 1021/124/62 geometry. You can always use SYS CONFIG (see docs\sys.txt) with forcelba or set the partition type(s) to an LBA type (0c/0e/0f) (which makes the drive invisible to MSDOS < 7) to avoid all the CHS complications.
