Re: USB Flash/Jump Drives-Linux??

[Joshua Rogers <joshuarogers@hopper.net>]

I have three thumb drives: MicroAdvantage Quickdrive 64Mb, Lexar 
SecureMedia 512Mb and a 256Mb (forgot the make).

Anyway, I'm using 2.6.10.  The kernel accesses all three of them just as 
if they were normal drives (SCSI drives).

If your config is like mine, then you can just...

mount /dev/sda1 /mnt/ThumbDrive

I have this line in my fstab:

/dev/sda1 /mnt/FatDrive vfat noauto,exec,rw,user,umask=000 0 0

Linux treats it just like a normal SCSI drive.  I can't remember what 
options I enabled in the kernel.
