Its to do with blocksize. Try 'time dd if=1.9_file of=/usbhdd/out obs=xxxx' Vary xxxx over 2**n : 8 <= n <= 16. On my usb key ~3000 was optimum. YMMV. Unforunatly vfat(at least my version) doesn't support blocksize as an option. Brian -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
