Subject: external drive size differences
Date: Sun, 15 Aug 2004 11:37:59 +0200 [thread overview]
Message-ID: <20040815093759.GK31901@lbsd.net> (raw)
Something very very interesting... below is an external drive enclosure
supporting both USB2 and Firwire, fitted with a 200Gb IDE Hdd.
When plugged into the firewire bus, i get 137Gb size, when plugged into
the usb bus, i get 200Gb size.
Could this be a bug in the kernel? or external hardware?
