i got an Xcraft HD enclosure for real cheap (you get what you pay for, oops) http://www.coolermaster.com/products/product.php?act=detail&tbcate=32&id=3219 it comes with a silly barebones manual that tells you to slide it in and screw the screw or some such, not very helpful. it also with a USB connector that has one junction fitting the device coupled to what i am calling a daisy chain of two USB connectors. i have taken pictures of all these things and put it on the web: http://www.monkeyview.net/id/965/fsck/index.vhtml there are a total of over 1000 pix, mostly dmesg, but crucial ones http://www.monkeyview.net/id/965/fsck/dmesg/PB12001901.vhtml showing my model #M6800N ASUS notebook travelstar hitachi decal http://www.monkeyview.net/id/965/fsck/jumpers/PC170027.vhtml and an album of 28 photos closeups of the guts of the enclosure http://www.monkeyview.net/id/965/fsck/jumpers/index.vhtml BIOS doesn't see the HD http://www.monkeyview.net/id/965/fsck/bioshd/index.vhtml and the first of a series of pictures documenting experiments with plugging the two USB junctions into the laptop http://www.monkeyview.net/id/965/fsck/bioshd/p1100033.vhtml it hangs differently depending on the USB connection configuration. i have been told that it is meant to draw power via the USB connections, but that the power of my laptop is insufficient to spin the drive. can anyone offer any ideas, perhaps an external power source, is it possible to buy such an accessory without spending the equivalent an entire computer, hopefully less than $30, i don't know? i was told to futz with the "jumpers" but i am not sure how to do that. TeRReF: No, no. Unscrewing will ruin the HD for sure. These settings: http://www.monkeyview.net/id/965/fsck/jumpers/PC170031.vhtml relate to the group of 4 pins you see here (the group on the left): http://www.monkeyview.net/id/965/fsck/jumpers/PC170021.vhtml As you can see on the first pic, there is a little rectangular device that is used to connect two pins so you can alter the settings. No rectangular device at all means the HD is set to master for instance. I think the current setting is the right one. If you still have that rectangular thingy, you could try the other two settings. *----------------------------------------------------------* Kayven Riese, BSCS, MS (Physiology and Biophysics) (415) 902 5513 cellular http://kayve.net Webmaster http://ChessYoga.org *----------------------------------------------------------*
