OK, the new 80 GB Travelstar is installed and fully functional. Before attempting the upgrade I bought a USB enclosure for it, then attached it to a USB port to clone the existing 60 GB drive to it. I waited until a local LUG had a Linux Clinic (today) to perform this operation, as I was unsure of the best way to do the cloning. When I arrived at the Clinic I had not even partitioned or formatted the new drive, so that was the first step. With some assistance I created a swap and a regular partition to mirror what I had on the original 60 GB drive. I left the remaining 20 GB unpartitioned to use sometime in the future for a new installation. (Maybe 64-bitDapper, since I now have 64-bit Breezy.) Then we attempted to do the cloning. That didn't go as well. First we tried Dump, attempting to do a restore at the same time as a dump, in order to mirror the existing drive on the new drive. Unfortunately, Dump had fits when it got to my chroot environment. We couldn't easily get past the problem, so we gave up. Instead we booted to a live CD and just used cp -a to copy everything onto the new drive. Then we manually edited Grub. I swapped the disks (way easy -- just a few screws!) and rebooted. Grub messed up at first, but we got it booted with Safe Mode. Once we had it booted we fixed Grub. And then I rebooted a few times to make sure everything was working properly. I am happy to report that everything is functioning perfectly now, exactly as before. Exactly as before, that is, except that the computer is much faster. Note my hdparm scores on the old drive listed above. Here is what I get now: [EMAIL PROTECTED]:~$ sudo hdparm -t /dev/hda /dev/hda: Timing buffered disk reads: 134 MB in 3.05 seconds = 44.00 MB/sec Wow! Nearly twice as fast! And it feels like it too. The computer boots way faster than before. Everything seems to work much faster. Loading an existing OO.o Writer document is almost instantaneous. Well worth the $139 I paid for the 80 GB Travelstar! Plus I now have a leftover 60 GB 4200 rpm drive to use for something. _______________________________________________ LinuxR3000 mailing list [email protected] http://lists.pcxperience.com/cgi-bin/mailman/listinfo/linuxr3000 Wiki at http://prinsig.se/weekee/
