	Two days ago, I shut my ubuntu system down for minor maintenance (cleaning filters) When I rebooted, I got an error message that grub could not find my drive to boot it. I pulled out that drive, and reinstalled 10.10 amd-64 on another drive. Today, as a trial to see what would happen, I re-installed the messed up drive and ran update-grub. Found the drive, rebooted, and got access. I have a bunch of seti and einstein wu's on the drive I reinstalled. Is there any to transfer them to the newly installed version of 10.10 as I really do not trust the drive I replaced? robby-8550 ____________

	It should be as easy as moving the data folder over to the proper place on the new drive. You might have to check permissions as well. ____________

	Note that if you are currently running SETI on the new OS, you cannot simply merge the two BOINC data folders.

	Note that if you are currently running SETI on the new OS, you cannot simply merge the two BOINC data folders. I have done nothing re SETI on the new drive. OS is the same. I will try to do a locate on the original drive to find the data files. Question is, if I find them, should I install BOINC, then transfer the data files, or do the transfer first. I would hate to loose the WU's, as some have a due date of 3-17-2011, and some on 3-22-2011. These that have these close dates are all Einstein WU's, all of my SETI WU's are in April.

	Question is, if I find them, should I install BOINC, then transfer the data files, or do the transfer first. Search for client_state* and transfer the complete directory tree first, then install; but you should check the permissions nevertheless, as arkayn suggested. Gruß, Gundolf

	Move the files over, then install BOINC and make sure that it points to the data folder while installing. ____________
