The hard drive on my P4 is failing fast and I am replacing it tomorrow. For the moment, I still have access to my BOINC directory. Is it possible to copy over the 2 day's worth of WUs so that the new BOINC/Seti installation sees them and will crunch them? If so, is there anything special that needs to be done (edit an xml file or whatever)? The OS is Linux.

Thanks for your insight!

My bad...wrong forum. Moving this to the Linux Q&A. Nothing to see here. Tech savvy, not forum savvy.

The hard drive on my P4 is failing fast and I am replacing it tomorrow. This unfortunately must include an OS re-installation. For the moment, I still have access to my BOINC directory. Is it possible to copy over the 2 day's worth of uncrunched WUs so that the new BOINC/Seti installation sees them and will crunch them? If so, is there anything special that needs to be done (edit an xml file or whatever)? The OS is Linux.

Thanks for your insight!

Quick answer, yes, you should be able to move them, get them off and first and then we'll worry about getting them back on the new drive.

When you're ready to power down, just copy the entire \BOINC directory and all the files contained therein. After you reinstall the OS, restore the entire \BOINC folder and re-launch BOINC. It will pick up right where it left off.

Unfortunately, Linux had crashed while I left it idle. The drive is failing fast enough that fsck rewritten inodes can't be read upon reboot so the whole thing is off, and I'm not going to try another hour-long fsck session.

Thanks for your help anyways!

That's unfortunate, but its no real loss. BOINC has a built-in mechanism for recovering from such problems. The WUs will still be listed in your account online, and there will be no way to recover them to your account, but as soon as they "expire", they will be re-sent to other computers to crunch. No real science will be lost.
