The hard drive in my laptop has crashed with a whack of WU's still in the cache. I'll do some diagnostics on the drive tomorrow an another system but it isn't looking good.

If the laptop needs a new drive it will be out of action for about 4-5 days. My concern is primarily for all the wingmen waiting for WU's that, probably, won't be coming in until they get re-issued near the end of April.

Sorry guys & gals...but poop happens... :-((

If you are able to get this Laptop working but it requires a new drive, make sure the laptop has the same name then install boinc, attach to seti and then detach again. this should save the wingmen the waiting

I think if that works at all, simply attaching to S@H should be enough. The Scheduler code would see that as a reattach if it figures out it's the same host, and that's when it marks all old work "Client detached".

A detach has already been done by losing the disk. BOINC doesn't report a detach to the project, it simply wipes out the project folder and removes all other project-related info from client_state.xml, etc.

I believe a detach IS reported to the project. It's a RESET that doesn't phone home.

In order to attempt to minimise power consumption, I've been running boinc from flash drives for a while now. This (in theory) allows the pc to put the hard disks to sleep when I'm not doing anything other than boinc. In practice I think Windows seems to keep finding things to do so I don't think it really sleeps much anyhow. So why is this relevant you ask? I (sometimes) have a boot script copy the boinc data directory from the flash drive as a backup. While the longevity of flash drives is debatable, the only failure I've had was on a 128MB no name cheapie after 2-3 years that deserved to be replaced due to it's diminishing size.

I have installed boinc on my laptop - running from the regular disk, but the only time I've left it running for long (unintentionally) was during a recent record heatwave & the hard disk has not been the same since. Unfortunately it's not failing badly enough to be replaceable or working well enough to be usable.

Neither communicates. Sometime last year David Anderson did write that Reset probably ought to communicate since it should effectively do the same as a detach/reattach, but he hasn't implemented any change.

Note that one expected use for detach is to get rid of a project which has died and therefor no longer has any servers. Another is for a user to simply quit doing a project they have become annoyed with, imagine the reaction if the detach phoned home.

Similar situation here.

I have a failing drive on my new cruncher. I am going to try and ghost the drive tonight but think it might be toast. The drive still boots into Win Vista Bus 64bit but everytme I try to do something a little message pops up saying that the action cannot be performed because the contents are corrupt or something to that effect. I was able to copy the BOINC directory to a network drive.

If I:
1: Install a new drive and same OS with same PC name
2: Install Boinc and attach to seti again
3. Shut down BOINC and copy the old directory in its entirety back
4. Restart BOINC

Will this box magically start crunching again as if nothing changed?

Any suggestions are appreciated. Oh and if this type of question has been posted before, please post a link.

Thanks people.

You should not need to attach to SETI at all, just shut down BOINC completely, move over your old folder and replace the installed one, I would restart just to make certain and then fire up BOINC.

It should pick right up where you left off.
