Re: [PLUG] Desktop Support ?

Do you have another computer from which you can make a knoppix USB KEY or CD? It does really sound like an HD issue to me, but a badblocks scan is probably a good idea.  The good news is if you have a spinning hard disk in there,  SSDs are really cheap and will give you improved performance and battery life.

thanks for all of your help everyone !  here's an update with more info:

re: the Dell connectivity.  i followed anthony's instructions and deleted ALL of the existing info for wi-fi networks.  then i created a new one and re-entered all of the info.  i restarted it but got the same frustrating result.

re: the eeepc- i restarted it and let it run thru the disk check and got this message: "the drive for /temp is not ready yet or not present"

i pressed "m" for manual recovery and it ran some sort of system check that lasted for several moments but finally froze up.  this was the last line " buffer I/O error on device sda1 logical block 29373405"

thanks once again !

Is there any kind of study on this?  That is certainly not my
expectation for a hard drive, and (not being an EE) I'd think that you
could design a circuit that stopped writing when the voltage supply
dropped.  The drive already has the ability to retract the heads after
a power failure, so it has some kind of capacitor/etc for such things.
If the drive is retracting the heads on a power failure that would
also preclude it from writing anything while those heads aren't over
the drive.

It sounds like somebody just needs to boot a rescue disk and fsck the
filesystem and see what is going on.  If it looks serious I'd probably
clone the drive before attempting repairs.
