Lucky me I found a bug in the A590/2091 (A590 in my case) firmware. Right now I am running diskdoctor in the hopes it can fix everything up nicly ( I *do* have a backup - thankfully!) - it just finished - but the disk still won't validate ( it did not screw up the disk though!) How it happened: Open two shells. Have a neary full disk (xt 20meg) a big file (1/2 meg). The disk was 92-94% full - cant remember shell1: shell2: run join x x as pipe:a copy pipe:a y ;this avoids disk thrashing. copy is smarter than join <request: Disk full> delete a couple small files <click retry> <request: Disk Full> Delete some more small files <clik retry> <request: Disk Full> Delete some more small files <clik retry> <request : Disk FUll> <click cancel> Then the disk churned a little bit (I Though it was removing y) then "Task Held bla bla bla " requester. Reboot -- disk won't validate, with complaints about "Key 15568 corrupt file" then "Key 15568 bad header type". Diskdoctor ran, complained about 19 bad keys (non continuous -- near the middle of the disk) and finished. Is there anything I can do before I run format/restore??
