I have a customer who broke their MyBookWorld NAS by knocking it off a shelf. WD won't cover it because of the accident, so I install a new drive, but nothing works on it without the NAS OS. I found the OS on the WD website, but none of my guys run Linux. (Its Linux based) Do any of you use MyBookWorld out there that can make an image of the drive minus the files of corse that you have backuped up?? The OS is the same for the 500, 750 or 1Gig drives. WD will only sell a new drive which is about 3/4 what my customer paid for the NAS drive. Thanks.
