Hi members,

I was advised to post to this list to see if I could get any answers to a consistent problem I have. I had a 200 GB external drive mounted in an M9 case which I was using as a boot drive for my Mac mini G4. The casing power failed while I was using it and the 200 GB drive went from 189 GB formatted down to 129 GB and is unbootable. I bought a new 250 GB LaCie external as a new boot drive and re-installed the OS and copied as much files, docs, mp3s, pics etc that I could retrieve from the old drive. Now the computer crashes 3-4 times a day even unattended. The panic is as follows:

panic(cpu 0 caller 0x000E3DDC): vnode_writedone: numoutput < 0

Without studying the info provided too deeply: Does it only panic when the 200 GB drive is mounted? I'd guess that the HFS+ (I assume) metadata structures are corrupted on your 200 GB drive - umount and run fsck (Darwin method) or Disk Utility (Mac OS X) over the filesystem. Either that, or there's unrelocatable bad blocks in the HFS+ metadata structures that's causing problems. I haven't checked the source - what does Darwin do on metadata write failures? Panic? Second look at the panic string and backtrace, I'm guessing the later. -- Paul Ripke Unix/OpenVMS/TSM/DBA I love deadlines. I like the whooshing sound they make as they fly by. -- Douglas Adams _______________________________________________ Do not post admin requests to the list. They will be ignored.
