I/O error while backing up
Hello!
I'm trying to back up my MacBook hard drive to an external drive via SuperDuper! but it fails to copy everytime, saying it's unable to copy a certain file (which is different every time). I searched this support forum for a solution and decided do "zero" the external hard drive, without success. I asked help in another Mac forum and I realised my partition scheme wasn't "GUID_partition_scheme" so I fixed that and tried again... and I'm still unable to complete a backup. So I'm back here, aking directly for help this time Is there a way to know if it's a hardware problem? Me external hard drive is a 250 GB Seagate in a NexStar3 USB/FW enclosure. I used the Firewire interface to backup. Thanks! Luc |

Hi, Luc. If the file is different every time, it's likely that you're having interface issues (hardware). You can see what device is causing problems by looking at the system.log -- it'll indicate an I/O error with a device ID (something like "disk2s1") that you can then match with disks listed with either Disk Utility or System Profiler.
My guess is that it's the NexStar3 controller. I'd try the USB interface to see if that behaves better...

USB interface tried, and made its proofs.
I backed up all my MacBook drive without any problem. So, doctor, what is your diagnosis? I'll try to backup again with FW, and post my log here if you need it. Thanks! Luc Last edited by Zed; 08-22-2006 at 10:48 PM. |

My diagnosis is that it's likely that this is a non-Oxford based drive, and isn't fully compatible with OS X on its Firewire end...

Here is how it goes :

I was sure It'd be ok this time... backup was almost finished. Does the diagnosis still stands? |

Was this with FireWire? If so, yes, diagnosis still stands.

Yes, it was with FireWire.
I'll call the shop where I bought the HD and the enclosure to see what they can do for me. They sell Macs and were aware of my needs before selling that stuff to me. Thanks for your precious help. Luc |

My pleasure, Luc. Make sure to get an enclosure that has a true Oxford chipset in it...

Searched a little for the oxford thing in the system profiler and found nothing.
But I found that (yes, my OS is in french): Bus FireWire : Vitesse maximum : Jusqu’à 400 Mb/s ST3250820A : Fabricant : Initio Modèle : 0x540 GUID : 0x101005007777D2 Vitesse maximum : Jusqu’à 400 Mb/s Vitesse de connexion : Jusqu’à 400 Mb/s Sous-unités : ST3250820A Unit : Version du logiciel de l’unité : 0x10483 Identifiant de l’unité : 0x609E Révision du programme interne : 0x223 Niveau de révision du produit : 2.23 Sous-unités : ST3250820A SBP-LUN : Capacité : 232.89 Go Support amovible : Oui Nom BSD : disk1 Gestionnaires OS9 : Non État S.M.A.R.T. : Non géré Volumes : Backup MacBook A : Capacité : 74.88 Go Disponible : 49.42 Go Inscriptible : Oui Système de fichiers : Journaled HFS+ Nom BSD : disk1s2 Point de montage : /Volumes/Backup MacBook A Backup MacBook B : Capacité : 74.88 Go Disponible : 51.78 Go Inscriptible : Oui Système de fichiers : Journaled HFS+ Nom BSD : disk1s3 Point de montage : /Volumes/Backup MacBook B Autre : Capacité : 82.57 Go Disponible : 82.52 Go Inscriptible : Oui Système de fichiers : Journaled HFS+ Nom BSD : disk1s4 Point de montage : /Volumes/Autre I guess that I should have found something like "OXFORD IDE Device 1:" instead of "ST3250820A Unit :" if it was an Oxford drive... So I guess the extra I paid for the FireWire interface is now worth nothing :/ |

Actually, here's where it says who did it:
Fabricant : Initio So, it's an Initio chipset, not Oxford...
