One of my IBM 60Gb Hd broke down setup in a mirror (RAID1). I cound not find a sutable 60Gb Hd so I bought a 80Gb. I know that I will one be able to use 60Gb. During the restore i was asked: Do you whant off-line copy? I said yes. The Hd started to copy, but it takes ages. 47% done after 19hours!! QA: What is Off-line copy Best Regards/Gameboy

If I'm not mistaken, the disk's are synchronizing and all the data off your 60 is being duplicated (copied) to the 80 to rebuild the RAID set. The more data you have, the longer synchronization takes. I recently setup a server with dual RAID 1's. The one set (for the OS) using 36 GB drives and the other (for data) using 73 GB drives and even with completely blank drives, the synchronization took around 4 hr's to complete on the 73's and slightly over 2 for the 36's.

Hi just had the same thing happen to me - drives were both 73 gig and they are hot swap. Took the bad one out and put the good one in and 24 hours later it was finished synchronizing and this is on the latest IBM rack mounted server with all the bells and whistles. And we were only using a fraction of the hard disk space. That is just how long it takes. What would slow it down is if you were trying to use the computer during this time period. Ours was a heavily used SQL server so that likely slowed down the synchronization process.

Thanks !! Yes it seems to be the case because I made a manual set-up and I´m copying from the 60 to the 80. I could not just imagine it would take so long. Best Regards/Gameboy
