Recovering a file in Time Machine gives error -36 : How to debug?

"Error Code -36 means an I/O error occurred. It could either be an issue with either hard drive or simply that an error is occurring along your chain. I'd suggest trying to connect one of the drives to another bus (eg. via USB, FW400 is on the same bus) or connecting to the Time Machine HD and then to the MultiMediaHD to see if that changes anything.

Personally the only times I've seen -36 errors with Time Machine were when the external hard drive was starting to exhibit issues before dying. If you are able to run a program such as DiskWarrior to check the health of the drive I highly recommend it."

"I ran the Disk Utility analyzer without any error.
The disk is configured in RAID and I didn't got any issue...
I also replace all the cables and got the same error.

Disk Utility does not check the disk as throughly as DiskWarrior (Preferred) or TechTool Pro.

Tech Tool Pro will check the structures, as well as the underlying media, attempt recovery of bad sectors, and more.... Basically a high powered hardware test.

Disk Warrior can also do data recovery & repair, but starts with building a complete replacement directory, from the data recovered from the original data....

Disk Utility just does basic structure testing, and basic repair.. Disk Warrior and Tech Tool Pro will be significantly more sensitive to issues and assist in repairing the disk."
