And allegedly there are numerous cases proven to be solved by their new feature. I just wonder if algorithm against ECC enables us to gain access to user data, why insist on working with MC? Even in ACE's free support blog, there are articles about recalculating translator after backup of vital sys files

I had a case recently, no user data access, only through the utility sectors could be read, the first 180,000,000 or so showed no data whatsoever, on spin up the log showed MCMT errors, sys file 348 copies 0,1 were both damaged in exactly the same areas so a composite was not possible, even with single sector, ECC ignore.
I did gain access to the data, but it involved more work.

The optimal way is to read MC system file with error ignoring re-read bad sectors (PC3000 allows to do that). Finally you combine good part of it with bad part together and write fixed in the drive. After repower you should get full sector access.
Pls see my operation, any suggestions? thanks in advance.
