The data bank is extremely reliable. i have several ixpresses and never had problems. The only thing that happened once was the flatcable coming loose from the disk. This was after extreme vibrations.
The HD can always be replaced by Hasselblad as it has special software on it.
How extremely reliable? such as hours of operation, like the number of expsure specified for the high-end DSLR.
I doubt any extremely reliable hard disk in this world. The hard disk in the notebook computer is often the 1st thing to go, and it's not uncommon just within 3 years of operation.
But that's OK as long as the hard disk is easily replacible.
Now, other than replaced by Hasselblad, is there a way to down load that special software (paid of unpaid), then replace it DIY?
If not, what's the cost for Hasselblad to replace it? Would that be cheaper than buying a used complete Ixpress?
Any alternative other than replace the databank? I'm thinking to tether to a 8.9"/2lbs notebook computer (the $349 Atom CPU based notebook from Acer or Lenovo), if the battery can last long enough. Any known problem with this?
