Initially, Seagate expressed skepticism about the reports.
Nice, so they're shipping enormous quantities of HDDs, yet can afford to take risks with their customers data by being skeptical. Why not just stop that distribution channel immediately until any doubt had been removed?
(CAUTION: unnecessary OS fanboy troll-bait ahead)
Windows/Linux/Mac, who gives a shit, variety is the spice of life, it's about what gets the work done. Weaknesses in operating systems have a correlation with the number of users using them. If there aren't anywhere near as many vulnerablilites on LInux/Mac compared to Windows, it's because no criminals have spent the time looking for them as they don't pay very well, yet. (yes, I know the communities of both spend a lot of time looking for vulnerabilities (as does the Windows community) and the fact that the code is open to peer review is contributory towards their having the potential to be more secure, but given a large enough userbase as to make it profitable to write virii for these systems, are you going to tell me that some enterprising criminals are not capable of writing exploits for these systems too?). In other words, if the entire population used Linux, would virii dissappear? I think not.
Just be careful, whatever platform you entrust your 1's and 0's to!
