What else can I do? maybe ask kernel devs if there is a way to access the drive even with a capacity of 0 to copy everything from it before you stuff it in the garbage can?

Well total space taken by bad blocks according to chkdsk is less than 1MB, 1 block = 512byte. So you have ca 2000 bad blocks. That is A LOT. windows is still able to access all data. Linux is only able to see partition table for a while - as you can see in dmesg. If firmware is broken then how it is possible that windows is able to use this disk? maybe they ignore things like a reported size of 0 and no sense. Well.. I've backed up data from it already. then throw it away. That disk will fail completely soon.

If I had a spare drive from the same batch, I'd swap in the not-dying controller card and see if that got me anywhere. Since the drive's already backed up, though... that one's a new paperweight for the desk, and if the data's anything sensitive, physical destruction of the drive's the way I'd go to 'secure' it before it goes out with the trash. -- Poison [BLX] Joshua M.
