SM12). dmesg fills with hundreds of errors like "btrfs csum failed ino 93608 off 425984 csum 2316250426 private 3579463503". I had simmilar problems with the older model, Seagate Momentus XT bought two years ago, where firmware update didn't solve them (cf. http://superuser.com/questions/313447/seagate-momentus-xt-corrupting-files-linux-and-mac and http://forums.seagate.com/t5/Momentus-XT-Momentus-Momentus/Momentus-XT-corrupting-large-files-Linux/m-p/109008). Now I want to give Linux another try on this amazingly fast hardrive. Yes - the drive perfectly well under default drivers on Windows XP. I use it everyday and I never lost a single byte under Windows. What can I do on my part to help you troubleshoot the problem? I guess I might do some sort of tripwiring files to see that their contents actually degrades, but I think it the result is obvious and not very helpful to you. If you can't help me, please advise me, how to heal the partition - the offline btrfsck (from btrfs-tools 0.19 available on Mint 13) doesn't fix anything here. Is there any way to tell which files are getting broken? I use Mint 13, 3.2.0-30-generic 64-bit kernel. -- Adam Ryczkowski Skype:sisteczko
