Due to this issue being brought to IRC #ubuntu I did some background research to try to confirm Danny's theory about sector-size.
So far the best resource I've found in the Promise Knowledge base (kb.promise.com) is: https://kb.promise.com/thread/how-do-i-create-an-array-larger-than-2tb- for-windows-xp-or-windows-2000-32-bit-operating-systems/ This page contains the following table: For this logical drive size Select this sector size Up to 16 TB 4096 bytes (4 KB) Up to 8 TB 2048 bytes (2 KB) Up to 4 TB 1024 bytes (1 KB) Up to 2 TB 512 bytes (512 B) The page intro says: "This application note deals with a specific application for VTrak M-Class and E-Class in a Windows 2000/WinXP 32-bit OS environment." >From fragments in other Promise KB articles I do think this is the formula the Promise Fastrak Windows drivers follow so might be a basis for a permanent and reliable fix. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/599255 Title: dmraid fails to read promise RAID sector count larger than 32-bits To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dmraid/+bug/599255/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
