Hi,
i can't add new devices! In my log i can see the error messages:
12/14 10:59:47.243 1034 SPTI: '\\.\PhysicalDrive0': The adapter supports maximum transfer length 61440 bytes less than minimal allowed (MinBufSize = 65536 bytes)!
12/14 10:59:47.243 1034 SPTI: '\\.\PhysicalDrive1': The adapter supports maximum transfer length 61440 bytes less than minimal allowed (MinBufSize = 65536 bytes)!
12/14 10:59:47.243 1034 SPTI: '\\.\Tape0': The adapter supports maximum transfer length 61440 bytes less than minimal allowed (MinBufSize = 65536 bytes)!
The devices in RAID5 is connected to a SCSI controller Serveraid6i on IBM X226
Thanks

1) DO NOT SHARE HARD DISKS IN SPTI MODE.
2) Check your adapter drivers and increase buffer size. At least to the 256KB. <64KB transfer size is performance killer.
