So... when I put a drive in my USB enclosure, it shows up as a 4T drive, but when I attach it to my mfi-driver card, it shows up as 2T. Not the size that 2T drives commonly are (which is 1.8T), but 2T. (BTW... mfi is in passs-thru mode) So... how the world sees this drive: da6 at mfi0 bus 0 scbus4 target 6 lun 0 da6: <ATA ST4000DM005-2DP1 0001> Fixed Direct Access SPC-3 SCSI device da6: Serial Number ZDH1BN4H da6: 150.000MB/s transfers da6: Command Queueing enabled da6: 2097151MB (4294967294 512 byte sectors) da6: quirks=0x8<4K> but: [1:46:346]root@vr:~> camcontrol identify da6 | grep LBA48 LBA48 supported 7814037168 sectors yet is there a quirk to correct this? If camcontrol sees 4T, why doesn't it probe as 4T?
