Hello,

I recently bought jmicron controllers to put away some duplication load (for mdraid level 1) from the system to those controllers. I have one jmb56x and two jmb39x attached, smart readings work well besides one thing which makes me stomachache: I need to force on one of them for a sector as its boot record is stored there.

with "hdparm --read-sector" I searched for a free one on this device and could not find one in the range of 33 <= LBA <= 62

Is there a specific reason why it is limited to this range? My partiton tables start at 2048, so there would be much sectors before which are free (and zero-filled). I tried with jmraidcon implementation, as I do not know how to e.g. mask 2047 in the command {READ_CMD, 0x00, 0x00, 0x00, 0x00, 0x21, 0x00, 0x00, 0x01, 0x00}; I just swapped 0x21 with 0xfe - LBA sector 254 which is also zero-filled on this device and it succeeds as well with this, so I assume the limited range is not caused by the JMicron controller not accepting the commands there?

I read all sectors until 2048 and from sector 105 starting they are all zero-filled (attached the txt of the affected drive). I would prefer to avoid always overwriting and restoring parts of my bootrecord, but as I am not sure why the limit is currently implemented this way, I would like to clarify this first. :-)

Thank you so much!

Best regards Alois

I have got a SAMSUNG SV1604N with firmware version TR100-23. After some research on the web I found out that I need to manually append -v 9,halfminutes -F samsung2 in order to get a correct output from smartctl. -v 9,halfminutes is needed otherwise Power on Hours is insanely high (~750000 hours) -F samsung2 is needed - otherwise I get an extra warning: "Warning: ATA error count xxx inconsistent with error log pointer 5" Please add this information to your drive db so that everybody will get the correct values by default. Thanks
