I Have 3bon-s35s SATA to USB converter(or controller). It use JMicron JM20339 chipset.
Windows 7 can recognize WD 4TB HDD, but Ubuntu dosen't. dmesg shows below
[ 2.990457] scsi 6:0:0:0: Direct-Access WDC WD40EZRX-00SPEB0 PQ: 0 ANSI: 2 CCS

Under ubuntu, it just reports 1.63TiB. Datasheet says it supports LBA48 (not official. JMicron site has just JM20337)

Anyway when I attached WD 4TB HDD on M/B SATA port, kernel says 4TB

It seems like that ubuntu kernel has buggy JMicron USB driver. How can I fix the problem?

partederror you report. (The backup partition table is stored at the end of the disk, so it will seem to be corrupt if the OS can't read the end of the disk.) Filesystems, including NTFS, are stored within partitions, so problems related to NTFS cannot affect partition tables, which define partitions.
