I don't have any 18.04 physical installations.Ĭome to think about it - Windows has a few settings that will prevent Linux from accessing disks. There's a firmware update needed, but it is only available through Windows with a USB3 port, which I don't have. VL812 Hub <- this has caused problems previously. ASM1051E SATA 6Gb/s bridge, ASM1053E SATA 6Gb/s bridge, ASM1153 SATA 3Gb/s bridge No JMicron stuff in that machine, but there are these:

Tomorrow I'll plug it into a Core i5-750 box - that's 2010 era - and see how it sees it. Picked up an new 8TB USB3 disk a few weeks ago. JMS567 SATA 6Gb/s bridge that works fine with any huge storage I've connected. I'd look for BIOS updates first for all the different hardware - motherboard, northbridge, southbridge. Suspect the GPT partition table is corrupt OR the jmicron hardware doesn't support the large disk without some specific driver that is only supported via Windows. Use gparted to create a fresh GPT partition table, then create 1 partition and format it with EXT4 as the file system. MBR/MSDOS partition tables are limited to 2G or less. The only trick I found was using current disk/usb controllers and ensuring the partition table is GPT. One of the 4TB disks was used in a 12.04 system. Have many 4TB and a few 8TB disks connected via SATA and USB to a 16.04.6 machine here. Linux has supported huge disks for longer than Windows has. It showed as an 801GB drive with all Linux partition programs and also under Windows 10 Disk Manager. I also had similar problems with a new/unused 3TB HGST SATA drive (HUA723030ALA640). Is the problem in the USB driver in reading very large disk drives? Is there a problem with Ubuntu 18.04.03 and very large disk drives? Read the disk parted would not read the disk. Showed it to be a 1.8TB, partitioning unknown (PMBR) the fdisk -l programĪlso showed it to be a 1.8TB with unknown partitions the graphical GParted I connected it to my Linux computer (specs above) and the Disks program Two data files to the drive the surface pro read the data files into (up to date as of today: 15 December 2019) and started the programĬrystalDisk to check the drive. I first plugged it into a Microsoft Surface Pro running Windows 10 I connected a Western Digital WD Blue WD40EZRZ SATA 6Gb/s Using a JMicron SATA to USB plug and power supply Motherboard: Asus M5A78L-M, chipset: AMD RS780, BIOS: AMI 1303
