I'm trying to understand the permanently reduced capacity after disk clone.

We cloned from a 64GB SSD to a Transcend M.2 1TB SSD (with SATA adapter) using an Addonics Disk Duplicator (I guess it does a binary copy like dd). After that the 1TB disk's capacity is reduced to 64GB. Notice that it's the CAPACITY seen by BIOS and OS, not the size of any partition, volume, or file system.

I don't see any free space after the 64GB at all, neither in Windows Disk Manager nor in Linux gparted/fdisk/lshw. All partitions are removed and partition tables recreated (GPT or MSDOS), but that did not help. Again, it's not about partitions, it's the capacity.

I have done partition extension and file system resizing before, and none has failed like this. I tried this but it didn't work.

dd if=/dev/zero of=/dev/sda bs=512 count=1

Furthermore, disk is showing a wrong number of cylinders, much less than what it should have.

Any thoughts? Should I blame the SSD or the duplicator? Thanks!

I ran hdparm:

hdparm -N -g /dev/sdd

And this is the output:

geometry = 61057/64/32
sectors - 125045424
start = 0 SG_IO: bad/missing sense data, sb[]: 70 00 0b 00 00 00 00 0a 00 .. 00 max sectors = 125045424/1(1?)
HPA setting seems invalid (buggy kernel device driver?)
