Buffalo TeraStation PRO Rackmount TS-RIGL/R5 iSCSI - Harddrive capacity ?

[koltilabs]

Hi,

i have an old Rackmount Terrastation Pro and wanted to replace the Harddrives with newer once. My Question is what is the maximum capacity for each drive, i could not find any Documentation about this.

Can someone help ?

Thanks,
Kolti

It's kind of a tricky question for this generation of device. I would expect it to handle up to 2TB drives without doing anything special, larger drives might work but it would only use 2TB of the drive in that scenario.

The main limitation in that case is that the boot loader only supports MBR partition tables which have a 2TB limit. It is possible to get around that limitation using Hybrid MBR/GPT partition tables which allows the bootloader to see an MBR while allowing the OS to see a GPT (which supports larger drives).

I've used that technique to use larger disks when running Debian on similar devices:

I assume that if you did something similar with the stock OS you could make it boot but since it wouldn't know how to deal with the partition table it would fail to format the drives properly. I've never tried anything like that with the stock firmware.
