Can you use the latest 2TB drives with HS-DHTGL/R5 with firmware version 2.14? If not, what is the largest size drive that anyone has upgraded to?
It might work, but it hasn't been tested. The most that has been tested is 1 TB drives.
Hi, is there any update on this? I'd like to try 2TB drives in mine also...
This unit can only support 1TB per bay.
I've put the 2TB Western Digital Green drives in ours and rebuilt the array. They show up as 2tb drives, but my RAID array still only shows a total of 750gb. I'm looking for help too. We're on the 1.10 firmware.
While it is teoretically possible the firmware was not designed to support a full 8TB of data, maximum of design was for 4TB of data. If exceeding this there is no guarantees that the unit will work properly
I realize that it's not supported and only 1tb drive per tray is supported. So, if I just replaced the 250gb drives with 1tb drives and then rebuilt the array, how do I get the extra disk spack to show up? I replace one drive at a time, then click on rebuild array until I do this for all 4 drives. Once they are done, it still shows the total disc space at 750gb instead of 3tb.

Once you have restructured the RAID on all four disks you need to delete and recreate the RAID to show the new capacity.

If I delete and recreate it, won't I lose all my data?
yes, but if you want to show the new capacity you have to do it. You should be keeping a backup anyways.

I'm doing a backup to a USB drive now so I can redo the array. 4 hours in and it's only backed up 7gb of 695gb. This is going to take a while.
Did that backup finally finish? Any further status?
The backup took forever and it worked. I copied all my data to a temporary drive. Then I put the 4 new 2TB drives in the terrastation and created my RAID 5 with them. Once they were finally done formatting and such (36 hours) I copied all my data back onto them. I've been reading/writing to it without issue for the last couple days.
So, I upgraded from four 250gb drives to four 2tb drives without issue.
We're on firmware 1.10
HS-DHTGL/R5 1.10
i ahve the same HS-DH2TGL/R5 .with same firmware.:manhappy: and HS-DH3TGL/R5also .so can i upgrade these to 8 tera. unfortunately i had bad luck with my HD-H1TGL.
The HS-DHTGL works with up to 4 TB. Generally, HDD upgrade isn't supported due to it voiding warranty. 6 or 8 TB might work (the key word is might) but is not guaranteed. Are these "eco drives" that you're trying to install?
Just saw you asked what drives I used. I'm using WD Caciar green WD20EADS-00S2B0
It sounds like one lucky soul has replaced all 4 of his drives with 2 Tb drives, and was able to create a RAID5 array, though in his post he did not explicitly state that he got the anticipated 6 Tb of space (3 drives worth of data plus 1 drive worth of parity to allow the array to recover if one drive fails).
OTOH, I' ve been running with four WD Caviar Black WD1002FAEX drives for 18 months without incident, until one of the drives appeared to fail. I asked WD to replace it under warranty, and they did not have any re-certified WD1002FAEX drives to replace it with, so they sent me a WD2002FAEX (2 Tb) drive instead. Unfortunately, I have not been able to make the TeraStation DHTGL work with three 1 Tb drives and one 2 Tb drive. I've tried everything I can think of, including deleting the RAID5 array, formatting the 4 drives, temporarily connecting the 2 Tb drive directly to my computer's eSATA port and filling half of the space with a 1 Tb NTFS partition so the drive would have about the same amount of free space as the 1 Tb drives, re-creating the array, etc. (Yes, all the data are backed up elsewhere, so there is no problem with losing data, unless my backup fails while I keep fussing with this backup device.) I have no problem creating a RAID1 array with two of the 1 Tb drives, but cannot create a second RAID1 array with the 1 TB and 2 Tb drive pair. Of course, my original intention was to create a RAID5 array with all four drives, allowing half of the capacity of the replaced drive to go unused, but no such luck with that (which was actually the first thing I tried to do after replacing the drive).
Under Disk Mangement menu, all four drives are identified correctly (correct type, correct size), and I can format and/or test each of the 4 drives successfully as single drives, but as soon as I try to create a RAID array with two different-sized drives, it fails with an error message:
RAID Array error. The File System or Disk Format is not readable.
Looks like I'm going to have to buy a new 1 Tb drive after all, and put the 2 Tb drive into an external case for extra storage...
Can anyone update on the use of larger drives. I'd like to upgrade my 4 drives.
The 2Tb drives worked out just fine for about a year. I can't vouch for any longer than that as I left the company. But we had 6TB of space.
You had 6TB because you used raid-5? Do you recall what drives you used? I had read somewhere that their could be a power supply issue with larger drives.
Hi! I am searching for replacement/upgrade drives for my HS-DHTGL/R5 - (2.14 firmware) - Presently there is no data on the drive so I can rebuild from scratch. I saw a post here that someone has used WD HDD WD20EADS-00S2B0 with success. I too would like to use 2TB drives but cannot find the afore mentioned drives that are new only used or refurbed. Does anyone have a HHD model that is in current production and not over the moon pricy that will work. Any proven information would be appreciated... The unit has worked great for me but I really need to jack up the capacity a bit. Thanks da capn
I looked for information from my own research and couldn't find it. I was going to replace mine with 2TB drives and was sure it would work from my research. After looking at the price for the drives I decided it would be nearly as costly to purchase a new Buffalo NAS drive. Good luck...
