we urgently need help... any ideas?
we have Problems with two identical 4TB harddisks. we use the harddisks only for datastorage, no booting. No RAID.
Only AHCI mode!
The server recognize the 4TB on each drive. When dataspace reach more than 2TB data amount, drive controller get the failure.
It seems that, when we store more than 2TB on the 4TB harddrives, die GPT partitiontable changes to the volume to RAW format and the data get lost.
We use 2 drives, we tested each harddrive. Both drives seems to be ok. And we can reproduce the failure
System Error log found a controller ERROR, Disk , ID:11
Motherboard: S3420GPV S1156
Operating System: Win2008 R2 SP1
BIOS Version: S3420GP.86B.01.00.0053.081120151728, BIOS Date: 08/11/2015
AHCI-MOde check seems ok,
INtel(R) 5 Series/3400 Series SATA AHCI Controller, Intel, 08.06.2010, version: 22.214.171.1242
PLease see attached SERVER01_2.HTM for more systeminformations.
It seems that Intel
S3420GPV cannot handle Harddrives larger than 2TB in AHCI mode ?
Please help, what we can do to get it running...
Feel free to contact us for further informations...
You could give Intel RST 126.96.36.1991 a shot, as it's the last release supported for 'Ibex Peak' chipsets.
Back up your important data first, though. The driver structure changes a bit, because a filter driver is added after RST 11.2.
As Gize2 stated, please try Intel® - RST 188.8.131.521 from
Please let us know of the outcome.
Thank you very much...
At the weekend we installed the https://downloadcenter.intel.com/download/23496/Intel-Rapid-Storage-Technology-Intel-RST-RAID-Driver https://downloadcenter.intel.com/download/23496/Intel-Rapid-Storage-Technology-Intel-RST-RAID-Driver
and made some greater tests... It seems to work... And we now put the 4 TB disks into operation...
We hope the problem is solved now...
Perhaps you can answer to a last question? The controller now use 2 driver files, iaStoreA.sys and iaStoreF.sys.
Please see the attached docx File for the driver constellation from the controller and one of the harddrives.
We hope, that it is a correct combination?
regards and thank's for the fast help...
You were able to successfully set the GPT partition and it should work fine for more than 2 TB drives.
As stated on https://support.microsoft.com/en-us/help/154690/how-to-troubleshoot-event-id-9,-event-id-11,-and-eve... https://support.microsoft.com/en-us/help/154690/how-to-troubleshoot-event-id-9,-event-id-11,-and-eve...
However, the largest hard drives that we have tested on this board is 3TB as mentioned on http://download.intel.com/support/motherboards/server/s3420gp/sb/serverboards3420gplc.pdf http://download.intel.com/support/motherboards/server/s3420gp/sb/serverboards3420gplc.pdf
The iaStoreA.sys and iaStoreF.sys. files are required drivers for best performance.
I checked the /servlet/JiveServlet/download/450180-163837/Controller_Driver.docx Controller_Driver.docx file and it seems it is a good combination.
Please keep testing the system and let me know if the issue is resolved.
