Xw8600 AND 5TB hard Disk Problem

[MaAlgendy]

Hello,

I got a 5TB from a friend that i need to add to my xw8600 workstation . I tried to connect it in several sata ports . sometimes it gives only 500GB in windows and finally i found that if i connect it to the raid sata ports it give me max 2TB.

Any advice to make it see the total 5TB

You will have to format that disk using GPT in order to see more than 2GB, and if you have to set it up as RAID, or something else like that, the tool you then use for RAID formatting must also support GPT.

Older formatting tools only support 2GB partitions.

Thanks For your Reply.

i tired to delete old partitions and convert the Partiton table to GPT  from inside windows but it still no cahnge as windows is only see it as total cabacity 2TB that can work with  even when it is not formated .

the mother board has 6 Sata sockets and 8 SAS connectors which belongs to the LSI Raid controller.

if i connect the hard disk to the sata sockets it only see it as 500GB in  the bios and if it is connected to the sas ports it see it as 2TB even in any other os like ubuntu .

the hard disk model is TOSHIBA MD04ACA5.

Bios version 1.46

This link will give you some perspective,  HERE.  The storage controller has some limitations that are difficult to surmount.  It works fine with a HDD that is about 2 TB or less, but bigger is an issue.

One idea I just never have gotten around to is placing one of the Texas Instruments HP USB3 PCIe cards in the lower of the two video slots (to get PCIe generation II bandwidth) and have a high TB HDD like yours hooked to that internally via a SATA to USB3 adapter.  You can buy those with 12V DC power adapter, and my idea was to tap into one of the 12V DC "molex" or SATA power ports coming from the workstation's own power supply.  That would be an easy little modification from a few spare parts.  I was going to try the Anker adapter Paul Thurrott talked of in an article  HERE.  I got two of those, and they are high quality.  You can buy the adapter itself without the little power supply to cut costs down to about $10.00 USD, from Amazon. 

That would give you an internal positioning of the 5TB HDD, plus the speed of USB3. 

Alternatively, you also could try a PCIe SATA III card in that same slot (only the two video slots are PCIe Gen 2 in the xw6600/xw8600).  The rest are PCIe Gen 1 (as are all the PCIe slots in the xw6400/xw8400).  That approach would provide you with a more modern storage controller chipset (on the card) and associated drivers, hopefully allowing you to go above the current built-in hardware's limitations.  I don't have a card to recommend, however.  HP used to sell a few as options.  Dan-WGBU, our favorite HP engineer, posted on those way back.

I'd appreciate hearing how you proceed.....

Hello,
I see that you possessed one xw8600.
Installed(Settled) you win10? Because I have small one concerns(marigolds), ilne confirm not of AHCI, nevertheless bios is good in RAID(TREK) and AHCI

Had you this problem?

Thank you has you.
