HDD interface compatibility for D820 systems?
I have a D820 -- I ordered it with the 100GB 7200 rpm drive (HTS721010G9SA00) which has as its interface "ATA/ATAPI-7 T13 1532D revision 1" I've bought several aftermarket drives for this system and my older C610s, but all have been 120GB and less, and ATA-6 interfaces. I usually purchase from newegg.com, and they list available interfaces as ATA-6, SATA 3.0Gb/s, Serial ATA-150.
I'm interested in replacing my 100GB system disk with a 200GB 7200rpm disk (HITACHI Travelstar 7K200 HTS722020K9SA00 (0A50940) 200GB 7200 RPM 16MB Cache Serial ATA150 Notebook Hard Drive) but the only one available is listed as having a "Serial ATA150" interface. Yet one reviewer says "works great in a latitude" (not specifying which latitude of course).
Also, I note that in Wikipedia (http://en.wikipedia.org/wiki/ATA-6), ATA-7 is listed as having a "transfer mode added" of "SATA/150" (listed in the table near the bottom of the page).
So, my questions:
1. which of the above listed interfaces will work with the disk controller embedded in my system's chipset?
2. what's the largest hard disk that the bios & disk controller in the D820 can handle (e.g. 120gb, 160gb, 200gb, 250gb, etc)?
3. do you think the "HITACHI Travelstar 7K200 HTS722020K9SA00 (0A50940) 200GB 7200 RPM 16MB Cache Serial ATA150 Notebook Hard Drive" will work in my D820?
4. what about a 250GB drive in the modular bay? (I currently have a 120GB in there)
thanks, foobar1

> The D820 uses EIDE (NOT SATA)
From what I can figure out, this assertion is untrue. See..
http://en.wikipedia.org/wiki/Enhanced_IDE
..and note this..
Enhanced IDE (EIDE) — an extension to the original ATA standard again developed by Western Digital — allowed the support of drives having a storage capacity larger than 504 MiB (528 MB), up to 7.8 GiB (8.4 GB). Although these new names originated in branding convention and not as an official standard, the terms IDE and EIDE often appear as if interchangeable with ATA. This may be attributed to the two technologies being introduced with the same consumable devices — these "new" ATA hard drives. [1]
With the introduction of Serial ATA around 2003, conventional ATA was retroactively renamed to Parallel ATA (P-ATA), referring to the method in which data travels over wires in this interface.
Note also..
http://en.wikipedia.org/wiki/Serial_ATA
The standard interface for SATA controllers is Advanced Host Controller Interface (AHCI), which allows advanced features of SATA such as hot plug and Native Command Queuing (NCQ). If AHCI is not enabled by the motherboard and chipset, SATA controllers typically operate in "IDE emulation" mode which does not allow features of devices to be accessed that are not supported by the ATA/IDE standard. Windows device drivers that are labeled as SATA are usually running in IDE emulation mode unless they explicitly state that they are AHCI.
See also this table..
"ATA standards versions, transfer rates, and features"
http://en.wikipedia.org/wiki/Enhanced_IDE#ATA_standards_versions.2C_transfer_rates.2C_and_features
My present drives identify themselves (via SMART) as "ATA/ATAPI-7", which that table identifies as "SATA 1.0".
Also, I have hooked up an external 250GB HDD via USB2 and formatted it successfully (I'm running Ubuntu GNU/Linux v6.10) -- though I wonder if any (S)ATA/EIDE limitations are mitigated by having accessed the drive via USB.
Has anyone stuck a drive > 120GB internally into a "C" or "D"-series Latitude and have it work? I.e. you are able to access all of the drive's capacity?
thanks,
foobar1

So it seems I *will* get that 200gb 7200rpm disk and expect that it will work just fine.

Hi, the potential BIOS ATA restrictions are a non issue for modern
Operating Systems. This applies to Linux, but to Microsoft, just as well.
All you need it that Linux can recognize "some partition" to boot from,
via the bios. This can be small and within the (say) first 120GBs. ;-))
After this, the OS itself will control any harddisk you might have.

So I've AFAIK figured this all out a while back since initiating this thread, but thought I ought to post a followup. The disk that came stock in my D820 is a Hitachi is a "Hitachi Travelstar 7K100 Hard Disk Drive" (identifier: "HTS721010G9SA00"), which can be easily enough determined by simply pulling the silly thing out of the machine, or in GNU/Linux using the "lshal" command and grepping for "storage". The 7K100 data sheet is here: http://www.hitachigst.com/tech/techlib.nsf/techdocs/50C8DBC2A315A4C786256F400065B756/$file/7K100_SATA_FINAL_DS.pdf
So, in terms of what interface is being used in the D820, the datasheet clearly shows the disk interface connection to the hard disk itself is SATA 1.5 GB/s.

That is correct - the post above is not. The D820 primary drive is Serial ATA (SATA). The Media Bay (secondary) drive must be EIDE, and all the prior D8x0 systems did use parallel ATA for both (i.e., the D800 and D810).

Thanks for your input/help husky0894
> the post above is not
by that, I presume you mean the post above by ejn63
> The D820 primary drive is Serial ATA (SATA)...
ok, thanks for the confirmation. It seems though that the second-order question is whether a disk that is identified as having a SATA 3.0gb/s interface will work in the D820, do you know and can you point at confirming information?

So I'm curious about where one can find such information?
thanks again for your help.

[updated 5-Jan-09] Ok, it seems that the SATA interface designers made allowances for backwards compatibility and there's a reasonable chance that a SATA 3.0gb/s drive will "just work" with a SATA 1.5gb/s motherboard interface:
Serial ATA: Backward and forward compatibility
http://en.wikipedia.org/wiki/Serial_ATA#Backward_and_forward_compatibility
Note that that page lists specific chipsets that do not feature automatic compatibility, but I do not think they are used in D820s (AFAIK it's all Intel chipsets (ah, the "lshal" command shows that the chipset is Intel "82801GBM/GHM (ICH7 Family) Serial ATA Storage Controller IDE") ).
Confirmation of successful use of a SATA 3.0gb/s drive (e.g. Hitachi TravelStar 7K320) in a D820 would be great to hear about, if anyone can confirm, thanks.
[updated 5-Jan-09, again] I found a "Compatibility Summary" document by Hitachi wrt their 7K320 drive..
TS7K320_CompatGuide
http://www.hitachigst.com/tech/techlib.nsf/techdocs/7D1EFC63FD527E358625743D0081CAFC/$file/TS7K320_CompatGuide.pdf
..which lists the D820 (and D830) as compatible, along with a slew of other systems.
[updated 22-Jan-09, yet again] So, I did indeed get a Hitachi 7K320 drive which is billed as SATA 3.0gb/s and installed it in my D820 after having partitioned it and copied over my system partition (using GParted live CD) with the new disk being installed in an external USB-attached enclosure (this one -- Eagle iNeo NA302U 2.5" SATA enclosure -- which works fine). Afterwards, after installing GRUB on the new disk, I installed it in the D820, booted it, and am all set -- it seems to work fine.
