Currently the only model that has been dissect (confirmed on Youtube) is Seagate Expansion of which is the cheapest among all the series.
I'm not too sure about the Slim series and beyond though so keep an eye on.
Seagate Expansion has 2TB model... 2TB on laptop anyone?

Youtubed a bit and found this...

2TB still new in market, and price probably will be pretty high.
You can always import from Amazon or Ebay? But of course as you're concern about warranty, it's not worth the while even it's cheaper to buy through them.

Allow more space than 2TB?
Latest Intel storage chipset driver?
GPT formatted?
Erm, what's more need to be considered?

Probably due to newly release drive, there's not much info on the web other than DOA and bad sectors drives appearing.

Erm, my Windows 7 has no issue on several 3TBs, perhaps you should check if your BIOS able to locate the 3000 GB or not?
Disk Management should able to see 27xx GB unallocated, should use GPT when initialize.

FYI I also has the 3TB purple.

Check the health of your hard disk, use HDDScan or any other software that can extract SMART info from your hard disk, then look at few of these attributes with keyword "sector", such as "Reallocated sector count" (worst possible case), "Pending sector count".
If there's any number other than "0" then backup all files from that hard disk to other hard disk. Look for software that can wipe your hard disk, usually format won't be enough to clear the "Pending sector count" flag, if the "Reallocated sector count" flag is increasing after you do wiping, proceed to RMA your hard disk, you can't rescue such severe damage.
This is an usual sign of failing hard disk, your case may be different, but you may try out those method as I faced this quite few times from my own hard disk and my time as technical support.

Ah... I think I've mentioned to backup anything from the hard disk before you going to wipe but well, do try to backup as many as possible since the Chkdsk may have destroyed most of the data by now; worst options ever to attempt to recover a bad sectors hard disk (from many experiences).
Lets assume the numbers at the "Reallocated Sector Count" is higher than 10 or 20 (Ex. 0x00000010), it's confirmed to be able to claim RMA, no need the hassle of performing any wipe unless you have sensitive data inside.

Wipe software,
1) WDC HDD support software has the option to do so, but I didn't use it for long time so not sure how to access the feature.
2) http://hddguru.com/software/HDD-LLF-Low-Level-Format-Tool/ 50MB/s limit for free version, suggested for 1TB and below HDD, took 1 night to finish, 3TB may takes up to 1 day .

Good luck
