From my understanding the xbox shut down at 71C, or 159.8F.

I concur that a 7200rpm, 8mb chache drive means better seek times, and overall better performance.  Especially on large, fragmented drives.

I dunno oz_paulb, I wouldnt underestimate the hard drive companies, they sure have come a long way very very fast.

The hard drive manufacturers won't have 2.2TB in 3.5" enclosures by 2005.

RIGHT! so how the hell is Flagg seeing xboxs running stable at 160F?

Actually, the xbox shuts off at 90 celcius.  It's happened to me twice.. fan problems.

I have some "Quantum Fireball" drive.. It gets as hot as a fireball (the case of the xbox actually gets very hot.. and the vent in the back is like a heater), but as long as the fan ran the system was fine.


Great work on all this development.  I'm putting off purchasing my second hard drive until this is released.

Good work Paul!   I'd love to do Beta!  I'm just kinda wondering how hard it would be to apply this fix when it's available?

[GuySmily]

Apparently it's going to be as simple as a checkbox in xbtool (or radio buttons, but..).  And also as he said, hopefully bios developers will eventually implement this into their own bioses, but in my opinion it sounds like with so many options it may stay as a patch to be compatible for more users.  I guess it will just depend on the demand for each option.

QUOTE (oz_paulb @ Aug 31 2003, 04:22 PM) Yes, 2.2TB is the theoretical max drive capacity (since we're only using 32bits of the possible 48bits of LBA48 addressing). Q: Is that a result of the BIOS accepting a long as a parameter in it's disk functions? Could it possibly accept a structure that is 48-bits in total?  That would allow drives up to 144,115 TB or 144 PB.

Throughout the kernel, a 32bit sector number is used for low-level access.

To change it to use something larger would make it incompatible with existing apps.

If we start filling up 2.2TB drives, and it becomes a problem, I'll take another look at expanding it past 32bits.

That's really a great idea - you could have multiple sets of Xbox system partitions (drive C:), and use a partition editor to choose which one should be 'active' for the next boot. I haven't tried it, but there's no reason why the standard Xbox partitions can't be moved around/put > 137GB.  The offsets/sizes were all hard-coded into the BIOS before - now they are just entries in the partition table.  The only thing that is 'hard-coded' is the partition numbers - (example: the 2nd entry in the partition table ("partition2") is always the Xbox system drive (C:)).  That 2nd entry can be changed to point to any place on the drive.  As I said, I haven't tried this, but it should work. - Paulb

I like that idea ...

Would make it possible to have a fully retail C/E drive to play on xbox live (so even if MS scans HD they won't detect anything (unless they go raw axx the drive ofcourse)).
And if you boot your xbox with the hacked bios you get other C/E/F drives with edited stuff.

this is a little of topic but what does live actually look for when it does its search for a mod chip /dashboard

It seems like this would be possible, but it depends on what live looks for.

If they do raw access to the drive ("\Device\Harddisk0\partition0"), then they can scan the entire drive, and all bets are off.

That's why ppl should keep their stock HDD. Add a power switch if possible, swap drives if necessary.

[alphaman]

Is there really a noticeable difference between the 5400rpm and 7200rpm drives?  I would think you may see a difference in maybe the load time of the game, but not actual game play?  Anyone have specific info on this and buffer size?

You can do this already.

XBTool allows you modify the bios to boot from any partition that you wish.  As long as you set it to boot from F, there is no reason to modify anything on C and E.

Still won't help if they check the partition table, but due to the privacy issues involved, I would guess that MS wouldn't scan the hard drive at all for fear of the backlash about privacy issues.

Hey oz_paulb,

Sorry for this post being slightly off-topic. But would it be possible to add support for a second hard drive? For example, DeviceHarddisk1partition0?

Thanks and well done with your work thus far.

[mattg39]

Buttza, that is exactly what I was about to post.  Add a second hard drive where the dvd rom is right now.  Would it be possible Paulb?  This would be great.  Two small cheap 120gig drives or two 300gig hdd's.  


Thanks
