=== maximum size external drive ===
=== maximum size external drive ===
Maximum size is 2TB.
PS3 can only read drives using MBR (Master Boot Record) partition table.
MBR maximum drive size is 2TB (with up to 4 partitions).
PS3 cannot read drives using GPT (GUID Partition Table).
GPT has maximum drive size around 256TB, although in practice it may get tricky beyond 15 TB.
<pre>External HDD : You can format it to any size up to 8TB

== Tests increasing the max HDD capacity supported by the firmware ==
Successful 2Tb installation confirmed personally. (warning: "restore filesystem" a.k.a. "filesystem check" was not tested. Without this function the hdd will cummulate filesystem errors up to a point where the PS3 will welcome you with a warning message telling "the hdd needs to be formatted" and you will lose all the contents of it)
*HDD was Toshiba MQ01ABB200 and PS3 was CECHK04
*Flashing to 4.46 OFW and reducing 2Tb hard drive to 3633537126 sectors via "hiding" rest via HPA on PC (formatted first to FAT format on MAC a whole device and GPT instead MBR) with HDAT2 so PS3 sees its as 1732.6GB Hard Drive and did succeed formatting.
*After 4.46 you can upgrade to latest 4.82 Firmware back and continue using it. 4.82 firmware says after HPA sector hiding that it is "unsupported" but 4.46 doesn't and can format it.


Pictures of some of this of my personal confession and proof:
== AES-256-CBC versus AES-256-XTS ==
[https://twitter.com/XantheFIN/status/1022873742538682368]
Original info i used to confirm:
[http://www.psx-place.com/threads/ps3-1-75-tb-internal-hdd-upgrade-formatting-utility.11989/#post-100471]


Note from another tester :
While the above seems to work, using 4.46 to allow 1.75tb leads to errors after saving a few games : the console stalls, then takes forever to recover (if it recovers). I tried reducing to 1.5Tb, and none of the errors show up.
What's misleading is that 1.5Tb is in fact recognized by 4.82+, even with HPA.
I think the safe way to get the max capacity is to use HPA, but stick to something between 1.5Tb and 1.75Tb and make sure it's recognized by 4.82+. It means downgrading to 4.46 is not necessary (and mostly misleading).
== AES-256-CBC versus AES-256-XTS ==
There is conflicting mention of sources for the algo/mode used for GameOS encryption.

===HDD partitions table info ===
*This table (pretends to) show all the posible partition layouts in all PS3 models, even when there are 2 big differences that changes partition positions (and consequently region names in Otheros/linux)
**Flash type
***NAND flash 256mb - All firmware is stored in real NAND flash
***NOR flash 16mb - A small part of the firmware is stored in real NOR flash, and most of the firmware is stored in the first "virtual flash" (ps3vflash) partition in HDD (his position makes the other partitions to be displaced)
**OtherOS bootloader installation (usually petitboot or kboot)
***OtherOS bootloader official - petitboot is installed in region (1.5), his size is smaller than the region so no need to resize
***OtherOS++ bootloader unofficial - petitboot is installed in region (1.5), his size is bigger than the region so the region is resized conveniently (usually up to 8MB = 16384 sectors)
**OtherOS installation
***OtherOS official for NAND models - Linux/FreeBSD installed at region (3.4), last region of the HDD
***OtherOS++ unofficial for NOR models - Linux/FreeBSD installed at region (1.7), last region of vflash is created and resized conveniently (firmware installers doesnt creates this region)
***OtherOS/OtherOS++ unofficial for NOR/NAND models - Linux/FreeBSD installed at region (3.4), last region of the HDD
*Devices contains a single physical partition
*Physical partitions contains one or more logicall partitions
*Padding Notes:
**7th region of vflash (ps3vflashg) ends at sector 0x77E00. vflash is 0x80000 sectors size, so the "not used area" after ps3vflashg has a size of: 0x80000 - 0x77E00 = 0x8200 sectors = 17039360 bytes (16,25 MB)
**The official padding between HDD regions defined in "HDD Partition Table" seems to be 0x8 sectors size (see [http://www.psdevwiki.com/ps3/Hypervisor_Reverse_Engineering#HDD_device graf notes] and the example below) but the padding can be different when using unnofficial rebuild methods ([http://gitorious.ps3dev.net/ps3otheros/scripts/blobs/master/create_hdd_region.sh create_hdd_region.sh] adds a padding of 0x8 sectors before and another 0x8 sectors after the new region, concatenating new regions with this script generates double padding). Or when modifying the "HDD Partition Table" manually is posible to remove all padding then let the system generate the new region by himself
**VFLASH displacement
***NAND: ps3db region starts at sector 0x18 (displaced 0x8 sectors by "HDD partition table" + 0x10 by ?)
***NOR: ps3db region starts at sector 0x80018 (displaced 0x8 sectors by "HDD partition table" + 0x80000 by VFLASH + 0x10 by ?)
*Sector backup/restore tips
**There are some specific sectors that contains criticall data or are prone to be lost, sectors can be regenerated by having the related keys, or can be overwritted from another hdd formatted in the same PS3 (all hdds formatted by the same PS3 shares the same encryption with the same keys)
**Some users lost the "HDD partition table" when connecting the HDD to a windows PC, because windows will try to "initialize" the HDD, and this initialization implyes to write an MBR of size 1 sector (so if the user accepts the initialization the first sector of the HDD will be lost). This can be solved by connecting another hdd to PS3 and allow PS3 to format it (this regenerates the HDD partition table), then is posible to connect the HDD to PC and "backup" the first sector with a hexeditor (like HxD)... this sector can be used to repair the other HDD. This process doesnt needs any key, is just a copy-paste of sectors from 2 HDD's
**When the "boot otheros" flag is used under GameOS, but the petitboot partition is damaged, or petitboot is not present, corrupted, etc... (or when failing at updating petitboot) the console enters is a loop/brick where the bootchain tryes to boot from petitboot, but the system is not able to find it. To fix this problem is needed to "regenerate" the contents of the petitboot region in PC as explained here: [[Mounting_HDD_on_PC#Making_Changes_to_cell_ext_os_area_VFLASH_Region | how to fix a corrupted petitboot region in PC]]. This process needs the keys
**Alternativelly, is posible to make backups of this criticall sectors in PC just in case some day are needed. Having the backuped sectors the fix consists simply in a copy-paste of them, no keys needed
*Encryption Notes: ?????
**Encryption is made "by sector" (data is accessed in chunks of 512 bytes and encrypted/decrypted individually), applyed "at write time" (only used sectors are encrypted), and "by device" (real and virtual devices). In the practise this means for PS3 NAND models all the HDD sectors are under 1 single encryption layer, but for PS3 NOR models (with a "virtual flash device" embedded inside "real hdd device") there is a "top" encryption layer over the whole HDD, and a "bottom" encryption layer over VFLASH (or in other words... in NOR models the sectors inside VFLASH are encrypted 2 times)
**HDD encryption layer (top), based in the '''ata-data-key''':
***FAT-NAND (no vflash): AES-CBC-192 (ata-data-key and zeroed IV)
***FAT-NOR (with vflash): AES-CBC-192 (ata-data-key and zeroed IV) ?
***SLIM-NOR (with vflash): XTS-AES-128 (ata-data-key and ata-tweak-key)
**VFLASH encryption layer (bottom), based in the '''encdec-key''':
***FAT-NOR (with vflash): AES-CBC-128 (encdec-key and zeroed IV)
***SLIM-NOR (with vflash): XTS-AES-128 (encdec-data-key and encdec-tweak-key)

Without patch recovery will throw this error when hdd capacity is above 1,649,267,441,664 bytes. With patch error will be shown for hdd above 2,130,303,778,816 bytes. 1,75TB limited drives should be accepted again. Untested on real hardware, use with caution (hw flasher required)!
