Talk:Harddrive

Todo

Need help getting data for the different SKU models and the default harddrive they are equiped with.

There is still some conflicting data to be sorted out, e.g.:

maximum size internal drive

The maximum size of the internal harddrive that the PS3 supports is 1TB (TeraBytes) 

note: this seems untrue as there are several people posting pictures of their external to internal drive mod with a size of 2TB

Personal experience

Using Normal Mode and Recovery - when trying to install a 1.5TB 3.5" drive as internal (using an eSATA cradle)

• Using Recovery it is possible to finish the format of the harddrive until 100%. The system however fails to reboot automaticly after that and halts. When enforced to reboot, it errors out with "Wrong Harddrive".
• When trying all the other Recovery Menu options it errors out with "Harddrive Error 0x8002F281".
• When trying to boot to XMB it also errors out with "Harddrive Error 0x8002F281".
• When replacing the drive for the previous tested 1TB harddrive, it boots without errors to XMB and reports : 827GB free/931GB total

Conclusion

>1TB didn't not work.

Using Factory Service Mode - when trying to install a 1.5TB 3.5" drive as internal (using an eSATA cradle) FSM

• Second try, using Service Mode
• first replacing drive for original 120GB 2.5" and using Factory Service Mode to downgrade to lowest firmware the system can handle (2K slim -> FW 2.70)
  • Result is fine. Log showed no errors : UPDATER_LOG.TXT
• Replaced for 1.5TB 3.5" drive and do exactly the same 2.70 again
  • Result is fine. Log showed no errors : UPDATER_LOG.TXT
• Boot to XMB with Service Mode still activated
  • No problems to get into XMB, but checking System Settings > System Information shows size detection issues:

System Software  Version 2.70
IP Address       xxx.xxx.x.xxx
MAX Address      xx:xx:xx:xx:xx:xx
Free Space       30 G

• Exit Factory Service Mode
  • Blank screen freeze when trying to boot to XMB in normal mode
• Power off and try again gives "system software was not installed correct" error
• inserted USB with 2.70 on normal location and START+SELECT button to let it reinstall
  • Preparing Update counts to 100% and then halts (does not reboot), just like in first trial.
• Manual poweroff and reboot just results in blank screen with no harddrive activity

Conclusion

>1TB didn't not work in normal or recovery mode only with FSM enabled.

Going back to the 1TB and crosschecking

• Replacing drive back to the working 1TB (has 3.55 on it) gives prompt to reinstall 2.70, doing so errors out with "Harddrive Error 0x8002F281".
• Entering Factory Service Mode with 1TB and let it reinstall via lv2diag results fine without errors: UPDATER_LOG.TXT
• Boot to XMB with Service Mode still activated
  • No problems to get into XMB, but checking System Settings > System Information shows size detection issues (the '30 G' seems to be FSM related):

System Software  Version 2.70
IP Address       xxx.xxx.x.xxx
MAX Address      xx:xx:xx:xx:xx:xx
Free Space       30 G

• Exit Factory Service Mode
• No problems to get into XMB, and checking System Settings > System Information shows no size detection issues:

System Software  Version 2.70
IP Address       xxx.xxx.x.xxx
MAX Address      xx:xx:xx:xx:xx:xx
Free Space       827GB / 931GB

Conclusion

<=1TB works fine in all modi.

maximum size external drive

External HDD : You can format it to any size up to 8TB

note: this seems untrue, because when >2TB drives have hit the market, no screenshots of >2TB external storage are known

• sources used: source: http://www.edepot.com/playstation3.html#PS3_Harddrive and euss temp blog
• todo: flush out errors, merging in a readable format

Footnote: maximum supported drive space correlates to support of 512sector (either native, or emulated), see: http://en.wikipedia.org/wiki/Advanced_Format

AES-256-CBC versus AES-256-XTS

There is conflicting mention of sources for the algo/mode used for GameOS encryption.

Fact:

• Sony/IBM loves AES
• 256bit based
• sectorsize 512 bytes (4096 bits)
• blockcipher
• recurring patterns are seen

Reference:

• CBC - Cipher-block_chaining mode
• XTS - XEX-based Tweaked CodeBook mode

Experimental Tables

HDD 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 padding between regions defined in "HDD Partition Table" seems to be 0x8 sectors size (see graf notes) but the padding can be different when using unnofficial rebuild methods (create_hdd_region.sh adds a padding of 0x8 before and another 0x8 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 0x20 ? (displaced 0x8 sectors by "HDD partition table" + 0x10 ??? + 0x8 ???)
    • NOR: ps3db region starts at sector 0x80018 (displaced 0x8 sectors by "HDD partition table" + 0x80000 by vflash + 0x10 ???)

• 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)

• 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
