Hi,
First of all please accept my apologies for posting to this list on this
particular topic, but it was the closest match I could find.
I pulled the harddisk out of my ps3, because I have forgotten the root
password on the linux partition.
After spending some time googling I see that the harddisk is encrypted
and there are no linux utilities that can read/write it.
However I did find that the "testdisk" program finds the linux
partitions on the disk (see below.).
It seems I should be able to mount the partitions on my linux pc box
somehow since I now know their location on the disk.
Does anyone know how one might go about that?
Thanks!
Fred

The harddisk (80 GB / 74 GiB) seems too small! (< 13 TB / 11 TiB)
Check the harddisk size: HD jumpers settings, BIOS detection...
The following partition can't be recovered:

Now you know the offset of the Linux "partition" on the disk (i.e. the
part of the
disk that was visible to Linux), you can use dm-linear to map this part ont=
o a
new block device.
After that you can use kpartx to create block devices representing the
individual
partitions on the above new block device.

Why doesn't init=/bin/sh work on the ps3?
