thanks for your answer
I tried to answer yery detailed - maybe this will be helpful to others, if it will lead to success
Do any of the machines indicate the partition type? PPC architecture
[ ..... ]
What are you actually trying to do at the moment? Recover data?
Yesterday evening/night I tried various things with the PPC iBook. None of the actions taken even did recognize the partitions
I downloaded a couple of Live Linux CDs and booted them. Some did boot successfully but did not recognize the partitions
- Ubuntu 6.10 PPC
- a Gentoo PPC (don't know by heart which version)
A very early Knoppix PPC CD does not boot at all
- the MAC OS X was booted instead.
I tried 2 newer (dated from autum 2003 / spring 2004) Knoppix PPC CDs, too. They are listed as "MIB beta" versions, no idea what this means
- Knoppix MIB 10 PPC
- Knoppix MIB 12 PPC
Both did boot, but during the booting process, the screen went black and did not show anything at all
. Though I heard the CD working. Seems, that there is some kind of issue with the resolution or anything similar. But I did not manage tio solve this
. At 2 o'clock I went to bed
Therefore I decided to go one with the PC / UFS Explorer direction.PC Hardware / Windows
As sayed before, the Knoppix for PC harware did recognize the partitions. THe Windows XP did so, too - but it shows only one of the three disks. Here is, what Windows shows:Disk<nr>: 232,88 GB
primary partition: 376 MB without errors (unkown partition)
primary partition: 133 MB without errors (unkown partition)
primary partition: 232,20 GB without errors (unkown partition)
primary partition: 188 MB without errors (unkown partition)1. Attempt
First thing I tried, to get access to all the three disks was, to connect the disks not to a common USB Hub, but directly to different PC ports. Pure try - I know
Doesn't matter with ports I am using, Windows shows only one of the disks (I take a look both at the "Device Manager" and the "Data Storage Management"). 2. Attempt
Next was, to disconnect my IDE dvd drive and writer and plug 2 of the disks to the IDE channel instead. After a few cycles with setting jumpers ans such things, the BIOS shows both disks! As the PC tried to boot from those disks, I had to set the boot disk explicitly to "IDE Master 3" , as my SATA disk are treated as IDE channel 3 devices. OK, windows now booted.
But again, it shows only one disk!! 3. Attempt
But I treid now, to connect the third one by USB to the system. And this works
The -I guess unique- drive identifier in the "Device Manager" shows something like:- Drives
WDC WD2500BB-98GUC0 - USB device
For both disks the partitions are shown. So, I have to figure out, how to get access to the third drive.4. Attempt
What I am actually trying is to clone the entire disk (the partitions) to a 500 GB disk using the clone feature of Acronis True Image. The idea is, that the issues is the drive identifier (means this "WDC WD2500BB-98GUC0" string, don't kno the correct phrase
), as all the three disks would have the same one. By connecting one disk directly as IDE device, and the second one by USB, they are using different ones (see above). I hope, that the hardware of the used disks doesn't matter for the RAID system, its only looking at the partitions. In this case the 500GB disk will be recognized (I have cheked this before) and will contain all the four partitions of the original disk. Now I would be able to get access to appropriate partitions - the second ones, containing the RAID5 data.
The cloning of the disk will take about two more hours it says. I am not able to double-check, which partitions types are shown by Acronis, but I saw something like:- Linux raid (0xFD)
- Linux swap
Therefore I see a chance, that this will work. Next step would be, to try to "build" the RAID5 with UFS Explorer.
I will post my success (or failure
) anyway. Hold on a while
Buffalo at one point modified the superblock ID and I do not know if they did the same on this series. To gain access to the RAID you do need to connect them to a machine with a RAID controller.
Hm, do you mean a "real" hardware RAID? I thought, the TeraStastion internally is a soft RAID. Didn't get your point, i guess
With only one drive out of the RAID you should be still able to operate as RAID5 can sustain a single drive failure.
Yes, that's my hope
Would be great, if this time "hope dies last" would not be the truth
Thanks for your time again & have a nice eastern,
