Ubuntu

data retrieve

Asked by KKevin901

I have a U904/XP dual boot (XP in master HD, U904 in slave; GRUB in master HD). The system working smoothly. Couple weeks ago, it showed error 17 when boot up:

"Grub loading stage 1.5; Grub loading, please waiting...; Error 17" then just hang y there. I replaced the slave HD and re-install U904 on that. The system then can boot up and running.

I read some thread indicating error 17 is caused by MBR and the fix of MBR. But since I have been using the new slave HD and I lost already the XP boot disk. I prefer leave the present config in tag and retrieve the old slave HD data.

Now, I would like to retrieve the data back from the old slave HD. I put back the old slave HD and boot the system with liveCD. The system can then see that old slave HD. But when I try to copy those files from U904 home directory to master HD, a message window pop up saying I do not have permission to retrieve those files.

Any advise how I can retrieve back those data from old slave HD? Thank in advance.

Well, you clearly should see your "old master but now slave" disk in the new situation...

Does upon booting BIOS sees it? If you are not sure then enter the BIOS and look there if it is registered.
If BIOS doesn't see it most probably you forgot to change the pin of the disk telling it's master or slave.

Hmm?..

Yes you should be able to put your new drive in as the master along with the old drive. If you are using sata drives or for some reason the new drive wont bot then just restore the grub and the mbr by doing the old

Tom,

Read the link description, it seems a bit different from my situation. Here are more details.

The HD are SATA types, no pin settings. In my configuration, 1st (master HD) contains XP only, 2nd (slave) HD contains U904. When I install Ubuntu last year, I installed Ubuntu into 2nd (slave) HD but accidentally GRUB was resigned in the 1st (master) HD. This inherent the system can only be booted with both 1st and 2nd HD exist.

I replaced the 2nd (slave) HD leaving the 1st(master)HD in tag. I can now boot both XP and U904 same as before. The only thing left is to retrieve those data from old 2nd (slave) HD.

I tried also to boot the system with only the old HD, but screen just display "GRUB" and hang there. It seems to be looking for the missing GRUB.

Kevin,
when Ubuntu sees a hd it doesn't necessarily mean it is mounted. Did you try mount and chroot?

Sam,

I believe it is mounted. As I can open home folder different directories. When I try to copy particular files then the message windows pops up saying I do not have the permission for that operation as I am not owner.

Via chroot no sudo necessary.
But could it be that you made the folders in home 750 instead of 755?

I remember I did normal U904 installation according to the screen instruction from liveCD. I don't recall there was special setting for home folder parameter. What is 750 & 755?

750 = no access for others
755 = others have access
owner - group - others
4 = read
2 = write
1 = exec
4+2+1=7
4+1=5
