after update to 11.04 no access to a diskdrive
updated from 9 lts to 11.04
had a drive which showed two names (don't askk why and how because I dont know and I an using this drive some years this way)
one is hitashivideo and the other hitashivideo_ the hitashivideo does not contan any file as I never was able to write to it. the other (hitashivideo_) contains my data.
after updating the system only showed hitashivideo and it was not alowed. I aplied chown on it to own it and I was able to list the files (actualy I do know that there are no files and this was shown to me.)
question: how can I get acces to "hitashivideo_" which contains my data.
thanks for help.

aditional info:
the "disk utility" of ubuntu says guid partition table and says unalocated space, names it /dev/sdb and says it's healthy
hope this helps a bit
thanks

well it is a drive: /dev/sdb
and as I said under 9.04 (I supose it was that brand) I had acces with hitashivideo_
on the same phisical drive was another partition (I dont know why and how it happened that I got 2 partitions one names hitashivideo and the other one hitashivideo_)
I never was able to use hitashivideo and as the drive had data and it didn't disturb I simply went on using
dont know if this helps

"WARNING: GPT (GUID Partition Table) detected on '/dev/sdb'! The util fdisk doesn't support GPT. Use GNU Parted."
You don"t have on sdb the classical DOS partition table, but a new type rarely used today.
Could you run "sudo parted -l" instead of " sudo fdisk -l". As I haven't such a disk, I can't check.
If this fails, could you run:
sudo apt-get install gparted
and then System-
This GPT format (also called EFI) is used on Mac and a few Intel motherboard. What is the origin of the disk ?
N.B.: some disks have a read-only partition on which are installed some software and drivers to use it.

I bought and installed the drive.
possibly I formatted o not (I cant remember)
the data on the drive is valuable and I do want to recover them
It did work well on this computer, hence I first used it on annother

question
if I do either of both you suggested (Could you run "sudo parted -l" instead of " sudo fdisk -l". As I haven't such a disk, I can't check.
If this fails, could you run:
sudo apt-get install gparted) do I risk to loose dta
yhanks for your answer

No. "sudo parted -l" where "-l" is lower case "-L" will simply list partition table. For Gparted, it will do nothing if you DON'T click on green check.

follow up:
the good news is that I succeded the following morning to access the drive and partition (by mounting it with the "disk utility", I opened by chance, and as it gave this option I klicked) hitashivideo_. This means I have the data without any loss (lucky me). it took more than 6 hours to copy the whole lot from the PATA atached disk to an external USB3(wondering why it took so long).
the bad news are:
- today I started the computer and I no more am able to access the hitashivideo_. cant mount it with "disk utility" as it (the hitashivideo_ partitiomn) is no more seen by the program.
- I cant remember what I did the night before, in extensis what I did to enable the access
now as I have the data and I do not urgently need the space I am disposed to investigate this if it is of interest, otherwise I format the drive and stay happy
delance thanks for your help

Simpler is to format in DOD partition format. This one has some drawbacks and is outdated, but it is well supported.
Can you help with this problem?
