problem with disks (urgent)


hello,

I'm having a problem with hdds. I tried to format a 3to hdd in gpt with seven 64, but since then I'm having problems with my hdds. When I try to connect a hdd, another sometimes disconnect. Also during boot, the computer starts on dvd by default.

So I downloaded ubuntu because I know it's easier to do it from here.

I need your help.
Thanks

Okay, let me make sure I understand you correctly;
You have a 3TB hard disk, that you've create a GPT partition table on. You've created seven 64GB partitions, and now you're have problems with other hard disks, right?

Please bear in mind that there's a difference between a hard disk and a partition (partitions live on hard disks).

Is this an external hard drive you're connecting, or a USB stick? Unless you have a server-class system that takes hot-pluggable drives, you probably shouldn't be direct-connecting disks unless it's supported.

That's a BIOS setting you can change. Take a look at your hardware's user guide.
Conversly, you could just pop-out the DVD that's in the drive.

I'm going to behave myself and not comment on that.

yes, except that I haven't created 64GB partitions. I have created 3 of them, two with 1to and the last one with what's left.

it's an internal hdd, on sata2.


And I meant with windows seven 64 bits.

A quick lesson in BBcode is probably due;
When you want to quote someone, hit the Quote button. If you need to just chop-out a peice of a quote, then copy-and-paste it into a Quick Reply, and surround it with "Quote Tags".
( [QUOTE] Quoted Text [/QUOTE] )

If you ever need to copy-and-paste output from a command or a log file, wrap it in "Code Tags", like this;
Quote:
[CODE]
The text or output that you want to copy-and-paste.
[/CODE]
Now, on with the good stuff.

Ah, okay, this is making more sense now. So you only have one 3TB SATA hard drive. You've cut it up into 3 partitions (roughly 1TB each), and your having problems, right?

Assuming I have this right so far, here's what I want you to do;

Boot the Ubuntu CD/DVD, it should start-up a "Live Linux" session (where it gives you a desktop and all that jaz).
Open a terminal, and type "sudo parted /dev/sda print", then give us the output (wrapped in "Code Tags").

Questions:
You mentioned that (I'm paraphrasing) "they're disappearing when you attach a drive". What's disappearing from what Operating System?
What drives are you attaching?

Okay forget about all I've said, which is rubbish, and let me just ask this:
using ubuntu, how can I initialize and do everything that has to be done so that I can use a 3To hard drive on Windows 7 64bits ?

Partition it and then format the partitions with either FAT32 or NTFS.

The thing is that it's not as easy as it seems, because it's over 2To so I need to do special things to make that work, I just don't know what exactly

And stop saying "To". It's "TB" (if you mean terabytes).

"man parted"

Or if you want to be spoonfed;

1) Find out how big that drive is exactly (in Megabytes);
Code:
sudo parted -s /dev/sdj -- print
2) Create 3 1TB Primary Partitions
(Well, the third one is "what's left of the disk")
Code:
sudo parted -s /dev/sda -- mklabel gpt mkpart primary 0m 1000g mkpart primary 1000g 2000g mkpart primary 2000g -1s* print
WARNING: This will render all data on the hard drive useless!
* = The "-1s" means "to the end of the disk".


P.S: Note to all, some countries say "To" instead of "Tb", and "Mo" instead of "Mb" due to language differences.

Okay, thanks a lot for all these replies.
I read man parted. I could use gparted too, right?

Regarding the command "sudo parted -s /dev/sda -- mklabel gpt mkpart primary 0m 1000g mkpart primary 1000g 2000g mkpart primary 2000g -1s* print", I can see 'gpt'.

I have three questions about that.
First, will this hdd be usable in windows xp 32 and windows 7 32 ?
Second, could I not have just 1 partition of 3TB ?
Third, could I not have 3 partitions of 1TB instead in mbr mode, since all of them are under 2.2TB?

I have another unrelated question. I had already tried to make it a gpt harddisk with Windows 7, by right clicking on the disk. I then tried to use 3 partitions, of roughly 1TB each. How can it be that when I connect this harddisk to my computer, the computer doesn't find the windows system anymore (I only have Windows 7 installed at the moment, so the bootloader would be NTLDR) ? Isn't it supposed to look for a system in all connected hard disks until it finds one? Could this situation have something to with how I connected my harddrives to the motherboard (does the order of the harddisks matter) ? Could it have something to do with the fact that some are MBRs while the new one is gpt ?

Sorry about the poor way I expressed myself in the posts above and in the title. I'm not English native, and I'm not good at computers, the only thing I know is that this is the right place to go to when you have a technical question.
I know I asked a lot of questions, but that's just because I have a very small understanding of all these concepts behind. I would very much appreciate if you could take the time to answer them.

Thank you very much.
