Partition Table Problems?


Below is a portion of my fdisk -l output.

I have never seen the bit about the cylinder does not end on boundry?

This is my first hd and I just re-installed winxp(hdc1).
all of the linuxes in the other partitions still boot and so does win.Do I need to do anything or just not worry about it?

Disk /dev/hdc: 82.3 GB, 82348277760 bytes
16 heads, 63 sectors/track, 159560 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes

Device Boot Start End Blocks Id System
/dev/hdc1 * 1 40635 20480008+ 7 HPFS/NTFS
Partition 1 does not end on cylinder boundary.
/dev/hdc2 40636 154335 57304800 5 Extended
Partition 2 does not end on cylinder boundary.

well i think the + sign with every partition shows that its actually bootable and if i am correct or not , just scan you harddisk partitions , i would say if its working fine , let it work but you should re -partiton your disk the first moment you get

Well, if everything is working, stop worrying, you don't need to do anything.

I think this is simply more evidence that Windows does not play well with others. I also have a dual boot computer. After I had installed Windows 2K Pro, I found that there were a few sectors of free space left empty. When I tried to install Linux, disk druid mistakenly labeled the free sectors along with the entire Windows NTFS partition as free space. Once I used a partitioning program (Ranish Partition Manager) with more control over where the partitions began, the problem went away.

Actually, the '+' indicates
the "cylinder does not end on boundary" problem.

It's the '*' that indicates "bootable".

My hdc2(extended partition) does not have a "+" after the blocks either but has a warning?

Sorry to keep asking but i've been googling and am not satisfied yet with my understanding of blocks and cylinders and in particular the + after the size of some of the partitions.I dont guess there is an easy explanation?

Thanks

The "+" means the partition occupies something greater than the number of blocks shown.

EASY explanation?? Maybe not, but cylinders, heads, and sectors are clearly defined. Google will find it.

What did you use to partition your hard drive? I've found that gparted (the live cd) does well. I believe the '+' in the above lines indicates a boundary that has gone over the limits set by your partitioning.
My advice would be to download and burn to cd the live version of gparted, back up all of your data (burn all files to cd or dvd), be sure you have all of your installation media on hand and reparttion your hard drive. Then reinstall your OSes and reload your files.
Repartitioning should fix the issues with boundary overruns.

If I read the OP correctly, the system is working. If so, then leave it alone!!
Why would a partition going past a cylinder boundary be an issue?

yeah i have that same + thingy and i wont do anything since i used DISKMANAGER to partition my harddisk , i guess its a problem that we should over look
as theres a great quote in URDU (my national language )
which means "you cant drink tea if you see a fly [bug] in it , if you dont see it and its still there you drink it , but if you see it , you cant "
i guess i would still drink it

I've got LOTS of those "+" signs. Who cares?! Everything works fine. I've got partitions that were done via DOS Partition Magic, some via Debian's install routines, and some via manual cfdisk's I've run.

I think I'll just turn off the lights (so I cant see the fly) and enjoy my tea !

Now to confess what really happened.I have 2 ide drives and just got my first sata drive.I wanted to make a 30GB ntfs partition on the new sata for more win storage.

For some stupid unknown reason I grabbed a win98 boot floppy I havent used in years and tried to fdisk the sata.
Since the fdisk didnt see the sata I decided to delete 3 10 GB partitions on my second ide that all had bootable linux os's BTW and make one ntfs.Well it did something.On re-boot I was informed that I had 2 extended partitions on my second ide for a total of 5 primary partitions and this was not cool.so I lost 14 parts and about 8 linux os's on my second ide!

The crazy thing is for over a year the only partition utilities I have used have been gparted 2.4-2 I have on mini cd or mandrivas,I'm not even sure what it is but it works good.I'm sticking with one of the 2 from now on.
gparted has a new release btw.2.5-1.

Oh well live and learn.Thanks for the info and the advice.

Deleting partitions does not delete the contents.
If you can recreate the partition table (and the information is on this thread, right?), then everything will still be there.

I have a fdisk -l printout from just prior to the mishap.

I have only formatted a small portion at the beginning of this drive and made 2 partitions so I should be able to recreate my old partition table and all my os's still be there?

I think I'll try this.

I'm not taking a chance of permanently damaging my hd by manually setting the beginning and ending blocks of a partition am I?(If I can even do it)

Thanks

I've never restored a partition table, but restoring one should have no damaging effects on your hard drive, I should think. As for manually setting the beginning and ending blocks, I do not know. I wouldn't think so, but you may want to google it and read all available information before you commit to any action.
