drive and partition problems

#1 Post by tuxracer »

I want Debian or a Debian-based distro on my Thinkpad T41.

The problem is, I am getting warnings or errors when I check the disk drive.

Both fdisk and sfdisk give similar warnings to do with the cylinder boundaries. I have googled, checked various Linux (generic and specific to distro) forums and I still feel lost as ever.

I am not sure what to do now. I am guessing I might have to reinstall or buy a new drive.

This is my output:
fdisk -l gives:

Code: Select all

fdisk -l  

Disk /dev/hda: 160.0 GB, 160041885696 bytes

Any ideas or recommendations of what to do now?

I basically want a multi-boot setup on this 160GB IDE/ATA drive. Windows XP and Linux. I have Debian on my desktop and have used Linux but I'm still not familiar with the partitions setup. I have used GParted but I am wondering if something is wrong with the disk. I ran some disk diagnostic programs in Windows and one sector was bad. I don't know if that has anything to do with the cylinder issues or if it is just the way I partitioned. Also, I dropped something on the keyboard a while back but the diagnostics test only found the one problem, a bad sector. I have read of the cylinder boundary issues when I googled but there wasn't a universal solution. I have no idea of what to do next so I hope to receive some ideas. I thought maybe reformat the entire drive and start from scratch? I don't know if resizing or redoing the setup will help. Partition 1 is stated to not end on a cylinder boundary so I don't know how to fix that. I tried testdisk but it didn't seem to change anything.

Help?

Is it creating any problems for you? I have seen this before, usually after using gparted, and other than the bother of seeing the message from time to time it works just fine. Unless you are seeing problems I would say just use it.
