My disk size is reported wrong. I'm seeing 79GB but I know it is 250GB. I've read a lot of pages about changing partition sizes, but this is the disk size, not the partition size. I can create a partition of size 79GB, but nothing larger.
Here's the history. I have two 250GB SATA disks. I use one as my laptop internal hard drive, and the other I attach externally with a USB cable. When I want to I can swap them around. But what I usually do is use clonezilla to clone my internal drive to the external one and keep the external one in a safe place. Let's call the internal one A and the external one B or this will get confusing.
Drive A suddenly gave me problems, my machine would only boot to GRUB and no further. This coincided with my swapping the internal drive with yet another drive and swapping it back, so I must have screwed up something there. Anyway, drive A was bad.
So I put drive B into my internal slot, booted and restored my backups. All this worked fine. Now I want to clone drive B (which is my good system disk now) to drive A which is the one that went bad. I don't need to recover stuff from that drive, but I'd like to use it again if I can.
Clonezilla told me the disk was only 79GB. Huh? All the other tools I've used say the same. The most recent one I've used was GParted which allows me to create a 79GB partition on the disk, but no larger.
I'm assuming there is some corruption in the disk geometry or similar. But I don't know what tools do that.
Drive B (the one that works fine) has an msdos partition table. heads 255, sectors/track 63, cylinders 30402, total sectors 488397168, sector size 512
Drive A (the bad one) has an msdos partition 255, sectors/track 63, cylinders 9546, total sectors 153356490, sector size 512. Creating a new one with gparted gives me the same thing. cfdisk, when given different geometry information, tells me I'm trying to use more space than there is.
So, maybe this disk is just toast and I need another one, but is there something else I should try?
Thanks
