Partition errors and ckdsk

Hello,

My query concerns my external hard drive, corrupted partitions and chkdsk, with regard to XP. and the panel saying 'Disk in Drive .. needs formatting'.
I am getting this 'needs formatting' panel. Changing the drive letter doesn't help. I have got the same panel for the two external hard drives I have, one an old C drive with Vista on and the other a data store.

I reckoned it might be that the partition is corrupted but when the Vista blue-screened (which it did a few times in the space of a week or so) when I had it as a C drive, it automatically ran chkdsk and found no errors. I am wondering whether chkdsk is a reliable means to tell whether or not the partition is corrupted or whether there is something physically wrong?

Anyhow, I also thought that the fact that both HDDs yielded the same panel meant that my XP installation is unsound, but when I took one of the HDDs (the data store) to the computer shop it gave a 'needs formatting' panel' on their Win 8. I didn't know whether this was a standard thing on Win 8 when you use a USB caddy to try to access a data store; after all they said that the format wouldn't lose me my data (which is not the way it works with regard to Win XP).

If there is something wrong with both HDDs it might be down to the fact that I had ill-advisedly been unplugging and replugging the HDDs when the computer was running, not knowing about the need for a hot-swappable connection. But then I thought that any such damage would show via chkdsk.

Hope someone can help!

With thanks in advance.

It doesn't seem to be a hardware problem because the scan disk reported no problems.There are any programs out there for repairing disk problems. Sound's like a case for a boot sector repair. Google free boot sector repair programs and find one that you like, FIGURE OUT HOW TO USE IT, (I say that in caps because you can mess it up worse if you don't) and you should be able to get it up and running.

Thanks for that but do you mean the boot sector problem, if such it is, is on the OS that I am using or the OS that is installed on the HDD that I am trying to access? It looks like you mean the first of these, but you can't be too careful if you get what I mean :).

If the external hard drive was plugged in to the Windows 8.1 machine and still said "needs to be formatted" then the partition on that hard drive is having a problem. " I should have said partition instead of boot sector, sorry.

Ok, I went back and read it over a couple of times. It looks like the operating system on your machine might have problems and that could have caused problems with the partition on your external hard drive. At this point the external hard drive and the machine must be dealt with separately. You wont be able to fix the partition on the external unless you have a reliable machine to do it from. To fix the operating system on the machine, you can use the install CD or find a free program that will automatically look for problems. That might be easier for you. Lots of programs out there. Without knowing more about the problem I wont recommend any certain one at this point. But if you can Google the problem you will probably find a free program that will help. The external hard drive is probably an easy fix. Again google the exact message or problem and find a repair program. Partition Wiz mini tool might work for you. It is easy to use. If it doesn't work there are many more out there that get into very specific problems. Again you can do these fixes with more rudimentary tools but you will have to know more to do it. It is easier for novices to just find automatic fix utilities and run them.

OK I took the data store disk to a public computer (whose OS was *not*, I think, Win 8). and wired up the caddy. Still the same 'Needs Formatting' panel. I imagine that this disk, if not both of them, were affected by my hot-swapping.
Since this gives me no reason to believe that my current OS is at fault, is it still Partition Wiz that you recommend? What about Partition Table Doctor?
Am I likely to have further problems with the same HDD?
With many thanks.

You should be able to fix it with partition table doctor. Again, there are many programs out there. You can try a "recovery" program to get the data off the disk and then re-partition it and put the data back on. Then it will be stable. Or you might just be able to fix the partition without any further problems. I don't have enough info about your machines operating system and partitions to be able to help with you that problem.
