Windows 7: Windows 7 stalling during copying of large files to externa

[calix]

I am currently trying to make a copy of the files on my laptop to an external drive but after 1 Gb of data is transferred the status box when copying stops and doesn't seem to be copying over any further files. When I try to cancel the process it does not register that I have pressed cancel and I have to shut off my laptop manually, waiting a few seconds before turning it back on.

I have uninstalled avast believing that it might be causing an issue with the transfer but the result is still the same.

Recently after a failed attempt it has rendered my hard drive back to an ntfs unreadable state due to error code 0x80070570 .

Any help to resolve either issue would be greatly appreciated, thank you.

What is the external HD? How old is it? When was it formatted etc..

In any case I would run a diagnostic on the external drive.
Also try a copying utility such as TeraCopy free version and see if it has similar problems(once the external drive is returned to a normal state or using another drive.)

The hard drive is a Toshiba automatic backup portable drive, it's about a year old I believe, it technically belongs to my boyfriend so I'm not exactly sure when it was formatted last
Sorry for the wait in reply... ^^;

So is the drive hosed now? If you cannot read any files from it and there are no national secrets on it you may as well do a slow format. A slow format takes time but it checks for bad sectors as it goes and writes zeroes to all of them. You have a better chance of having a usable drive when it is done.
