Re: Ubuntu froze when transferring data from corrupted hdd, hdd now unclean
If it gets a drive letter in Windows did you try doing chkdsk /f on it from Windows? That is what gparted generally recommends when it sees a problem with an ntfs partition.
My boss' grandson had the hard drive fail on an old company laptop (WinXP refused to boot, even to safe mode, to protect data). At first I could copy part of it to USB drive using Ubuntu booted from USB. But copying locked up or stopped when it got to the bad part. I put it in an external USB enclosure and neither Windows nor Linux could mount it (I forget if sudo fdisk -l was still working). I let it sit for a couple of weeks and on a whim connected it to my Ubuntu desktop, and I was able to copy most of the user's directory from it except for a corrupted game directory. Sometimes you just get lucky.
The rest of the story: Replacement drive eventually refused to boot due bad sectors, chkdsk /f fixed everything except apparently unimportant dll, used Acronis to image it (file by file, not sector by sector) for warranty replacement drive (clonezilla would not work due to bad sectors). Then warranty drive refused to boot after viruses corrupted it, fixed with chkdsk /f and virus scan. Then the laptop screen got broken. Oh well, maybe he just wanted a newer laptop.
