ExFat drive reads but doesn't write, is slow
Problem: External HDD reacts slowly when browsing, won't delete files, can only look at them. Chkdsk and any scans won't scan correctly when trying to diagnose the problem
Reason: I'm a regular Linux user, but for things relating to ExFat it seems better to take care of the issue on Windows.
Specs: I have an external my Passport WD Hard drive which I use as backup. One partition, ExFat. Windows 7 Laptop with a Fuduntu Linux and Windows partition.
What I've tried:
on Windows: Administrator, run Cmd, my input:
then after about 5-10 mins, output:
C:\Windows\system32>chkdsk /f i:
The type of the file system is exFAT.
Volume Serial Number is 4F4B-0D30
From then on, light has been continuing to flash on the HD, but the stage never went beyond the label identification. After at least 12-16 hrs the stage that should show progress percentages still has not appeared in the commnad-line output.
Windows is verifying files and folders...
Volume label is CKLEESWDBAK.
On Windows: "fix disk" upon plugin makes 0 progress and hangs from the start.
On Windows: Defragment doesn't see hard drive existence.
On Mac OS Snow Leopard: External HD not even seen. Not even Disk Utility.
On Fuduntu Linux: Mounts. Deletes files. When I want to move files to the external Hard drive, only 24MB of 2.4 GB are quickly copied, it then it slows down to 207.3 KB/s and says it needs 3 hrs for the remaining 2.4 GB. Furthermore the window freezes at times when I want to browse.
Attached I have the screenshot of a S.M.A.R.T disk analysis (CrystalDiskInfo) claiming there's a problem with 'reallocated sectors count' and 'current pending sector count'.
I don't really know what do with that info aside from what I have already tried. Any help on people more experienced than me would be appreciated.
