chkdsk

write

I've recently faced a strange problem. I use Directory Opus file manager that suddenly started to report an I/O error when trying to copy files onto one of my disks. The Windows Explorer did copy those files but it was extremely slow.

I run chkdsk on this drive (ca. 300GB) and it took it over two days to complete! However it reported no errors found.

I run Hard Disk Sentinel that says the drive is OK.

But the files still read and write extremely slow! Can anyone advise me what to do? I have a spare space I am copying my files for backup now but should I get rid of this disk? Or can I try to "heal" it somehow?

Many thanks for your ideas!
