my WD15EARS seems beginnig to die: some files are unreadable, many bad sectors. All Smart-Tools report problems with too many: Reallocation Sector Count, Reallocation Event Count, Current Pending Error Counts and Uncorrectable Error Counts. But the WD-Smart-Repot reports all is ok and under the limit.
I succeed in bringing the Current Pending Error Counts to 0 by deleting all files und erasing the disk with HDDScan (I am skeptical it was a good idea). Within this procedure the writing rate suddenly break down to 10% and remains by that smal rate with all following write operations (e.g. Windows copy).
By disabling and subsequent enabling the write cache with Windows-XP the writing rate ist ok for a short time, but break down again within the copy procedure. I could see the disabled cache in the Info from HDDScan.
Can somebody help me? Is there any recommended action?
