Hi,
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?
The Smart-Report has green marking on all positions.
The Quick-Test failed after a few seconds with the error 07 (failed read test element)
The Extended-Test normaly runs with about 150,000 sectors per second and break down to nearly 0 in an area where the read test with HDDscan also break down with acess times up to 3000ms. I don’t have the patience to wait for the end of the test by an estimated time of more than 5 hours.
After the test abort it has repaired the bad sectors, but HDDScan found them again.
Here is the curious read rate diagramm.
The result: the problem it is not only the disabled write cache. I suppose, there is no way to reanimate the disk.
