I own a WD5000AAKX which I use as system drive (WIN7 + UBUNTU). I saw lately some inconsistency (System Boot time from <1min up to >2min so I decided to check the disk.
Using HD Tune Pro I found an error (C7)
I then looked around the forums and the internet and found that this error if stable is not necessarily a problem and can be attributed to other sources (cable etc). I tested with different cable, sata port on the motherboard and all seemed OK (no increase in the number 3274). I also tested the initial cable and sata port with the 500GB AAKS I have as back up to the AAKX disk of interest and both cable and sata port were NOT FAULTY (and still aren’t).
All this was about a week ago and in fact I almost forgot the whole thing, after testing (ALL TESTS) with the WD utility.
Yesterday I tried to backup my AAKX to the AAKS as usual using CloneZilla (as always). Even though the process completed and said OK at the end there were numerous I/O errors on AAKX and none on AAKS. So, I retested the AAKX disk on a different system (W7 32 BIT) and found the same ULTRA DMA CRC ERROR COUNT (which is normal since it is logged in the disk). Digging around I found another program GSmartControl and ran it only to find Prefails and the UDMA errors as shown
So considering a) the drive inconcistency, b) the I/O errors during the backup process and c) the results in the pictures can someone advise me on what to do?
A) RMA the disk
B) Wait for the disk to die and then RMA
C) Continue using the disk like nothing happened
I repeat that the tests with the WD application (Data Lifeguard Diagnostics for WIN) are ALL normal.
I will be more than grateful for any answer/help/advise
