Anyone ever had an SATA cable cause data corruption?
ASUS P5K Deluxe WiFi/AP
2GB PC6400 Giel RAM 1x 8800GTS 320MB 3x 500GB HDD Other drives 2x300GB and 1x320GB Is there a chance a SATA cable could be at the cause of data corruption? I've never heard of SATA cables causing problems, they either work or not in my experience. Let me explain... Currently got 3 SATA drives installed on the above system and am experiencing very occasional file corruption issues on whatever drive is connected to the 3rd port (tried 3 different drives) on there. The other 2 ports/drives seem to suffer no corruption. At first I thought it was maybe down to faulty RAM (I had to replace the RAM about a week or so before the corruption started occuring), but numerous long 48hr+ MEMEST86+ session give it the all clear. The corruption seems VERY subtle and mainly when large files are involved, it occurs (or atleast I can detect it) maybe once every 1 or 2 days. I'm using the standard SATA cables that ASUS provide. Any ideas how to pin this down? |

The corruption seems VERY subtle and mainly when large files are involved, What do you mean by that exactly ? Is that only seen when you copy large files or is it also seen when you read just them, and is the corruption permanent when it happens or variable from read to read ? it occurs (or atleast I can detect it) maybe once every 1 or 2 days. How are you deciding that you are seeing corruption ? I'm using the standard SATA cables that ASUS provide. Any ideas how to pin this down? The obvious way to do that is to automate a CRC etc of the file etc. |

I've never heard of SATA cables causing problems, they either work or not in my experience. Let me explain... Currently got 3 SATA drives installed on the above system and am experiencing very occasional file corruption issues on whatever drive is connected to the 3rd port (tried 3 different drives) on there.

At first I thought it was maybe down to faulty RAM (I had to replace the RAM about a week or so before the corruption started occuring), but numerous long 48hr+ MEMEST86+ session give it the all clear. I have had bit-errors in RAMs that memtest86+ did not find. I had to run an unserspace memterster under Linux.... The corruption seems VERY subtle and mainly when large files are involved, it occurs (or atleast I can detect it) maybe once every 1 or 2 days. Can you determine the exact nature of the corruption, i.e. can you compare a corrupted file with an uncorrupted version? I'm using the standard SATA cables that ASUS provide. Any ideas how to pin this down? First, SATA uses checksums ion all transfers, uncaught corruption is extremely unlikely. The suspects a - RAM (memtest86+ seems npt to do a good job anymore today, unfortunately) - CPU (bus/cache) - System bus - Chipset, especially SATA controller Since you have corruption only on one port, I would say the most likely candidate (almost certain) is the SATA controller. All other candidates should cause corruption on the other disks as well. It is possible thet the SATA controller causes some corruption on its 3rd port internally, before the data gets fitted with checksums. Advice: RMA the board. Arno |

Any ideas how to pin this down? Since those cables are cheap and easy to swap, I suggest replacing both the signal and power cables to that HD to see if the problem goes away. Like Arno, I think the other hardware is more likely than cables, but cables are easier to test. The SATA signal cable is even less likely to be the culprit than the SATA power cable; that low-tech power cable doesn't even have CRC. ;-) -- Cheers, Bob |

Any ideas how to pin this down? Compare your good and bad files. You can do this from a CMD window by typing ... fc /b good_file bad_file Consistent differences in a particular bit could point to an error in some data bus. A system RAM error could also produce the same symptom, but I expect this would affect all your ports/drives. - Franc Zabkar -- Please remove one 'i' from my address when replying by email. |
