These suggestions: Try different cable. Look if cable connector is connected good with connector on mainbord/harddisk. Try a different controller connection. I've tried a different cable and used a different computer (which is a brand new build), and still get this error on multiple hard drives. What exactly does this error mean? Does this happen to all hard hard drive not drives over time? It's currently happening to my Samsung SSD 250, WD 2 TB, and my WD Green 500 GB. What is the deal. 2 have 1 error, and other has 4 errors. Is this actually an error. MY SSD drive is my main operating system, and from time to time i get random blue screens. Could this be the cause of this? windows-7 ssd hardware-failure sata share|improve this question asked Jan 23 '15 at 1:46 Sickest 2,09121733 I had this when I used a bad cable. Replace the cable and relax. –magicandre1981 Jan 23 '15 at 5:47 I replaced the cable as stated already. I'm relaxed –Sickest Jan 23 '15 at 6:43 @Sickest - the count will not go away once the error occurs. So, changing the cable did the trick. Thus, going forward you have to monitor for increase. If you changed the cable, you will probably find that the count stays the same from here on out. :) –Carl B Jan 23 '15 at 8:42 add a comment| 1 Answer 1 active oldest votes up vote 2 down vote accepted Basically CRC errors are caused by bad sectors or because the drive is not communicating with the computer. CRC tests the data pattern that's on the disk and looks for "illegal" patterns, meaning that the data h

A friend of mine tried the "broken" 20GB HD on a Windows system and said it works fine. We put it back as a secondary drive to our server and everything went OK for another 6 months until a similar message started appearing during booting: spurious 8259A interrupt: IRQ7 hdc: read_intr: status=0x59 {DriveReady SeekComplete DataRequest Error} hdc: read_intr: error=0x04 {DriveStatusError} ide1: reset: success and during shutdown: hdc: status timeout: status=0x80 hdc: drive not ready for command ide1: reset timed-out Additionally there were strange clicking sound appearing. And there is also a problem with spinning down the hard drive: it never did spin down anymore which made the server quite loud during the night. Since RedHat's default 2.4.20 kernel doesn't support laptop mode, we decided to switch the distro. I exhanged that drive for a 6 GB drive and newly installed Suse Linux 9.1. When I copied over the data from the 20 GB drive to the 6 GB drive there were three or four files that I couldn't copy (IO failure). Now I wonder whether the 20 GB drive is really broken or not. From all symptoms it seems very likely yes. Although if its just DMA failure messages, they can be switched off by turning off DMA mode (given as boot parameters: ide=nodma noapic apm=off That makes obviously performance worse. DMA means Direct Memory Access and it means that data c
