Windows 7 computer with an SSD.  It freezes from time to time... hard reboots result in chkdsk.

Event log shows many The driver detected a controller error on \Device\Ide\IdePort0 errors.

Moved SSD to another SATA port... same error.

If it's a Crucial m4 SSD, be sure to update the firmware, as discussed in this article:


The drive has been running 24x7 with no issues and excellent performance since doing the firmware update.

If it's not this drive, which one is it? In any case, I recommend updating the firmware for whatever SSD it is. Regards, Joe
The problem is you have one or more unreadable blocks. This is not a cabling or power issue.
What you need to do is
1) FULL backup.  (boot to a USB stick with LINUX if you have to, or windows PE on a CDROM, but consider that every byte of data on the SSD is in imminent danger.
2) Run manufacturer's diagnostics.  They will reveal what is going on and whether or not a firmware update is in order.

NEVER just update firmware, especially if the device is in stress. You may brick it.  
3) check for warranty.
i have had that error myself - and a BIOS update cured it
as you can see, there are quite afew updates for it (cpu microcode)
latest version is 1.B -  what do you have?

what was the problem - or solution?

Here are the details:

I have 6 SATA ports 1-6.  With the SSD in SATA1 and DVD in SATA5 I was getting an IdePort0 error.  I move the DVD to SATA2 and the SSD to SATA4 and the error moved to IdePort1.  Removing the DVD altogether moved the error back to IdePort0.

Thus the IdePorts appear to be virtual and get assigned based on the order of the SATA ports.

Because the error would move based on where I plugged in the SSD I concluded the SSD to be the issue.  I exchanged the SSD and the error went away.

I learned, through this experience, that IdePorts are virtual and follow the order of SATA devices.
thnks for posting the info
