I have a dell laptop running Windows 7 and lately it has been slowing down quite a bit. Whenever I try and open any window it always hangs and says not responding. I ran diagnostics and memory is fine but had stalls when i tried to run chkdsk. So I ran HDtune and found some errors :
Reallocated Sector Count (current=100 Worst=100 Data=29)
Ultra DMA CRC Error Count (current=100 worst=100 data=52983044)
and when running error scan, it came back with 10.5% Damaged Blocks.
Is this the cause of my hanging?
Does this mean I need to replace my HD or can I just reinstall windows?
Which SATA controller does your motherboard use? What do you see in Device Manager?
I ask this because some controllers have a bug that results in numerous UDMA CRC Errors.
I would also run the internal SMART self tests, eg DST. This test scans the drive without sending any data across the SATA interface. It could be that the 10% error rate for your surface scan is due to interface errors rather than bad sectors, in which case the DST will help to narrow down the fault.
If you have backed up and you are prepared for a failure, you could probably try doing a clean install before throwing in the towel.
Try doing a slow format on the disk and then installing again. If the errors persist then just ditch the HDD and get yourself a new one. Drives don't fail that often but it really sucks when they do...
The "UUTUSBTM-DEVICE_INITIALIZATION_FAILURE" is a red herring. It is telling you that the system cannot find the "Master I/O board". Apparently this little board is responsible for fan control and temperature sensing. It appears to be internally connected to a USB port on the motherboard. Perhaps you disturbed the connection?
