June 2009 22:13:43 This is one of the most frustrating error messages you can ever deal with. Sometimes the fix windows cannot access the disk is simple, sometimes it's a complete pain.

Your data is likely http://www.tomshardware.com/forum/250364-32-solution-disk-read-error-occurred safe and sound. Here's how we'll recover your data. Try each step below, in order, and see if your drive becomes accessible after each step. In my experience, you won't start seeing results until step 5 or so. 1. Run CHKDSK /R /P from the recovery console (it will typically find no error) 2. run FIXBOOT from recovery console (typically has no result) 3. run FIXMBR from recovery console (typically has no result) 4. Run the manufacturer's diagnostic utility, downloaded from their website (it will typically find no error) 5. Changing the drives from cable select to Master/Slave may fix it. 6. Replacing the data cable may fix it, but usually not. 7. Setting the BIOS to use defaults may fix it, but usually not. 8. Changing the BIOS drive settings from auto to user-specified, ensuring that LBA is selected may fix it. 9. Pulling the CMOS battery to let the BIOS lose it settings may work. At this point, you may be feeling some frustration. :-) If all that fails, here's what will usually work: Ghost your data to a new drive, and use the original one as a slave. It will work. And all

For example, having a partition that is about 20%-30% the size of the total hard disk allows short stroking, meaning that the number of reading head repositioning delays (a performance consuming process) is greatly reduced. However, though we can store different data on different partitions, certain partition might be inaccessible sometimes.
