Q: I have problems with Disk1: I/O error, and com.apple.xpc...Can anyone help me plz?
Hi,
Problem: when I put my computer to sleep, upon waking it, there is a noticeable lag in performance. Internet is slow to reconnect, and GUI is unresponsive. This happens for around 10-15 seconds, and then things come back to life.
What I tried:
I opened console, and I copied the report. I found a few warnings, of which, I post a few (out of order).
host kernel[0]: CoreStorageGroup::completeIORequest - error 0xe00002ca detected for LVG "Macintosh HD" (4F6A789B-E1E1-458F-908A-844CDFA246CB), pv 31458C06-C725-4647-A817-A8C8461D59A2, near LV byte offset = 242813976576.

I also restarted in safe mode. The problem persists in the log.
I created a copy of the log open restarting computer in regular boot mode, and in safe boot mode. Then, I created three text files containing - log messages only in regular boot mode, log messages in safe boot mode, and log messages in BOTH.
Log Messages that appear only in regular boot

Log Messages that appear in both SAFE and Regular boot

Can anyone help me? Should I be thinking about buying a new HD?
Also noticed - when I have headphones or anything plugged into the phone jacks, iTunes spontaneously opens. Also, in the log messages
Thanks!!
