I'm getting disk errors on the same partition that failed last month:

 

 

May  9 09:44:08 office kernel[0]: disk0s3: I/O error.

May  9 09:45:52 office kernel[0]: disk0s3: I/O error.

May  9 09:49:54: --- last message repeated 1 time ---

May  9 09:49:54 office kernel[0]: decmpfs.c:1354:decmpfs_read_compressed: cluster_copy_upl_data err 14

May  9 09:49:54 office kernel[0]: decmpfs.c:1377:decmpfs_read_compressed: err 14

May  9 09:51:01: --- last message repeated 1 time ---

May  9 09:51:01 office kernel[0]: disk0s3: I/O error.

May  9 09:51:31: --- last message repeated 2 times ---

 

 

I ran Disk Utility from both a 10.6 installation disk and from my internal hard drive.  I ran it several times and both sources report that there are no problems with the disk.  So much for Apple's utilities.  SMART Reporter 3 alerted me to these disk errors.

 

 

Time for a new drive?

 

 

I have a 27" iMac.  Official specs:

 

 

  http://support.apple.com/kb/SP588

 

 

System Profiler says my current drive is a Seagate Barracuda 7200.12 ST31000528AS 1TB 7200 RPM 32MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive

 

 

  Capacity:          1 TB (1,000,204,886,016 bytes)

  Model:          ST31000528AS                           

  Revision:          AP25   

  Serial Number:                      9VP7S5TW

  Native Command Queuing:          Yes

  Queue Depth:          32

  Removable Media:          No

  Detachable Drive:          No

  BSD Name:          disk0

  Rotational Rate:          7200

  Medium Type:          Rotational

  Partition Map Type:          GPT (GUID Partition Table)

  S.M.A.R.T. status:          Verified

 

 

Again, according to System Profiler, apparently my chip set doesn't support the new 6 gigabit speed:

 

 

  Vendor:          Intel

  Product:          5 Series Chipset

  Link Speed:          3 Gigabit

  Negotiated Link Speed:          3 Gigabit

  Description:          AHCI Version 1.30 Supported

 

 

I tend to get Seagate Barracuda drives but am open to alternatives.

 

 

Here are my questions:

 

 

1. Are there heat or other considerations that I should take into consideration when replacing this drive?

 

 

2. Is it worth paying for Seagate's "Enterprise" drives? 

 

 

3. Any reason I shouldn't bump the capacity from 1TB to 2 or 3TB?

 

 

4. Any reason I shouldn't do the drive installation myself?  (The iMac is already out of warranty.)

 

 

Thank you for your help!
