A few weeks ago I decided triple my space and increase the RPMs of my hard drive and settled with a 750GB Seagate Momentus 7200RPM 2.5" SATA HD 16MB Cache.  I recieved the drive, Carbon Copy Cloned from the original, installed it and noticed lagging on tasks that never had caused any issues before (ie. opening a new tab, opening iTunes, using track pad commands between windows, etc.) in addition to glitchy graphics (text next to Apple logo & volume indicator) and system crashes (while using iTunes & Ableton Live -- hard disk overload light came on multiple times).  I troubleshooted with OWC's tech support, but wasn't able to come to a conclusion as to what was causing the issues (using disk utility, selecting startup disk, PRAM resets, Rember [to make sure my RAM wasn't shot] etc.). I had another identical Seagate HD set to me thinking it may have been a bad drive, only to find the same problems.  After troubleshooting more with OWC, I wasn't able to figure out the issue.  I thought it was my computer or maybe the SATA connecor so I put my stock 250GB HD back in and the computer worked perfectly again.  I took the computer to the Apple store and their diagnostics all pointed to healthy software and hardware.  I decided it may have been an extremely unlikely coincidence of two bad drives or a compatibility issue of the specific model of drive so I returned the Seagates for a 750GB WD Scorpio Black 7200RPM 2.5" SATA HD 16MB Cache.  After installing this, I immediately started experiencing the same problems.  Has anyone else experienced similar problems?  Any tests I should run?  Or are these hard drives not compatible with my specific computer for some reason?

    I've hear many positives with the Seagate and some disasters with WD - but your's seems as if it doesn't matter what the drive is. Even though your old drive is working fine, you might have a bad SATA cable. I would call OWC and order a new one just to rule that out as the possible culprit.

     

    Good luck,

    Did you attempt a secure erase? If so, that's what may be taking so long...

     

    I'm not sure where that leaves you now, either. I've never had a bad clone using CCC - but there's always a first time.

     

    You may want, at this point, just to take the computer with the newest hard drive into you local Apple Store and have them run diagnostics on the unit. It's worth trying, anyway, if you've no joy with a simple clone and restore.

    Thanks for the response Clinton.

     

    Based off of what tech support said at OWC, if it was the SATA connector, the drive wouldn't boot at all (or in other words: it would either work or not work, but not half-work/be slow). 

     

     

    That is completely false. There have been many reports of system problems that are related to a failing drive cable.

    Reports of system booting then crashing and overall slowness along with other problems.

    Replacing the cable has fixed most if not all of those problems.

    Recently there was a long thread on Seagate 750GB XT series drives failing. It turned out to be the cable and not the drives. When the cable was replaced the problems stopped.

     

    So Replace your drive cable. This is a known weak point in the MBP design.

    Shootist is right - that's why I suggested replacing the cable. It can work fine with one drive and cause problems with others. And if a new SATA cable works, it's a cheap solution.

     

    Good luck,
