yes. your hard drive has either been locked or is dying.
symptoms of this include applications struggling to load, strange sounds which you haven't heard before. irratic booting, etc. this is a dead hard disk. please could you drop me an email off list with details of your machine, if you have apple care cover, etc and I can walk you through various test steps, etc to identify a dead drive. from what you have described, your drive has failed. Hard drives have a shelf life, because of their rotational speed, heat, data read and write processes, drives fail. When they do, you know about it. I've been there only yesterday with an SCSI drive which failed, had to disassemble it, clean, respin and reassemble it to bring it back to life to back up the contents to install on a nwer drive. lew On 4 Dec 2011, at 21:30, Roger Woolgrove wrote: > Hi all, > > After installing some software and returning to desktop, MacbookHD is dimmed > and I seem unable to access it.
