![]() ![]() In a first pass it’ll read everything it can and keep a log of any sectors it couldn’t. If you can boot into Linux of any flavour then ddrescue will clone your hard disc to another. However, Spinrite costs $89, but you get a lifetime personal licence and a money back guarantee if it disappoints. If it was a transient error from a physical jolt or a voltage spike during a write and the disk is otherwise in good health, you can continue using it. It’s far more persistent than any OS or the drive’s internal error recovery logic. Spinrite can often recover unreadable sectors by doing its own error correction on the aggregate data accumulated from many reads. Unless you can boot your iMac into Linux and DOS utilities (I don’t know whether that’s possible) you’ll need to take out the hard disk and temporarily attach it to a PC. Take a look at Advanced Hard Disk Tools in the Restarters Wiki. File system repair utilities are of limited use in such cases. It sounds like you’re disk has got physical surface defects.

There are 3-4 different cables for 2009, 2010, 2011, 2012 macbooks so get the right one. Fortunately it is easily purchasable for $10-25 on Amazon (as of 2021) and was pretty easy to install with only a small philips screw driver. Tape is not meant to hold the cable in place, it acts as a comfy bed for the cable.Īpple later made a thicker cable with a diferrent model number to address this issue. The electrical tape backing is quite a slippery and smooth rubber surface. In the future, place electrical tape on the rough aluminum to reduce abrasion. The cable is the weakest link since it is sandwiched between your hot HDD/SSD and the rough brushed aluminium macbook. This cable's copper is fractured and transmitting data incorrectly making your Mac believe that it cannot find the boot HDD or SSD. The problem was the internal thin black flexible cable (less than 1 mm thick) that connects the drive to your Mac's motherboard. I thought my 8 year old OCZ Vertex 4 SSD was the culprit since my 10 year old Vertex 2 died in a Toshiba laptop. My Mid-2012 Macbook Pro 13" randomly stopped working due to this issue. ![]()
