[QUOTE="catfish32819, post: 1336487, member: 226964"] Below is a diagnostic from a third party data retrieval company. I think their quote - $1927 - is outrageous. Any ideas as to what I should do next. Can I send my iMac to Apple? Corey at the genius bar told me that my iMac is under warranty and there won't be a charge for a new hard drive. Visual Media Inspection There are no signs of external physical damage. Electrical Analysis The PCB board has passed all preliminary tests. Pre amp chip is fully functional. Internal Inspection The media has suffered from a head crash. Read/Write Head Test The read and write test concluded that the head stack needs repair. Spindle Motor Test Motor has passed all tests and is spinning at the intended specified RPM. Firmware/Logical LBA Analysis Logical test is inconclusive due to failed head stack. Conclusion/Solution: As mentioned, the HDD has suffered from a failed head stack assembly. Data recovery may be possible but obviously cannot be guaranteed until the retrieval process is finished and we have a file directory tree available for verification. We must manually repair the drive, and replace the head stack, only in the worst case scenario we will perform a platter transplant. Once we have repaired all mechanical issues, we will work with fixing the service area damage & bad sectors and using our industry leading extractor tools, we will clone your drive into an image, and retrieve your data manually. Once the retrieval process is completed, we will attempt to retrieve the original file table to preserve the integrity of the data. [/QUOTE]
