Oh boy oh boy. Xebby has a new toy!
We recently got this wonderfully awesome super cool new thing from Ace Labs. Anyone guess what it is? PC3000 SAS/SCSI w/ RAID recovery and extraction. Oh boy! We have been having some trouble as of late with getting data from SCSI and SAS drives. Well, this new fancy tool lets us get the job done. Sometimes tempermental when you have a bad drive but isn't everything?
The first case to use this on? 2.5" 73GB 15K Seagate SAS drive with stuck heads. Yep... Stuck heads on a tiny little platters.
Okay dark alter ego. You can go back in your cage now.
So, how exactly does one unstick heads? There are a few ways. One involves tools (very expensive tools mind you) and the other involves using what you got. Well, you don't have tools for EVERY drive made so we got to do with what we have. What is the trick?
Bit hard to explain but here it goes:
You take the lid off the drive but leave the magnet and stops in place. Place your thumb right on top of the bearing of the heads and apply pressure. Then, you turn your thumb while maintaining some pressure counter clockwise. Next, you grab a screw driver and you bang on the top of the drive to get the heads to "jump" off the platters. Seems barbaric, unprofessional and scary but I trust you it works. The trick is to keep the head assembly steady with even pressure and apply even torque throughout the process. So far, my head recovery rate is approx 90% using this method. It takes time, practice and a little luck but works. The original heads still work and most of the time leaves no marks on the platters.
I perform the described method above, reassemble the drive and test it. What do you know, the damn thing still works. It starts making some strange sounds but nice thing with these kinds of drives is there ability to recalibrate. After about 10 minutes of it making various clicking, seeking and recal sounds it gets ready and I can access the drive via our new tool. Open the utility, create a task and bam, it images well but requires constant recalibration. With some tweaking it moves along at a nice steady clip. The only issue is toward the end of the drive there are bad blocks. No big deal. I checked over that area of the drive and there was no data except for the termination of the EFI table.
Amateurs need not apply here. A pro with the right tools, techniques and knowhow can and will find a way.
The cazy thing is that this job came in same day and left same day. Thankfully it was a tiny drive. Otherwise this could have gone on for a while... Maybe "gasp" required a head exchange. *shivers thinking of doing one on this drive*.
Now, dark alter ego, what do you have to say?Edited by Lord Xeb - 4/11/17 at 5:58pm
