Once I helped a family member who had no backup of a brand new, 4 week oldlaptop which would often blue-screen after a few minutes while beingextremely slow. Further troubleshooting revealed that the blue screens wererelated to disk issues. Running Spinrite on level 2(read everything and allowthe drive controller to mark sectors as bad, hopefully relocating the data)made all those problems to away. That laptop's drive continued to work fornearly 5 years until the laptop was replaced, even though I advised them toreplace the drive right away under warranty. I did of course set them up witha backup.

After Spinrite finished, I shut down the machine and rebooted into the regularlinux running on it. That has an encrypted disk, using dm-crypt and lvm, butwith trim enabled and the recent cloudflare additions to linux diskencryption to speed things up. Full disk encryption is rather slowwithout that and over time, not running trim reduces the speed even more,especially when the disk gets full. Running Spinrite also helps with(my perceived feeling of) increasing the snappiness of the machine.
SpinRite is not a defrag tool, but it is one of the best ways of keeping hard drives alive and working, and of recovering data from faulty drives.Supplier: Gibson Research CorporationPricing: $89.00 for personal use.Download: Purchase before downloading. Full refund offered if not completely satisfied. Purchase 4 copies for a site/company license ($356), 10 copies for a multi-site enterprise license ($890).Versions: 6.0 released June 7th, 2004. The first version was released in 1988.
Update: It is no longer necessary to use SpinRite for maintenance purposes on Windows machines: DiskFresh can do the maintenance part while Windows is running. See the separate DiskFresh review page. This is particularly useful since SpinRite took 330 hours (nearly 2 weeks) to do a full Level 4 scan of a healthy 2TB drive. During that time the entire machine was offline. In contrast, DiskFresh refreshed the same drive while it was in use in 22 hours.
Kickstart News review, published ugust 2004, updated January 2007: The opportunity for the first test appeared only one day after we received our copy of version 6. An 80GB hard drive on one of our busy storage servers decided to pack it in. Prior to trying SpinRite we were still able to access the drive intermittently but it was impossible to copy data or run a file undelete utility. A handful of important files had been written to the drive subsequent to the last backup the previous night; files which we needed within about 48 hours, which meant that a professional data recovery service (with its three week backlog) was out of the question. We removed the drive and installed it in an identical hardware configuration, then booted SpinRite 6 from CD and did a Level 2 recovery (see above for recovery level definitions). After 22 hours, SpinRite completed its work and pronounced the drive fully recovered. We reinstalled the drive in the original server. It ran perfectly, the research assistant who had created the required files copied them off the drive and that was that. Nice job SpinRite 6. The drive was still running fine as we went to publication with this review two weeks after the incident. We used a level 2 setting in SpinRite: Recover Unreadable Data.
When you first purchase and download SpinRite you are given the file SpinRite.exe to run which you can use to install locally or create an ISO to boot from. The easiest way to get the ISO is to run SpinRite.exe on any Windows system you have available, or even a Windows VM running on your Mac and copy the SpinRite.iso file across to your Mac. However if that simply is not possible for you an alternative way is to run SpinRite.exe in Wine on your Mac. I prefer the implementation provide by PlayOnMac so I will be using that in this guide. If you can create the ISO in Windows skip ahead to the next section.
Click Create ISO or IMG File and then Save a Boot Image File. When the folder structure appears select Users > your username > Desktop to save the SpinRite.iso file to the desktop on your Mac. Once that has been successfully created exit SpinRite and PlayOnMac.
Thank you for this report! I just purchased, downloaded, and installed SpinRite to perform a Level 1 scan of new drive before installing into my MacBook pro. Your tutorial worked exactly as you described.
Have you tried opening a second Terminal window and running the unmountdisk command again in that? Hopefully the problem is just what you think it is; that the disk has mounted again. If you try that before you boot the VM perhaps Spinrite will be able to see the partition.
Does spinrite need to be installed on the disk you are going to scan? Could I install it on a small USB flash drive and then run spinrite from that (after booting from an internal or cloned external HDD) and having done so, can I scan any of the connected drives?
On a non-fusion target I believe this should work fine with spinrite. But I failed here trying to create the RawDisk.vmdk, the command producing the error message VERR_RESOURCE_BUSY apparently because of the combined fusion drive arrangement. I tried the command on disk3 first and then disk5 (with some trepidation) but always got VERR_RESOURCE_BUSY.
The first step is to download and install VirtualBox. There is nothing special about the installation so just follow the wizard through without changing any of the options. You also need to transfer your copy of SpinRite to the new MacOS install (you need the ISO, read the first section in Part 1 of this series for details on getting that).
I bought and download the application and then was bit stumped on what to do next. The documentation on the website is dated so it took me a while to figure out how to get the software to run. I had an especially difficult time because the software was written before UEIF motherboards where common place and my mother board has UEIF enabled. So I documented my steps so I remember and hopefully it will help others as well.
for jack shack. thank you for your reply. Spinrite 6.0 from 2006 is the latest edition. I have used it for years from the late 1990's. the home machine is from HP and Spinrite works perfectly. Steve Gibson says it should work on any machine with any operating system, and i trust him. How is it possible to reconfigure from RAID On to RAID Autodetect/ATA? is this a bios download (if so, from where) or is there a switch on the motherboard? if i make the change, i probably would not want to change back to RAID On. You mention DOS being modified to recognize AHCI. is this necessary if the RAID switches are changed and how would one do this?
Clonezilla is one of the most useful free hard drive repair software tools. It allows you to easily create full partition and disk backups, which can be deployed on other computers. Clonezilla supports far more file systems than most IT professionals can name, and it even features some basic boot repair tools.
GParted is a free, graphical partition editor that you can use to resize, copy, and move partitions without data loss or file corruption. You may want to shrink a partition to create space for another operating system or a backup partition. GParted is part of many other hard disk tools, such as Clonezilla or Partclone. It can also be downloaded from the official website as a small bootable GNU/Linux distribution for x86 based computers and used from a USB flash drive.
Run the HP tool, pointing it at the directory where you unzipped the DOS boot files, and it will automatically build a bootable DOS USB drive using those files. Next, copy your original SPINRITE.EXE file onto the root directory of your USB drive. Once done, reboot the system with your BIOS configured to boot from USB drives. At the DOS prompt, type spinrite to start SpinRite. 2ff7e9595c
