I have been using Spinrite for a long time to help fix errors on hard drives, recover files from dead drives, and refresh drives that were unusable before. But Spinrite only work on drives up to 1TB (depending on cluster size). I am looking for some software that does the same sort of stuff as Spinrite does but on much larger drives (1+ TB).

(I have a drive that is 2TB and has started clicking and I want to recover the lost files, but Spinrite errors out because it can't index the entire drive.)

    Do you know that a new version is coming up? Steve temporarily stopped working on SR 6.1 to focus on SQRL (grc.com/sqrl/sqrl.htm), but he should be back on it (I'm lagging behind listening to Security Now, so I can't confirm 'is back')

  • @JanDoggen I knew he was working on the next version, but I'm guessing that it won't come out for another year or so and the drive I have won't last that long.

    HDD Regenerator (dposoft.net/hdd.html, hddregenerator.net) claims to also "repair bad sectors (magnetic errors) on a hard disk surface" and "4K sector size support", but I don't know what disk sizes that translates too.

    Would you mind adding some more details concerning your exact requirements etc? For someone not knowing Spinrite, you might be looking for a Solaris utility for a RAID system :) As a helper/guide, you might want to take a look at What is required for a question to contain "enough information"?

Then you really should use data recovery programs, like gddrescue combined with partition/filesystem recovery programs or data carvers (testdisk/photorec).

SpinRite isn't made to just recover data from a worsening (clicking) drive, according to Steve's video it reads, flips bits, writes, reads, flips bits back & writes data again, that should "refresh" the data. It does read & move difficult to read/bad sectors, but it writes them back onto the drive, not something you want to do with a failing drive.

If your drive is clicking and probably about to fail completely or crash, you really want to copy the data onto a good drive now. After you have a backup, then maybe you can milk some more use out of the failing drive
