Well, not until at the very least you can assess that the device truly has a damaged partition. Here's how!įirst rule about data recovery and fixing disk partitions is that you do NOT want to make any changes to the environment, the disk in question, the partition, etc.
#Photorec hfs file system free
Luckily, I used some recovery tools, both free and paid, to not only fix my partition, but to also get my data back onto another redundant networked attached storage array called a Synology Diskstation.
I could see the Drobo in my Disk Utility, but I could not see the 8 TB partition with my archived data. I recently had to restore some archived data that I had "responsibly" stored on a redundant storage backup device called a Drobo that unfortunately for me, decided to have an HFS+ filesystem partition failure. and I'm unable to convince said owner of the value of backing up data, even after events such as drive failures.Data loss sucks. The drive is not mine, and the backup that I do have was made without the owner's knowledge, consent, permission, etc. Basically, what I should do next, at this point.Īlso, in your advice, feel free to refrain from "Lesson learned, constantly back up ur stuff!" lectures.
#Photorec hfs file system how to
I'm looking for advice on how to either repair the disk so it can be mounted and all the data copied off, or perhaps another tool similar to photorec can be recommended, but one which can recover all files and folder structures. I have a backup of this drive from some time last year, but the backup has less than half of the amount of data that's actually stored on the drive currently. (I do not know what error is produced, if any)
#Photorec hfs file system software
I gave the drive to someone that has an iMac and he tried it's GUI disk utility software to fix the drive, to no avail. Likewise testdisk hangs during analysis when it gets to cylindar 74. I tried using hsfprescue which seems like the perfect tool for my problem, but during the analyze step ( hfsprescue -s1) it hangs at 0.06% just like ddrescue. I think a catalog must exist in order for it to be rebuilt or repaired.įsck.hfsplus -q reports a DIRTY FILESYSTEM. Seeing the Catalog file entry not found for extent error, which I also get when trying to preen, I decided to rebuild the catalog with -r, but no success. Total sectors for embedded volume = 0 0x00 Using cacheBlockSize=32K cacheTotalBlock=1024 cacheSize=32768K.Īlternate VHB is at block 1953458172 0x746f67fc I tried fsck.hfsplus -d and got these results, ** /dev/sdd1 However, I would like to recover everything (including an intact directory structure, preferably) and not just the files that were deleted before the drive began to fail. I then started photorec, which seems to be recovering deleted files from the partition just fine. I ran it for a day, and decided that 41 years of ddrescue is longer than the data will have value. To fully recover this 1TB, it had 41 years remaining.
At 0.06% of the recovery, it slows down to bytes/second scanned, and eventually sped up a little, but still seemed too slow for my liking. I tried gddrescue, but that was taking too long to finish. I'm using Linux to try to recover all the files, or to repair the disk and then mount it and retrieve everything. I have a 1TB External drive that was formatted HFS+ for use with a Macintosh Apple Computer.
