Partition Table Corrupted on External USB drive
Hi
I have managed to corrupt the partition info on my USB HDD the HDD is 465GB and I was moving (silly me) data onto it. Went off to do stuff. Came back to check data and I can no longer access the drive. Windows explorer sulks and reports X:/ is not accessible. The parameter is incorrect Disk Management reports 2 partitions (there was only one) of 40Mb and 100MB and the rest (465GB) unallocated EaseUS partition recovery reports 2 partitions 465GB, 100 Mb and 465 GB unallocated This looks sensible (in that the original drive was 465GB) So how can I rebuild the original partition table and hopefully recover the data?

Partition table: Well its a 465Gb disk now showing 2 partitions of 465Gb and another of 100Mb so its hard to see what else it might be.
Ive tried EASUS partition recovery and it did nothing. Not too surprising since there were no lost partitions - just suspected corrupt partitions The data recovery tool identifies some of the lost files and is a start but still does not repair the partition table and the recommended solution (save what you find and re-partition the HDD) is likely to destroy any chance of recovering the rest. For a given HDD I wold expect the partition table to be 'standard' and am surprised there isn't software that will repair and existing table. |

It needs to be able to find the partition table backup.
You could try some other tools and see if they are any more successful. Minitool part recovery 5 is generally pretty good. Download MiniTool Partition Recovery 5.0 ![]() Or you can try diskgenius All-in-one Solution for Data Recovery, Partition Manager and Data Backup - DiskGenius Rt click the disk and select search lost partitions ( partition recovery is included in the free version , but data recovery requires a license. ) ![]() |

If you can't recover the partitions, then the free minitool data recovery 6 is worth a try.
PowerDataRecovery.zip.apk (it is a .zip file, take the .apk extension off the end) If minitool data recovery doesn't do the job, then one of the better paid data recovery programs is active file recovery - it is also half the price of most others. It will scan first, then if it finds what you want, you need a license to recover the stuff. [email protected] File Recovery is a tool for data recovery. LSoft Technologies |

Thx I'll give it a go.
But most of these seem to work at recovering a deleted partition not repairing an existing partition. I was playing with DiskInternals partition recovery and it all looks fine, identifies the partition informaiton on the disk but will only search for files as opposed to repair the partition table. Or is this not possible/practical? |

Are you sure it isn't damage to the filesystem?
Normally one would use checkdisk, but that might not work if explorer tells you it can't be accessed. You are probably best trying to recover whatever files you can. Then after you have done that, you could try deleting the partitions, followed by partition recovery. |

Done the recovery bit. Got some useful stuff but not much. I suspect most of it lies in the 465GB unallocated
So you reckon I should use a partition manager to delete the existing partitions and then try to recover them? Seems a bit Irish. If it works, it will get me back to where I am! I could delete them all and create 1 new one but that will surely screw everything up (if it isnt already!) |
