Disk Utility - does Verify disk erase all data
Hi there,
My WD 500gb external drive is playing up. I ran Repair Disk in Disk Utility and received this message:
Verify and Repair volume “My Passport”
Checking Journaled HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Incorrect number of thread records
Checking multi-linked files.
Incorrect number of file hard links
Checking Catalog hierarchy.
Checking Extended Attributes file.
Incorrect number of Extended Attributes
(It should be 1111057 instead of 1111053)
Incorrect number of Access Control Lists
(It should be 1109337 instead of 1109333)
Checking multi-linked directories.
Checking volume bitmap.
Volume Bit Map needs minor repair
Checking volume information.
Invalid volume free block count
(It should be 6221426 instead of 6221246)
Repairing volume.
Next ID in a hard link chain is incorrect (id = 3618881)
(It should be 1251745 instead of 3610665)
Three questions:
1) What could have caused this? (the drive hasn't suffered any physical damange)
2) How do I fix it?
3) Does running Verify Disk erase all data on the disk?
Any advice/help is very much appreciated.
Cheers 🙂
