I have a external drive that is formatted as exFAT. It does not show up on my system when I plug it in. When I run Disk Utility, the drive appears on my system but I get the following message:
Updating boot support partitions for the volume as required.
Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
I then ran fsck_exfat
in a terminal and got the following:
sudo fsck_exfat /dev/disk2s1
Password:
fsck_exfat: Opened /dev/rdisk2s1 read-only
** Checking volume.
** Checking main boot region.
** Checking system files.
** Volume name is 2tb_WD.
** Checking upper case translation table.
** Checking file system hierarchy.
fsck_exfat: Couldn't read 131072 bytes at offset 302667137024: Input/output error
How can I recover the data on the external hard drive?
1Use data recovery tools. What is the actual question? – STTR – 2013-06-26T17:28:49.277
Well Disk Warrior will not read the disk, what to you suggest? I was hoping fsk would repair the drive. – user233970 – 2013-06-26T22:05:06.850

Remember to properly format your question. Use a right angle bracket
>
before each line of a blockquote, and indent code blocks with four spaces. – bwDraco – 2013-06-27T01:23:00.8831
An input/output error most likely indicates bad sectors on the hard disk.
