Have you run into a situation where you try to access your USB hard drive and get the following error:<\/p>\n
E: is not accessible. The parameter is incorrect.<\/strong><\/p>\n
where E: is the drive letter of your external USB hard disk.<\/em><\/p><\/blockquote>\n
You may also get the access is denied error. The drive remains inaccessible even if you try to hook it up to other computers.<\/p>\n
A friend of mine ran into this situation and got a quote of $500-$800 from various local data recovery companies in the Seattle area. When she brought the 3.5″ external 320 GB Seagate USB drive to me as a last ditch effort before coughing up hundreds of dollars, the first thing I did was connect to my Windows 7 computer to see what kind of error I would get. I was able to see the drive but got the Access is denied<\/em> error. I decided to use the CHKDSK utility. I figured if that didn’t work then I will look into using some software that can possibly repair the drive because I assumed there were lost clusters, or other disk errors that were making the drive unreadable.<\/p>\n
I ran CHKDSK G: \/F \/R \/X, where G: was the drive letter for the USB external drive on my computer.<\/p>\n
\/F fixes the error on the disk<\/p>\n
\/R Locates bad sectors and recovers readable information<\/p>\n
\/X Forces the volume to dismount if necessary<\/p>\n
You could also run CHKDSK without the \/F parameter to see if there are corrupted files before fixing them. Then you can run CHKDSK with \/F parameter to actually fix the lost clusters, along with \/R parameter to locate the bad sector and recover readable information from the hard disk.<\/p>\n
It took several hours but luckily CHKDSK found about 1.6 GB of data in over 5000 recovered files. I let CHKDSK convert the lost chains to files , fix cross-linked files by copying them to other locations, and rename the duplicate files in the folders. I was able to recover almost all of the data (about 50 GB, with over 40,000 files), except for 8 files. I reformatted the drive with NTFS, which is much more reliable and secure file system than the original FAT32.<\/p>\n","protected":false},"excerpt":{"rendered":"
