<\/span>How to Identify and Properly Address Corrupted Hard Disk Issues<\/span><\/h2>\r\nBefore we start, it should be noted that in any instance where your drive has suffered data loss (this includes existing data that has become inaccessible), recovering your data<\/a> is the first priority. Why? Because any action taken on the drive, including fixes, has a risk of making the data permanently unrecoverable. So, if you value the data on the drive<\/b>, recover it first<\/b> and then fix the drive<\/b>.<\/p>\r\nDuring our research on this issue, we found a myriad of causes behind it. However, there were some that cropped up more than others. We put together this list, and article as a whole, with corrupted internal hard drives in mind, as we already have a guide for repairing corrupted external hard drives<\/a>, along with one for fixing corrupted hard drives on Macs<\/a>. However, most of these problems, and their respective recovery methods, apply just as well to external drives.<\/div>\r\n\r\n❗️ Here are some of the most common scenarios, along with our recommendation of what to do in each case:<\/b><\/p>\r\n\r\n\t- The file or directory is corrupted and unreadable.<\/b> Often displayed when trying to open, copy, or move specific files or folders due to file system corruption<\/span>1<\/sup><\/a><\/span>, and is also presented as Error 1392<\/span>2<\/sup><\/a><\/span>. Recover the data<\/a> first, then run CHKDSK to repair file system errors. If the affected files are on the system drive, use SFC and DISM to repair damaged Windows files.<\/li>\r\n\t
- The partition has converted to RAW, and Windows wants to format.<\/b> Another indication of file system corruption. Windows reads it as RAW because it cannot detect a working file system. Recover the data<\/a> with data recovery software, then restore the partition with TestDisk or format the drive with a new, healthy file system.<\/li>\r\n\t
- The drive appears as \u201cUnknown, Not Initialized\u201d with 0 bytes in Disk Management.<\/b> This means Windows cannot read the drive\u2019s reported capacity, usually due to a hardware or connection issue. Check the cable, port, or system first. If the drive is then detected correctly but still inaccessible, it may be partition table corruption<\/span>3<\/sup><\/a><\/span>. Recover the data<\/a> with a data recovery tool capable of reconstructing the layout or file-signature carving<\/span>4<\/sup><\/a><\/span>, then initialize the disk, choose a partition style, and then format it.<\/li>\r\n\t
- The drive is displaying CRC errors.<\/b> Cyclic Redundancy Check (CRC) errors occur when data read from a drive doesn\u2019t match what was expected. They can be triggered by faulty SATA\/USB cables, ports, or enclosures, so you should start there. If they persist, it can indicate bad sectors or physical degradation of the drive. In this case, you should create a byte-to-byte image<\/a> of the disk for later recovery, or consult a data recovery service<\/a>.<\/li>\r\n\t
- The message \u201cThe parameter is incorrect.\u201d appears.<\/b> The drive may appear in File Explorer with a drive letter, but any access attempts are blocked behind \u201cThe parameter is incorrect\u201d, and CHKDSK may mislabel the drive as RAW. This is often a hardware or connection issue, but it can also be software-related. Confirm the connection is secure, and if the problem persists, repair the partition with TestDisk, or recover the data<\/a> and format the drive.<\/li>\r\n\t
- The disk is reporting the incorrect capacity.<\/b> This could be the result of partition table corruption, or worse, physically damaged sectors or hardware failure. Backing up the drive and recovering the data should be done immediately. In cases where this is obviously linked to physical damage, reach out to a data recovery service<\/a>.<\/li>\r\n<\/ul>\r\n
The next section will guide you through backing up the drive and recovering its data.<\/p>\r\n
<\/span>Recover Data Before You Fix a Corrupted Hard Drive<\/span><\/h2>\r\nIn any instance where your data is lost or deleted, your first step is to either recover the data or back it up to prevent further loss. Any attempts at fixing the drive can result in the data being lost permanently. Hard drive recovery software<\/a> can recover or back up the data even if it\u2019s deleted or inaccessible due to errors. Even if you suspect it was a physical issue and plan to consult a professional, it\u2019s free to download the software, scan the drive, and see what it can pull up<\/b>. We\u2019ll demonstrate what recovery looks like with Disk Drill<\/b>.<\/p>\r\n\r\n\t- Download<\/a>, install, and open Disk Drill. If your system drive was corrupted, you\u2019ll need to work from another PC, connecting the corrupted system drive to that system. \r\n \r\n \r\n \r\n
