![]() ![]() It’s like the drive is fine, but thinks there’s nothing there. I’ve had drives which have suffered complete hard crashes because of power loss while doing writes to the disk, and never seen anything like this. Other footage was GoPro, BlackMagic, and Canon wrapped H264s. Have tried creating custom file types to identify video files, but no luck I’m not sure I know of any software which recognizes AVCHD / MTS Program Streams. StellarPhoenix identifies these as “Recovery” volumes, but does not locate anything other than these three. Does not show any volumes for me to rebuild.įileSalvage locates 40 files on what appears to be the WD SmartWare volume (I opened some and found the standard PDF documents, etc), and appears to identify two other volumes of about 620mb, but does not find files or allow me to repair and rebuild a volume. Techtool Pro 7.0.5 does not find any bad sectors. Has anyone else had this problem? Is this a problem that is localized to WD drives? I am more familiar with G Technology, Lacie, and Glyph drives, so I’m treading in new territory here. With hundreds of drives over the past decade plus, I’ve never lost a drive due to failure to properly eject, only from known issues like age, physical failure, etc… Additionally, unless this occurred during a write operation to the disk, I can’t imagine it happening. Unlikely for the drive to ever have been removed without being properly ejected, so while the symptoms do appear to be those of corruption, not sure how or why that would have happened. Others in this thread appear to have had similar problems: ![]() This is one drive of a set which are being used for this purpose, so the issue appears localized to this specific drive. Other identical model drives work fine using the same cable, and on these same computers. Issue is under OS X 10.9.4 on custom built computers and Macbook Pros. There is no physical damage to the drive. ![]() It passes SMART, Quick Drive Test, and Complete Drive Tests in WD Drive Utilities.ĭoes not appear at all under DiskWarrior 4.4, though other disks do.ĭrive was last used to copy a significant amount of footage from an Avid Media Composer project, as well as to store MP4 and other various video formats, raw camera and audio dumps. This was a transfer drive from a company and they deleted the files before I had backed them up, so I unfortunately do not know exact file types, file structure, etc… Making it unlikley for basic data recovery software to be able to detect the filetypes (ie an Avid MXF). Of course, the problem could still lie elsewhere.It appears as a blank drive with no partitions in disk utility. Surface Scan test – scan in progress SMART check – results If failures are found with either of these tests, then the disk is physically damaged, and will need to be replaced. In this case, either the SMART check or the Surface Scan test can identify hardware problems with the disk. If the volume structures test doesn’t find any problems, but you’re still thinking it’s a disk problem, then it might be the hardware of the disk itself. Checking Volume Structures Volume Rebuild Tool – Disk repair in progress Physical disk damage The Volume Structures test in Techtool Pro can be used to identify this damage, while the Volume Rebuild tool can be used to repair it. Volume Structures damage (or directory damage for recovering Windows users) refers to the data stored on a disk that keeps track of your photos, movies, music, and other files on the disk. If you suspect a hard drive problem, it will be one of two things: 1) Volume Structures damage or 2) Physical disk damage. Slow performance, sudden application crashes, even computer crashes can be attributed to a malfunctioning hard drive. Both solid state and rotational hard drives can be the most error-prone components in your Mac. If your Mac is running slowly, crashing, or just generally misbehaving, the problem may be your disk. ![]()
