Bad sectors accumulating
Laptop drive's demise. Lockups that reset; files open on the second try; copies fail at the same point. Yet still readable. That is the time frame of concern.
Most common
Toshiba is one of the largest suppliers of 2.5-inch drives to laptop manufacturers, and therefore a great many users did not have a choice when selecting the drive. This greatly influences how failures occur and become apparent.
Repair shops get evaluated based on whether they can get a laptop booting again after fixing its broken parts. In many cases, that means replacing the original drive with a new one. Labs focused on recovering lost data also judge themselves against what they recover. On a failing disk, the two are independent tasks that need to be performed in a specific order.
Context that explains virtually every aspect of these types of jobs.
Toshiba absorbed Fujitsu's drive manufacturing business and produces in high volumes for OEMs. Therefore, Toshiba 2.5-inch drives end up inside laptops from a wide range of manufacturers. So while the customer may purchase the laptop itself, the drive inside has been selected through a process they've had no involvement in.
Why? Well 2.5-inch disks in portable devices experience harder conditions than desktops. In portable environments, they travel while powered; have their lid shut and then physically moved, prior to disk park completing; operate warmer as well due to poor ventilation within the confines of thinner chassis; and can be hit/knocked, an occurrence unlikely for most desktops. Thus, when we receive Toshiba failures, the majority relate to either wear/impact failure, versus the manufacture defect.
Additionally, the age of the drive may exceed what the owner believes. It could be the original drive installed into a system purchased several years ago, silently acquiring reallocated sectors no one has ever reviewed.

Hit/dropped while operational. Typically delayed — after the physical shock, the computer continues operating normally. Therefore, the user continues using it. Meanwhile, a misaligned read/write head intermittently contacts the media.
The drive spins normally, but reports zero capacity or a blank model. The drive cannot describe itself and the data is untouched. This option is accessed by using the diagnostic interface without having opened the case.
Drive does not spin at all; may have a burnt smell. One of the most positive aspects of a board failure is that the board is designed to fail first, so the platters remain unaffected.
Typically where the time frame used to complete a Toshiba job originates.
A mechanical recovery requires a donor with matching characteristics far beyond capacity. A donor's head configuration must match, firmware revisions must be compatible, and the drive family and manufacture location are also important factors. Two drives with the same model designation but different firmware revisions could potentially be completely incompatible as donors.
For most common laptop models, this is a relatively easy task. However, for OEM-specific drive variants supplied to a single manufacturer, or for older units, it can take days to source the right match. This is typically the slowest portion of a Toshiba job and impacts the time frame as opposed to the ability to complete the job.
Modern board level jobs have similar requirements but in a slightly different format. The reason is that many modern drives will retain adaptive calibration that is stored in a ROM chip and is unique to each individual unit. Therefore, if you are using a donor board you will need to transplant the original chip over to the new board.
Identifying exactly which model the drive was when viewing a photo of the drive label helps speed up the process of determining what family and firmware version of the drive was used. As such, a photo of the drive label does help identify compatible donors.
If your Toshiba laptop drive continues to boot, but shows freezes and takes forever to open files, then your drive is still readable. At some point in the future, that window will close. That window represents one of the least expensive recoveries available and it closes without warning.
The longer you run the drive when there is mechanical failure, the worse it will be. Shut down before trying to make just one more copy. Single drives in Manchester are from £300 +VAT after a free 48-hour diagnostic.
These units are no better or worse than their counterparts. We find them frequently in recoveries simply due to Toshiba's supply chain; they provide hard disk drives to laptop manufacturers in volume — so, therefore, a great many people will get one that they did not pick out and most laptops run harder than most desktops do.
In most cases these are collecting bad sectors. When the drive attempts to read a sector it cannot read, it keeps retrying until the operating system freezes waiting. The operating system seems to "freeze" but it normally resolves on its own. The drive is still readable. Copy those files off immediately.
Most likely the problem is with the firmware rather than the physical mechanism. Drives retrieve operating code from a reserved service area on the platters and if a part of that area fails to read, the drive cannot report itself — although all of the data exists right behind it.
Because compatibility requires matching in head configuration, firmware revision and drive family, not only capacity. Drives from the same model number but different revisions can be incompatible. Also, OEM specific models are difficult to locate.
Yes, and this happens frequently. The drive is removed from the laptop. It is then tested using independent testing equipment. Therefore, whether you have a dead screen, board or keyboard does not affect whether your data will be recovered. Most times if your laptop has died it is an inconvenient situation, and rarely will it result in lost data.
