This device SHOULD have been sold to you as a >4 GB device. The capacity this drive reports itself as having is accurate. The MBR (incl partition table) would probably add another 16K or soģ) Opting to perform a quick check, as opposed to using this utility’s more thorough option. This is pretty “normal” in the industry and done to make products sound better than they actually areĢ) Slight errors of a few KB in the testing process due to only checking the partition area of the drive selected. This is “normal”, and can be caused by several things:ġ) Manufacturers pretending that there are 1,000,000 bytes to the MB instead of 1,048,576. a 64MB drive may be reported here as only having 61MB of storage. Note: The *actual* capacity of the drive shown above may well be less than was claimed when it was sold to you as (e.g. This sounds a bit dodgy, though it’s not unheard of with some flash cards, and is less than twice the blocksize we’re using to test (1048576 bytes), so we’ll let it slip here… Verified max bytes writable: 33549189120 (31995 MB)Īble to write more data to the drive than we could successfully read back.

The interactive testdisk tool can scan for lost tables: testdisk. However, if as the case most often is, we don’t have a backup, there is still hope. Partition length : 33549713408 (31995 MB) sfdisk -d /dev/sda > parttable sfdisk /dev/sda < parttable While the first command dumps the table to parttable, the second restore it from that file. Media type : 0x0B (Removable media other than floppy.) I've now re-run TestDisk, aborted the Quick Search, and got to the option of Deep Search specifically, which is now running (I'll leave it running for the night).
