The 137 is the way hard drive manufacturers calculate the conversion from bytes to Gigabytes. On the Internet you will find references to 127, 128 or 137 GB. This is the maximum Windows 98 supports for a bootable hard drive. Each sector holds 512 bytes and therefore the maximum capacity is 137438953472 bytes. If you see this and the drive is still in warranty, ask Samsung to replace it.The 28 bit LBA supports 2^28 sectors which works out to 268435456 sectors. However, I would view a pattern of repeated and typically escalating failures over time as a sign of impending drive death. A bad sector or three is more or less expected these days and is not in and of itself a reason to stop using a drive. attributes to see if the drive continues to degrade over time. Beyond that I would suggest continuing to monitor the S.M.A.R.T. It certainly is always a good practice to ensure you have a backup of your data. How "safe" would it be to continue to use this drive? Who knows? That might be what you want to try to do if the drive's Pending Sector Count remains non-zero. As an alternative, you could use a disk erase tool which wrote zeros to every sector on the drive. If that is true then a "format" would only be of use if each sector was written to not just read from. (See the description in the table for ID 197 (0xC5) Current Pending Sector Count.) The rational behind this suggestion may be to attempt to "force" the drive to remap a sector which so far has only failed when read. All you could do is a file system level format of (a partition on) the drive. That term hasn't really had any meaning for a hard drive for at least a decade or two now. What "hard drive check utility" did you use? Did it provide any other information other than the recommendation to format the drive?įor what it's worth, there really is no such thing these days as a "low level format" of a hard drive. You can refer to this table for a description of an attribute. Note: Your drive may not implement all of these attributes. ID 198 (0xC6) Uncorrectable Sector Count.ID 197 (0xC5) Current Pending Sector Count.ID 005 (0x05) Reallocated Sectors Count.In particular, see what the values of the following S.M.A.R.T. If not, there are freeware utilities available that will do this for you. Perhaps the Samsung diagnostic can do this for you. Next I would recommend that you look at the S.M.A.R.T. The first thing to do in a situation like this is to save your data, which you've done. The bad sector may have only been discovered because the Samsung diagnostic tool you used performed a complete scan of all sectors on the drive. If you were able to copy all the data on this drive and no errors were reported it seems quite possible that the offending sector was not even being used (yet) by your file system. For a while now the firmware in hard drives has been transparently handling sector write errors by remapping the sector to another location on the drive. Unless your hard drive is very old, the file system of your OS probably didn't even know anything had happened. In this case I assume it is just another, possibly more technically accurate way of referring to a " bad sector". LBA is an acronym for Logical Block Addressing. Well, that, and perhaps wave our hands wildly in the air for emphasis. Without knowing the details of your situation all we can really do is speculate. If you provided more information both about the model of drive you are using as well as about the errors the Samsung utility reported you might get better answers. Does that mean that I can safely use the disk after a low level format & it won't have any issues? The Hard drive check utility had suggested that I format the Hard drive.
