As to cost, there is a lower yield on parts coming out of the 'machine shop' and electroplating phases of production due to the tighter tolerances. The firmware also has to be more accurate. Faster wear from more rotations/time lessens time to out of spec tolerances. The tolerances are tighter for the head to hit the 'right spot' on the disc at a higher RPM so: They use higher quality parts/materials. The drive will not rearrange anything when mersenne twister, random, imaging or any other random data is written.įaster is more stressful on the mechanicals so for faster: The drive will fix bad sectors on any write but only zeroing improves the speed. The tools trying to fix one sector at a time can make the bad sector map so convoluted that the drive will give up. If there are too many errors then the operation will halt and you know the disk is bad. The drive will fix and remap all bad sectors including those that are in places the operating system never uses and at the end the drive sorts the bad sector list so the drive works faster. Writing zeros takes the same amount of time as reading the drive but is much more comprehensive. It's a bad technique if you're trying to validate a drive as fully functional. This is a good technique if you are trying to recover data and there's a bad sector interfering. All the software does is to read the whole disk and write zeros to any bad sector it finds. Just write a sector and the firmware does the rest. The firmware on the drive is where the magic happens and no special software is required to make it work. Error correction is not magic performed by the software. There's no reason the software can't run on other brand drives other than to annoy the user. Since there are only 8760 hours in a year isn't that 171 years? I still trust SCSI, median average failure time 1.5 million hours! What's your longevity record for consumer grade IDE and SATA drives. There were three or four newish drives with the "click of death", the heads refusing to park properly.įortunately there was a 750GB with less than 1000 hours, two 250GB drives with no faults, one Seagate 250GB with one error that I corrected, a working 160GB laptop SATA drive, and surprisingly a couple of those skinny Maxtor IDEs which had big hours but no faults. There were several newish drives with I guess bad logic boards as the drive was not detected at all. Some of the drives with unfixable media faults had hours as low as 1800. Most of the drives had POH hours between 500. Since WD and Samsung only evaluate defects, which Seatools does already, why bother?Īt any rate the POH (powered on hours) was very interesting to me. It evaluates any manufacturers drives, and allows error correction on Seagate (and Maxtors made by Seagate) drives. The best tool by far was Seagate's Seatools for DOS. I downloaded all the Drive Tools I could find from Seagate, Western Digital, Samsung, Hitachi and Maxtor. If your Seagate portable hard drive won’t show up, consider showing all hidden devices.I recently bought a box of 20 plus hard drives, a mixture of IDE and SATA. Your Seagate portable drive may not be showing up because of a faulty USB cable as well so you can replace the USB cable if changing the port doesn’t work. Try to plug the drive into a different USB port and see if it is recognized. Check the connections and try a different USB portĪ reason why your Seagate portable drive is not being recognized could be that you might have plugged it into a faulty or loose USB port. Seagate External Hard Drive Not Showing Up In Windows 10? Let’s Go Step-by-Step!Įvery step is good enough to solve this problem, so don't miss any of them! Step 1. These include outdated drivers, virus attack, etc. Hard drive failure may occur due to external factors like high magnetic fields, physical damage, water ingress, etc. It is the most common situation for a USB port to not work properly. If your Seagate external hard drive is not showing up in Windows 10, 8 or 7, the problem may be as simple as a USB port.
