Rotational latency is incurred because the desired disk sector may not be directly under the head when data transfer is requested. Average rotational latency is shown in the table, based on the statistical relation that the average latency is one-half the rotational period.

Hard Disk Sentinel (HDSentinel) is a multi-OS SSD and HDD monitoring and analysis software. Its goal is to find, test, diagnose and repair hard disk drive problems, report and display SSD and HDD health, performance degradations and failures. Hard Disk Sentinel gives complete textual description, tips and displays/reports the most comprehensive information about the hard disks and solid state disks inside the computer and in external enclosures ( USB hard disks / e-SATA hard disks).

Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

Defragmentation is a procedure used to minimize delay in retrieving data by moving related items to physically proximate areas on the disk. [126] Some computer operating systems perform defragmentation automatically. Although automatic defragmentation is intended to reduce access delays, performance will be temporarily reduced while the procedure is in progress. [127] Have another drive or device ready. You have two options here. You could buy a new hard drive and install it in your current computer, which is ideal if your device is still fairly new, such as one or two years. For older devices, it may be time to consider a new computer.

Traditional SATA hard drives may have largely made way for much faster solid-state drives, but they're still very popular and remain an affordable way to store things like pictures, videos and other non-strenuous file types. SSDs work a little differently, and while they never need defragmentation (because fragmentation relates to where the data is physically stored on the drive, which isn't a factor on SSD), they do sometimes need optimizing.Albrecht, Thomas R.; Arora, Hitesh; Ayanoor-Vitikkate, Vipin; Beaujour, Jean-Marc; Bedau, Daniel; Berman, David; Bogdanov, Alexei L.; Chapuis, Yves-Andre; Cushen, Julia; Dobisz, Elizabeth E.; Doerk, Gregory; He Gao; Grobis, Michael; Gurney, Bruce; Hanson, Weldon; Hellwig, Olav; Hirano, Toshiki; Jubert, Pierre-Olivier; Kercher, Dan; Lille, Jeffrey; Zuwei Liu; Mate, C.

HDD price per byte decreased at the rate of 40% per year during 1988–1996, 51% per year during 1996–2003 and 34% per year during 2003–2010.

HDDs are being superseded by solid-state drives (SSDs) in markets where the higher speed (up to 7 gigabytes per second for M.2 (NGFF) NVMe drives [157] and 2.5 gigabytes per second for PCIe expansion card drives) [158]), ruggedness, and lower power of SSDs are more important than price, since the bit cost of SSDs is four to nine times higher than HDDs. [17] [16] As of 2016 [update], HDDs are reported to have a failure rate of 2–9% per year, while SSDs have fewer failures: 1–3% per year. [159] However, SSDs have more un-correctable data errors than HDDs. [159] a b Schroeder, Bianca; Lagisetty, Raghav; Merchant, Arif (February 22, 2016).
