SMART Sector error reloaction/Seek sector errors
Both SMART values haven't deviated from being reset after a 5-hr. chkdsk /r /f. Some sort of numeric relative values, possibly endemic to Samsung's SMART implementation, at a base 100 designee for the seek errors, and 252 for reallocation counts;- fields repeated twice for comparative values presumably of severity. (Other fields would not permit a reset, without guarded manufacturer codes -- e.g. UDMA or CRC errors.) That was a couple weeks ago. Subsequent data to the HDD I'll continue to favor, subtractively, with a 1T SSD working now in conjunction over a database specifically the SSD absorbs as further data modification resume: Sets of data modification can be moved off the HDD drive and its prior SMART errors, to the SDD, with reasonable time and adequate storage the SSD provides. Of course the HDD has not, per se, been written to since the check disk routine, only copied from and to the SDD. A recommended course, for some at least, upon encountering the above errors, check disk at a sector level bubble-gum back together, (not necessarily in accounting the added writing precautionary measure I thought to add), while still able to and should deteriorating sector counts not again resume;- Along with a working back-up for another clear meaning deterioration is given to eminent failure with no forewarning. Also haven't noticed any glitches since in media playback. Not sure how old that particular 2T HDD unit, not having tracked down a serial nomenclature for a date of manufacture. I'd guess it's been largely dormant in a shelved back-up capacity for perhaps eight years. I installed it for 24/7 service maybe six months ago with really no concern or special note for probable SMART errors then present;- not until, that is, the glitches more of late began to occur, potentially capable of gumming-up drive retrieval if not an "organic aspect" of the whole SATA-controller and system driver device chain. |

Prior and at some point over a course of the last two or three motherboard updates, I began to notice decided lags during defragmentation. An earlier SATA hardware controller implementation, both on motherboard controllers and PCI HDD controllers, were straight-forward, progressively visible manifestations within if not nearer to copy/write, at expected speeds. That particular motherboard had but two SATA ports (and a PCI SATA controller for a sum four SATA connections). I haven't longer the indulgence of PCI slots in a present stasis of, usually one slot, budget micro-motherboard factors;- nor are added controllers necessarily the budget price consideration of under $10US controllers before. Indulgence, however, is neither being constrained by a single HDD, more frequently for modified files to occur to subsequently defrag, since alternatives since include a supplemental larger SSD to move instances of modification from the HDD and to the SSD. Although it not is not quite the indulgence, at times and within deframentation approaches, similar but exacted, up to extended file copies, if needed across the whole of a drive, that result in alphabetical file orderings (within a greater result, per se without fragmentation, resulting of non-fragmented files from a file copy/write routine). The software defragmentation routines, however, are not now buffered as smoothly as former PCI controllers. Timing is resultantly extended, whereas actual copy/write manipulations, which would not exhibit speed deterioration, is the preferable recourse to, without exception, to say copying near 2T of data, in hours, versus similarly defragmenting that structure over an incredulous course of actual days. A given limitation, as it is, that deframentation so engaged is to be within limited fewer instances, which do result from files defragmented, upon copy/writing them, such to only run defragmentation on those specific files, with disdain for other than the perfunctory result of singular unity. Any larger degree of fragmentation, apart of altogether being avoided, (a HDD stasis and the supplemental SSD augments to circumvent), would be addressed by a re-copy, possibly with a initial format of the drive, only customarily to address what few files do fragment during the copy, and, in the case of the SMART errors perhaps specific to questionable drive media mentioned before, such that a low-level ChkDsk routine is then successfully run, hopefully to reestablish continued stasis for stability across long-term database reads. A ChkDisk capable of going beyond to address sectors differentially by time would be interesting if it existed. One further yet is the implication of extended framgmentation manipulation of so-addressed routines as desirable, indeed if not deleteriously to factor from newer instances of implemented controllers, indeed to precipitate not all may fail so abjectly, which strangely do not fault into "churning" episodes, as wholly do all deframentators I have -- wholly, that is, absent from all instances of programs which but copy and write. A deframenter to be suspect of added usage for prematurely wearing down drives with excessive churning may seem a damning indictment. But is it. . .HDDs no longer have a sole impetus upon storage from a shift, from ten years ago, as NAND SSD storage is seen in its two implementations, past SATA, as directly accountable for motherboard implementation of storage much as slotted memory. Strange as it may seem, I've actually seen instances for future design implementation, abnegating the SATA factor, altogether a PATA interim patchwork, much as was ISA superfluously rendered obsolete by PCI. |
