Subj : What to do with a gia To : Ky Moffet From : Barry Martin Date : Fri Feb 18 2022 10:28:00 Hi Ky! > KM> match the individual drive.

KM> Repair is only for data recovery; no failed drive is EVER KM> considered "working" after repair. My definition is probably looser: the repaired drive (rust or otherwise) is now working but I eye it with suspicion. I'd use it for something like Sneakernet or temporary storage/use, definitely nothing critical like for a Backup. > KM> Yeah, same reason I don't care that Bullet, who until I started > KM> rearranging hardware was doing duty as file server, is 14 years > KM> old.

Physical security makes sense for corporate, but for us, we KM> don't want to be bothered, when the worst hazard is falling KM> trees. Plus hackers are more likely to target businesses where tons of data like passwords, SSNs, etc., could be collected in one big swoop. More than likely a hacker isn't going to bother you or I to grab my bank account number. (They won't the password on my computer -- well, maybe the History -- darn!) I probably have a greater chance of a hacker attempting to snag my WiFi.

As far as physical KM> Yeah, and can put to use a lot more than the two drives handled KM> by the average commercial NAS with a consumer-practical price. In KM> a pinch my preferred case will handle ten HDDs. I don't want RAID KM> (cured of that by a summer spent recovering a friend's KM> RAID-mangled data) or anything but HAND OVER MY FILES AND NO ONE KM> GOES TO THE SCRAPYARD. No flaming hoops, just storage. Right. All I really need is backup storage for when something goes wrong. Even the old (antique!) NAS I have offers all sorts of options I've never used: Media Server, iTunes Server, Broadcatching (no idea what that is), Flickr/YouTube uploader.... Could probably get by with an external HDD! KM> I do have a very old actual for-really NAS here somewhere, but KM> haven't been able to get it to work. How old? IDE, KM> not SATA. Cisco, probably cost a fortune new. Came in some box of KM> free stuff. Interesting, but not useful. So when are you going to price SATA-to-IDE adapters?! Here I could break up the total storage device into portions: music BU to one HDD, data to another; the cameras monitoring what's going on putside could be to multiple small hard drives: they don't need to be to the same drive. I look at (essentially) /NAS/Unit 1/Camera 1, which could go just as easily to /NAS/HDD1 as /NAS/HDD8. > > > use some of the old/smaller HDDs > > > for end-directories (instead of a sub-dir on a huge/new HDD).

I don 't like to wait when I don't have to so not a good option for me. Actually was thinking more the output of the motherboard's port is set to go to the input of specific device only but suppose could just as easily do output to several device and whichever device is the correct one can then decode the data.

Spotted cows! ...I sort of have the theory lower-classed Pentiums, etc., were ones that failed to meet the upper-level standards: it works, just not at the top level.

All sorts of other KM> random RAM of every and no brand, no problem. So they're not on KM> my top buy list. I think the only brand I had problems with is Patriot but they immediately replaced essentially without question (I had done the extended MemTest+ diagnostic to verify to myself where the problem was already so any question was already answered). The usage also makes a difference (great! more variables!). Semi- following best for the Raspberry Pi's microSD card -- top of my head not recalling but essentially Brand A is good but only Model 1 as Model 2 is sluggish. Brand 2 is next best but if use as is better than Brand 1. ...Essentially depends on Reads, Writes. Also seems if a lot of writes then better off with a larger capacity card even though means a lot of unused space: each (segment) has only so many writes available, so if writing a lot then if to a small capacity card one uses the same (segment) over and over again, so exhausts/dies effectively sooner. If using a large capacity card the same number of writes are spread over more (segments) so effectively lasts longer. (Again I'm having an issue with terminology as don't know the proper name and details.) KM> I've used Lexar flash drives, but larger than 128GB like to KM> default to USB 1.0, and walking data over one bit at a time is KM> faster. "Oddly" Lexar drives were in one of the RPi studies and while great for other functions did abysmally poorly in the RPi. I odn't recall the size but seems the comparisons were using 16 and 32 GB cards. KM> In SSDs or NVMes, Sandisk/WD or Samsung. Only reason I have an KM> NVMe that's a PNY is cuz "cheapest one I could lay hands on til KM> we see if they work with this ...vintage... hardware and OS." Yup: if something may or may not work doesn't make sense to go with expensive. And of course usage: for example on this computer I want to access the information (data) fast so a 7200 RPM drive might make sense but for storage a 5600 RPM drive is probably mopre than enough, so I can save some money between those two options. (Think I have the numbers right.) KM> With the 3rd party driver, XP64 likes 'em fine. But Win7 threw up KM> in new and creative ways, and Win10 corrupts them (permanently KM> sets a dirty bit so they perpetually want "disk checking"). I'm more and more liking my decision to move away from Windows! ¯ BarryMartin3@ ® ¯ @MyMetronet.NET ® ....
