Re: SSD reliability and interface discussion (Previously: HDD issues)
There isn't normally a power supply in thumb drives. Perhaps it's an e-ink display that only requires power to change?
Seems so http://www.lexar.com/about/newsroom/...paper-display-

Re: SSD reliability and interface discussion (Previously: HDD issues)
Yea, the article I read was talking about reel to reel tape. It seems to me some very old movies are still intact. They are black and white and do not entail color. They may also had a different a process to make them. I would think storing digital signals on tape would be a very basic process unless one first converted them to a analog signal before recording. So there is a lot of unknowns and that is usually the case when people make statements. I guess one would have to have a control test to verify these statements.
Also, I'd love to see them digitally restore some of the good old cartoons like Topcat and Johnny Quest, Transformers, G.I. Joes, TMNT, Tiny Toons, Tailspin, etc.-- Law of Expanding Memory: Applications Will Also Expand Until RAM Is FullComment

Re: SSD reliability and interface discussion (Previously: HDD issues)
Yeah, a little off topic here (well, way off topic from the title of the the thread!) I got a Top Cat cell, autographed by Hanna and Barbera. It came with a certificate of authenticity, but I'd like to verify that it's legit. I took it apart once and the the cell isn't autographed, there's a transparency that's autographed and then placed over the cell. Maybe they used the transparency to copy their signature? Or maybe they did it so they wouldn't destroy the cell. I'd love to find the actual episode which has the cell, you know, to verify that's real as well. It was entitled something like, "Topcat visits the mayor". The cell itself is a picture of a room, blue coloured walls, yellowish / orange coloured floor, a window in the background, etc.

Re: SSD reliability and interface discussion (Previously: HDD issues)
This has to be one of those FWIW posts. Eh?
Last May, I bought my first SSD, directly from PNY. It ran for two months and then refused to boot up my PC one morning. There was nothing I could do to revive it.
So, I called PNY's support hot-line and I found out that without the original purchase order, they would do nothing for me.
Then, still needing an SSD, I went to Amazon.com and found a SanDisk SSD of the right size and price for me. I bought it, had it here in two days, installed it, did a restore of my last backup image file and it's been running Great ever since.
With the SanDisk SSD, I got a nice disk management package including TRIM, which I didn't get with the PNY drive.
I now have TRIM set up to run once a week.
BOY! Is this new SanDisk SSD ever FAST!
Boot-up takes only about 10 sec's and Shutdown less than five Sec's.
It's truly amazing!
Cheers Mates!

Re: SSD reliability and interface discussion (Previously: HDD issues)
my police friend doug had a PNY drive, and it booted fine but once it got into windows transactions slowed dramatically, he could not have two windows opening at the same time without the drive choking. I suggested Samsung 850 ProCap Datasheet Depot: http://www.paullinebarger.net/DS/

Re: SSD reliability and interface discussion (Previously: HDD issues)
a quick search around the web shows that pny is notorious for not honoring their warranty along with their drives having a high failure rate.
their drives also dont seem to have any wear leveling and trim from what uranium described. in short, stay away from no name brands for ssds unless u dont care about the warranty or the drive failing.Comment

Re: SSD reliability and interface discussion (Previously: HDD issues)
Topcat would really be cool to restore. I guess to verify something like that I would find out who was responsible for producing the cell and ask them how you can verify your copy. Other than that you would have to find a person who specializes in authenticating similar types of items. The latter will most likely want to charge you for their services.-- Law of Expanding Memory: Applications Will Also Expand Until RAM Is FullComment

Re: SSD reliability and interface discussion (Previously: HDD issues)
I had a similar problem but with an Ultra modular power supply. Bought two of them once. Both died. I had registered each of them. They both came with a lifetime warranty. When I called to get them replaced, they replaced the first, but the second one they claimed I needed the original receipt. Even if I had kept it, it would of been totally faded. We searched everywhere for it and found some receipts that where completely faded (we keep receipts in two separate places. One for lifetime ones, one for limited ones). Anyway, they refused to replace it with the receipt. They said the warranties weren't transferable and without me having the receipt, they couldn't prove I wasn't the original buyer. I asked if I could send in a photocopy of my license or something and they said no, I needed the receipt. Never bought an Ultra power supply after that.-- Law of Expanding Memory: Applications Will Also Expand Until RAM Is FullComment

Re: SSD reliability and interface discussion (Previously: HDD issues)
another reason to be careful of lifetime warranty gimmicks. often they are used to fool ppl into buying a product and then they cook up half-cocked reasons not to honor the warranty or to downgrade it to x years warranty. only way is to create as much awareness about the brand not honoring their warranty and to stay away. in short, serve your revenge very coldly by making them go out of business.Comment

Re: SSD reliability and interface discussion (Previously: HDD issues)
It would be nice to buy non-MLC NAND based SSDs for reasonable prices. Theoretically, they should only be twice the price, because the density is half. But this is not the case, SLC is always professional grade and so they are stupidly expensive.
MLC NAND does 3,000 cycles, SLC NAND does 60,000+. So there is a good reason to want SLC. And let's hope TLC NAND doesn't get into SSDs any time soon, that has a cycle life around 600 cycles.
As for OCZ, I have two old SSDs (Solid Sata II 120GB) which are still going, about 7 years old, my brother gave them to me when he upgraded. However, not really used them in a while. I put one in my laptop which massively sped it up, over the stock 160GB HDD.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

It was a learning experience. Now, with lifetime warranties, we scan the receipt with the PC and still keep a physical copy, just in case they "require" a receipt.

Re: SSD reliability and interface discussion (Previously: HDD issues)
waaa. thx so much for the article u wrote. so the moral of the story is to not be the guinea pig and to just stick to tried and tested tech like mlc based drives. cuz it seems like tlc tech is so new that even samsung themselves do not know how their own invention behaves or actually works for that matter...
i remember when ssds first came out, it took quite a few years to figure out the issues plaguing ssds. kudos to the anandtech guy for figuring out the read-modify-write issues with early ssds and to implement garbage collection to avoid the problem.
i forsee at least another 3 years or so for them to figure out and fix the issues plagung tlc drives. if not, tlc nand will just become another ugly stain in the memory of ssds and we will require another new innovation to take flash memory forward cuz these days, hard drives are really becoming more and more crappy... look at all the 1 and 2 year warranties hard drives these days come with. i really relish the days during the dvd era when hard drives had to come with at least a 5 year warranty or no one would buy them...Last edited by ChaosLegionnaire; 10-06-2015, 07:44 PM.Comment

Re: SSD reliability and interface discussion (Previously: HDD issues)
It seems to me that if they use spin computing with a hard disk this might solve some problems. If one had a disk made up of and array of read/write spin pick ups that matched up with a hard disk. The read would be easy as the magnetic field of the bits on the hard drive could be pick up on the receptive disk. the hard part would be actually creating a large enough magnetic field to change the hard disk.Comment

by welpI have a PlayStation 5 CH-1215A with a Disk drive not reading disks anymore. (accepting and ejecting very slowly.)
Knowing the PS5 has a married daughter board for the disk drive I made sure to use that and replace the rest of the disk tray as it* was owned previously by an indoor smoker.
Once the job was complete and put back everything together, I tried to insert a disk with no luck at all...
So, I checked voltage going from the ps5 to the daughter board and am only getting the 5V rail.
With that knowledge I preceded to check all the fuses for the 12v rail on the main... -

I have an really very weired issue with ASUS ROG STRIX B550-I GAMING.
Some NVME (PCIe) SSD's are not working correctly in the second M.2 socket. An example of it is the SAMSUNG SSD980 1TB NVME SSD.
Some other NVME (I have only smaller ones) disk do work without any problem, also SAMSUNG disks, eg an MZVPV128HDGM-0000.
The behaviour is also really very strange, i.e.:- The disk shows always up in BIOS - so it is recognized, so far so good
- POST-ing with this disk with fresh Windows 24H2 installation (done in the M.2_1 socket) in the M.2_2 socket

by madura2010Today recieved hp model 17-f100nx laptop with no power.(motherboard=DAY11AMB6E0) after that repaired +1.05v section due to faulty buck converter.after that power issue fixed and laptop turns on.But "no bootable 3f0 error displayed".so then
i checked the connectivity of ribbon=good communication with hard and motherboard
changed hard disk and checked=3f0 error persist
sata power=+5v available
Then checked data capacitors=all good
Then checked data lines path connectivity to pch=all good

by chth96I bought 6 second hands odd $5 at a flea market and I found that 2 odd(GCC-4521B,TS-H192) won't read any disk.
But I measured all ESR value of SMD capacitor which is located on the TS-H192's PCB and replaced two capacitor which has higher ESR value.
And To My joy,this TS-H192 odd finally recognized burned CD as well as pressed CD.😂
But there was no more good fortune for GCC-4521B..In order to dead GCC-4521B back to life, I replaced three capacitor which has higher ESR value and I rubbed silicon grease on the every glides.I even brushed lens with cotton swab which was soaked...02-13-2024, 07:31 AM -
by duwaneHi All.
Sorry ahead of time for the text wall. This is a strange problem and I have tried to explain it as best I can. I realise this is a hardware forum (mostly), but I am still not sure if this is even a hardware fault! I am hoping that someone more knowledgeable than me in the area of understanding installation logs, or someone that has had a similar issue in the past may have some ideas of what might be causing this.
The issue:
Unable to do a clean install of any macOS versions supported for this model, even after fully erasing and formatting the internal SSD,... - Loading...
