Can't copy anything to the (two day old) SSD, but when I try to run a check on it (via properties/tools) it just stares at me with a progress bar that doesn't move.

I would check the cables and see if there is a manufacturer's tool that can help

If it’s USB try connecting the drive to a different port?

It is USB - haz tried connecting to different ports.  On different port it now does the check in <1sec and returns nothing.  Problem persists.

using chkdsk I am seeing corruption was found while examining files in \folder\sub_folder

Could I solve the issue by just deleting those files?

You could try reformating the drive unless you are using it as boot.

It's to use as a backup for things wot I don't want to lose - e.g. photos and my music collection.

With a transfer rate of ~3MB/sec it took most of the day yesterday to transfer over the files - so reformatting is the least prefferableoption.

Yeah, so error persists but a number of files have gone - so I have gone the reformat route.  Yay.

I may go for a refund as it has crashed within 24 hours of use (not a positive for a backup drive).

Also, why do they persist in selling drives with a mislabled storage (e.g. the label says 2Tb but it's 1.81Tb).

You sure it’s that slow? USB (super speed) is of the order of 5 Gbit/s  even spinning rust max out that rate.

Probably as one is measuring incorrectly in multiples of 1,000., the other in multiples of 1,024

Base 10 (decimal) versus base 2 (binary) innit.
Or to put it another way, physicists versus computer scientists.

A gigabit is nearlly always 1000 megabits because networking standards are predominantly influenced by electrical engineers.

(Crosspost, but what the hell)

Also, why do they persist in selling drives with a mislabled storage (e.g. the label says 2Tb but it's 1.81Tb).

+1. I have wondered that for many years.

A couple of issues:

1) For convenience, and because 2^10 isn't far off 10^3, Computer People use the SI prefixes to denote powers of 2, so k means 1024, M means 1048576, and so on.  Meanwhile the rest of the world (but notably in this context Telecoms People), use them in the traditional power of ten sense, where k means 1000, M means 1000000 and so on.  This isn't usually a problem until you're trying to work out how long a file of foo gibibytes[1] will take to transfer on a network link of bar megabits per second, or similar.

At some point the marketroids worked this out and realised that if they used the decimal prefixes in their specifications, they could make their storage devices sound bigger.  All the manufacturers quickly followed suit, so as not to lose the arms race, even if just amongst their less literate customers.  And now we're stuck with it.


2) Filesystems have overheads.  You don't, outside of a few specialist contexts, just spew data to a storage device bit for bit.  There's going to be some metadata to say where the file is (bear in mind it might be fragmented all over the disk, so this is non-trivial), what it's called, permissions and so on, as well as provide error-checking/correction.  More subtly, the filesystem will divide the space up into blocks, and only store [part of] a single file in each block.  Bigger blocks mean less metadata is needed, but more space wasted if the file is smaller than the block size (it's a judgement that you have to make when formatting a disk, based on what it's intended to be used for).  This is how a file might appear to grow or shrink when copied from one filesystem to another, and why your file manager might quote different values for "file size" and "size on disk".


3) People sometimes confuse bits and bytes in abbreviations, because Non Computer People who aren't German aren't used to upper and lower case being an important part of the spelling.  GB is gigabytes, whereas Gb is gigabits.  The former being 8 times bigger, which is small enough a difference that you might not notice the way you would if you confused millilitres with megalitres.


[1] In a belated attempt to reduce confusion the IEC came up with new prefixes (kibi, mebi, gibi vs kilo mega, giga) for the binary-derived values.  People sometimes use them.  My recommendation would be to approach the specification of storage devices with the same degree of caution that one approaches the sizing of bicycle tyres, and to assume the decimal meaning unless it's the funny 'i' version.
Careful, Kim. Your sarcasm's showing...

I'm using a Win7 machine.  Super speed is not a term commonly used.

A couple of issues:

Thanks, Kim. My issue is not with the maths but from a Trading Standards perspective.

If, say, Coca-Cola sold cans of drink and said the can contains 350ml but we only get 330ml to drink, Trading Standards would not allow such advertising. Clearly, a can of Coke cannot in all practicality be filled right to the brim (or ring-pull) and so we lose 20ml of the can's capacity as an operational overhead. But Coca-Cola doesn't tell us advertsise the 350ml can but its 330ml of Coke, so all is well with Trading Standards.

With disks, the full size of a disk may be 2TB, to use fd3's example, but we know that the OS needs to use a bit of that space to manage the drive, hence we get 1.81TB of usable space. I am surprised that Trading Standards has let this slip through the otherwise fairly watertight net.

Reformatted, copied files over, half way through same error again.

What's a decent price for cloud storage?  2-500GB would do.

Google Drive is free for the first 15gb but it's google...
One Drive only seems to come with Microsith 365, 60 quid a year
Google Drive is 25 quid a year for 200Gb and 80 for 2Tb; you only get Googles diabolically bad stuff though, and they'll cancel the stuff you actually use.
I got as far as drop box's pricing page then choked... ok it's 3Tb but it's 16 quid a month, sod that.

Microsith keeps urging me to log in to my One Drive, which apparently I unwittingly acquired when I bought a new computer. I do not have 365. I believe it costs money, which I do not pay.

I think that I pay about £72 for backblaze, for backup storage. Unlimited size - I've got about 3.5TB backed up.

One drive isn’t Office 365 and pre dates it by some years.

The problem is they're correctly describing the disk as 2TB (decimal), which would seem pretty watertight from a trading standards perspective.  They only need to point at the relevant IEC/ISO definitions.

That you've grown up thinking of tebibytes as terabytes, and indeed that your OS may use 'TB' when it should technically be using 'TiB' isn't really their fault.

It's more like buying a "300mil" length of whatever and getting upset when it turns out to be 7.62mm long.

(Filesystem overheads are irrelevant unless it's a NAS or something where the vendor is providing an OS and filesystem.  It's up to you what you do with the disk.  You could write a .tar directly to it[1] for no overheads if you wanted to.)

I appears that I failed to quote the post to which I was replying, that said something about One Drive seemingly requiring purchase of 365.

That brings back memories  .. . . . .

My last interaction with tape was in 1999. One of my employer's subsidiaries was switching to a new billing system & needed to keep a lot of archived phone call data because Greek law, so I had to hunt through documentation for all the changes to record formats then write procedures to detect the changes & reformat as necessary while writing to media their new system could read. Cleverly, they'd maximised the use of each tape by not changing tapes when formats changed.

Kicked it all off then hung around until it was clear it was working then flew home, leaving some poor buggers in a room full of tape drives somewhere in Athens changing tapes for days on end. Can't remember how long it took to do them all.
