Does copy and paste have limits in XP?

[Guest Anthony Buckland]

The subject line may seem like a very odd question, but ...

I'm making my first acquaintance with large-capacity

SDHC cards as data storage devices. Using an 8Gb

Lexar card in an Optex USB2.0 adapter, I've tried

three methods of copying data from my VAIO desktop

(WinXP Media Center Edition with SP3, up to date)

to the card: Send To, Copy and Paste, and XCOPY

in command mode. In a sense, each method is a

variation on copying and pasting. And with each

method, once I get past a couple of GBy, I start

getting errors -- corrupted files, or actual Delayed

Write Failed errors.

 

Does copying and pasting have limits to the amount

of data that can be reliably handled, at some number

of GBy, or should I be considering poor quality in

the SDHC card or the adapter it's communicating

through? Should I just think of high-end SDHCs

of a presently unreliable medium?

 

Thanks for any thoughts.

Is the card formatted as FAT32? Maximum file size FAT32 = 4 gb.

Hope this helps.

Yes, it's FAT32, but no individual file I tried to put on it

exceeded 1.2 GBy.

Sounds like you might have bad data, bad HD with bad sectors, or bad

card. Trying buring the data to a disk then put that disk in another

machine and see if you can move it back and forth. Check your system log

to see if your getting and redundant cycle write read errors. good luck!

I don't think it's Windows' fault since you can copy and paste much more

that 8GB to a USB hard drive. Something could be wrong with the card reader

or its driver, the card itself, or the USB port.

 

I have a cheaply-made HP laptop and after about two years, the three USB

ports stopped working properly (bad physical connections) one after the

other. A port would suddenly stop working for a few seconds then would start

working again. I eventually took the laptop apart and replaced one

connector, but before I did I'd regularly get "delayed write failed errors"

after a few minutes when saving files to my external drive. You might want

to connect the reader to a different USB port to see if it helps.

Thanks to you and the other responders. The problem has been

solved. It was a case of a bad card. My USB slots are fine, other

removable media work fine, and the SDHC card misbehaved with

two separate reader/writers from different manufacturers.

 

The error phenomena included corrupted file contents, corrupted

file names, ridiculous output from Properties on the card (such

as one or more hundreds of GBy on an 8 GBy card), and inability

to reformat sometimes except in Manage on My Computer.

 

Aside from considerable time consumed, no problem, I'm way

inside the take-back-to-the-store time bracket.

Nice to read closure once in a while...
