Unsuccessful backup. I/O device error (0x8007045D)

I just bought a new computer with Windows Vista Home Premium. I cannot
create a backup of recovery files on a DVD-R disc. Everything starts off
fine, then at the end this error comes up:

The backup did not complete successfully. An error occured. The following
information might help you reslove the error. The request could not be
performed because of an i/o device error (0x8007045D)

Please help me. Much appreciated.

You might get an educated answer if you put a little information in your
post like computer type, drive type etc. Lacking that use some of that
customer support from whomever you bought it from. Find out if the hardware,
software, drivers are all Vista ready.

Here are my computer specs:
Hewlett-Packard - Pavilion 4600+ Desktop a1730n
AMD Athlon™ 64 X2 dual-core processor 4600+; 1GB DDR2 SDRAM; DL DVD±RW/CD-RW
drive; LightScribe labeling; 320GB hard drive; Windows Vista Home Premium

I am trying to make a backup disk of recovery data from drive D.
I assume the programs would be Vista ready as everything was included with
the computer. However you just never know, I will try and contact customer
support also as suggested.

Thanks again.

Happened to me too in both file backup and computer backup. I supposed MS will address in the future. For now, go to the system settings and uncheck the drives so they no longer create shadow copies (restore function in Vista). Apply the new settings to erase all existing shadow copies. Then reset by checking the boxes you unchecked. Now try to backup the whole computer again. It appears a shadow copy error is conflicting with the backup process. Once you delete all shadow copies (restore points) it will work.

Hi, I am having simillar problem with my Toshiba Satellite M30. I am trying
to back up my files copying them to a blank DVD-R but the computer doesn't
seem to recognise the disk and the same message appears: The request cannot
be performed because of an I/O device error. Any suggestions please? I am
going crazy here. Thank you very much.

AMD 2.2 Ghz
ATI Radeon
1 GB RAM
4 Drives.
One external, WD My book 500 GB.
Vista Ultimate

I try to use different software to do a backup to the WD drive, and I
get the Error 0x8007045D.
I tried to move large files (almost a GB in size) to the WD drive, and
I get the same error.
I have tried to move the exact same file from two other different
drives, to the WD drive, and it gave the same error message.

I think MSFT needs to determine what is causing this issue, since it
appears to be happening to numerous people with very different
setups.

Same problem over here too.
I'm able to copy smaller files (3 GB and under), but not my entire
"music" folder which is 40 GB or so from my IDE backup drive to my
RAID 0 SATA array. Getting the exact same error.
Now, since files 3 GB or less copy, but rather slowly, I think it
might have something to do with the paging file or virtual memory. I
have it set to 3 GB. Not sure but I keep hearing about a hotfix M$
made but you need to call their support and possibly pay for the
hotfix? This is ridiculous to me and I won't try it.
Anyone else have any luck?

Noggin, your post in this thread helped me too. See my post titled "Backup
failure 0x8007045D (I/O device error)". After doing your suggested settings,
my complete backup went perfectly. I will now consider my post solved, but
have a question for you: will this procedure be required each time I do a
complete backup? Reason I ask is that I have no problem backing up files,
it's just the complete backup that was causing problems. Thanks.

This problem seems to be widespread. You might want to
read this forum. I just entered the error code in a web search engine
and got many hits.

I'm having the same problem when i'm just copying files onto a usb
drive. I tried the shadow copies method and it still doesn't work. I
also saw someone mentioning permission problems as a possible cause of
this and I checked and that didn't work...any other ideas anyone?

For whatever its worth, I had the same problem with a Dell Dimension E520
with internal DVD burner/reader. Inserting a brand new DVD solved the
problem.

I`m new here. I have 2 external HDD, one 1TB is always connected to PC
and another 250GB pocket one is only for additional back up of back up.
Both of them were formatted in order to be able to do Back Up PC. I was
successful only 2 times with back up and now it doesn`t work. I get this
error I/O device error (0x8007045D). I tried advice as quoted here
below, but unfortunately it didn`t work for me. I think my shadow copies
are in ext. HDDs. I deleted my previous back up, but when I tried to do
again it shows me that I have 2 older ones, though I deleted them and
cannot see it.
I formatted again smaller HDD with less data (back to default) but it
still didn`t work:cry: I got another following error after that: "The
system cannot find the file specified 0x80070002"
How do I delete shadow copies from ext. HDDs without formatting it?
Please help.

I, too am having problems copying files from one drive to another. After
reading numerous posts on many sites I tried the above solution (delete
restore) but this did not help. I have a Compaq running Vista 32. Any
ideas anyone, please.

I've had this backup error many times, but when I delete the restore
points it usually works. However, NOW it isn't working. Have tried 3x
today, and the backup won't work.

When will microsoft address this??? :mad:

Is there anything else I can try?
