USB 2.0 Data transfer slow/iMac

[LordUn]

Hi guys,

need some feedback - im needing to reformat an external USB 2.0 Seagate 7200 RPM hard disc, and so need to store the date somewhere else initially. I decided to put this onto one of the new imacs while I did the deed. The data needing to be backed up is around 60GB - the transfer after 6 hours was only around half of this amount. What could be the problem?

Also, for future reference, is there an easier way to reformat a disc from NTFS to FAT32 based so the drive is read/write on both windows and mac?

Cheers!😕

which imac and if you have it plugged into the keyboard it is only a usb1.x port. in the end its usb and its still technically a serial port. usb also fluctuates with powersupply but its an external hd so that should not be an issue.

final comment - spend a few dollars extra and get firewire - much more reliable in my experiences

Hmm, you're getting barely 12MBit/s, which is 1.1 speed. I consistently get 27MB/s (that's Megabytes per second) from my USB drive (which is still slower than the 40MB/s from my firewire drive).

So, to emphasise SpankyPenzaanz point, do you have the drive plugged into the keyboard?

if its a hub make sure its has its own powersupply and make sure it is on and etc.

What kind of iMac?

I should clarify for all....

It is a seagate USB 2.0 drive, and I am a switcher customer so recylcling my drive. The drive is 7200 Spin, and self powering.

It is on a new Imac 20" core 2 model, and it is plugged into a USB 2.0 port on the rear of the iMac - I have tried several ports, it is incredibly slow compared to my PC systems in use also.

I will use one of them to backup right now, but its still not solving my problem of atrocious performance over USB 2.0.

Any suggestions? Thanks for the input

is it a usb2.0 cable...I know it may sound trivia

 

[LordUn]

Yeah, it is...

is it a usb2.0 cable...I know it may sound trivia

unfortunately it is the package that came in the pack - im a little stumped as to why performance on any of the USB 2.0 ports is so slow - it ramps fine in XP

I'm having some USB issues in 10.4.8. It only seems to make my computer sluggish and doesn't effect transfer speeds.
